Discount Filters offers a wide range of air filters at a discount to help you breathe better air inside your home. Whether you need to replace the wrong size filter or just want to maintain superior indoor air quality, Discount Filters has you covered. A dirty filter restricts air flow to your HVAC system's air controller, making it work harder to cool or heat your home. To keep your filter in good condition, avoid using oils, adhesives, household cleaners, industrial cleaners, or alkaline solutions as they could damage the filter.
If you have pets, children, or people with allergies in your home or business, it is recommended to replace filters more frequently. When creating a filter with this tool, make sure to use the “real” filter size shown by the measuring tape and not a nominal filter size. The filter frames are made of beverage cardboard which stays strong despite humidity and temperatures of up to 200° F.
