How often does a furnace filter need to be changed? Are there different lifespan of filters and what is the best brand for filters?
Depending on your furnace and also which filter you want, you can get filters that will last you 30, 60, 90 days and some of them can even last you forever those are called washable filter i think so you can actually reuse them, so its all based on how much you want to spend on your filters. Ask home depot workers they will help you choose a good one, and you gotta change them constantly if you got a regular filter
You gotta change your furnace constantly if you want your furnace to last longer, i agree with JJCool1 that you need to figuire out how long you want your filter to last
