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.
Do HEPA filters remove pollen?
According to the Environmental Protection Agency (EPA), HEPA filters can theoretically remove up to 99.97% of dust, pollen and any airborne particles with a size of 0.3 microns, so they should safely take care of pet dander floating in the air.
When used properly, air cleaners and HVAC filters can help reduce airborne contaminants including viruses in a building or small space. By itself, air cleaning or filtration is not enough to protect people from COVID-19. … Others indicate they use High Efficiency Particulate Air (HEPA) filters.

What is HEPA filter material?
HEPA filters are high efficiency filters that typically capture over 99.5% of all particulate pollution. They’re made from either plastic (PP+PET) or fiberglass, and can capture things like pollen, viruses, bacteria, mold and PM2. 5. Diffusion also means they are highly effective at capturing nanoparticles too.
Is HEPA filter washable?
If the filter is marketed as being washable or permanent, then it is possible that you can wash it or clean it off and it will still function. However, there is no standard for washable HEPA filters, and there have not been studies testing how well these filters work after they have been washed.
What air purifier is best for asthma?
HEPA air purifiers are typically considered the best option for those with asthma, but your healthcare provider will help you make the final decision. In general, HEPA filters are popular because they can capture particles as small as 0.3 microns, cleaning the air of 99.7% of allergens that pass through it.
Do HEPA filters help with dust mites?

But if a HEPA system is run over a period of time, it can take out a big chunk of viruses — somewhere in the high ninetieth percentile (99.94 to 99.97%). And long enough exposure to the UV light in an air purifying device can disable some viruses, including COVID-19.
Do HEPA filters remove formaldehyde?
HEPA filters will do a great job of capturing particles, but not the VOCs. To also remove formaldehyde and other VOCs, (chemical off-gassing) you will need an air purifier with additional technology.
