True HEPA filters are effective at removing ultra fine particles (think: dust, dander, pollen, mold and other common allergens in the home). The industry standard is that the unit must be able to remove at least 99.97% of particulates measuring 0.3 micron diameter in a lab setting.

What is a allergen filter?

Air filters for allergies are designed to block much smaller particles, so your air stays cleaner. They are called “high energy particulate air filters” or more commonly, HEPA filters.

Can HEPA filter trap viruses?

Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19, so the answer is yes.

What is HEPA filter material?
