How Often Should I Replace my Furnace Filter?

In general, you should replace your disposable filters at least once a month. We recommend that you visually check filters and filtering equipment monthly. If filters look dirty, they need to be cleaned or replaced. If you have washable filters, they can be rinsed off. Replacing your filters on a regular basis ensures optimum efficiency and filtration for your system.
