How Often to Change Home Air Filters
It is a general recommendation that you should change your air filter in your home every 30 days when using less expensive fiberglass filters. High-end pleated filters can last as long as 6 months, but these typical guidelines assume average use and don’t take into account the size and type of filter.
As a general rule, you’ll want to replace pleated air filters and furnace filters in your home every 90 days. The longer the filter is in place, the more dirt, dust and allergens are trapped clogging the filter and decreasing their efficiency. If you answer yes to any of the questions below, you’ll want to replace your filter more often than may be recommended. Find out below if perhaps you should be replacing your filter more often than you may think.
Does anyone in your house have allergies and/or asthma?
According to the Allergy and Asthma Foundation of America (AAFA), “indoor air quality is just as important as outdoor air quality. Outdoor air can contain harmful pollution. But indoor air can actually be worse than outdoor air.” If there is an asthmatic or allergy sufferer in your home, they are much more sensitive to airborne particulates than those that don’t suffer. If you answer yes to this question, you’ll want to change your filter every 6 weeks to keep your indoor air quality at its best.
Do you have any pets?
If you are a cat or dog owner you know all too well that odor can build up after time and that shedding is at its worst during the change of seasons. If you’re a pet owner, you’ll want to change your air filter every 2 months, especially when winter turns to spring and summer turns to fall.
Do you have younger children?
When you have young children in your home, you want to keep your indoor air quality at its best. To keep your air quality under control and your home clean, you’ll want to replace your filter at a minimal interval of every 2-3 months.
