Air Purifier Filter: HEPA Standards?

The most important specifications of air purifiers are the air filters. Today, there are two major types of filters that are used in modern air purifiers and ionizers. People often do not know the difference between a HEPA and HEPA type filter. A true HEPA filter captures more than 99.7 percent of common air allergens. A HEPA type filter captures less allergens, which could be as low as 85 percent. In some air purifiers, there are permanent air filters that only need to be washed or vacuumed. This eliminates the costs associated with replacing the traditional filters every several months.
