HEPA air filters are a special type of pleated mechanical air filter.
These air filters remove 99% of all mold, mildew, dust, allergens, and indoor contaminants.
Many air cleaners require an air filter, but they do not require these filters to be a high efficiency particulate air filter. HEPA filters are definitely better than others. HEPA filters have a better rating for trapping different types of indoor air particles. I regularly use a HEPA filter for my air purifier. I’ve been suffering from indoor allergies since I was a kid. At times the allergies can be absolutely awful. I have suffered for a very long time. When I was an adult, I worked at a store with an air filtration system and my allergies were practically non-existent. At that time, I decided to find an air cleaning machine for my apartment. I started off with something very small for the bedroom, but now I have an advanced air filtration system in my home that would compare to any hospital, doctor’s office, or laboratory. I found a job working from home, so I get to enjoy all of the luxuries of having a great air purifier all day and all night. A lot of people wouldn’t pay all of the extra money to have the upgraded system in the home, but I know for sure that it works and my health is much better thanks to the air cleaning machine and HEPA air filters. I barely have trouble with allergies and I don’t even have to take a pill every day now.
