How Often Should You Change Your Oven Filter?

Change your oven filters regularly to keep your home clean and air quality under control. As a general rule, most filters should be replaced every 3 to 6 months. Thicker filters may last longer than thinner filters. Here's a rough estimate of how long one can last, depending on its thickness.

A one-inch oven filter should be changed every one to three months, while a three- to four-inch filter can last six to nine months. A five- to six-inch coarse-grained filter can last nine to twelve months. Always follow the manufacturer's recommendations on how often you should replace filters. For more information on oven filters, contact the professionals at Harwich Port Heating and Cooling.

If you don't change your oven filter regularly, you may end up with an oven that doesn't work as efficiently and is likely to have a shorter lifespan. However, the smaller the appliance used to cool the small space, they often come with smaller filters, so you may have to change the filter as often as a filter in a larger house. To give you a starting point on how often you're looking to change oven filters, size matters. In winter, as long as the oven filter is not dirty or clogged, you can use the recommended 90 days before needing a replacement.

Use a filter with a MERV rating of 12, such as the Nordic Pure Filter (available on Amazon), if your oven can handle it. If someone in your household has allergies, you'll benefit from more frequent air filter changes. No two houses are the same, so despite guidelines, you may have to change your boiler filter more often than your neighbor.
