Quality floor mats improve indoor air quality (IAQ) and safety in commercial and residential applications. Studies have shown that most toxic chemicals that end up inside a home are tracked in on people's shoes. A well-used door mat can trap and hold dirt and allergens, preventing their spread into the rest of the building, significantly improving IAQ and reducing the need for extensive cleaning. Additionally many floor mats are resistant to welding sparks and can keep employees from slipping on industrial lubricants or water.
