Furnace manufacturers say filters should be changed at least once a month.
Putting off changing the filters could result with the following problem.... If your furnace is newer they will shut down when it's lacking return air..... Well you will think something is wrong... call a service tech... he will come change your filter and hand you an expensive bill and will tell you to have a nice day.
At least check it once a month... If the thing doesn't have a bunch of crap on it it could probably go another month... But if you have pets, or burn candles(causes soot on the filter), I would change it once a month for sure.
