- [Ulpatek Filter Sales Manager Ganim Dokuyucu answered Daily Show newspaper’s questions](https://www.ulpatek.com/ulpatek-filter-sales-manager-ganim-dokuyucu-answered-daily-show-newspapers-questions/): Before discussing ULPATEK, it is necessary to briefly mention Tetisan Industrial. Founded in 1978, Tetisan is a company with 37 years of history. In its early years, it primarily focused on mechanical installation contracts. Later, in the 1990s, in conjunction with developments in the Turkish textile sector, Tetisan began providing and installing predominantly industrial type air conditioning and ventilation products to companies operating in the textile sector. We constructed facilities for leading companies in the sector such as Akın Tekstil, Edip İplik, Bahariye Mensucat, Ozcanlar Tekstil, and Boyteks. During this period, Tetisan, under the leadership of Prof. Dr. F. Taner Özkaynak, began implementing hygienic air conditioning systems primarily in pharmaceutical factories. We also started manufacturing air handling units used in hygienic air conditioning systems during this time. Tetisan successfully implemented these systems and continues to do so in many pharmaceutical factories such as Roche, Novartis, Sandoz, Pfizer, Abdi İbrahim, Mustafa Nevzat, Deva, and Sanovel İlac. Additionally, Tetisan successfully installed hygienic air conditioning systems at Danone in Lüleburgaz and Pınar Et facilities in İzmir Kemalpaşa. In the early 2000s, we accelerated the production of hospital air conditioning equipment such as air handling units compliant with DIN 1946/4 standards, laminar flow units, HEPA filter housings, and intake grilles. We produced Turkey's first compact operating theater hygienic air conditioning unit (HYG-30) with support from TUBİTAK and TTGV. In the past, Tetisan used filters from a European brand whose ownership changed several times. Each change also changed how the brand was represented in Turkey, which caused confusion in the domestic market and problems with quality and delivery times. In 2005, Tetisan transferred the production rights (know-how) for air conditioning units to Airfel A.Ş. Parallel to these developments, ULPATEK Filtre was established in 2007 under the leadership of Prof. Dr. F. Taner Özkaynak, with contributions from U.Tamer Özkaynak, Recep Ekinci, and Ganim Dokuyucu. Our company has developed a wide range of products consisting of coarse, fine, EPA, HEPA, and ULPA filters of the highest quality, compliant with EN 779 and EN 1822 standards, capable of meeting the filtration needs of all HVAC systems, from the simplest ventilation systems to clean rooms. We first introduced our products to the market by exhibiting them at a SODEX fair in May 2008. ULPATEK was established to provide high-quality filtration solutions against chemical and biological particles resulting from industrialization and population growth, develop products for this purpose, and play a role in solving this global problem.

- [Comparison of Filter Standards: ISO 16890, EN 779 and MERV](https://www.ulpatek.com/filter-technology/comparison-of-filter-standards/): ISO 16890 is the current international standard for air filters used in general ventilation. It replaced EN 779:2012, which was withdrawn across Europe on 30 June 2018. There is no exact one-to-one conversion between the two: an F7 filter is not "equal to" one specific ISO 16890 class, only to a range of possible classes. ISO 16890 classifies a filter by how much of the airborne particulate matter it removes – ePM1, ePM2.5, ePM10 or ISO Coarse – instead of by efficiency at a single 0.4 µm particle size. MERV (ANSI/ASHRAE 52.2) remains a separate North American system and also has no exact equivalence with either.
