|How often should I change vacuum cleaner filters? |
In general, plan to change foam, cloth or paper pre-filters and exhaust filters every three months. Change them more often if your home is large or has new carpet, if you have children, if there is a lot of foot traffic in your house or if you have pets.
HEPA filters need to be changed (or cleaned, if washable) every six to twelve months. If you cannot see light through the filter when holding it near a light source, change it immediately.
Filters are either disposable, washable or vacuumable. You should follow the manufacturers' guidelines on how often to change, wash or vacuum the filter in your particular vacuum cleaner. Note that cleaning a washable filter requires you to handle the dirty filter - exposing you to dirt and any captured allergens. A disposable filter results in much less exposure since you just place it in the trash.
What happens if I don't change the filters?
Vacuum cleaners will lose suction power and eventually stop picking up dirt when the filters are dirty. Some poorly designed motor filters let air bypass the filter when they are dirty. This can damage the vacuum cleaner's suction motor and result in an expensive repair.
In addition, a clogged output filter (alternatively known as exhaust filter or after filter or final filter) increases strain on the suction motor. This can result in poor suction performance and reduced motor lifespan.
