$226.80
HEPA filter is a 24x24x12 high efficiency particulate air filter. This air filter can remove at least 99.97% of airborne particles 0.3 micrometers in diameter. Particles of this size are the most difficult to filter and thus the most penetrating particle size. Particles that are larger or smaller are filtered with even higher efficiency. HEPA filters are the most effective air filtration filters to remove contaminants from the air.
