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). A HEPA filter is an air filter for fibrosis that is normally made of plastic fibers (polypropylene), fiberglass, or borosilicate glass fibers. These fibers are bonded close together (often with a 5% acrylic binder) to prevent certain particles from passing through. True HEPA filters are a bit more advanced, since they capture up to 99.97% of particles that measure just 0.3 microns from the air. These particles can be bacteria, viruses, pollen, mold, dandruff, or other microorganisms.
True HEPA is mainly composed of very dense paper, which can be made of very fine fibers with distances between 0.3 and 2.0 microns. This allows the filter to capture a wide range of fine particles in the air, of small, medium and large sizes. In addition, the high-density paper used as the pleated filter material for the HEPA filter is usually housed in a metal or plastic frame with a seal that prevents air particles from escaping what the True HEPA has trapped during the filtration process. You can effectively remove dust, pet dander, pollen, bacteria, viruses, and other pollutants from the air with a durable, waterproof True HEPA filter. It is always recommended to replace the HEPA filter with a new one when it loses efficiency.
HEPA filters work great for capturing dust, pollen, pet dander, and other particles that are 0.3 microns or larger. True HEPA filters are also very effective and can trap up to 99.97% of particles no smaller than 0.3 microns. Each HEPA filter is made up of thousands of glass fibers intertwined to form a labyrinth capable of stopping microscopic particles. HEPA filters are the most commonly used filtration technology in both commercial and residential environments. Leveraging ionization technology allows you to capture more debris in the air so that the HEPA filter can do its job more efficiently. Normal HEPA filter air purifiers are the least recommended, since particles that are 1.99 microns or smaller are not removed.
The carbon prefilter also captures smoke, odors, harmful gases, and volatile organic compounds (VOCs), which HEPA filters cannot trap. When looking for portable air purifier solutions for your installations, it's essential to know the difference between HEPA filters, true HEPA filters, HEPA-type filters, and other types of HEPA filters. HEPA-type filters, which are sometimes also referred to as HEPA type or HEPA type, do not meet the DOE HEPA standard. According to the DOE definition, HEPA filters can capture up to 99.97% of airborne particles with a size of 0.3 microns (µm), also known as the most penetrating particle size (MPPS).However, although they have been scientifically proven to remove pollutants from the air, classic HEPA filters are the least efficient of the three.
HEPA filters
get this name because of their ability to capture fine particles larger than 0.3 microns on their inner surface, and this can include all particles that can reach the lungs, with 0.3 microns being the smallest particle that enters human lungs. Depending on the size of the particle, the HEPA filter will trap contaminants in a complex network of fibers.These considerations about HEPA filters are essential when your goal is to reduce viral transmission by aerosol.
