Invest in a Good Air Filtration System
The Asthma and Allergy Foundation of America rates indoor air quality as one of the top five environmental health risks. So I recommend doing more than just opening the windows from time to time. Clear the air by adding a room air-purifier, or go one step further and install a central filtration system. Today’s models can remove particulates that can’t be seen by the naked eye, such as dust, pet dander, molds, spores, pollen, and chemical gases such as sulfuric acid, ammonia, and formaldehyde.
