How to Avoid In-Home Air Pollution
Did you know that indoor air quality can be worse than the air outdoors? Unlike outside, where wide open spaces and continuous breezes tend to diffuse pollution, the inside of a home is a closed-in space that gathers pollutants and holds them in. Even when you open your windows and have a well-ventilated home, pollutants tend to linger and, over time, can cause respiratory problems. These pollutants can include anything from dust to lead, to radon, to ordinary smog—none of which are things that you want to be breathing in large quantities.
Here are five things you can do to get rid of air pollution in the home.
1. Keep your floors clean. Floors tend to accumulate much of the dust that can rise into the air and present a threat of respiratory problems. In both hardwood floor and carpet, pollutants can build up not only on the surface but also below the carpet or floorboards. Be sure to keep the floors as fresh as possible, cleaning once a week, and consider having old carpet or hardwood flooring replaced every few years. Do keep a mat at the front door so that there’s less chance of tracking in dust.
2. Do a radon test. Radon is a colorless, odorless gas that has been shown to increase the risk of lung cancer. There are radon tests that you can purchase and perform at home, or you can hire a professional to do the test for you. In either case, if you find that you have an above-normal level of radon in your home, do take measures to get rid of it.
3. Don’t smoke indoors. A common misconception about second-hand smoke is that it’s only present when someone is actually smoking. But the reality is that all those chemicals that make smoking so dangerous get into the walls, floors, and furniture and can continue to cause harm even when no one is smoking.
4. Dehumidify. Things like molds and dust mites like to build up in areas where there is a high level of moisture. It’s a good idea to keep the humidity in your home around 30-50%. Here’s how you can accomplish that:
-use a dehumidifier;
-don’t give your houseplants too much water;
-crack a window or use an exhaust fan when showering, cooking, or washing dishes;
-fix any leaky plumbing in your home.
5. Use natural products: Chemicals in things like laundry products, dish soaps, and air fresheners can send lots of chemicals into the air. If you’re using any of these things, switch to mild, fragrance-free varieties made of natural ingredients.
