What is HEPA Filter
HEPA is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. of Energy). It's an air filter efficiency standard that's used to certify a filter's performance. A HEPA filter is that it is made of thin fibers of glass and activated carbon-based materials, while regular filters are made of porous materials like cotton paper sheets and polyester. HEPA filters are designed to trap small, harmful particles, such as: Pollen, Pet dander, Smoke, Dust mites, Bacteria, Mold. The filters work by forcing air through a fine mesh, in theory, HEPA filters can remove at least 99.97% of airborne particles that are 0.3 microns in diameter.
Features of HEPA Filter
Efficient Running
CARB, ETL, ISO, UL certified, HEPA filters capture up to 99.99% of fine particles as small as 0.1 microns, including allergens, smoke, mold, pollen, dust and odors and other fine particles you don't want to inhale.
Wide Application
Our HEPA filter is made of non-woven fabric and fiberglass materials. It adopts a lower density structure and can firmly absorb dust and mold in the air, which is suitable for all kinds of pets, smokers, and families with open kitchens.
Quick Cleaning
When paired with a smart particle sensor, the HEPA filter can adjust when contaminated air is detected, cleaning large rooms up to 1,115 square feet in just 60 minutes.
Easy to Install
We recommend that you replace the HEPA filter every 12 months, and it is very simple to install and remove without any tools, just remove it from the machine unit and replace it.
Application of HEPA Filter
Biosafety Cabinet
Biosafety cabinets are designed for the protection of workers who work with hazardous materials. They have a vertical laminar airflow that creates a barrier for airborne particles and microorganisms. HEPA filters are used to clean air returning to the work area and out into the environment.
There are three levels of Biosafety cabinets: Classes I, II, and III. Classes II and III offer protection for workers, the environment, and products. Class I cabinets are very basic and protect the environment and personnel. When implemented properly, biosafety cabinets effectively reduce contamination, diseases, and the spread of harmful materials.
Clean Rooms
The working conditions that require the most enhanced methods of contamination removal are cleanrooms, which work with a wide variety of substances, products, and materials that can be potentially damaged by unfiltered and unclean air. The term clean room covers a wide array of work areas constructed and designed to create a perfect and ideal set of working conditions.
Grades of cleanrooms are dependent on the number and sizes of particulate matter in the room. The smaller the number of particles and the fewer per cubic foot, the higher is the classification of a clean room. An essential part of ensuring the proper environment is the filtration system, which relies on the performance of HEPA filters that are placed in the ceiling, walls, or cabinets.
HEPA Filters in Hospitals
As with clean rooms, HEPA filters are a necessity for hospitals to prevent cross contamination between patients and the spread of infectious and dangerous diseases. In the age of COVID-19, HEPA filters have become an essential part of preventing the spread of the disease and protecting hospital personnel and patients.
●Surgical Suites
It is very critical that the air in an operating room be filtered and kept clean and clear. HEPA filters are used to remove airborne contaminants that could be of danger to patients when their organs are exposed during medical procedures.
●Incubators
Newborns are susceptible to a wide range of diseases due to their weak immune system. HEPA filters remove bacteria, viruses, and infectious materials from the air in incubators and are especially important in neonatal intensive care units. They ensure that the air flow is free and clear of microbes.
●Warming Beds
Warming beds are used in closed circuit forced air systems to keep patients at a controlled temperature. HEPA filters are used in forced air systems to capture and contain dangerous particulate matter and keep them from a patient’s bed.
●Laboratories
Laboratories function much like a clean room and deal with dangerous pathogens. HEPA filters for such conditions are required by law and are specifically designed to remove microbes, pathogens, and contaminants to prevent them from spreading outside the testing environment.
Classification of HEPA Filter
In Europe
The primary standard is EN1822. They use the MPPS (most penetrating particle size) to measure air filter efficiency. Under this standard there are classes of HEPA filter ratings
●E11 - 95% efficiency at MPPS
●E12 - 99.5% efficiency at MPPS
●H13 – 99.95% efficiency at MPPS
●H14 – 99.995% efficiency at MPPS
In the US
The most common standard is the MERV Rating (Minimum Efficiency Rating Value) which is set by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers).
●MERV 16 – 95% or more efficiency at 0.3 microns and larger
●MERV 17 – 99.97% efficiency at 0.3 microns and larger
Note: **Technically MERV 16 is the highest level of filtration as defined in the ASHRAE standards. MERV 17 is sometimes used as a way differentiate a HEPA filter although is not part of their standards.
The key difference in these standards is the particle size where the efficiency is measured. In the US, filter efficiency is measured at 0.3 microns whereas in Europe it will likely be in the 0.04 to 0.17 micron range. When you go smaller than these particle sizes, filter efficiency usually increases. So, if you see a product marketed as having a certain efficiency at a particle size smaller than this, it is marketing hype.

