14 Ways Toxins Are Sneaking into Your House

With all the green products, you'd think your home is mostly toxin-free. But some sneaky ingredients and contaminated products still pose a problem.

How clean is your house?

You may scrub, sweep, dust, and declutter, but toxins can still end up everywhere. They're in the air we breathe, the products we use to clean, and all types of essential household items. Even the most innocent-looking products can contain substances that harm health in insidious ways, from triggering respiratory illnesses to disrupting our hormones. Which ones are the biggest offenders? We asked the experts to weigh in.

Through your floorboards

"Radon (a colorless, odorless, and tasteless gas found in soil and rocks) can seep through the cracks and minor gaps of the foundation of the home or a basement floor," says Emily Walsh, a home safety expert for "Prolonged exposure can lead to lung cancer. Since it's a silent toxin, it's important to install a radon mitigation system if radium deposits are common in your area."

With your new carpet

Putting new carpet down is a nice way to update your home, but the new floor covering can release gasses, warns Walsh. "The first 72 hours after installation can pose a major threat to your air quality," she explains. "Volatile organic compounds (VOCs) within the fibers of the carpet are emitted into the home. These toxins include acetaldehyde, benzene, formaldehyde, toluene, and more. Signs of poisoning are symptoms of nausea, headaches, and possible irritation to your nose, throat, and eyes."

Your dry cleaning

It feels good to put dry-cleaned clothing back in your closet, crisp and pressed for your next outing. But the process which made them look brand new could carry some trouble. "Perchloroethylene is a chemical used in dry cleaning," says Luz Claudio, PhD, professor of environmental medicine at the Icahn School of Medicine in New York. "Although it's not known how much of it may be released in the home when you bring dry-cleaned clothes in plastic bags, it may be best to open the bags and aerate them outdoors before bringing inside."

Your mattresses

You may know that bleach and fragrant deep cleaners contain toxins, but there are plenty of other sources you miss simply because they're scent-free. "The flame-retardant chemicals sprayed on our mattresses and furniture have zero scent," says Dimmick, who is also the founder of the natural home cleaning line The Good Home Co. Flame retardants are used to slow the ignition process and prevent fires, so while their intention is good, their side effects are not.

Air fresheners

Particularly during the winter months when the windows are closed, a mist of air freshener or the burning of a deliciously-scented candle can give a room a quick pick-me-up. Don't do it: "Many of the candles we use or the air fresheners are very harmful," says Christine Dimmick, author of Detox Your Home. "They leave VOCs in the air. We breathe them, and they can build up in the body, leading to problems like asthma." These 11 household items are literally poisoning your air.

In "natural," "clear," and "-free" products

Product names can imply their contents are safe or natural even when they're not. If you see a long list of ingredients, you're most likely getting exposed to a few chemicals you'd be better off avoiding. And remember that just because something is scent-free doesn't mean it's safe. "With laundry detergent, even the ones that are advertised as free and clear have so many ingredients," says Dimmick. Because no government agency regulates the wording on labels, manufacturers can slap on any claims they like, she says. Check out 15 chemical-free ways to clean your home.

Polluted indoor air

"Indoor air can be up to several times more polluted than outdoor air," says Harris. She cites air fresheners, scented plug-ins, and candles as the biggest culprits, following by the release of gasses from cleaning products—even when they aren't in use. Harris recommends scenting your home by with essential oil diffusers or clean-burning candles with lead-free wicks.

Household dust

"Research indicates that common household dust contains a lot of toxins," says Tonya Harris, founder of Slightly Greener. "Studies have found flame retardants, endocrine disruptors (toxins that interfere with our body's hormones), and lead in common household dust." What can you do to combat it? Harris suggests buying safer cleaning products to cut down on the toxic load in your home, and then vacuum frequently with a HEPA filter-equipped machine.

Self-care products

Sometimes a toxic ingredient may not appear on a product label, but it can still contaminate what's inside, says Harris. One example is of formaldehyde releasers, and they turn up in nail polish, shampoo, shaving cream, and even baby wash. Harris explains how they work: "These are chemicals that decompose slowly over time to produce and release formaldehyde (a known cancer-causer), which acts as a preservative for personal care products and cosmetics. So, although formaldehyde itself hasn't been added to the product and doesn't need to be listed on the label, you still risk exposure to it."
