Here are some pointers on how to clean the air in your house safely.
Open your windows for as little as five minutes every day to help reduce the buildup of dangerous air pollutants in your indoor air.
Keep pet dander to a minimum by washing them regularly, brushing them outside if possible and vacuuming floors and furniture using a HEPA filter on a regular basis.
Run your AC! You already have a whole-house air filtering system if you have central air conditioning. Most systems contain a filter that must be changed on a regular basis, and this filter will trap irritants while the AC runs.
