EPA studies show that most Americans spend 90% of their time indoors and the level of pollutants may be 200% to 500% higher than outdoors, even in cities with a lot of air pollution. Trane, a leader in air handling systems, claims a 1,500 sq ft area will normally generate about 40 lbs of dust every year! An ounce of this dust can hold up to 40,000 dust mites. Everyday 72 trillion allergens can make their way into your home and every time someone walks across the carpet can release these pollutants which can stay airborne for hours. This is why we believe carpet cleaning is foremost a health issue and secondarily an appearance issue.
