Knowing how to improve the indoor air quality of your home can protect your family’s health and help you spend less time cleaning.
So many of us take our indoor air quality for granted. We have walls and windows keeping smog out of our homes, after all. Even smokers often take cigarette breaks outside rather than filling their home with second-hand smoke and odors.
But there is more to improving the indoor air quality of your home, and your family’s health may depend on it.
SOURCES OF INDOOR AIR POLLUTION
In addition to the obvious things like tobacco smoke or unventilated chimneys, there are other less obvious sources of indoor air pollution.
• Mold and mildew
• Organic gasses or volatile organic compounds in paints, chemicals, pesticides, permanent markers, and glues
• Formaldehyde released from permanent-press fabrics, particle board, plywood, and some laminates
• Butane, carbon dioxide, and nitrous oxides used as propellants in aerosol sprays
Some pollutants are things we use in the belief they’ll make our homes cleaner, like the chlorine bleach in laundry or cleaning products, or the propellants and other chemicals in air fresheners. But, over time, these accumulate in a home’s air and even interact with other substances to create indoor air pollution.
INDOOR AIR POLLUTION HEALTH RISKS
Many times, we aren’t even aware that our home is filled with indoor air pollution that is causing us health problems. We’ll have a cold that just won’t go away or sniffles that won’t stop. Maybe we’ll get itchy eyes, a scratchy throat, or even an unexplained rash. If it’s winter, we assume we need to increase our home humidity levels, and in the summer we think it’s allergies due to ragweed or something else outside.
But often, the cause of lingering health issues like respiratory problems, headaches, frequent colds and coughs, and even fatigue can be traced back to indoor air pollution. It can also cause cancer and chronic obstructive pulmonary disease (COPD). According to the World Health Organization, 4.3 million people die each year from the exposure to indoor air pollutants.
In short: your indoor air quality matters!
How to Improve the Indoor Air Quality of your Home
1. Air it out: Keeping your windows continually closed traps irritants indoors with you. When the temperatures are mild, open windows on opposite sides of your home to create a cross-draft that will quickly freshen your indoor air. If a family member suffers from outdoor allergies, do this during times pollen is lowest: immediately after a good rain, 2 hours after sunrise, or late at night.
2. Grow air-filtering houseplants. Some plants are excellent at removing pollutants from your home’s air. Boston ferms, palm trees, and rubber plants all improve indoor air quality, as does the easily grown and propagated golden pothos. (You can now order plants that clean the air from Amazon!)
3. Don’t just move dust around. Feather dusters don’t do a good job getting rid of fine particles. Although popular, Swiffer dusters are just a step better unless you spritz them with a little water, so they don’t shed matter as you walk through the room. Microfiber cloths with ultrafine fibers do the best job, especially if you use them damp and rinse them often. (Find more of my tips to reduce household dust here .)
4. Get your home tested for radon. It’s estimated that 1 in 15 U.S. homes has an elevated radon level. This naturally-occurring gas travels up through the soil into your home’s air, which is one reason it’s found primarily in basements. The leading cause of cancer in nonsmokers, radon is both invisible and odorless, making it essential to test your home at least once. You can find radon kits for as little as $15 at hardware stores or online.Improve your indoor air quality with these 11 easy tips!Click To Tweet
5. Choose your fabrics wisely. Silk and dry-clean-only fabrics may look lovely but, since they can’t be easily laundered, they also hold onto contaminants in our home’s air. Opt for washable fabrics, and clean your curtains seasonally. If you already have non-washable materials, be sure to vacuum them on a regular basis thoroughly.
6. Use the right vacuum, properly. Vacuums with bags do the best job trapping dust since they’re sealed. Can’t stand the thought of shelling out for new bags regularly? Go for a vacuum with a high-efficiency particulate air (HEPA) filter to get over 99% of the ultrafine particles that lead to health issues. (Here’s the one I love.) When you do use it, vacuum properly: slowly, making four passes (back and forth then back and forth), overlapping passes each time.
7. Abandon your aerosols. Cleaning and personal products that come in an aerosol can also contain a nasty secret: VOCs like butane and propane that act as propellants to deliver the product. Those spray cans of air freshener? They might leave your air smelling nice, but it’ll hardly be fresh. Switch to spray bottles when you can, and run products through The Good Guide to check their health safety.
8. Get a natural clean. Homemade cleaning products aren’t just economical, they’re better for your indoor air quality, too. Ditch the ammonia-based glass cleaners and make your own window spray for pennies. For more DIY products, check out my section on homemade cleaning products.
9. Filter your air. Make the most of your home’s HVAC system, if you have one, by changing your filter often — seasonally, if you don’t have pets or allergies, monthly if you do. While the cheaper ones do an adequate job removing ordinary dust from your home’s air, if you live in a high-pollution area you should consider springing for the ultrafine particle reduction HEPA filters.
10. Opt for fragrance-free. Scented products have a scary secret: they emit VOCs, including some that are classified as hazardous or toxic. This includes cleaning products like disinfectants and sprays, laundry detergents and fabric softeners, lotions, body washes, deodorants, and shampoos. According to an EPA fact-sheet (.pdf):
Fragrance-free means that fragrance materials or masking scents are not used in the product.
Unscented generally means that the product may contain chemicals that neutralize or mask the odors of other ingredients.
11. Literally, clean your air. If someone in your home has respiratory or allergy problems, consider investing in an air purifier to remove dust, pollen, and other particulate matter from the air. Be sure to check the packaging to make sure the Clean Air Delivery Rate (CADR) suits the room where you plan to use it, then maintain it according to the manufacturer’s recommendation, so you aren’t adding mold or mildew to your indoor air.
KEEP IT CLEAN
Don’t forget: regular, weekly cleaning of your home helps to remove dust and prevent mold and mildew. If you don’t have a routine already, check out this list of printable cleaning checklists to get started.
