Honeywell recommends replacing the air filter every 6 months to one year depending on usage. On average, most 20x25x4 air filters last between six and eight months, meaning the average homeowner won't need more than two in a given year. However, if your heater fan is constantly running, you'll need to change the filter every month. If you have pets that shed a lot of hair, it's a good idea to take them outside to brush them regularly to reduce the amount of hair and dander that reaches your home.
During HVAC maintenance, specialists come prepared with precision tools to clean and service sensitive parts of the oven and air conditioning. The MERV 11 rating of the 20x25x4 air filter effectively reduces pollen, dust, pet dander, mold spores, dust mites and other indoor air allergens. Each household has different needs when it comes to their HVAC unit and the amount of dirt, dust, pet dander, and allergens in the air. We service, repair and install all types and brands of heaters and air conditioners along with drain cleaning.
Some homeowners choose to resize their oven to fit these filters for better filtration. If you have multiple animals in your home, you'll need to change a one or two inch filter every month, a four inch filter every two months, and a five inch filter every three months. If your house has a lot of dust, you'll need to change the one- and two-inch filters every month, the four-inch filters every two months, and the five-inch filters every three months.

Heating and air conditioning specialists recommend HVAC maintenance at least twice a year in addition to regularly changing dirty 20x25x4 air filters. With a clean air filter of 20x25x4, homeowners can prevent more particles from entering the oven. If your windows and doors are often left open, one- and two-inch filters will need to be replaced every month, four-inch filters every two months, and five-inch filters every three months.