- [ISO 16890](https://www.ulpatek.com/filter-technology/ulpalab-filter-test-labs-2/5686-2/): ISO 16890 standard is the new standard that has replaced the EN779: 2012. This standard covers Coarse filters (Class G), Medium filters (Class M) and Fine filters (Class F) and eliminate the insufficient points of the old standard. With this change in standard, filter users will be able to choose the filter much more accurate according to their needs. ISO 16890 standard considers for the particle size (Particulate Matter = PM) between 0.3 μm and 10 μm for efficiency evaluation. Filters are divided into 4 groups. ePM1 95% ePM1 90% ePM1 85% ePM1 80% ePM1 75% ePM1 70% ePM1 65% ePM1 60% ePM1 55% ePM1 50% Requirement ≥50% Initial Efficiency ≥50% Discharged Efficiency ePM2.5 95% ePM2.5 90% ePM2.5 85% ePM2.5 80% ePM2.5 75% ePM2.5 70% ePM2.5 65% ePM2.5 60% ePM2.5 55% ePM2.5 50% Requirement ≥50% Initial Efficiency ≥50% Discharged Efficiency ePM10 95% ePM10 90% ePM10 85% ePM10 80% ePM10 75% ePM10 70% ePM10 65% ePM10 60% ePM10 55% ePM10 50% Requirement ≥50% Initial Efficiency No discharge requirement ISO Coarse 95% ISO Coarse 90% ISO Coarse 85% ISO Coarse 80% ISO Coarse 75% ISO Coarse 70% ISO Coarse 65% ISO Coarse 60% ISO Coarse 55% ISO Coarse 50% Requirement ePM10 < 50% Initial gravimetric arrestance (Am) No discharge requirement Test procedure of the ISO 16890 standard begins with measuring the efficiency of an air filter at a particle size range of 0.3 μm to 10 μm.The Filter is subjected to an isopropanol vapor atmosphere to eliminate efficiency of electrostatic mechanism.Isopropanol vapor atmosphere conditioned Filter tested again to measure the minimum efficiency ePM1,min and ePM2,5,minEfficiency for each PM size is calculated by the mean of both conditioned and the conditioned filter.The efficiencies for ePM1 are calculated for the particle size 0.3 -1 μm , ePM2.5 for the particle size range of up to 2.5 and ePM10 for the particle size range of up to 10 microns.Calculated efficiency values are rounded to the nearest lower value according to the efficiency values in the ISO 16890 classification groups.For example; According to the test result, the F8 class V-Compact Filter is classified as “ISO ePM1 70%”. This means that the filter separates 70% of PM1 particles. The “e” stands for efficiency in combinition with the particulate matter (PM).Efficiency is given according to PM10, PM2.5 and PM1. The dust holding capacity is calculated for ISO A2/AC Fine synthetic test powder. Initial gravimetric arrestance efficiency is calculated. The filter differential pressure drop (Δp) is measured at the nominal air flow rate. For efficiency evaluation, the particle size is between 0.3-10 μm. The efficiency is measured separately according to the particle range. The efficiency measurement is repeated 24 hours after the IPA process. The «ePMx efficiency» is calculated with the measured efficiencies. The filter performance is determined according to PM10, PM2.5 and PM1. Separately efficiency results in each particle channel. The process is considered when selecting the filter. Global (ISO, International Organization for Standardization).
- [ULPALAB Filter Test Labs](https://www.ulpatek.com/filter-technology/ulpalab-filter-test-labs-2/): Efficient air filters (EPA), high efficiency air filters (HEPA) and ultra low penetration air filters (ULPA) are classified and tested according to EN 1822 standard for ventilation and air conditioning systems such as cleanroom applications.
