Most 16x25x1 air filters need to be changed after two to three months, but the frequency of replacement depends on your lifestyle and use. Experts suggest changing fiberglass filters once every 30 days, while pleated filters can last up to three to six months. Generally, one-inch-thick oven filters should be replaced every one to two months. If you have young children in your home, it is recommended to change the air filter more often, once every 2 to 3 months.
Furnaces, the heating component of the central air system, are made up of several main parts that are responsible for heating the air inside the house. A house that is occupied most of the time will require more frequent use of the air conditioning system and, therefore, you will need to replace the filters much sooner compared to a house with no occupants. Air filters are electronic devices used in homes, offices or any enclosed space to regulate temperature, collect dirt and allergens, and control humidity. For example, the presence of pets and people with allergies requires an air filter with a higher MERV rating to collect more particulate matter.
Fiberglass air filters have low airflow resistance, making them popular in residential homes. You can easily check the size of your old filter on their site; the size is usually shown on the filter's cardboard frame. A typical 20x25x1 filter has almost 30% more surface area than a 16x25x1 one and, therefore, 30% more dust-holding capacity. On the other hand, smaller rooms won't require much air pumping, implying a lower frequency of filter replacement.
A 120 KBTu oven moves twice as much air as a 60 KBTu oven, which means the filter will get dirty twice as fast. Most filters come with a replacement recommendation (for example, every 3 months), but the actual lifespan of the filter will vary widely depending on the application. We also offer filters for 5-inch ovens (16x25x5 or 20x25x), whole-house air filter brands, and filters for rigid cell ovens. Also keep in mind that thicker oven filters tend to last longer, providing greater filtration over time, so they usually cost more than 1 or 2 oven filters.
The most important thing to remember about air filters is to change them regularly. It is generally recommended to change residential air filters every 30 days if regular fiberglass filters are used. When air filters don't change, dust, pollen, dirt, and other contaminants accumulate and decrease filter efficiency. In just over an hour, our technicians can do some magic to replace your 1-inch filter grille with an authentic air filter.
An Aprilaire filter has four-inch deep pleats to allow excellent air flow to the oven. With a dust holding capacity of more than a year, replacing the filter is actually cheaper and much less complicated than a monthly visit to the hardware store.
