It really depends on the house and personal preferences, but as a rule, because 20x25x5 air filters are stronger than most air filters, most homeowners only use two to three 20x25x5 air filters a year. It is important to remember to change them regularly, with residential air filters typically needing to be changed every 30 days when using normal fiberglass filters. When air filters are not changed, dust, pollen, dirt and other contaminants accumulate and lower filter efficiency. This means that during peak summer and winter months, air filters need to be changed more often than necessary during spring, autumn and milder months.
Rather than relying on a standard timeline, there are some special signs and considerations that will let you know when it is time to change an oven filter. Doing so allows the HVAC system to operate as efficiently as possible, reducing the cost of heating and cooling a home. Even if you live in a temperate climate with excellent air quality, there is another important reason to change your oven filter as recommended. Considering the factors that influence the air quality inside your home is a good measure of how often oven filters should be replaced.
Clogged filters not only adversely affect the air quality in a house, but also force the oven to work harder to draw air into the system and thus be able to shorten the life of the oven. As a general rule, you'll want to replace your home's pleated air filters and oven filters every 90 days. You may need to change your HVAC filter more often if you have allergies or asthmatics in your home. To check if it is time for a replacement, remove the air filter from the air conditioner and hold it up next to a light source; if you can't see the light through the filter, it's definitely time for a new one.
Be sure not to confuse Honeywell oven filters with your HEPA air filters for purifiers, which last much longer. Determining how often you need to change your air filter will depend on where you live, the time of year, the filter material, and the efficiency of the filter you select. During a remodeling project, change the furnace filter every 30 days, or even more frequently, to prevent building-related dust from circulating around the house. Some people live in climates where air cooling is needed almost all year round, which means that heating the house is not a concern.
Changing the oven filter regularly ensures that the air in your home remains free of dust and other contaminants.
