Ways to improve indoor air quality

It’s impossible to get completely clean air. Walking, cleaning, cooking can all add low levels of contaminants. But you can do multiple things, from structural to easy fixes, that can keep your indoor air safer. And while air purifiers seem like an obvious solution, their health benefits are widely overrated. At their best, they can modestly reduce allergy symptoms, but their efficacy for asthma attacks has less scientific support.
According to the EPA, by far the most effective method to minimize indoor air pollution is to control the sources of pollutants and to ventilate a home with clean outdoor air when possible.  Here are some of the EPA’s most viable strategies for caring for your indoor air.

Controlling the relative humidity level in a home can help minimize certain kinds of bacteria. Relative humidity of 30-50 percent is considered ideal for homes.  Make sure to clean your dehumidifier in accordance with the manufacturer’s instructions and refill with clean water daily. For sensitive people, studies do show a link between indoor dampness and some upper respiratory tract symptoms, coughing, wheezing, and asthma symptoms.
