Waking up to the warmth of carpet beneath your feet is even better when you know that whats covering your floor is also helping you to breathe easier. Carpet keeps the air you breathe cleaner by trapping dust particles and other allergens until they are vacuumed away. In fact, a number of studies show that with regular use and dry cleaning, carpet allows significantly fewer particles into the air than smooth flooring like hardwood or tile. Clinical testing has shown that people who lived in homes with wall to wall carpet showed fewer symptoms of asthma and allergies than those without.
