Having your air ducts cleaned is the most effective way to improve your indoor air quality but there are other steps that you can do at home to help maintain high quality air in your home.

By regularly changing out your filter, the filtration is more efficient and causes less strain on your system as well. If you have a permanent washable filter, make sure to rinse out that filter with a powerful water stream regularly. Take caution and double check that the filter is dry before putting back in furnace!

This will ensure that the air in your house is consistently running through the filtration system in your house. making the air cleaner. Another benefit to keeping the fan on is that the temperature will be more consistent and evenly distributed throughout the home. No more hot or cold spots!
