How to Keep Toxic Chemicals Out of Your Home
Simple actions and informed choices can dramatically reduce toxic chemical exposure in your household and protect your family’s health.
Modern homes can be unwitting repositories for hundreds of toxic chemicals—many found in everyday products we use for cleaning, maintenance, beauty, and personal care. From kitchen sprays and air fresheners to furniture and flooring, hidden hazards are everywhere, posing potential risks to our health and wellbeing. Fortunately, by understanding these dangers and taking action, you can reduce your exposure and create a safer home environment.
Understanding the Risks: Where Toxic Chemicals Lurk
Most conventional household products—including cleaners, laundry supplies, paints, furniture, and even personal care items—contain chemical ingredients that can act as irritants, allergens, endocrine disruptors, or even carcinogens. While single exposures to low doses may seem harmless, the real concern is the chronic, cumulative effect from routine, long-term use. These exposures contribute to our ‘toxic body burden,’ the amount of chemicals that accumulate in our tissues over time, and have been linked to difficulties such as asthma, reproductive disorders, hormone imbalances, and developmental problems.
Why Are Toxic Chemicals So Prevalent?
In the United States, there is little federal oversight regarding chemicals in household products. Manufacturers are not required to test most ingredients for safety before bringing them to market, nor do they must disclose all ingredients—especially if they’re considered ‘fragrance’ or proprietary blends. This means it’s often up to consumers to identify and avoid questionable products or ingredients.
Common Symptoms and Health Risks
- Asthma and other respiratory issues
- Skin rashes and allergic reactions
- Irritation of eyes, nose, and throat
- Potential links to cancer, hormone disruption, and neurotoxicity
Biggest Sources of Toxic Chemicals in the Home
Here are the most common household sources and how you can address them:
1. Cleaning and Disinfecting Products
Conventional cleaners often contain chlorine bleach, ammonia, artificial fragrances, and other harsh additives. These compounds can irritate airways, burn skin, and pollute indoor air. Worse, some ingredients have been associated with hormone disruption and long-term health impacts.
- Phthalates: Common in scented products; linked to hormonal disruption.
- Bleach and ammonia: Potent irritants; dangerous if mixed.
- Quaternary ammonium compounds (‘quats’): Found in disinfectant wipes and sprays; linked to respiratory problems.
How to Avoid
- Choose certified non-toxic cleaners or make your own using simple ingredients like vinegar, baking soda, and castile soap.
- Avoid products labeled with only generic terms like ‘fragrance,’ as these can contain dozens of undisclosed chemicals.
- Read ingredient labels and avoid bleach, ammonia, synthetic fragrances, quats, and dyes.
2. Synthetic Fragrances
Artificial scents are widespread in air fresheners, laundry products, candles, and personal care. These can contain dozens of non-disclosed chemicals—many of which are harmful to your health. Symptoms from exposure can include headaches, allergic reactions, asthma attacks, or even hormonal effects over time.
What others are reading
- Opt for unscented or naturally scented (essential-oil-based) products.
- Avoid plug-in air fresheners, commercial room sprays, and artificially-scented candles.
- Regular cleaning and good ventilation are the best way to keep your home smelling fresh.
3. Pesticides and Insecticides
From bug sprays to rodent traps and garden chemicals, pesticides are designed to be toxic. Many legacy pesticides, like DDT or strychnine, were banned for health reasons but may still linger in old storage areas. Others in use today can be just as risky if misapplied.
- Switch to natural pest deterrents like diatomaceous earth, neem oil, traps, or barriers.
- Inspect old containers for banned chemicals. Dispose of unidentified or antique products at hazardous waste facilities—never in regular trash or drains.
- Minimize indoor and garden pesticide use by focusing on prevention and non-toxic approaches.
4. Building Materials and Furnishings
Construction and decor materials can emit dangerous volatile organic compounds (VOCs) and other toxins. Common offenders include particleboard furniture, new carpets, vinyl flooring, adhesives, and paints, especially in older homes.
- Seek ‘no-VOC’ or ‘low-VOC’ paint, finishes, and sealants.
- Prefer solid wood or certified non-toxic particleboard for furniture.
- Air out new furnishings and remodeling materials before moving them indoors.
- If living in a property built before 1978, check for lead paint and have abatement professionally managed if needed.
5. Flame Retardants
Flame retardants are commonly used in upholstered furniture, baby products, mattresses, and electronics. These chemicals have been linked with neurodevelopmental and reproductive harm.
