Many homes have several appliances and systems that use air filters. The largest is a heating, ventilation, and air conditioning system (HVAC). Individual room heating and air systems, window air conditioners, air purifiers, humidifiers, dehumidifiers, oil diffusers, range hoods, clothes dryers, and vacuums have air filters that should be cleaned or changed regularly.
How Often to Clean Air Filters
Air filters should be cleaned or replaced on a routine schedule. Most HVAC filters should be cleaned or changed every two to three months. More frequent cleaning is needed if you live in an area with lots of dust or in a home with lots of pet hair or if you don’t clean regularly. An easy way to tell if an air filter in any system or appliance needs cleaning is to remove it from its usual location. Hold the filter up to a bright light or window. If you can see light coming through, it can be used for a bit longer. If no light comes through, clean the filter, or replace it.
Should You Clean or Replace Your Air Filter?
Some dirty air filters can be easily cleaned and returned to the appliance, others will not stand up to cleaning and must be replaced with a new filter. How do you decide? Disposable filters are designed for one-time use and are less expensive than washable filters. The frame is usually made of cardboard that will not stand up to cleaning. Attempting to clean a disposable filter can cause matting of the fibers, encouraging mold and mildew to grow and reduce the effectiveness of the appliance. Washable filters have metal or plastic frames and are more environmentally-friendly, but take more effort to maintain. One way to determine what type of filter you have or can use is to consult the appliance manual. There you will find instructions on how to clean or replace the filters, as well as a suggested schedule for changing or replacing filters so the appliance maintains its optimum performance. If you have lost the manual, consult the manufacturer’s website.
