The best air purifiers for such a task he says are high efficiency particulate air hepa filters which can pluck out particles that are as small as five micrometers or one millionth of a meter.
Best high efficiency air filter.
If you choose a purifier with a hepa filter or high efficiency particulate air filter it should remove about 99 96 percent of all airborne particles but there are other kinds of air purifiers.
Furnace efficiency is one thing.
Hepa stands for high efficiency particulate air hepa filters are physical filters designed to clear out at least 99 7 percent of particulates that are 0 3 microns or larger in size.
Air filters also help keep your furnace s coils and heat exchangers clean which may prolong furnace life and keep it running efficiently.
High efficiency air filters are a cost effective way to help improve indoor air quality which may be beneficial to family members sensitive to allergens and other particles in the air.
