The Carpet and Rug Institute maintains a Green Label Plus Program to identify the floor and upholstery products that emit the least harmful compounds. There are no true allergy free carpets, but vacuuming helps maintain a clear, allergy free environment.
The Mayo Clinic recommends removing carpeting and replacing it with hardwood or similar flooring if allergies are a concern. They also suggest that low-pile carpet is best when carpeting is the only option. Shampooing and vacuuming regularly is essential to mitigate carpet-related allergies and vacuums with air filters are helpful.
The Carpet and Rug Institute suggests that clean carpets are actually the best choice for allergy sufferers as allergens do not grow easily in synthetic fibers. The fibers also trap allergens, keeping them out of the air until removal with a vacuum. Carpet also contains fewer of the potentially irritating finishes that may be present in hardwood or aluminum.
The Carpet and Rug Institute's Green Label Program helps identify the best carpet, upholstery and adhesives for use by allergy sufferers. The program also identifies the best vacuums for removing allergens and unwanted particulates. Allergy sufferers and those concerned with home air quality can identify these certified carpets via the Green Label Plus Program logo on approved products.
