(NewsUSA) - Yellow, pollen-covered cars and red, itchy eyes. These may be the colorful, tell-tale signs of allergy season, but experts are focusing on raising awareness of the allergy triggers you can't see. The Breathe Easier campaign by Aprilaire, a leader in indoor air quality for more than 60 years, is dedicated to communicating the importance of clean indoor air and whole-home air cleaning as part of an integrated approach to respiratory wellness and allergy-related issues. The medical community is also supporting the critical cause.

"As with all health issues, it's imperative to be proactive, and maintaining clean indoor air is critical to overall personal wellness," said Dr. Clifford Bassett, assistant clinical professor of medicine at The Long Island College Hospital, board-certified allergist and immunologist, and medical director of Allergy and Asthma Care of New York. "Twenty years ago, no one knew about the connection between taking aspirin and mitigating the signs of a heart attack. Now most of us do. That's the exact type of gradual evolution we hope to secure regarding the importance of clean indoor air to respiratory health, especially for patients with respiratory ailments such as allergies and asthma."

According to the 2007 "AirAdvice State of Our Indoor Air" report, 96 percent of homeowners reported having at least one type of indoor-air-quality problem. Multiple indoor airborne allergens and pollutants like dust, pollen, viruses, bacteria, pet dander and mold spores can affect health, comfort and safety and can compromise overall quality of life.

Home air cleaning systems can help clean the air and capture airborne contaminants.