- [EN 1822](https://www.ulpatek.com/filter-technology/ulpalab-filter-test-labs-2/en-1822/): Efficiency Particulate Air Filters (EPA), High Efficiency Particulate Air Filters (HEPA) and Ultra Low Penetration Air Filters (ULPA) classified and tested according to EN 1822 standards. These filters are used in many industries including, pharmaceutical manufacturing, Bio-Tech,Electronics, Aerospace, Hospitals, and more. There are independent tests for EPA / HEPA / ULPA class filter and filter media according to EN 1822. 1. Efficiency test of the filter fiber: An efficiency test performed by the filter material manufacturers at the nominal speed and MPPS. 2. Filter leak test: It is the test done at MPPS by using particle counters. An alternative to this test is the oil smoke leakage test for H13 and H14 class filters. 3. Filter efficiency test at MPPS: A method of measurement by scanning the filter surface under test conditions. Efficiency is measured with the particle counters used in this test. MPPS: Most Penetrating Particle Size
- [GAS PHASE FILTRATION](https://www.ulpatek.com/filter-technology/gas-phase-filtration/): The EN 779 standard will be canceled completely mid of 2018, and ISO 16890 will be used as a new standard for Air Filter. The main change in standard allows the user to make the filter choice much more precise according to the needs of the users. Ulpatek Filtration has taken pioneering steps to inform the sector about its ISO 16890 standard by giving its brokers and business partners priority to Turkish and English information brochures.Airborne pollution sources are various which can be from natural sources like volcanos, thermal sources, pollens, sand storms and from industrial life like factories, automobile emissions, jet fuels, garbage dumps etc.
- [Applications](https://www.ulpatek.com/applications/): It is very important that the HEPA/ULPA filters should be leakproof, have enough filtration area and used in nominal capacities in the pharmaceutical industry where the standards and regulations are very strict.
- [EN ISO 14644-1](https://www.ulpatek.com/filter-technology/en-iso-14644-1/): ISO 14644-1 defines the classification of air cleanliness in cleanrooms and associated controlled environments exclusively
- [Chemical Filtration](https://www.ulpatek.com/filter-technology/chemical-filtration/): Gas phase filtration and particulate filtration work together for acceptable indoor air quality in controlled environments. Gas pollutants are filtered with Ulpatek's gas phase air filters which are produced from one or mix filter media. Particulate pollutants are controlled with particulate filters which are mentioned in related standards ascourse, fine and absolute filters. Gas phase filter media (pellets) generally are produced using carbon, zeolite, alumina or coconut-based media. Gas phase filtration occurs with the two different methods which are physical and chemical.Process control systems, data centers and other rooms that have instrumentation which has to be environmental controlled must supply G1 classification according to ISA requirements. Achieving room ventilation design requirement must supply a minimum room pressurization of 1-3 air changes per hour and recirculation of 6-12 air changes per hour. Temperature is typically 22 °C (±2 °C) with humidity lower than 50% relative humidity. Tightness of the room is also another parameter while defining the design parameters. In addition to Petrochemical Refinery these parameters, hazardous pollutants are main parameter which must be removed from the enclosed space. Contamination concentration levels are defined in ANSI/ISA-71.04.
- [Mechanism of Air Filter](https://www.ulpatek.com/filter-technology/mechanism-of-air-filter/): Filters have different effects that help to catch dust. These;
- [Effect Of Measuring Method](https://www.ulpatek.com/filter-technology/effect-of-measuring-method/): Work done under the sponsorship of ASHRAE and private organizations such as filter manufacturers showed that the percentage distribution of particle sizes in the atmosphere depended significantly on the method of measurement. Figure attached shows the relationship between particle size distribution and measurement. For instance, particles smaller than 1.0 micron comprise only 3% by weight of all atmospheric dust particles, but make up 98.5% by count.On the other hand, atmospheric dust particles in the 5.0 to 10 micron size range comprise 52% by weight, but only 0.175% on a count basis. Note that almost all the particles in the atmosphere are less than 1 micron in diameter.
- [The Air We Breathe](https://www.ulpatek.com/filter-technology/the-air-we-breathe/): Air is a mixture of gases composed of approximately 21% oxygen, 78% nitrogen, 1% argon, and traces of other gases. The air we breathe also includes particulate material and gases generated by nature, by man, and by industrial processes as seen in the Figure. We are concerned with the particulate matter and gases which influence our health or comfort, which damage the spaces we occupy, or which effect the products or components we are manufacturing.
- [News](https://www.ulpatek.com/news/)
- [Pharma](https://www.ulpatek.com/applications/pharma/): It is very important that the HEPA/ULPA filters should be leakproof, have enough filtration area and used in nominal capacities in the pharmaceutical industry where the standards and regulations are very strict.
