Studies have tied poor outdoor air quality to lung cancer, strokes and heart disease. In fact, air pollution causes about seven million deaths worldwide each year, according to the World Health Organization. However, the air inside your home is typically even more polluted than the air outside, the Environmental Protection Agency (EPA) says. And research shows we spend most of our time indoors, which is all the more reason to start cleaning our indoor air. There is a myriad of reasons your indoor air can be polluted. Some sources, such as furnishings and building materials, can release pollutants more or less continuously, according to the EPA. Other sources, like smoking, cleaning or renovating, can release pollutants intermittently. Unvented or malfunctioning appliances can release potentially dangerous levels of pollutants indoors (which is why it’s so important to have a working carbon monoxide detector in your home). And if you think spraying scented air freshener will clean your air, think again. That scent is also a form of indoor air pollution, and most air fresheners just release more potentially harmful chemicals into your home. The health issues caused by those chemicals cost about $340 billion a year in treatment and lost productivity expenses, according to a study published in The Lancet. Read on for some tips on improving your indoor air quality without the use of chemicals. 1. Open Your Windows Treehugger / Sanja Kostic It's the simplest (and cheapest!) thing you can do to improve your indoor air quality. Open your windows for even just five minutes a day to alleviate the accumulation of harmful air pollutants in your indoor air. 2. Spruce Up Your Décor With Houseplants Treehugger / Sanja Kostic Several types of houseplants filter out common volatile organic compounds from your indoor air. Having indoor houseplants can help improve indoor air quality, according to a study published by the American Society for Horticultural Science. For example, spider plants are effective at reducing benzene, formaldehyde, carbon monoxide and nitrogen dioxide. (Here are more houseplant suggestions.) 3. Opt for Essential Oil Diffusers Treehugger / Sanja Kostic Some essential oils, like tea tree oil, have antibacterial properties and can be added to homemade household cleaners or even applied topically to your skin to treat a small cut. But did you know these oils also can reduce airborne bacteria? Essential oils like eucalyptus, clove and lavender have been proven to help reduce the number of dust mites in your house, too. 4. Opt for Beeswax Candles Treehugger / Sanja Kostic Bear with me on this one, because it’ll get a little scientific. The reason particles float in the air around us is because they are positively charged ions. The air is cleaner in the woods, or near a lake, for example, because nature creates negative ions, which bind to the positive ions, causing them to be heavier and fall to the ground. Burning pure beeswax candles artificially creates this phenomenon indoors, cleaning the indoor air. However, burning any kind of candle still sends soot up into your air. To avoid that completely, consider LED candles, which will pollute the air less and reduce the risk of a fire. 5. Take Your Shoes Off Treehugger / Sanja Kostic The dirt outside can carry some really yucky stuff: pesticides, pollen, fungi, bacteria or feces, for example. When you walk inside your house, any or all of that could be on the bottom of your shoes, so it’s best to take them off when you get inside. It’ll help keep your air cleaner — not to mention your floors. 6. Keep Your Pets Groomed Treehugger / Sanja Kostic Pet dander — your pets' skin cells — is found nearly everywhere in a home with pets. Even more than pet fur, dander can cause you to develop asthma-like symptoms or exacerbate your asthma if it already exists. If you have a pet, be sure to keep dander to a minimum by cleaning them regularly, brushing them outdoors if you can and vacuuming floors and furnishings regularly with a HEPA filter. 7. Run the AC Treehugger / Sanja Kostic If you have central air conditioning, you already have a whole-house air filtration system at your disposal. It works by pulling air out of your house, cooling it and pumping it back in. Most systems have a filter that you need to change regularly, and this filter can trap particles while it does its job. The more you change it, the better. Find out what kind of AC system you have and what its manufacturer recommendations are for changing your filters. 8. Clean With Non-toxic Chemicals Treehugger / Sanja Kostic Many store-bought household cleaners contain toxic chemicals that can cause eye, nose, throat and lung irritation. If you’re going to use these, at least open windows while you do. But as a greener option, consider making your own household cleaners using ingredients such as vinegar, baking soda, citrus juice or essential oils. Here are a few green cleaner recipes to get you started. 9. Use an Air Purifier Air purifiers can be an effective way to reduce harmful particles in the air. If your child has asthma, it may be worthwhile to have one in his room. Find out which one is right for you using the EPA’s guide. 10. Get Rid of Mold This fungus releases spores into the air that can trigger allergy symptoms. It likes to grow in dark, damp places, such as your bathroom, laundry room and basement. But you don’t need to bleach it away. Here are five ways to kill mold without chemicals. 11. Air Out New Furniture Treehugger / Sanja Kostic Volatile organic compounds (VOCs) are chemicals that linger in the air, and they are everywhere in our homes. VOCs such as toluene and benzene are found in things like glues, paints, fabrics, construction materials and more. When you buy a new sofa or armchair, know this: It will emit VOCs, more heavily at first and then taper off. To reduce the harm to your indoor air, air out as much as possible to allow VOCs to escape. If you can, keep it in your garage for a week, or at least keep the windows in that room open most of the day for the first few months. 12. Use Cooking Oils With Higher Smoke Points Treehugger / Sanja Kostic To avoid a kitchen filled with smoke and a lingering smell of burnt oil wafting through your house for hours, use a cooking oil that smokes at higher temperatures. Extra virgin olive oil has a lower smoke point compared to avocado, peanut, safflower, canola, corn and sunflower oil. If you prefer the taste of olive oil, you can use light olive oil, which has been refined and has a smoke point of 486 degrees Fahrenheit compared to 410 degrees for extra virgin olive oil.
