What is a Honeywell True HEPA Filter?

HEPA stands for High Efficiency Particulate Air.

HEPA filtration is recognized as one of the most efficient ways known to remove airborne particles and is almost exclusively used in medical, laboratory, and commercial applications where substantially clean air environments are required for human health and safety.All Honeywell HEPA Air Cleaners Feature True HEPA Filters.

True HEPA filters are certified to have a minimum effectiveness of 99.97% in capturing particles as small as 0.3 micron size from air passing through it. Particles of 0.3 micron size are the most difficult size particles to remove from the air, and easily pass into the body's respiratory system. This size is specifically used in the testing of Honeywell's True HEPA Filter.

Honeywell's true HEPA filter is made of a special fibrous material that features an extended surface that is deeply embedded with randomly positioned glass fibers. This complex network of fibers is extremely effective at trapping very small particles as air moves through it.

Honeywell and the AMERICAN LUNG ASSOCIATION are partners in the national program to educate the public about the hazards of poor indoor air quality and ways to protect their lung health. The enclosed information is from the ALA and is part of our educational efforts. For further information from the ALA, call 1-800-LUNG-USA.

How Big is 0.3 Microns?

As shown by the chart below, these common airborne irritants are 3 to 100 times larger than a 0.3 micron particle. The Honeywell true HEPA filter is even more than 99.97% effective at capturing these larger airborne particles when they become airborne and circulate through the air cleaner.

Honeywell's True HEPA filter is effective at removing these common airborne irritants which are 3-100 times larger than 0.3 microns.

Particles are graphically depicted and enlarged to show relative size. Particles less than 10 microns in size are not visible to the human eye.

Air Cleaning and Indoor Air Quality

The U.S. Environmental Protection Agency considers indoor air pollution a high priority health risk. The quality of indoor air impacts human health. The average American spends nearly 90% of their time indoors, and more than half of this time in the home. With the move towards more energy efficient building construction and less ventilation with outside air, indoor air quality can suffer.

A three tier strategy for reducing indoor air pollution includes source control, ventilation and air cleaning. Honeywell enviracaire HEPA Air Cleaners should be used as an effective part of your program for improving the air quality in your home or office.
