Are cleaning and dusting actually making your indoor air quality worse?

By Catherine Poslusny

Even when your home is sparkling clean, there may still be chemicals and allergens lurking in the air. In fact, cleaning is probably responsible for many of them. Dusting is another air quality culprit, as we usually just stir up dust particles (and their many gross or toxic ingredients) making them airborne and worsening our indoor air quality (IAQ). To improve your IAQ while cleaning, look at the cleaning product you’re introducing and then try rethinking your dusting routine. The best eco-friendly cleaning products are safer for your home’s occupants and the environment.

Traditional cleaning and disinfecting products and procedures, especially air fresheners, can linger in the air long after use, exposing your household to potentially harmful chemicals. Once airborne, dust and chemicals float around your home until they find a way outside. This can take a while in older, drafty homes and tightly insulated homes with energy-efficient doors and windows. Often, dust and chemical residues settle on the surfaces in your home before they’re vented. Then, the cycle starts over again the next time you clean.

Ditch your old dusting routine

Household dust can have a major impact on your indoor air quality. You may have heard that dust is made up of mostly dead skin cells, but they’re far from its only ingredient. Dust also contains many allergy triggers, such as dust mite particles and droppings, mold spores, pollen, cockroach particles, and animal fur, dander, and saliva.

Aside from triggering allergy and asthma symptoms, dust may also contribute to other health problems. A 2016 review of dust exposure studies found household dust to contain many harmful chemicals, including phthalates, environmental phenols, flame retardants, combustion byproducts, fragrances, and fluorinated chemicals. Toxic chemicals in dust may harm the reproductive, digestive, respiratory, and nervous systems, and they’re linked to various cancers and other health problems.

So, dusting is essential to cut down on allergens, chemicals, and other pollutants in your indoor air. But dusting the wrong way could actually make the problem worse. Traditional dusting tools, such as feather dusters and dusting sprays, don’t actually get rid of dust. They send it back up into the air you breathe, then it may re-settle.

The best eco-friendly cleaning products pick up and remove all these harmful chemicals and particulates from your home. Use a vacuum cleaner and microfiber cleaning cloths to trap and dispose of dust without stirring it into the air. Remember these oft-missed dust magnets:

  • Light bulbs and fixtures
  • Vent covers
  • Furniture undersides and supports
  • Cabinet and closet shelves
  • Blinds, curtains, and other window treatments
  • Ceiling fans

Remember your filters!

The filter in your HVAC system does much of the heavy lifting when it comes to removing airborne dust and other particles. Next time you replace your filter, check the packaging for a Minimum Efficiency Reporting Values (MERV) rating to understand how well the filter can trap airborne particles. The higher the MERV rating, the better it is at capturing particle pollution. HEPA filters are the most efficient mechanical filters for trapping dust, pollen, mold, and other particles in the air.

Unfortunately, replacing your HVAC filter isn’t as simple as picking the most efficient one and popping it in. The better a filter is, the harder your HVAC system has to work to push air through it. Talk to an HVAC professional if you’re not sure which level filter your system can handle. Whatever you choose, make sure to replace it regularly according to the manufacturer’s recommendations, as old, dirty filters can clog your HVAC system and circulate dust and debris right back into the air.

Vacuum cleaners and air purifiers also come with filters of varying efficiency. As with your HVAC system, you want to use the best filter that your appliance can handle. (HEPA is the gold standard here too, so do your research before purchasing that robot vacuum.) Don’t forget to clean and/or replace your vacuum and air purifier filters regularly, according to manufacturers’ instructions.

Seek out the best eco-friendly cleaning products

Most cleaning products on grocery store shelves contain strong chemicals and synthetic fragrances that may damage your health. Some of these chemicals are volatile organic compounds (VOCs), which quickly evaporate at room temperature and pollute indoor air. Exposure to VOCs from cleaning products may cause increased risk of new-onset asthma and other respiratory effects.

Product labels can be misleading, and it’s not always easy to tell whether a cleaning solution contains harmful fragrances or VOCs. The EPA Safer Choice label can help you identify which products are safest to use around your family and pets (while still getting the cleaning job done). You can search for different types of Safer Choice certified cleaners here.

An even better way to make sure your cleaning products won’t pollute your indoor air? You can make some of the best eco-friendly cleaning products yourself. Vinegar, baking soda, lemon, and water can be combined in many ways to tackle most cleaning jobs around the house. There’s a reason these ingredients have been cleaners for centuries—they really work!

Note: Baking soda and vinegar are great for most of your cleaning needs, but they aren’t disinfectants. If you’re worried about mold, bacteria, and viruses, check out Elemental Green’s guide to eco-cleaning and disinfecting, provided by our friends at Green Seal.

Go green when you clean

The toxic chemicals in some cleaning products aren’t just bad for your health; they can also harm the environment. Cleaning solutions released into the air by spraying or through VOC evaporation negatively impact IAQ and contribute to outdoor smog. When rinsed down the drain, toxic cleaning chemicals may contaminate groundwater, rivers, and streams, where they can disrupt wildlife and potentially enter the food chain. And, of course, a product’s plastic packaging will likely end up in a landfill, or worse. Circularity is always key. Note that Swiffer or other disposable products may be effective and safe for your IAQ, but they will add to your waste stream.

An increasing number of brands have begun marketing their products as “environmentally friendly,” “eco-safe,” or “green.” These terms aren’t regulated, so they don’t guarantee that a product is actually safe for the environment. Beware of “greenwashing” (an ironic term in this instance), and, again, transparency on ingredients lists.

In addition to the Safer Choice and Green Seal programs, eco-safe products may also carry certifications from the EPA’s Design for the Environment program, the Environmental Working Group’s EWG VERIFIED, Ecologo, and Cradle to Cradle. We’ve found Amazon’s ability to sort products by green certification very helpful.

Some of the best eco-friendly cleaning products we found include:
