Not all HEPA filters are alike. The HEPA filter is the most basic filtration system for all the best HEPA air purifiers. HEPA stands for High-Efficiency Particulate Air. In short, HEPA filters capture small particles like dust, pollen, mold, smoke, pet dander, and so on very well.
What Is H13 HEPA And Medical-Grade HEPA?
There are different classes of HEPA filters, according to the EN 779 normalization standard. Classic HEPA filters are usually H10, H11, or H12 class. The best HEPA air purifiers will use H12 HEPA filters.
However, H13 is even better than standard HEPA filters. Precisely, the H13 filter captures particles that are more than 3x smaller than classic HEPA filters.
H13 HEPA filters are so thorough they are used in clinics, hospitals, and dental offices.
Can HEPA filter out germs like mold, bacteria, or viruses, including COVID-19?
Yes. It’s specifically a filter’s HEPA material that captures these particles. According to independent lab testing, Alen True HEPA filters can capture 99.9% of particles down to 0.1 microns, including aerosolized viruses. However, according to current scientific data, those trapped virus particles die or lose infectiousness within 72 hours.
True HEPA is essential if you care about improved overall wellness, better sleep, and relief from allergies and asthma.
