According to the Environmental Protection Agency (EPA), indoor air may be up to five times more polluted than outdoor air. Given the fact that most people spend 90% of their time indoors, the EPA has ranked poor indoor air quality as one of the top five environmental risks.

THE EFFECTS OF INDOOR AIR POLLUTION

No home, no person, is immune to indoor air quality problems. Research shows that the place where people feel most secure—home sweet home—is the place that can be most harmful to their health. With fresh coats of paint and plush carpeting, new homes tend to have higher concentrations of chemicals. Older homes are breeding grounds for mold and mildew. And all homes, no matter how clean they appear, are contaminated with dirt and dust.

The effects of pollutants on a person’s health depend on a number of factors, including age and immune system strength. Think of this in terms of barrel sizes. A healthy adult has a large barrel. An adult with allergies has a medium barrel. And a young child, senior or person with a respiratory ailment is likely to have a small barrel.

For each individual, the barrel continually fills with pollutants until it potentially overflows and symptoms appear. Therefore, those with small barrels face the greatest risk.

The Mayo Clinic has found that air cleaners attached to whole-house systems are generally more effective than freestanding air cleaners. An optimal solution for central HVAC systems, the PureAir System installs easily on the air handler (return airside)*, where a filter would typically be placed. By removing and destroying odors and chemical vapors, it helps increase the efficiency and reliability of HVAC systems.

THE MOST EFFECTIVE STRATEGY FOR CONTROLLING INDOOR AIR QUALITY

The new PureAir™ Air Purification System removes pollen, dust mites and mold spores. And it safely removes and destroys odors and chemicals.

HEALTH IMPROVEMENTS

The PureAir™ Air Purification System helps clean the air and provide respiratory relief by capturing and removing particles and bioaerosols as small as 0.3 micron. This minimizes your customers’ exposure to potentially harmful pollutants. (Particles smaller than 2.5 microns pass through the lungs and into the bloodstream, increasing the possibility of illness.) Plus, the PureAir System is the only single indoor air quality system that can safely remove and destroy odors and chemicals such as tobacco smoke. Of the compounds found in smoke, more than 40 are known to cause cancer, and many others are strong irritants.

THE PUREAIR™ PCO PROCESS INVOLVES THREE STEPS:

1. The pleated, 4" MERV 9 filter captures particles and bioaerosols as small as 0.3 micron, removing them from the airstream.

2. As the odor- and chemical-filled airstream flows over the catalytic surface (titanium dioxide-coated mesh filter), they are exposed to intense ultraviolet light.

3. The light energy activates the titanium dioxide 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. The conversion process occurs as the carbon component of the odors and chemicals react with the hydroxyl radicals, creating a permanent bond.

NOW THAT YOU UNDERSTAND HOW THE PUREAIR™ SYSTEM WORKS, YOU'RE PROBABLY WONDERING HOW WELL IT WORKS.

Research has shown that total volatile organic compounds are reduced by 50% within a 24-hour period in a typical residential home. These studies prove that PureAir is the most effective single air purification system on the market.

PUREAIR™ SYSTEM MAINTENANCE

For optimal performance, the UVA lamps need to be replaced annually. These lamps are designed specifically for the PureAir™ unit, so they must be ordered from Lennox.

The pleated media filter should also be replaced annually. If the home’s level of airborne particles is high, the filter may need to be changed more often.

The metal insert/catalyst should be rotated every year and replaced after five years of operation. Rotating the insert allows any buildup of carbonaceous material (a yellow stain) on the outgoing side to be burned off by the lamps.

USING THE PUREAIR™ SYSTEM WITH OTHER IAQ PRODUCTS

Many Lennox Healthy Climate™ products work well in conjunction with the PureAir System. In particular, the Healthy Climate Germicidal Lights are extremely effective when positioned near air conditioning coils.