- [Industrial](https://www.ulpatek.com/applications/industrial/): Ulpatek offers filters, equipments, and systems solutions for many industries, including pharmaceutical factories, hospitals, food production facilities, commercial buildings and power plants. From oil mist eliminators and dust collectors to gas adsorption filters for corrosive gases and complete process filtration systems, our solutions in this segment are designed around the exact needs of modern manufacturing and industrial processes - ensuring the protection of human health, the environment and equipment. While our filters and systems increase the quality of the products in the process, also protecting the health of people and other living things, the environment and the equipment.The most important issue in industrial applications is corrosion control. Control rooms with electronic equipment, data centers and similar control areas must comply with G1 class according to ISA requirements. The room ventilation design is made according to the air change of 1-3 hours per hour for positive pressurization and 6-12 hours per hour for air circulation. The temperature design is 22 °C (± 2 °C) and the relative humidity is less than 50%. Another parameter that influences design criteria is the leakproofing of the room. One another main parameter that must be removed from enclosed spaces is hazardous gas pollutants.Odors are mainly source by the industrial fields such as biogas, wastewater treatment facilities. Toxic gas cleaning units are generally used for the filtration of dichlor (Cl2), sulfur dioxide (SO2) or ammonia (NH3) gases.
- [Commercial Buildings](https://www.ulpatek.com/applications/commercial-buildings/): People spent most of their time (average 90%) in enclosed spaces. This is why commercial buildings are utilising air conditioning filtration systems to improve the comfort of occupants, and ensuring the highest level of indoor air quality to avoid sick building syndrome (particularly in the workplace) is a primary concern for building owners and operators. In closed areas, fine and ultra-fine contaminant particles from external sources of emission (external air, windows, leaks, etc.) and internal emission sources (cigarettes, cooking and vacuum systems, etc.) are defined as factors that increase health risk. The level of pollution in enclosed areas is typically two to five (but can be up to 100) times higher than the level of pollutants found externally.There are basically three issues when designing climate systems to reduce these harmful pollutants and to provide the fresh air required for humans (34 m³ / h (20 CFM) outside air requirement - ASHRAE 62-89).
- [Power Plants](https://www.ulpatek.com/applications/power-plants/): The energy needs of developing countries are increasing day by day. It is possible to meet the increasing energy demands by investing in new gas turbine power plants. Filtration is at the head of the most basic requirements for the operation of high-performance, long-life and efficient plants. Dust and particles on gas turbine blades can damage these equipment’s and cause their efficiency to decrease or even to fail over time. To prevent this, correct air filter stages and filter models should be installed in order to provide the desired efficiency of the air inlets of gas turbines.Also, increasing the quality of the air entering the gas turbines is an important factor for the effective use of power plants. In this way, there will be more efficient combustion and energy saving. After all the process, the exhausted air should be also filtered. With the right filtration, the shelf life of the equipment will be more longer and the working efficiency is increasing.
- [Food & Beverage](https://www.ulpatek.com/applications/food-beverage/): Ulpatek filters and systems equipments are used in national and international beverage and food production facilities. It is very important to use the appropriate filter stages, filter classes, filter numbers to keep the air quality at the desired level in such a high standard requirements.

- [HEPA FILTER UPGRADE IN AIR HANDLING UNITS, THINGS TO PAY ATTENTION](https://www.ulpatek.com/products/articles/hepa-filter-upgrade-in-air-handling-units-things-to-pay-attention/): Recently, after the new type of coronavirus epidemic, we are getting questions about installing HEPA filters in air handling units of commercial and public buildings such as offices, schools, shopping centers, sports facilities. The guide published by REHVA (REHVA COVID-19 guidance document, 17 March 2020) contains explanations about this issue. However, those who want to take precautions by using HEPA filters in the air handling unit should consider the following points.1-It is important to be aware that the air handling units used in comfort applications are not suitable for hygienic application and the filter mounting frames inside unit are not suitable for HEPA filter. It will not be possible to provide 100% sealing between the HEPA Filter and the mounting frame. Leakage from these points will be seen in validation tests, the efficiency expected from the HEPA filter will not be achieved due to leaks.2-The differential pressure of HEPA filters are very high compared to filters (F7, F9 or PM1) in the last stage of AHU’s in comfort applications. In order to operate in the same air flows, it will be necessary to use much more filtration area in HEPA filters compared to standard AHU filters. However, this is not possible with Rigid or V-Compact models.3-If the HEPA filter will be used without reducing the air flow of the AHU, revision should be made in the filter cell. This revision can be done with changing the mounting frame of AHU or with an additional of filter cabinet.4-Revision in the filter cell will not be enough alone. Fan capacity and system pressure losses should be checked. Otherwise, it is not possible to operate the AHU at the desired air flows.
