After having carpet in our homes, and several houses, when we had it removed I was amazed at the dirt, grit, human and pet hair, and skin particles being fed on by dust mites. The bottom line, carpet is nasty regardless of how you keep it and how many times it is professionally cleaned. We now have beautiful wood floors and love them. So easy to clean, so durable, and adds beauty to our home and travel trailer.
If you have allergies, or your pets have allergies and you have carpet.........never mind. Go look under the carpet and you'll see why. It is just nasty under there! And that affects the environment we live in and live with every day.
