In a central air conditioning system, the air in the house is circulated through the ducts over and over again. If the ducts are not clean, the air can become stained with pollutants, making it unhealthy to breathe. Here are three ways to keep the air clean.
- Change your air filter. Air filters that have been in use for a long time can bring in a lot of dust and bacteria and need to be replaced promptly.
2. Clean the air ducts with a rotating brush.
3. Seal your air vents with a magnetic lid, clear lid, or plastic cover when not in use.
