Furnace & Air Conditioner Filters

Keeping your furnace and air conditioner filters clean and replacing them when necessary is an important way to keep your home in top notch condition. Filters bogged down with dust, lint, animal hair, and other common home particles can decrease the efficiency of your air system as well as a decrease in performance of filtering out contaminants from the air circulating in your home.
When looking to replace your filter its important that you are finding the correct size replacement and finding a filter that meets the filtration needs of your home (commonly measured in MPR or MERV for air filters). If you know the size of your filter and looking for more information about MERV ratings try checking out our Air Filters by Size page to find the filter that is right for you.
