Answer: There are three factors that decide whether a filter requires to be changed. Furnace filter are of two types- 1-inch filter and 3-inch filter. The former needs to be changed every month. The latter can be swapped after every three months. But the recommendation of the manufacturer needs to be seen. If you have pets in the house, you should change the filter more often due to the pet dander. If someone in the family is allergic to dust, the filter requires frequent changing.
