The indoor air is chocked full of harmful pollutants, 200% to 500% higher than outdoors! Dust-mites thrive in this filth deep down in the carpet. It is invisible to the eye but very visible to the arteries and lungs. Every time someone moves across the carpet they stir up these pollutants into the air, and can stay there for an hour or more. The average active home will always have these particles in the air, which is especially harmful to people with asthma and allergies, but not good for anyone, allergies or not!
During cold seasons this helps keep people sick. As we all know your kids spend a lot of time on the carpet. This is why we believe carpet cleaning is foremost a health issue and secondarily an appearance issue.