- [CAN HEPA FILTER CAPTURE THE CORONAVIRUS?](https://www.ulpatek.com/products/articles/can-hepa-filter-capture-the-coronavirus/): Regarding the Coronavirus (COVID-19) epidemic, the most common question asked about filtration is that “Can HEPA Filter capture the viruses?” The answer to the question; Yes, HEPA Filters captures the viruses within their efficiency value.

- [GAS PHASE FILTRATION](https://www.ulpatek.com/products/articles/gas-phase-filtration-2/): Airborne pollution sources are various which can be from natural sources like volcanos, thermal sources, pollens, sand storms and from industrial life like factories, automobile emissions, jet fuels, garbage dumps ete. Pollutants are divided in to three physical conditions as solids, liquids and gases. Effective pollution control can be easily made by particulate and gas phase filtration. These filtration methods and applications are define at ISO16890, EN1822, ISO 10121-3. Airborne pollutants comparison chart shows size differences related particulate and gas phase filtration.In order to apply the control methods for the gas phase pollutants, we have to know the pollutants and it's effects. Main airborne pollution effects;Process control systems, data centers and other rooms that have instrumentation which has to be environmental controlled must supply G1 classification according to ISA requirements. Achieving room ventilation design requirement must supply a minimum room pressurization of 1-3 air changes per hour and recirculation of 6-12 air changes per hour. Temperature is typically 22 °C (±2 °C) with humidity lower than 50% relative humidity. Tightness of the room is also another parameter while defining the design parameters. In addition to these parameters, hazardous pollutants are main parameter which must be removed from the enclosed space. Contamination concentration levels are defined in ANSI/ISA-71.04.Monitoring for gas phase air filters is made by passive monitoring or online monitoring.
- [Top Questions On Your Mind](https://www.ulpatek.com/products/articles/top-questions-on-your-mind/): HEPA filters are designed for single use. However, there are some specially laminated HEPA filters that can be cleaned with pressurized air systems like Jet-Pulse. Aside from these, conventional HEPA filters commonly in use cannot be cleaned.The gasket type for HEPA filters shouldn't be assessed independently. The sealing surface of the housing where the HEPA filter will be installed must be fully compatible with the gasket. For instance, gel-type filters are suitable for knife-edge sealing surfaces, while PU foam or EPDM is appropriate for flat surfaces. For surfaces with a test groove, either gel or flat EPDM gasketed HEPA filters should be used. Having the filter and housing manufactured by the same producer reduces potential leakage risks.Where contaminant concentrations are not high, Ulpatek recommends a total life of up to 10 years for HEPA filters, including shelf life; for MDF-framed filters, see question 10. We've observed some Ulpatek HEPA filters in the market still functioning without issues within this period. Factors influencing the filter's service life include: the volume of outdoor and re-circulated air filtered, frequency and duration of aerosol challenge exposure, total amount of aerosol impingement on the filter, method of aerosol introduction to the system, and the efficiency of pre-filtration.For energy efficiency, the advised end-of-life differential pressure value for HEPA and ULPA filters is twice the initial pressure of the filter. Depending on the end user, this value can range between 300-600Pa.Ulpatek recommends a shelf life of up to 3 years. For filters stored beyond this period, a risk analysis should be performed before use. In any case, filters should be stored in their original packaging in a cool and dry environment away from extreme temperature and humidity conditions.Filters can be repaired to specific limits both at the factory and in the field. Recommendations for repair in the factory can be found in the following standards: IEST RP-CC001.5 IEST RP-CC034.4 ISO 29463 Additionally, ISO 14644-3 allows the customer and supplier to mutually agree upon the allowable repair size.According to ISO 29463, ULPA filters (group U, from ISO 50 U upwards) are tested individually: their efficiency is determined at the MPPS in