A good rule of thumb is to change 1-inch to 2-inch filters every three months, 4-inch filters every six months, and 5-inch filters every 12 months. Certainly, if you can't see the filter material itself, it must be replaced. Depending on your lifestyle and the type of oven filter you choose, you may want to change it more often. A number of factors must be considered when deciding how often an oven filter should be changed, and many filter manufacturers recommend how often their product should be replaced.
For 3- and 4-inch filters, plan to replace them approximately every six to nine months. If you have filters larger than 5 or 6 inches, you'll need to change them every nine to 12 months. You must change the filter at least every 90 days. In summer and winter, homeowners usually change oven filters more frequently than in fall and spring.
However, people in the north whose ovens don't have a break for months may want to change the filter every 30 to 60 days, as more air passes through the filter and it will clog up more quickly. 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 to fall. For every furry family member who lives in your home, the lifespan of the filter is reduced by approximately 30 days, so you change your oven filters more often. Oven filters should be changed regularly depending on their size and type.
Generally speaking, 1-inch to 2-inch filters should be changed every three months, 4-inch filters every six months, and 5-inch filters every 12 months. However, if you have pets or live in an area with extreme weather conditions, you may need to replace your filter more frequently. At the peak of summer and winter, air filters need to be changed more often than necessary during spring, fall, and milder months. When determining how often you should change your oven filter, you should first know what type of filter you currently have installed.
Filters with more folds such as the Honeywell Ultra Efficiency filter can trap more dust and require fewer changes - usually every 90 days - while other types may need to be changed monthly or even weekly. To ensure that your oven works efficiently and that your family is breathing clean air free from contaminants that can cause allergies or other health issues, it's important to keep up with regular filter changes. By following these guidelines and taking into account factors such as pet ownership or extreme weather conditions in your area, you can ensure that your oven filter is always working at its best.
