This isn't the most pleasant thought ever, but your carpet in chocked full of bacteria. On average, a standard home carpet counts about 200,000 bacteria thriving between its fibers. This is an impressive number, indeed. As hard as it may be to believe it, your carpet is actually the dirtiest item in your house. It may even be more bacteria heavy than your toilet seat. This isn't only disgusting, but also a huge health hazard to your family.
