Filters are an important part of your total home heating and cooling system. They play the crucial role of filtering out harmful particles like dust, pollen, pet dander and more so they don't circulate throughout your home. Filters also keep your system's internal parts clean from debris and build up so it runs more efficiently and lasts longer.
Return vents. Most homeowners are familiar with return vents. Many homes have several placed either on a wall or ceiling. Return vents help keep the air pressure consistent in your home and trap many particles so they don't circulate or enter into the HVAC system. The air filter is located directly behind the gate. It is common to change the air filter out from these every 90 days.
Your air conditioner or furnace will also have an air filter closer to the indoor mechanical system. Usually the air filter is near a return air duct or blower compartment. It may be tricky to find in some systems but here's a good place to start.
Typically, you'll want to change your filter every 90 days for the best air quality and efficiency. Timing may differ depending on the type of filter and whether it's attached to an air conditioner or furnace.
Locate all the filters in your home along with size. Most filters will include sizing information around the edge of the frame. Measure for length, width and thickness if the size isn't indicated and select your new filters. Be sure to place the filter correctly. Most have color or arrows to mark the front and back (upstream and downstream flow).
