Replacing your HVAC filters should be easy. By following our simple instructions, you should be on your way to cleaner air and a happier, healthier home.
Step 1: Determine how often you should be replacing your HVAC air filters. If your filter is made of fiberglass, you will have to switch it out at least once a month. Thicker, pleated filters need to be replaced less
often. However, when you add pets into the mix, or it is a peak summer or winter month, the frequency of replacement increases back to once a month.
Step 2: Measure your current HVAC air filter. Before your filter is too dirty, remove it from your furnace or AC unit. Then, take a look at our comprehensive instructions.
Step 3: Dispose of your dirty filter. Unless you have a washable HVAC filter, you are going to need to dispose
of your old model safely and properly. Make sure you have a plastic bag large enough to hold the filter before removing it from your AC unit or furnace. Read our filter disposal guide for more
Step 4: Install your filter. With the airflow arrow pointed towards the blower, insert your HVAC filter inside your furnace or AC system.
