Keeping your furnace air filter in top condition is essential for maintaining a healthy home environment. Depending on the type of filter you use, the frequency of replacement can vary from one to three months for a one-inch filter, up to nine to twelve months for a five to six inch filter. Pleated filters are more expensive but can last up to six months. If you have pets, young children, or people with allergies in your home, you should change the filter more often.
Honeywell filters have the same replacement recommendations as standard filters. Open windows and doors can also allow dust and outdoor air contaminants to accumulate in the home, so it's important to keep them closed as much as possible. The primary purpose of an oven filter is not to clean the air you breathe, but to clean the air that passes through the oven and other HVAC equipment. Smaller rooms won't require pumping a lot of air, so you can get away with changing the filter less often.
However, if you don't follow the right filter replacement program, your oven will stop working properly due to dirt buildup. To ensure that your furnace air filter lasts as long as possible, it's important to follow the manufacturer's instructions for changing it regularly. Additionally, keeping windows and doors closed as much as possible and using pleated filters if you have pets or people with allergies in your home can help maximize its lifespan.
