Carpets that are made of synthetic fibers like nylon, polyester, polypropylene (olefin) and acrylic are petroleum products. Petroleum off gases volatile organic compounds (VOCs). VOCs are carbon-based compounds that evaporate easily when they are exposed to the air. VOCs are the source of the "new paint," "new carpet" and gasoline smell. Carpets also have fire retardants, which are very toxic, and they have semi-volatile organic compounds (SVOCs). SVOCs are carbon-based compounds that only partially evaporate when exposed to air, so they leave toxic microscopic particles behind. Some VOCs persist even after that new carpet smell is gone, so it is not enough to simply air a carpet out before installing it or to not occupy the house right after the carpet is installed although both of those things are good ideas.
If you are going to buy a carpet made of synthetic fibers, the best thing to do is to buy one that carries a Green Label Plus certification. This certification means that the carpet has reduced levels of VOCs. The certification must include the "Plus" since a standard Green Label certification does not require very high standards for its products. Also, it is important to get a carpet pad that has a Green Label Plus certification. The Green Label certifications were developed by the Carpet and Rug Institute, which is why they include the initials CRI. While the CRI is a trade organization of carpet manufacturers, the testing for certification is done by a third party, so it is a reputable, non-biased certification.
Even a Green Label Plus certified synthetic carpet will off gas because it is a petroleum product. For someone with multiple chemical sensitivities or a compromised immune system or for someone who wants the healthiest carpet on the market, I recommend a wool carpet although they are very expensive.Wool is a natural product (thank you, sheep!), and it does not inherently off gas chemicals. Because wool is naturally fire resistant and stain resistant, wool carpets do not have fire retardants or stain protectors added. Some wool carpets do have added moth proofing, so I recommend asking the flooring retailer about that and avoiding it. Wool carpets also will last a long time - think of the 19th century wool rugs that are still around. There are some people who are allergic to wool for whom a wool carpet would not be suitable.
Whatever kind of carpet you buy, be sure and maintain it by vacuuming it regularly using a HEPA vacuum cleaner. This type of vacuum cleaner uses a high-efficiency particulate arresting (HEPA) filter that captures minuscule particles of dust and pollen that can aggravate allergies and asthma.
All of that said, I really don't recommend carpeting. If you have ever pulled up an old carpet and seen the accumulated dirt, dust and disintegrated carpet pad under it, you know why. Also, most people can't afford a wool carpet, so they are stuck with an ongoing source of off gassing VOCs (their new synthetic fiber carpet).
Do you want to step out of bed onto a warm, soft surface in the winter? Do you want a soft surface in the nursery where you can sit on the floor and play with your baby? Install a hard flooring surface - tile, wood, cement, cork, bamboo, linoleum - and put down a large rug. That way you can periodically pull up the rug, shake it out or send it to the cleaners and clean the floor under it.

When it comes to health, selecting carpet is definitely a choice between bad, better and best, which is to say non-certified synthetic carpet, certified synthetic carpet and wool carpet. You're probably wondering, "So how much more is this going to cost me?" Depending on where you shop, the answer could be "Not a dime more." Last month when I was in a big box hardware store looking at carpets for my mother-in-law's home, of course, I checked to see which carpets were Green Label Plus certified. The store sold only one brand of carpets, its house brand, and they were all Green Label Plus certified, and so were their carpet pads. Green carpets are going mainstream, but be sure that you read the label, and make sure it's the right shade of green.