accordance with ISO 29463-5, and they must be leak tested with the MPPS scan method of ISO 29463-4; no alternative leak test is allowed for this group. (EN 1822 class U15 corresponds to ISO 55 U.)EN 1822, ISO 29463, IEST-RP-CC001 and IEST-RP-CC034 are international standards related to air filtration, specifically focusing on high-efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) filters. These standards define the requirements and test procedures for the classification, performance, and marking of these filters at factory. ISO14644-3:2019 which Portions of the test methods have been adapted from IEST-RP-CC034.4 specifies procedures for the leakage test of installed HEPA filters.Conventional micro glass fiber has a homogeneous structure, and both of its surfaces possess identical properties, there might indeed be no specific airflow direction required for HEPA filters produce by this filtration media. However, when an additional component or surface feature, like lamination, is used the direction of airflow becomes important.HEPA filters with MDF (Medium Density Fiberboard) frames present certain concerns, especially in humid environments. The natural fibrous structure of MDF allows for the absorption of moisture, creating a conducive environment for the growth of microorganisms. Prolonged exposure to humidity can also lead to the formation of micro-cracks in the MDF structure. These cracks can directly impact filter performance, as they may hinder the proper flow of air through the filter or cause leakages. Due to these reasons, the recommended usage duration for MDF-framed HEPA filters is one year.
- [EN1822 and ISO29463: HEPA Filter Tests and Standards](https://www.ulpatek.com/products/articles/en1822-and-iso29463-hepa-filter-tests-and-standards/): EN 1822, a European standard, provides a detailed classification system for HEPA and ULPA filters based on their filtration efficiency and ability to capture particles of various sizes. Its test methods (the efficiency test and the leak test, including the scan method) have been defined in EN ISO 29463 Parts 2–5 since 2019.
- [Recommendations for Fine Dust Filtration Filters](https://www.ulpatek.com/products/articles/recommendations-for-fine-dust-filtration-filters/): Regular Inspection: Check the filter regularly for visible signs of clogging or damage. A blocked filter can hinder system performance.Final Pressure Drop: According to the EN 13053 standard, the final pressure drop is determined. ISO ePM1, ISO ePM2.5, and ISO ePM10 classes is calculated by either adding 100 Pascal (Pa) to the initial pressure drop of clean filters or by calculating a value up to three times smaller than the initial pressure drop of clean filters.
- [Eurovent Certification: Verified Performance](https://www.ulpatek.com/products/articles/eurovent-certification-a-guarantee-of-performance/): At Ulpatek, we take quality and performance seriously. Our air filters are Eurovent certified, which means that their declared performance has been verified by independent laboratory tests. Eurovent certification is a valuable asset for any HVAC system.Why Eurovent?Trust: A globally recognized seal, ensuring our filters meet strict performance standards.
- [Basic Principles of Mechanical Filtration](https://www.ulpatek.com/products/articles/basic-principles-of-mechanical-filtration/): It is the simplest filtration mechanism. It is the process of capturing particles larger than the gap between the two fiber threads used as the filter element.Particles, when encountering a filter fiber in their path, want to continue their journey without altering their parallel orientation. However, due to their inertia, they fail to do so and instead collide with the fiber and adhere to its surface.If the particle size is very small, the particle can follow an orbit around the fiber thread along with the air. However, if this orbit passes closer to the fiber than half the particle radius, the particle is captured by the fiber and adheres to it.When the particle size is smaller than 1 µm, gas molecules colliding with the particles can cause them to move erratically. As a result of this behavior, particles colliding with the filter fiber can adhere to the filter.Between charged particles and filter fibers, particles adhere to the fibers due to the principle of opposite charges attracting each other.
