Your air filter is an important part of your HVAC system, helping to keep dust, dirt, pollen, and other airborne particles out of your home. But how often should you replace it? The answer depends on several factors.

What Factors Determine How Often You Should Change Your Air Filter?

The frequency with which you need to change your air filter will depend on a few things, such as:

The size of your house: Generally, the bigger the house is, the more often you'll need to change the air filter. This is because larger homes tend to accumulate more dust and dirt.

The type of filter: Different types of filters have different lifespans. For instance, standard fiberglass filters last for about one month while pleated filters can last up to three months.

The environment: If you live in an area with a lot of dust or other airborne particles, you'll need to change your air filter more often.
