How Often Should I Change My Air Filter?


If anyone in your home suffers from allergies, asthma, or a weak immune system, you probably already know how important indoor quality can be. Even if you already prioritize IAQ, you may have wondered to yourself “How often should I change my air filter?”

Our team of highly trained technicians at On Time Home Services has the info you need to determine when to change your air filter and some tricks to help you remember to do it on time.

How Often Should I Change My Air Filter?

The answer to this question can differ a little bit from household to household. We recommend that everyone change their air filter at least once every 90 days. This ensures that dust, pollen, and other debris won’t block airflow in your ductwork and reduce the efficiency of your whole HVAC system. Plus, it keeps the air that will end up in your lungs cleaner. Air filters remove airborne allergens and bacteria that can make you sick.

In households that are more prone to airborne pollutants and particles, we recommend changing the air filter every 30 days. You should change your air filter more frequently if:

  • You have lots of shedding pets
  • You are remodeling part of your house
  • Someone in your house smokes
  • Someone in your house is sick or has low immunity
  • Someone in your house suffers from asthma or allergy symptoms

Changing your air filter is inexpensive and easy to do. The more often you change it, the better for your indoor air.

Tips for Remembering to Change Your Air Filter

Do you intend to change your air filter regularly, but you always seem to forget about it? We can help with that! Here are a few handy tricks to help you remember to change your filter every 30 or 90 days.

1. Set an alarm on your smartphone.

Your HVAC system is calling! When you receive a notification every 1-3 months, you won’t be able to ignore your air quality.

2. Pencil it in your calendar.

If you prefer an old-fashioned day planner or wall calendar to a smartphone, just make a note in writing. The next time you change your filter, note it on your calendar and flip forward to remind yourself when you need to do it again.

3. Label your filters.

If you don’t use a smartphone or a planner, no worries. Next time you change your air filter, buy a larger pack with multiple replacements. Write the date that you plan to change the filter on the top of each one clearly. Leave a few blank just in case you need to change your filter more frequently in the future.
