When it comes to keeping your heating and cooling system running at its best, one of the most important things to consider is how often you should change your air filter. A three- to four-inch filter can last six to nine months, while a five- to six-inch coarse-grained filter can last nine to twelve months. However, if you have a lot of pets in your house or a smoker in your family, you may need to replace the filter more frequently than recommended. During the heating season, it's especially important to keep up with changes to the boiler's air filter.
This is because the filter is designed to trap dust and particles in the air as it passes through and enters the oven system. If you don't change the filter regularly, contaminants can reach the air in your home and cause improper filtration. If your house has a lot of dust, you'll need to change one-inch and two-inch filters every month, four-inch filters every two months, and five-inch filters every three months. Depending on your lifestyle and the type of oven filter you choose, you may want to change it more often.
If your furniture gets dirty soon after cleaning the house, it could be a sign that your oven filter is clogged and no longer effectively removes dust from the air. By ensuring that your filters are changed when needed, you can enjoy a heating and cooling system that will perform at its best. In summer and winter, homeowners usually change oven filters more frequently than in fall and spring. This is because during periods of the year when HVAC equipment is operating frequently, air circulates more times around the house compared to times when the HVAC system is used sparingly.
