Hepa Air Purifiers-what They Are, What They're Good For And Why They Work

By:


HEPA air purifiers are mentioned ever more frequently as the awareness of the link between air quality and health has become more apparent. Here's everything you always wanted to know about this type of air cleaner, and why it should be part of your indoor air quality solution.

What Is A HEPA? The term is an acronym for high efficiency particle arresting. To be designated as such it must be able to remove 99.97% of airborne particulates that are.3 microns or greater (with a micron being defined as one millionth of a meter).

The benefits of this technology are that out of every 10,000 airborne particles floating in your space, it will remove 99,997 of them with 97% efficiency. This is same type of filtration that hospitals use to insure clean air.

What Are They Good For? So you're probably saying, that's great, next time I'm in a hospital I'll be glad. But these filters have an important role to play in homes and offices as well.

The United States Environmental Protection Agency states that indoor air is 20 times more polluted than outdoor air. And many of these pollutants are particles that fly around in our air. Regardless of how clean you keep your home, it still has dust, dust mites, mold and mildew spores, seasonal pollens, and bacteria and viruses that often attach to all of the above.

And more specifically, they can remove bird dust and dander, hair and dander from dogs and cats. Purifiers with this type of filter are often used by commercial aviaries, dog groomers and breeders and other professional who deal with a large number of particulates.

By removing these particulates while they are airborne, you can avoid the onset of respiratory problem such as allergies and asthma, and you can avoid making pre-existing conditions worse which makes for a cleaner, healthier environment.

Why They Work? Particles that are.3 microns or bigger cannot get through the incredibly tiny holes in this type of filter. Because it is usually made of fibers that are pleated, it forms a very dense barrier that is extremely effective at trapping particulates.

The efficiency of HEPA filters can be enhanced with large and medium particle pre-filters, and with carbon cloth. Without these additional filters, the life expectancy is about one year. With these additional filters, the filter life jumps to approximately 5 years.

Making use of this type of filtration can greatly enhance indoor air quality. And that will lead to a healthier more productive life for all.
