A task we often forget: changing an air filter. This is one of the most important things you could do to take good care of your home and the air quality within it. Regularly replacing your air filter keeps your AC and HVAC systems working properly, and also helps to contribute to lower energy bills. How often should you be changing your air filter?
How Often Do You Need to Change Your Air Filter?
As a general recommendation, you should change your AC filter every 30 days. This applies to regular fiberglass filters. If you use a more costly filter, such as one with pleats, they could last as long as six months. These recommendations are based on the assumption that you’re running your AC similar to the national average.
At All Brands Corp. AC Inc., we suggest replacing your AC filter every 90 days. However, there are several factors that affect how often you should be changing it, like:
- How frequently you use your HVAC system
- The number of pets you have
- The type of air filter you have
- If you have allergies
- The number of occupants
- The level of air pollution and construction sites in the area
If you’re a single occupant with no pets or allergies, you can change your air filter every 6-12 months.
If you live in a family household with no pets, you can change your air filter every 90 days.
If you have a dog or a cat, you should be replacing your AC filter about every 60 days.
If you have more than one pet or if anyone in your household has allergies, we recommend replacing the air filter anytime between 20-45 days.

How to Change Your Air Filter
Before attempting to change your AC filter, you need to make sure you know the size to be able to purchase the right replacement filter. The filter size is usually indicated on the side of the filter. When in doubt, you can count on a reputable Florida Keys air conditioning specialist to help you.
- Turn off the power.
- Remove the old filter by sliding it out of its slot.
- If you’re using a disposable air filter with a cardboard frame, replace it by sliding in a new one.
- If you’re using a reusable filter with a sturdier frame, check the instructions on how to wash it. These are typically meant to be rinsed with water and laid out to dry.
