* Open windows and doors when possible. Introducing outdoor air into a home is a great way to improve indoor air quality. Of course, opening windows and doors might not be feasible in the middle of winter. But take advantage of any such opportunities when they present themselves. For example, after cooking a big meal, open the kitchen exhaust fan to allow fresh air into the home. Such fans are not large enough to cause a significant temperature drop in the home, but they can directly remove contaminants from inside the home, like those that might be emitted from gas stoves.
* Insist guests and residents remove their shoes. Chemicals can find their way into a home in a variety of ways, and you and your fellow residents or guests may be tracking them into your home on your shoes. Keep a doormat inside all entryways, and insist guests and residents remove their shoes before entering your home. This reduces the amount of potential pollutants brought into your home and also makes cleaning the home that much easier.
* Break out the mop. Vacuum cleaners can be effective at picking up pollutants inside a home, but they also can leave things behind. When a vacuum cleaner seems to be leaving some dust behind, take out the mop and, with just a little water, address the areas where dust is still lingering. Water should be enough to do the trick, and, unlike some cleaning products, water won’t be introducing any additional harmful pollutants into the home.
* Smoke outside. Smoking inside a home is inviting trouble, especially during those times of year when the windows cannot be opened. Secondhand smoke is a significant source of indoor air pollution, as cigarette smoke is known to contain more than 4,000 chemicals. Smoking indoors, whether an area is well- or poorly-ventilated, can be dangerous to smokers. Exposure to secondhand smoke puts adults and children alike at risk of several diseases, including asthma and cancer. If you or your fellow residents or visitors must smoke, do so outdoors.