- [ISO 16890 Standard for Air Filters Used in General Ventilation](https://www.ulpatek.com/products/articles/iso-16890-standard-for-air-filters-used-in-general-ventilation/): ISO 16890 replaced EN 779 as the standard for general ventilation air filters in 2018; in North America, ASHRAE 52.2 (MERV) is still used. ISO 16890 measures the efficiency of an air filter in the particle size range 0.3 μm to 10 μm. The classification is carried out according to standard for particle size range 0.3-1.0 μm, 0.3-2.5 μm and 0.3-10 μm. The process is considered while choosing filters according to more detailed and global standard.A synthetic powder called ASHRAE dust is used in the efficiency test of an air filter according to EN779: 2012 standard. The test is done by loading the filter with this powder in the laboratory environment. By this way, the efficiency of the filter can be calculated in the particle size of only 0.4 μm . In operating conditions, filters are exposed to pollutants with a variety of different sized particulate. Therefore, the data obtained in the laboratory is insufficient to determine the performance of an air filter.The EN 779: 2012 standard which was used in the classification of Coarse filters, Medium Filters and Fine Filters replaced by the ISO 16890 standard. With this change in standard, filter users will are able to choose the filter much more accurate according to their needs.ISO 16890 standard considers for the particle size (Particulate Matter = PM) between 0.3 µm and 10 µm for efficiency evaluation.
- [Recommendations for Coarse Filtration Filters](https://www.ulpatek.com/products/articles/recommendations-for-coarse-filtration-filters/): Regular Inspection: Check the filter regularly for visible signs of clogging or damage. A blocked filter can hinder system performance and can be detrimental to subsequent fine filters.Final Pressure Drop: According to the EN 13053 standard, the final pressure drop is determined. ISO Coarse class is calculated by adding 50 Pascal (Pa) to the initial pressure drop of clean filters or by calculating a value up to three times smaller than the initial pressure drop of clean filters. ISO ePM1, ISO ePM2.5, and ISO ePM10 classes is calculated by either adding 100 Pascal (Pa) to the initial pressure drop of clean filters or by calculating a value up to three times smaller than the initial pressure drop of clean filters.
- [Selection of Filters According to ISO 16890 Standard in HVAC Applications](https://www.ulpatek.com/products/articles/selection-of-filters-according-to-iso-16890-standard-in-hvac-applications/): ISO 16890 standardizes the selection of air filters and gives it a scientific basis. Selecting air filters based on the ISO 16890 standard is important for improving indoor air quality and the efficiency of HVAC (Heating, Ventilation, and Air Conditioning) systems. Members of the Eurovent Association, which includes filter manufacturers playing a significant role in the Europe, Middle East, and Africa (EMEA) market, have published the document 'Eurovent REC 4/23.' This document provides recommendations for selecting filters to achieve the required indoor air quality according to ISO 16890 standards, drawing upon the work of the World Health Organization (WHO). To achieve the desired indoor air quality, the outdoor air particle concentration values have been categorized based on general ventilation and industrial usage. The required supply air (SUP) quality is obtained through recommended filtration efficiency to attain the desired indoor air quality.
