A general rule for pleated air filters (such as those manufactured by FilterBuy) is to change them every 90 days. As the filter traps more dirt, dust and allergens from the air, its efficiency decreases. Some Air Bear oven filters can last six to nine months before they need to be replaced. At Filterbuy, we recommend replacing air filters at least every 90 days or 3 months, especially for heating and cooling equipment.
However, in some cases, it might make more sense to change them sooner rather than later, so checking the oven filter should be a monthly maintenance measure. Our MERV 3 air filters of 1, 2 and 4 are designed to last approximately 3 months, while our MERV 13 replacement filters for the whole house must be replaced every 6 months. If you have pets, children or people with allergies in your space, we recommend that you change the filters more frequently. It's important to replace filters regularly, because the older an air filter is, the less bacteria and dirt it removes from the air, which will worsen indoor air quality and increase energy costs. The general guidelines for how often to change an air cleaner in an apartment are the same for a single-family home or a townhouse.
Most air filters last between 1 and 3 months. You can already hear it: your HVAC technician is giving you lessons on how to make sure you change your air filter. How many days were it again? 30? 100? — The general consensus is that you should replace your home air filter every 3 months or 90 days. But what happens if you let that time go by a little? Before we talk about WHEN you should change your air filter, let's start with the WHY. Their specific situation is unique, but most air filtration experts agree that oven filters have an overall lifespan.
Air filters with higher MERV values can purify the air of more pollutants in the air, but the tradeoff is lower air flow due to the greater resistance of the air filter. Options such as 6-stage electrostatic air filters (available on Amazon) can be rinsed with a garden hose as needed and reused for several years if properly maintained. As air moves through a building's air conditioning system, air filters trap and accumulate large and small particles, such as dust, allergens and microorganisms. Using an air filter with a MERV rating higher than that recommended by the boiler or air conditioner manufacturer may affect its performance. Because the air in the apartment circulates more air through a greater variety of units, your apartment's air cleaner may get dirty faster than one in the house. If you only have one smoker in the house, you can get away with changing a one-inch or two-inch filter every two months, a four-inch filter every four months, and a five-inch filter every six months.
If your house has a lot of dust, you'll need to change the one-inch and two-inch filters every month, the four-inch filters every two months, and the five-inch filters every three months. Varieties such as FilterBuy's MERV 8 air filters (available on Amazon) are slightly more expensive, but will last from four months to a year. If windows and doors are often left open, one-inch and two-inch filters will need to be replaced monthly, four-inch filters every two months, and five-inch filters every three months. Even if you live in a temperate climate with excellent air quality, there's another important reason to change your oven filter as recommended. These filters, like the E-Z Flow air filters (available on Amazon), are designed to be discarded after one to two months. Considering the factors that influence the air quality inside your home is a good measure of how often boiler filters should be replaced.
