Although we might not normally associate carpet with improved indoor air quality, it does have a very positive effect. A misperception is that people with asthma and allergies should avoid carpet in the home. But much of today’s carpet is made from harmless materials found in clothing and other everyday fabrics, such as polyester, nylon and olefin fibers, which don’t trouble most people.  Gravity causes common household particles, such as dust, pollen and pet and insect dander, to fall to the floor. Carpet fibers trap the particles, reducing their continued circulation in the air. Proper cleaning with Carpet & Rug Institute approved vacuums effectively removes dust and allergens from the carpet, locks them in the machine and helps keep them out of the air we breathe.  For more information about indoor air quality, go to [www.carpet-rug.org]