Components of HEPA Filter
1. Filter Fibers
HEPA filters are made from polyester, polypropylene, or fiberglass fibers that are tightly interlaced with diameters of less than one micron. The fibers are twisted, turned, scattered, and randomly placed in different directions to create a mesh maze without a straight true path. The openings between the fibers are smaller than a half micron, which is why HEPA filters can catch particles smaller than 0.3 microns. The image below is taken from a microscopic examination of the fibers of a HEPA filter. What can be clearly seen is the lack of uniformity in the placement of the fibers.
2. HEPA Filter Frame
The frame of a HEPA filter can be made from a variety of materials. For ones being used for industrial and manufacturing operations, the frames are normally made of tough, resilient, and durable materials such as carbon steel, aluminum, stainless steel, or galvanized steel. The size of the frame has to be carefully planned since its resistance to the airstream can increase the pressure drop.
3. Adhesives for Filters
The selection of the proper adhesive for the making of a HEPA filter includes ones that are safe to use and will not interfere with the function of the filter. For the longevity of the filter, they must remain in place and not wick up into the fiber material. The three most common types of adhesives used to make HEPA filters are polyurethane, silicone, and ceramic.
Polyurethane is widely used in constructing HEPA filters since it is perfectly suited for the filtering process. It can be used to securely hold the fiber material in a metal frame and cures at room temperature or can have heat accelerated curing.
Silicone adhesives have flexibility and temperature resistance and come in different hardness, transparency, and viscosities. They are resistant to shock, vibrations, heat, and corrosion and can serve as electrical insulation.
Ceramic adhesives create a tight bond between the filter material and stainless steel or aluminum frames. It is perfect for HEPA filters and can bond a variety of internal components to the filter.
4. HEPA Filter Gasket
Gaskets play a critical role in the performance of a HEPA filter and can be made from die cut urethane rubber and closed cell sponge rubber. The choice of rubber as a gasketing material is more economical and easier to install than liquid silicone systems.
The material is free of mold release by splitting or skiving the top layer. To ensure the proper shape, gaskets are die cut from sheets or rolls.
Typical gasket shapes are strip, one piece, and interlocking designs. Of the three, interlocking is the most cost effective and easy to install. Gaskets are connected to the frame using solvent activated or pressure sensitive adhesives. Joints in the gasket are sealed with RTV materials that are compatible with closed cell rubbers.
The most widely used type of gasket is die cut, which is attached to the outer edge of the frame and pressed against its flat surface. All HEPA filter gaskets are oil and ozone resistant.
5. Separators in Filters
In HEPA filters, separators are placed between the pleats or folds in the filter material. They are made of aluminum, glass fiber strings, or hotmelt. Separators open the pleats in the filtering material to allow for greater particulate matter capturing and less resistance to airflow.
Factors to Consider When Choose HEPA Filter
Now that you understand what a HEPA filter is and how it works, let's explore some of the key considerations to keep in mind when selecting the best HEPA filter air purifier for your specific needs:
1
Room Size: The size of the room or space you want to purify should dictate the capacity of the air purifier you choose. Most air purifiers indicate their recommended room size in square feet, so be sure to match it with your needs for optimal performance.
2
Noise Level: Some air purifiers can be quite noisy, which might be disruptive in bedrooms or quiet spaces. Look for models with adjustable fan speeds or a "quiet mode" if noise is a concern for you.
3
Filtration Stages: While HEPA filters are incredibly effective, some air purifiers also incorporate additional filtration stages, such as activated carbon filters for odor removal or UV-C technology for germ and bacteria elimination. Consider whether you have specific concerns beyond particle filtration.
4
Filter Replacement: Regular maintenance is essential to ensure your air filter continues to work effectively. Check the cost and availability of replacement HEPA filters for the model you're considering. Some filters need to be replaced more frequently than others, so factor this into your long-term costs.
5
Energy Efficiency: Air purifiers can run continuously, so it's wise to choose an energy-efficient model to keep operating costs down. Look for ENERGY STAR certified air purifiers that meet energy efficiency standards.
6
Allergen Specificity: Some purifiers are designed with a focus on specific allergens or pollutants, such as pet dander or smoke. The best air purifier for allergies will target these and remove them before they reach you.
7
Features and Control: Some air purifiers come with remote controls, smartphone apps or voice-activated features. Make sure the controls align with your preferences.

FAQ
Q: What is the purpose of a HEPA filter?
A: It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm).
Q: How is a HEPA filter different than regular filters?
A: The main difference between a HEPA filter is that it is made of thin fibers of glass and activated carbon-based materials. Regular filters are made of porous materials like cotton paper sheets and polyester.
