For optimal air quality and efficient operation of your furnace, it is important to change your furnace filter regularly. The frequency of replacement depends on the type of filter you have, the size of the filter, and the environment in which you live. For 3 to 4 inch filters, replace them every 6 to 9 months. For filters from 5 to 6 inches, replace them every 9 to 12 months.
Thinner filters, such as the traditional disposable model (1 inch thick) should be replaced at least every two months. Coarser filters are designed to be more efficient because the thicker the material, the more debris you can filter out of your home's air ducts. Even coarse filters need to be replaced every 6 to 12 months. If you don't seem to remember to do it, a good rule of thumb is to change your oven filter every time the seasons change.
During the winter, when the oven is used more often, you will have to replace the oven filter more often. If the outside temperature is extremely cold or hot and the boiler or air conditioner is running non-stop to keep up, filters that should have lasted 90 days will need to be changed every 30 days to ensure that your HVAC system is working properly. It consists of loosening the screws that hold the filter cover in place if it is behind a return air vent or simply pulling the filter out of a slot if it is on the side of the oven. The oven filter is used to clean the air of contaminants and dust just before the air enters the oven system.
If you don't change your air filter regularly, you don't allow it to serve its intended purpose of purifying the air in your home. If your furniture becomes dusty soon after cleaning the house, the oven filter could be clogged and no longer effectively removes dust from the air. On the other hand, if you use your HVAC system almost constantly, the filter will need to be changed every few weeks (especially if you use fiberglass filters). Just be careful not to confuse Honeywell oven filters with your HEPA air filters for purifiers, which last much longer. For optimal performance and clean air in your home, it is important to change your furnace filter regularly.
The frequency of replacement depends on several factors such as type of filter, size of filter and environment in which you live. For 3- and 4-inch filters, plan to replace them every six to nine months. If you have larger filters that are 5 or 6 inches, you will need to replace them every 9 to 12 months. Thinner filters should be replaced at least every two months while coarser filters should be replaced every 6-12 months.
