HEPA filters are very specialized and have absolutely no place in the
home..


I have allergies. I also have HEPA stand alone air cleaners in my living
room and bedroom.

During the spring I can be outside and be MISERABLE from the pollen and
whatnot, but can step into my room with a HEPA air cleaner going and almost
instantly get relief!

Why is that?

Why do hospitals have HEPA air filters?

Why do airplanes have HEPA air filters?