Q: What are the two disadvantages of HEPA filters?
A: HEPA filters are limited to particulates. There are harmful gases and fumes that may just pass through a HEPA filter. HEPA filters may cause air to become too dry. Finally, some HEPA filters may produce ozone, which is an unhealthy gas that can irritate the lungs.
Q: Is HEPA filter good for health?
A: One study cited a number of reports that HEPA air purifiers can benefit people with varied allergies by reducing the concentration of indoor allergens, including pollen, house dust-mite (HDM) allergens, and dog dander. But not all research agrees, especially when it comes to dust mites and animal dander.
Q: Who needs a HEPA filter?
A: Pretty much anyone can benefit from running a HEPA filter. But smokers, people with allergies, and anyone with an advanced airway disease such as asthma or chronic obstructive pulmonary disease (COPD) will reap the biggest rewards because they're particularly sensitive to air pollutants, Dr. Schachter says.
Q: Is HEPA filter washable?
A: Washing may make a standard HEPA filter unusable, so don't wash a filter unless the manufacturer recommends it! Some filter types are washable, you can consult it with the manufacturer.
Q: What filter is better than HEPA?
A: ULPA filters trap more and smaller particulate matter than HEPA filters. ULPA filters are 99.999% effective at removing submicron particulate matter of 0.12-micron diameter or larger, while HEPA filters are 99.97% effective for eliminating particulate matter of 0.3-micron diameter or larger.
Q: Which is better HEPA or non HEPA filter?
A: Effectiveness: HEPA filters are much more effective at removing small particles from the air than non-HEPA filters. If you're looking to improve the air quality in your home or office, a HEPA filter is likely the way to go. Cost: HEPA filters may be more expensive to purchase and replace than non-HEPA filters.
Q: Is HEPA filter better than air purifier?
A: For air cleaning performance, HEPA filter based media is the best technology. They remove the most airborne contaminants as well as the most dangerous particulates.
Q: How do I know if a filter is HEPA?
A: In order to qualify as a true, certified HEPA filter it must pass be able to have a rating equivalent to a MERV 17 or higher. This means the filter can capture 99.97% of all particles 0.3 microns or larger.
Q: What is HEPA filter made of?
A: A HEPA filter is a fibrosis air filter typically made of plastic fibers (polypropylene), fiberglass, or borosilicate glass fibers. These fibers are bound closely together (often using a 5% acrylic binder) to restrict certain particles from getting through.
Q: How many types of HEPA filters are there?
A: According to the Institute of Environmental Science and Technology, (IEST) with regard to performance, there are 6 types – A, B, C, D, E & F. Each has its own distinct characteristics as shown by chart 1 below.
Q: Can I vacuum a HEPA filter?
A: You cannot clean a HEPA filter by using something like a vacuum because the particles are trapped not only on the surface of the filter but also deep inside the media. Don't even think about running it under your sink, either—liquids like water and soap will destroy the filter media, he adds.
Q: How long do HEPA filters last?
A: Although it depends on the specific filter you have, as a rule of thumb, replaceable HEPA filters should be replaced every 6-12 months, depending on air quality and environmental factors. Carbon pre-filters should be replaced every 3 months, depending on air quality and environmental factors.
Q: Can I use a HEPA filter in my AC?
A: The air flow would be too restricted. An air conditioner or ventilation system is designed for only low efficiency filters to filter out the large dust particles to protect the equipment and not for your health which are the smaller particles.
Q: Should I sleep with a HEPA filter?
A: Studies suggest that air purifiers that contain HEPA filters. View Source are effective at reducing some symptoms of allergies and asthma. High-Efficiency Particulate Air (HEPA) filters trap allergens and particulates in the air, making it less likely that they'll be inhaled during sleep.
Q: What do HEPA filters not remove?
A: Unfortunately, HEPA filters will not remove pollutants from the air that are smaller than 0.3 microns, including viruses, some bacteria, and volatile organic compounds (VOCs). VOCs are household items like hairspray and ammonia that are too small for a HEPA filter to eliminate.
Q: Why are HEPA filters rarely used in homes?
A: Part of the reason that HEPA filters are so rarely used in HVAC systems is that they are extremely restrictive in terms of airflow.
Q: Do HEPA filters remove silica?
A: As we learned above, the dangerous portion of silica dust is the fine particles that can pass into the respiratory system. Source control of the dust at the tool is important, but only a true HEPA air filter can remove the remainder of fine silica particles from the air.
Q: What happens when a HEPA filter is dirty?
A: HEPA filters remove fine particles like smoke or pollen and mold fragments from the air, but like any filter they are eventually full of debris. As the filter fibers get clogged, the purifier will lose airflow and fewer particles will be captured.