- [Particle Matter](https://www.ulpatek.com/products/articles/particle-matter/): Due to increased air pollution, the effects of particulates on human health has begun to be discussed in more detail. The results show that particle matter is a serious health hazard that causes respiratory diseases and cancers. Air filters for general ventilation are widely used in buildings for heating, ventilation and air conditioning applications. Air filters increase the indoor air quality by reducing the particulate matter concentration, thereby protecting human health considerably.Particles larger than 10 μm in the atmosphere collapse very quickly and they can only hang in the air in strong wind near the source they are leaving. As an exception, some light fibers can stay in the air longer, despite their large diameter. Most particles larger than 10 μm in diameter can be seen with the naked eye in case of proper illumination and contrast. Under normal conditions, the minimum visible particle diameter is 30 μm and above.Particles ranging in diameter from 5 to 10 μm or larger are separated and trapped by the upper respiratory tract. The intermediate sizes collaps on air channels of the lungs, then swallowed or coughed. Particles ranging in diameter from 2.5 to 5 μm are likely to be retained in human lungs and are returned to the upper respiratory tract without falling into the depths of the lungs. Particles ranging in diameter from 1 to 2.5 μm are retained in the bronchi and pose risks to human health. The particles at 1 μm and below are small enough to interfere with the blood flow from the cell membranes of the alveoli.HVAC (Heating, Ventilation, and Air Conditioning) systems are fundamental to maintaining a comfortable and healthy indoor environment. However, airborne contaminants, such as particulates and particle matter (PM), can significantly hinder their performance and energy efficiency, emphasizing the need for effective filtration and maintenance.
- [Understanding Most Penetrating Particle Size (MPPS)](https://www.ulpatek.com/products/articles/understanding-most-penetrating-particle-size-mpps/): Most Penetrating Particle Size (MPPS) refers to the particle size that is most difficult to capture. The MPPS is important to consider when choosing an air filter, as it is the worst-case scenario for particle removal efficiency. For HEPA filters MPPS is generally between 0.1-0.2 microns. The standard determines efficiency based on this critical value. We can say that particles smaller or larger than MPPS are captured at higher efficiency compared to MPPS efficiency.
- [What is HEPA Filter?](https://www.ulpatek.com/products/articles/what-is-hepa-filter/): A High Efficiency Particulate Air (HEPA) filter is a type of air filter designed to remove very fine airborne particles, such as virus, bacteria, and mold spores, from the air. These filters are commonly used in various applications, including pharmaceutical cleanrooms, healthcare facilities, microelectronics, and food & beverage, to improve indoor air quality and protect sensitive equipment or processes.
- [The Total Cost of Ownership of Air Filters](https://www.ulpatek.com/products/articles/the-total-cost-of-ownership-of-air-filters/): It is essential to understand the total cost of ownership (TCO) of air filters before making any purchasing decisions. There are various factors affecting TCO, such as, energy cost, filter cost, labor, and disposal, to help you make an informed decision.Energy consumption is one of the most significant contributors to the TCO of an air filter. Higher energy consumption results in higher operating costs. Factor that affect energy consumption is the pressure drop of filter. Pressure drop is the reduction in air pressure as it passes through the filter media. A higher pressure drop means the HVAC system must work harder, increasing energy consumption and operating costs. To minimize TCO, consider filters with a lower pressure drop that allow for optimal airflow and reduced energy usage.The initial purchase price of the air filter is an essential component of TCO. High-efficiency filters may have a higher initial cost, but they often require less frequent replacement and provide better air quality, leading to long-term savings. Consider the overall lifetime value of a filter instead of focusing solely on its initial cost.The labor cost associated with filter replacement and maintenance contributes to the TCO. High-quality filters typically have a longer lifespan, reducing the frequency of replacements and labor costs. When evaluating TCO, consider the cost of hiring technicians and the time required for filter replacements.Disposing of used filters contributes to the TCO as it involves costs for transportation and waste management. Selecting filters with extended lifespans and recyclable materials can help reduce disposal costs and minimize the environmental impact.To calculate the Total Cost of Ownership, it is necessary to first calculate the energy consumption. The energy consumption formula is as follows.Under Other Costs, there are expenses related to storage, transportation, losses due to damage, and waste disposal costs.Understanding the total cost of ownership of air filters is crucial for making informed purchasing decisions. By considering factors such as pressure drop, energy cost, filter cost, labor and disposal, cleaning, you can choose the right filter for your needs while minimizing long-term expenses. Remember that investing in high-quality, energy-efficient filters can lead to significant savings and better indoor air quality in the long run.
