What Does a HEPA Filter Purify the Air From?

In theory, this type of air filter can remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particulate matter with a size of 0.3 microns (µm). The diameter specification of 0.3 microns corresponds to the worst case scenario; the most penetrating particle size (MPPS).

HEPA filters

work well on their own and are effective at removing particles such as airborne pet dander, pollen, smoke, and dust. Air purifiers absorb air, pass it through a series of filters (including the HEPA filter), and release clean air into the room.

The filter is composed of a mesh of randomly placed fibers, which are usually layers of cellulose, synthetic fiber or glass fibers. These fibers are arranged in the shape of an accordion, which gives them a greater capacity to capture particles. The HEPA filter easily removes pathogens larger than 0.3 microns. It is currently not possible to achieve 100% filtration, although this technology is very close to achieving it, since a HEPA filter retains 99.9% of the most penetrating particles (MPPS) from 0.12 to 0.25 microns.

A HEPA filter is capable of doing this with the smallest and most penetrating particle size (MPPS), now imagine how effective they are against particles larger than one micron, which are those particles to which viruses are usually attached. They are even easier to filter and retain with the HEPA filter. Therefore, the efficiency of a HEPA filter is almost 100%. The True HEPA filter (American classification) is the one used by WINIX in our air purifiers, it is between H13 and H14 (European classification), filtering 99.97% of the particles. Diffusion works on the smallest particles.

Viscous fluid (air) does not hold small particles in place and they diffuse into the flow stream. This means that the smaller a particle is, the more likely it is to pass through the flow stream, so it is more likely to collide with the fiber and be picked up. I highly recommend the WINIX air purifier; especially if there are small children nearby. The machine is very light (very easy to move) and very easy to use.

I give five stars for its quality-price ratio. Hoogoorddreef 125 1101BB Amsterdam The Netherlands (Europe). When choosing an air purifier for your home or office, the element to consider is clearly the HEPA filter. When you buy a HEPA air purifier, you might come across terms like “HEPA type” or “HEPA style”.

The quality of the HEPA filter used by the air purifier is key, as it is the most important element in the filtration process, cleaning the air of particles harmful to health and releasing clean air. HEPA filters are pleated mechanical air filters that have a considerable thickness to capture particles. A HEPA air purifier can provide the necessary relief for allergies and respiratory tract when used correctly and chosen correctly. Today, HEPA air purifiers are a highly effective way to improve indoor air quality, reduce odors, and prevent the spread of viruses and bacteria. HEPA H13 and True HEPA filters are the most used filters today for homes, schools and offices, as they allow effective filtration and are affordable.

Air Oasis offers high-quality air purifiers that solve a number of common air quality problems. However, there are a lot of misconceptions about the HEPA standard, about whether a purifier or air filter actually meets the HEPA standard and what a HEPA filter can and cannot do. While HEPA filters remove most particulate matter from the air, there are many harmful pollutants in the air that are not particulates. All ISO-Air models come equipped with a HEPA filter, as well as two additional levels of air purification technology, including ozone-free bipolar ionization and UVC germicide.

HEPA technology is now available to the average consumer so that everyone has access to clean, healthy air. In the U. S. In the US, to be considered a true HEPA filter, a HEPA filter must be certified to remove 99.97% of all microscopic particles as small as 0.3 microns in size. A high-efficiency particulate air filter (HEPA) can remove 99.97% to 99.99% of airborne particulate matter that is 0.3 microns in size equal to or greater than 0.3 microns (EPA).
