Are you looking for the location of your air conditioner filter? You're in the right place! In this article, we'll provide a comprehensive guide to help you find the filter in your HVAC system. The filter in your HVAC system is essential for keeping your air clean and free of contaminants. It traps dust, pollen, and other particles that can cause allergies and other health problems. But where is it located? The answer depends on the type of HVAC system you have.
For central air systems, the filter normally slides in a slot above or below the HVAC unit. If you have a large system with multiple air handlers and return ducts, finding the filters can be a challenge. For any other type of system, look for the air cleaner behind the return air grille on the wall, ceiling, or utility closet door. Usually, the air cleaner is close to your home thermostat, in a return duct.
Or, it's most likely right next to the air handler for your air conditioning system. In some systems, filters are located in the return air duct. This is the one that draws air from your space and returns it to the air conditioner's air handling system. Once you have these numbers, head to your local hardware store and you'll find a wide variety of filters.
The air handler draws air from the home through the return duct system and then blows the air through the heating or cooling system and returns it to the house through the duct system. In this case, the air filter is most likely located right next to the boiler air controller or air conditioning system. Some manufacturers place it where it can also filter recirculated air, depending on the position of the recirculation door. The filter is installed so that the arrow (and airflow) shows air moving through the filter TO the duct system (on a central air return grill) or TO THE air handler (for filters installed in the blower unit).
According to a study by the Korean Institute of Industrial Technology, automotive cabin air filters trap 50-90% of particles larger than 0.3 microns, such as dust, soot, pollen and insects. If you want to improve the air quality in your space by eliminating pollen, mold, and other harmful contaminants, you should invest in HEPA filters with a MERV rating of 10 or higher. When you return home, simply slide the old filter out and place the new filter, facing the same direction as the one you removed. You may be able to see and access the filter without opening anything, or you may need to open a metal panel (marked FILTER) on the front or top of the blower.
Fortunately, inspecting and replacing the cabin filter doesn't require a lot of time and little tools, if any. We hope this guide has been helpful in finding your AC filter!
