A true HEPA filter, an acronym for High Efficiency Particulate Air, is considered the ultimate filter due to its exceptional performance. The filter was initially developed during World War II by the Atomic Energy Commission for the protection of researchers working with radioactive dust particles, which could pose a significant health risk. It exhibits an impressive efficiency rating of 99.97%, proficiently capturing particles as minuscule as 0.3 microns. Its effectiveness and high filtration capability make it the preferred choice for various applications requiring superior air purification.
The HEPA filter is widely used in household vacuum cleaners, purifiers, and medical purifiers due to its ability to allow air passage while blocking fine particles. It is highly effective in filtering out dust mites, bacteria, and other pollutants, reaching an impressive 99.7% effective rate for particles measuring 0.1 μm and 0.3 μm. High-level HEPA filters are even employed in medical cleanrooms to achieve a Dust-free standard by eliminating harmful substances and bacteria. This versatile filter medium has proven to be a valuable asset in maintaining clean and healthy environments.

What is HEPA Means?
HEPA stands for High Efficiency Particulate Air, and a true HEPA filter is widely regarded as the ultimate filter. It was invented during World War II, when the Atomic Energy Commission needed a filter to protect researchers from radioactive dust particles that might present a health hazard to them. It traps particles as tiny as 0.3 microns with an efficiency rating of 99.97%.
The European Standards About Vacuum Filtration Classes (L/M/H CLASS)
The three classes are ‘L’, ‘M’ and ‘H’ (Low, Medium and High Hazard).
● Class ‘L’ – Dust represents a moderate risk to the operators – The vacuum’s filters trap over 99% of the dust with a grain size of under 2 microns
● Class ‘M’ – Dust represents a medium risk to the operators – The vacuum’s filters trap over 99.9% of the dust with a grain size of under 2 microns
● Class ‘H’ – Dust represents a high risk to the operators – The vacuum’s filter traps over 99.995% of dust with a grain size of under 1 micron which includes carcinogenic dusts and dusts contaminated with pathogens.
What’s the Function of HEPA?
For 0.1 μ m and 0.3 μ m, the effective rate reaches 99.7%. The HEPA filter is characterized by that air can pass through, but fine particles cannot. HEPA filter screen is generally applicable to household vacuum cleaners, purifiers and medical purifiers. It is the most effective filter medium for dust mites, bacteria and other pollutants. In the medical clean room, high-level HEPA filters can be used to filter out harmful substances and bacteria, reaching the dust-free standard. In many worldwide famous brands of vacuum cleaner, they adopts high-level HEPA filter from our factory(PURO Purification), which can effectively filter out dust mites in the home, purify the air and improve the living environment at home.
HEPA’s Advantages?
HEPA filter is also used in the internal structure filter element of many vacuum cleaners because of its large effective filtering area, small volume, low resistance and even air flow. Vacuum cleaners are now widely used in families. Why do they have such a high purchase rate and are recognized by everyone? Because the vacuum cleaner has high filtration efficiency and can adsorb and filter out the particles and dust discharged by small spiders that cause allergic and asthmatic symptoms, the HEPA filter is effective in the vacuum cleaner. When designing the vacuum cleaner, all air should be sucked into the machine and filtered through the HEPA filter screen to discharge harmful gas and dust. We (PURO Purification) can supply such kind of HEPA.
The Material of HEPA？
High efficiency filters are made of PP filter paper, glass fiber, composite PP pet filter paper, melt blown polyester non-woven fabric and melt blown glass fiber. We (PURO Purification) can supply any kind of material according to your specification and demands.
How Do HEPA Filters Work?
There are different types of HEPA filters, but True HEPAs filter by mechanical air filter method. Air is forced through a fine mesh, which can trap particles of 0.3 µm in size.
HEPA filters are made by randomly arranging the polypropylene or fiberglass fibers (between 0.5 and 2.0 µm). While sometimes the fibers are arranged in a tangle, the fibers can pass air through and trap some of the particles. The important part is that the fibers create narrow pathways for the air to pass through. Larger particles are trapped because they can’t keep up with the constant movement and maneuver through the fibers. But some smaller particles have very little inertia and can pass through with the air and along with the twists and turns of the fiber mesh...
Types of HEPA Filters
There are different types of HEPA filters.
● True HEPA: At its highest efficiency, it should remove 99.97 percent of all particles that are 0.3 microns in size. Only the label True HEPA (and sometimes Absolute HEPA) has any real meaning because it is the only one to claim to adhere to a standard.
● Absolute HEPA: Sometimes means the same thing as True HEPA, but it claims a higher filtration power (up to 99.999 percent at 0.3 microns).
● Ultra HEPA: Some brands used Ultra HEPA, claiming that their product is “100x more effective than HEPA air filters,” able to remove particles down to 0.003 microns in size. This is technically impossible and may be misleading marketing.
● Permanent HEPA: Permanent filters are marketed as meeting the HEPA rating but can also be washed and reused rather than replaced. It is not recommended that you wash HEPA filters because the washing process can reduce effectiveness over time.

