HEPA is a type of pleated mechanical air filter. 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). The diameter specification of 0.3 microns responds to the worst case; the most penetrating particle size (MPPS). Particles that are larger or smaller are trapped with even higher efficiency. Using the worst case particle size results in the worst case efficiency rating (i.e. 99.97% or better for all particle sizes).So if HEPA filters were invented in the 1940s, and they're nothing fancy, then what makes any old filter a HEPA filter? Turns out using the term "HEPA" has a strict set of requirements. In Europe, HEPA filters must remove 99.95% (ISO) of particles. In the US,they must remove 99.97% of particles.
All air cleaners require periodic cleaning and filter replacement to function properly. Follow manufacturer's recommendations on maintenance and replacement.
How does it working
These filters are built with advanced filtration technology. The filter is made of fibers. These filters are placed in the air purification system in a manner that removes smaller particles from the pre-filters. With the help of deep filtering technology, airborne particles are captured through HEPA filters.
These airborne particles are captured by 3 different methods:
* Interception
* Impact
* Diffusion
These methods ensure that the filter in the purifier is working at its full strength and unwanted particles are at bay
