All HEPA Air Cleaners clean the air in the room or open area they are operating in. Usually people place Indoor Pollution HEPA cleaners to the rooms they spend most of the time: bedrooms, living rooms and home offices.

HEPA material does not look like a screen or a colander. Instead it looks like a very thin bail of fibers. Thus the air has to find a route through this maze of fibers. So first a particle runs into a fiber and sticks.

Secondly, the particle gets within one diameter of a fiber of the HEPA filter and while it tries to escape the fiber it gets stuck on the fiber. Therefore, HEPA filter catches 99.97% of particles.

HEPA Air Cleaners are best for removing out-gassing chemicals, airborne allergens, and odors from your indoor air environment. The added feature to a high quality Indoor Pollution HEPA Air Cleaners can be the medical grade ultra-violet light system or EGF system which quickly kills viruses, bacteria and fungi. Usually these types of HEPA cleaners are called HEPA Air Purifiers.

Both HEPA air cleaners and HEPA air purifiers only allow very tiny particles to pass through. In fact they can remove particles down to 0.3 microns. When choosing Indoor Pollution HEPA Air Cleaners and HEPA AIR purifiers it is important to measure your room and identify the allergens you are allergic to.

Having a full understanding of this factor is essential in determining which HEPA air cleaner or air purifier is designed to remove that particular allergen and for the particular size of the room.

Ozone-Ionizer Air Purifiers are often confused with HEPA filtered Air Cleaners and Air Purifiers.

In fact ozone purifiers work quiet different. Ozone is naturally occurring gas. It is created by nature when lightning cuts through the oxygen molecule in the air.

When Ozone purifier operates it creates a smell of thunderstorm or waterfall. Combined with Ionizer, specifically with new radio ionization technology it significantly removes dust, allergens, smoke particles, and is also effective against chemicals and microorganisms.

The downside of Ozone air purifiers is that if used without reading the factory instruction it may irritate your mucus membranes. So we highly recommend sticking to the outlined usage rules that factories provide in order to avoid unnecessary side effects.

If you've got a serious lung disease or sever allergy we recommend that you stick with Indoor Pollution HEPA air purifier or air cleaner, like Austin Air HEAP Air Cleaner or Honeywell 50200 True HEPA Air Purifier.
