LENNOX PUREAIR™ AIR PURIFICATION SYSTEM

The PureAir system reduces concentrations of pollutants through a process called photocatalytic oxidation (PCO). Similar to the process used by the Department of Defense to combat germ warfare, PCO combines nature’s three most powerful air purifiers:

1. Ultraviolet light
2. Titanium dioxide, a nontoxic substance found in the earth’s crust
3. Hydroxyl radicals, particles derived from hydrogen peroxide

The PureAir PCO process involves three steps:

1. The pleated media filter captures particles and bioaerosols like pollen and pet dander, removing them from the airstream.
2. As the odor- and chemical-filled airstream flows over the UVA light, the airstream is exposed to the catalytic surface (titanium dioxide-coated mesh filter).
3. The light energy activates the catalyst, which generates hydroxyl radicals. These particles, which are more than twice as powerful as chlorine, break down the odors and chemicals into carbon dioxide and water.

“Indoor air quality,” or IAQ, is a relatively new topic in environmental safety. While a lot of attention has been placed on outdoor pollution over the past few decades, the focus on indoor air quality is just beginning. The quality of a home’s air mainly has to do with the amount of pollutants inside, but it’s also determined by humidity and ventilation levels. The U.S. Environmental Protection Agency has found that concentrations of pollutants can be up to 100 times higher indoors than outdoors. The American Lung Association estimates that most people spend 90% of their time indoors, so clean indoor air is very important.

There are some basic strategies for outsmarting indoor air pollution:

Eliminate

The first step toward better indoor air is to identify the sources of air pollutants and remove as many as possible from your home. You can decrease the amount of dust and dirt in your home by cleaning and vacuuming at least once a week. You should also regularly wash bed linens and stuffed toys. If someone in your family is sensitive to fumes, you should safely store household products and use them only when necessary. If you need help determining if you have a problem with pollutants, contact your local Lennox dealer to evaluate your home and indoor comfort system.

Ventilate

Today’s modern homes are well-insulated and sealed to conserve energy, which means airborne pollutants have no way to escape. Healthy Climate® ventilation systems help remove allergy-aggravating particles and germs by exchanging stale, recirculated indoor air with fresh, filtered outside air.

Clean

Although cleaning and ventilating helps reduce indoor air pollutants, these simple fixes are not cure-alls. Some contaminants are so small that they may escape through the vacuum or never land on a surface. Healthy Climate® air cleaners and high-efficiency air filters capture even the smallest of particles and germs. Germicidal lights kill them. And a PureAir™ air purification system goes a step further; it removes particles, germs, and odors, and it destroys chemical vapors.

Monitor

Improper humidity levels and high temperatures can actually increase concentrations of particles and germs. An icomfort Wi-Fi™ touchscreen thermostat or ComfortSense® programmable thermostat regulates moisture levels and temperatures to improve indoor air quality and enhance comfort.

Poor indoor air quality (IAQ) can be the cause of numerous health problems. Medical groups report that as many as half of all illnesses are caused or aggravated by indoor air pollution. Pollutants in your home’s air can cause dizziness, headaches and nausea, plus aggravate allergies and asthma.

Clean indoor air benefits everyone, even people who have never suffered from allergies. By removing airborne dust particles from the air, the amount of exposure the respiratory system has to them is greatly reduced.