- Shop for items labeled ‘flame retardant free’ or compliant with modern regulations (e.g., TB-117-2013 in California).
- When replacing furniture, prioritize products made without added flame retardants.
6. Personal Care and Laundry Products
Soaps, lotions, cosmetics, and detergents often contain parabens, phthalates, preservatives, dyes, and other irritants that can build up in our bodies or pollute waterways.
- Choose simple and fragrance-free personal care items, or review brands on databases such as EWG’s Skin Deep Cosmetics Database.
- Select laundry products with minimal, plant-based ingredients and without artificial scents or optical brighteners.
- Dry clean sparingly. When necessary, ask for ‘wet cleaning’ or air clothes thoroughly after dry cleaning.
Proven Steps to Reduce Chemical Exposure at Home
1. Leave Shoes at the Door
Shoes pick up chemical residues, pesticides, and heavy metals from outdoors. Always remove them before entering your living spaces, and use a doormat to further limit the transfer of toxins indoors.
2. Clean Dust and Surfaces Regularly
Household dust is a major carrier for many contaminants, including flame retardants, pesticides, lead, and phthalates. Wet-mop floors, wipe hard surfaces with damp (not dry) cloths, and vacuum with a HEPA filter to reduce airborne particles.
3. Air Out Your Home
Open windows or use mechanical ventilation regularly to expel indoor pollutants and let in fresh air. Air out new furnishings, dry-cleaned clothes, and purchases with strong odors outside before using them indoors.
4. Use Kitchen Ventilation
Cooking, especially on gas stoves, releases chemicals and particulates into your air. Use a range hood or exhaust fan to keep indoor air cleaner and remove cooking fumes.
5. Avoid Scented and Aerosol Products
Artificially scented sprays, aerosol deodorizers, incense, and candles contribute to poor indoor air quality. Limit their use or eliminate them entirely in favor of simple ventilation and natural alternatives.
6. Be Careful with Renovations
If you’re remodeling or repainting, select materials with the lowest emissions possible and give everything time to off-gas before daily use. Never attempt to remove old lead paint yourself; hire an EPA-certified contractor for safe abatement.
7. Buy Fresh, Whole Foods
Minimize the purchase of highly-processed packaged goods, which may contain synthetic additives and can add to your home’s chemical load via packaging or preservatives.
Safer Alternatives and Smart Shopping
Creating a healthy, low-toxin home is not about buying every new ‘eco-friendly’ product. Instead, it’s about making informed choices and simplifying wherever possible:
- DIY Cleaners: Make your own all-purpose cleaner with vinegar, baking soda, water, and a few drops of pure essential oil if scent is desired. This cuts down dramatically on exposure to commercial chemical mixes.
- Choose Certified Safe Goods: Look for certifications such as Green Seal, Safer Choice, USDA Organic (for textiles), and products rated well in the EWG’s Healthy Living or Skin Deep databases.
- Buy Used or Vintage with Caution: Older furniture may contain lead paint or chemicals that are now banned. Refinish, repaint, or seal vintage pieces to limit risks, or prioritize newer certified-safe alternatives.
- Don’t Rely on Labels Alone: Learn basic ingredient terminology and know what to avoid (see table below).
| Ingredient to Avoid | Typical Use | Safer Swap |
|---|---|---|
| Phthalates (in fragrance) | Scent in cleaners, laundry, personal care | Fragrance-free products, pure essential oils |
| Bleach (sodium hypochlorite) | Disinfectants, mold removers | Hydrogen peroxide, steam cleaning, vinegar (not mixed) |
| Ammonia | Glass & surface cleaners | Vinegar & water for glass, soap & water for surfaces |
| Formaldehyde (in pressed wood, fabrics) | Furniture, paneling, window coverings | Solid wood, certified low-emission alternatives |
| Triclosan | Antibacterial soaps, toothpastes | Plain soap and water, fluoride toothpaste |
Proper Disposal of Toxic Substances
Never pour chemicals down the drain, toilet, or onto the ground. Many products—such as old pesticides, paints, automotive fluids, or cleaning solutions—are classified as hazardous waste. Here’s how to dispose of them safely:
- Contact your local municipality or waste management authority for hazardous waste collection sites and scheduled drop-off days.
- Keep items in their original containers for easier identification by disposal professionals.
- Never mix chemicals, as this can cause dangerous reactions.
