Air Filters by Size

Whether you want to reduce pollen and pet dander or dust mites and bacteria, find the air filter right for your home. By trapping and removing unwanted air contaminants, you and your family can breathe easy. A clean air filter not only supports healthy living, but it reduces your home's energy cost.

Select the filter size needed for your furnace or air conditioner. If you're not sure what size filter you need, remove the existing filter and look on top of it. Its dimensions should be listed, and it's important to replace it with the exact same size filter.
