Carpeting believe it or not, is one of the biggest contributors to indoor air pollution.
One of the commonest health problems in a house is allergies, and carpets are practically an ideal environment for dust mites, molds and mildew.
Also, but the modern wall-to wall carpeting in the modern houses are made of synthetic fibers treated and dyed with chemicals (fungicides, soil repellents and pesticides, anyone?) and bonded with chemical glues. All those materials release hundreds of Volatile Organic Compounds as they age, in a process called out gassing. Volatile Organic Compounds (VOCs) can be carcinogens, irritants and mutagens. Not the perfect thing to have in your house, to say the least.
Carpeting also attracts and retains all that your household members and you track in the house in the ground outside- dirt, lead other unhealthy debris as well as dust uncovered in flaking house exterior paint, insects, bacteria, yard and garden chemicals. Not to mention food crumbs, hair and skin particles that are dead.
Finding a wall-to-wall carpet 100% clean is almost impossible (ever let one of those steam-cleaners to scrub your carpet and cleaned the same area over and over, whenever seeing more dirt come out?) and trying to clean causes its own difficulties. Vacuuming stirs up mold spores and airborne dust. Shampooing can leave a damp carpet supporting more mold growth and yet the shampoo may have irritating or even hazardous substances added.
In another end health spectrum is ceramic tile. It’s produced from natural clay materials fired in a kiln. A tile varnished with non-leaded glaze is impervious to bacteria and mold and is well tolerated by sensitive people.
Ceramic tile is bonded to the foundation flooring using low-toxicity thin set mortar, and can be grouted with homemade, additive-free grout. 2 components dry, clean sand blended with 1 part Portland cement could be ready and added to water to form a slow, damp healing grout.
Although a ceramic tile flooring may be expensive up front, on account of the installation that was labor-intensive, they are really permanent and long lasting if correctly preserved, and will be regarded as relatively affordable in the long run.