Can HEPA Wash By Water?
Washable or permanent HEPA filters are easy to maintain and can drastically cut the cost of replacement filters. If your air purifier or vacuum cleaner uses a HEPA filter, you should check its product manual before attempting to clean the filter. A washable HEPA filter should be rinsed with water at least monthly, while getting a non-washable permanent filter wet will ruin it. Rinse your washable filter until water runs through it clearly, then let it dry completely before reinstalling it. Use a vacuum cleaner hose with a brush attachment to remove contaminants from a non-washable filter...

Which Is Better, Carbon or HEPA Filters?
Both HEPA filters and carbon filters do things that each other can’t. HEPA filters are better at removing bigger, physical particles like pollen, dust mites, mold, and other allergens. Carbon filters are better at removing odors, smoke, and other gaseous particles. Fortunately, quite a few brands of air purifiers employ both HEPA and carbon filters, but they can be a bit more expensive. So please choose the one suitable. We (PURO Purification) supply HEPA for vacuum cleaners.
How HEPA to be Made？
The glass fibers that make up a HEPA filter are created by passing molten glass or plastic through very fine pores in a spinning nozzle. The resulting glass fibers cool and harden almost instantly because of their tiny diameters.

What is the Difference Between HEPA Filter and Ordinary Filter? Which is better?
Benefit of HEPA Filters
HEPA filters offer the following related benefits:
· Fewer airborne particles and less dust in your home
· Better indoor air quality
· Fewer problems with allergies and asthma
For families with asthma and allergy problems, these benefits easily outweigh the potential cost.
Traditional Air Cleaners
Traditional air filters, except for those at the low end of efficiency ratings, also filter small particles out of the air. While they won’t remove as high as percentage of airborne particulates as HEPA filters, higher-efficiency standard air filters can still greatly improve indoor air quality while protecting your HVAC equipment.
All in all, choose the suitable filter. If you need HEPA filter, you may contact us at: wade.xue@purofiltration.com or make a phone call at: 86-181 3695 6775. Please visit us at: www.purotechs.com first.
Difference Between HEPA Filter and ULPA Filter
Both filters use layers of dense fibers to create a fine mesh filter that removes contaminants as air is forced through them. Both HEPA and ULPA filters use a combination of three main methods to trap contaminants: diffusion, interception, and inertial impaction.
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. HEPA filters can be combined with pre filters to trap larger particles before they come into contact with the main filter.
The higher efficiency rating of the ULPA filter is due to the increased density of the filter medium, which allows airflow up to 50% lower than HEPA filters and requires more power to move air. HEPA filters have a lifespan of up to ten years, whereas the typical life cycle of an ULPA filter ranges from five to eight years. Choosing the right filter for your application depends on containment regulations and standards in your facility. We (PURO Purification) would like to give you some hints if you are not clearly know which one you prefer.
How to Choose a Good(suitable) HEPA Filter Manufacturer and What Should be Considered?
Determining the best filter for your application requires a careful analysis of your needs and any containment regulations for your facility.
HEPA and ULPA filters are designed for use in a variety of applications, including industrial vacuum cleaners to remove asbestos, removing toner dust from office equipment, preventing the spread of airborne bacteria in surgical operating rooms, and other crucial medical air filtration applications.
Understanding the requirements of your application and the level of effectiveness needed will help you choose the right filter for your needs.
Assembly
There are very few components in an air purifier. For this reason, they are usually bench assembled. In bench assembly, moving conveyors bring the individual components or sub-assemblies (e.g., the fan already attached to the case) to a bench where a person then hand assembles them. In a typical HEPA air purifier, there may only be five components that require assembly: casing, fan, particulate filter, carbon filter, and the on/off switch.
