In this article, we describe the HEPA filter in detail, such as its definition, structure, types, benefits, and applications. We also focus on the advantages of HEPA H13 filters and the differences between H13 and H14 filters.
HEPA stands for High Efficiency Particulate Arresting or Air Filtration. It also means that air filters need to meet the specified standards of HEPA to be HEPA filters. HEPA filters were first put into use during World War II, but the demand for HEPA filters has skyrocketed in recent years due to the outbreak of COVID-19. More and more people are interested in HEPA filters.
HEPA Filter is usually made of pleated glass fibers as filter material, and the outer frame is usually made of stainless steel, extruded aluminum, wood, galvanized sheet metal, ABS, and so on.
HEPA filters can be divided into Mini pleat HEPA Filters, separator HEPA Filters, V Bank HEPA Filters, Box Type HEPA filters, and Compact HEPA filters according to their shape.
Definition according to DIN EN 1822-1:2009
EPA filter (Efficient Particulate Air Filter)

ULPA filter (Ultra Low Penetration Air Filter)
HEPA filters are essential for maintaining indoor air quality, maintaining a healthy living environment, and protecting human health.
1. Improve indoor air quality: In a closed indoor environment, air quality seriously affects human health, HEPA filters can effectively remove formaldehyde and other harmful pollutants in household products, thus improving indoor air quality.
2. Ensure the cleanliness of the air in a specific environment: The medical, pharmaceutical, microelectronics, and other industries have very high requirements for indoor air quality. Airborne particles can pose a serious threat to product quality, production process, and human health, therefore, HEPA Filter has become one of the indispensable cleanroom equipment in these fields.
3. Prevent the spread of disease: Many viruses and bacteria can be spread through the air, HEPA filters can effectively filter out these microorganisms, thus reducing their spread and the chance of infectious diseases.
4. Protect human health: airborne pollen, mold, viruses, bacteria, and other allergens may cause respiratory illness or allergic reactions and other disease problems. HEPA filters can capture these pollutants and reduce the concentration of air pollution, thus protecting people's respiratory systems and physical health.
A HEPA Filter captures airborne particles as they pass through a fine fiber mesh. This mesh is usually made of glass fibers, with fibers of different sizes interwoven into a dense mat. Air does not flow directly through the filter; instead, it passes through a complex mesh to capture contaminants.
The HEPA Filter removes more than 99.97% of the 0.3 microns (μm) size particles in the air. Viruses are spread through the air by attaching to tiny particles such as droplets, aerosols, or dust, and the HEPA Filter effectively intercepts these particles, thereby reducing the number of carriers for the virus and thus reducing the spread of the virus.
HEPA H13 Filter and H14 Filter are both known as medical-grade air filters. They are commonly used in medical environments.
1. High filtration efficiency: H13 and H14 filters have extremely high filtration efficiency and can usually capture more than 99.97% of 0.3μm size particles in the air. This keeps the air clean.
2. Long service life: H13 Filter and H14 Filter are durable and have a long service life. Generally can be maintained for 12-18 months, depending on the conditions of use, a longer service life can reduce costs.
3. Improve indoor air quality: H13 Filter and H14 Filter have strong air pollutant removal ability, which is especially beneficial for asthma and allergy sufferers.
1. Medical facilities: to create a sterile environment free of airborne contaminants
2. Living spaces: to improve indoor air quality
3. Commercial environments: to keep the air clean in offices, beauty salons, etc.
4. Industrial environments: an indispensable part of cleanrooms in microelectronics, aerospace, and other manufacturing industries.
High efficiency HEPA filter h13 and high efficiency HEPA filter h14 are both known as medical-grade air filters, but there are big differences between the two.
1. The H13 HEPA Filter is the best choice for balancing the airflow of the high efficiency filter box because of its lower density of components, which allows the air to flow freely. While the H14 Filter has a higher density and high filtration level, so H14 Filter can be used in the case of small pollutants in the air.
2. The H13 Filter is less tightly woven, so the air can easily pass through the filter, so less leakage occurs, on the contrary, the H14 Filter itself is very tight, so the air penetration is smaller, and leakage is very easy to occur.
H13 HEPA Filter has a huge role to play in improving indoor air quality.
1. Removal of allergens: H13 HEPA Filter can effectively remove pollen, pet dander, and other allergic particles in the air to protect human health.
2. Disease control: H13 HEPA Filter can effectively prevent the spread of viruses.
3. Odor Reduction: H13 HEPA Filter can be used in conjunction with activated carbon filters to reduce odors in the air.
The HEPA Filter is especially suited for environments that require strict air quality control, such as hospitals, cleanrooms, pharmaceutical processes, and healthcare facilities. In these environments, HEPA Filters can significantly reduce the concentration of airborne viruses and protect personnel from infection.
To extend the life of the H13 HEPA Filter, regular maintenance of the H13 HEPA Filter is required.
1. Check the filter for contamination and damage every six months
2. Replacement schedule: Usually the service life of an H13 HEPA Filter is 1-3 years, please check with the supplier for the usage time of the filter.
3. Regular cleaning: The H13 HEPA Filter is usually not washable, use a soft brush to remove the dust and other pollutants attached to the surface.
What is the difference between the H11 and H13 HEPA Filters?
The H11 HEPA Filter filters at least 95% of airborne particles with a diameter of 0.1 microns, while the H13 HEPA Filter captures at least 99.95% of the same size particles.
Can you clean a HEPA Air Filter?
Generally, HEPA filters are not washable as this will damage the surface structure of the HEPA filter. If you need a washable filter, please talk to your supplier about purchasing a HEPA filter that is made of a washable material.
What is the difference between True HEPA and H13 HEPA filters?
The True HEPA Filter captures 99.97% of particles down to 0.3 microns in diameter, while the H13 HEPA Filter follows the more stringent European standards and captures 99.95% of particles down to 0.1 microns.
What is the difference between a HEPA filter and a conventional filter?
Ordinary filters capture larger particles of airborne contaminants than HEPA filtration, so choose a HEPA filter for environments that require higher levels of air cleanliness.
How long does a HEPA filter last?
The life span of a HEPA Filter is usually 1 to 3 years, consult the HEPA Filter manufacturer for details.
Do HEPA air filters work?
Yes, the HEPA Filter's excellent filtration efficiency makes it an indispensable part of medical, home, and other environments.
