Most 16x25x1 furnace filters need to be changed every two to three months, but this can vary depending on your lifestyle and usage. If the filter is made of fiberglass, it should be replaced every 30 days. Pleated filters, which are more expensive, can last three to six months. Nearly all 1-inch furnace filters should be changed in 30 to 90 days.
Changing the filter at the right time is essential for maintaining good indoor air quality and avoiding allergy symptoms, as well as preventing premature HVAC system failure. The general consensus among HVAC professionals is that you should replace your filter every 90 days or every three months. However, this depends on the thickness of the filter. Thicker filters have more space to collect dirt and dust, so they don't need to be changed as often.
Thomas Galbraith Heating, Cooling and Plumbing of Ohio recommends changing filters that are less than 2 inches thick every 30 to 90 days. Three- or 4-inch filters can last 6 to 9 months, and filters up to 6 inches thick can be replaced once a year. In most cases, one-inch-thick furnace filters need to be replaced every one to two months, regardless of what the packaging says. In just over an hour, our technicians can replace your 1-inch filter grid with an authentic air filter.
An Aprilaire filter has four-inch-deep folds to allow a large flow of air to the boiler. With a dust holding capacity of more than a year, replacing the filter is actually cheaper and much less complicated than going to a hardware store once a month. Because filters with higher MERV ratings are denser, the furnace must work harder to suck air through them, and not every furnace is powerful enough to do so. Clogged filters not only have a negative impact on a home's air quality, but they also force the boiler to work harder to draw air into the system, which can shorten the boiler's lifespan.
The Home Depot states that the air quality in your area can affect how often you need to change your boiler filter. If your furniture gets dirty soon after cleaning the house, it could mean that your boiler filter is clogged and not effectively removing dust from the air. For example, if you have pets or allergy sufferers in your home, you will need an air filter with a higher MERV rating in order to collect more particles. Additionally, if your home is occupied most of the time, you will need to replace your filter more often than if it were unoccupied.
I recently checked my filter and found it covered in dust, so I changed it for a new one and noticed that my indoor air was much cooler afterwards. Therefore, there is no clear answer as to how long an air filter can work efficiently before needing a replacement. If you have a pet, Service Experts Heating & Air Conditioning of Texas recommends changing filters by 1 to 3 inches every two months. If you have young children at home, you will have to change the air filter more often - once every 2 to 3 months.
Oven filters are always installed on the return side of the air controller, so the arrow must point towards the rest of the oven (or towards the evaporator coil). A typical 20 x 25 x 1 filter has almost 30% more surface area than a 16 x 25 x 1 filter and therefore has 30% more dust holding capacity. The filters are designed to trap dust and airborne particles as air passes through the filter and enters the furnace system. A clean filter is necessary in order to prevent dust from passing through the air conditioning system and accumulating in its inner coils.
Invented in 1902 by Willis Carrier, air filters work by transferring unwanted components of the air from indoor to outdoor spaces.
