Home air filter guide
How often should you change your home air filter?
There is no single replacement schedule that is right for every home. How often you need to change your air filter can depend on the filter, your home, and how your heating and cooling system is used.
The short answer: check your filter regularly
Air filters are not all the same, and homes do not all create the same conditions. Because of that, it is best to follow the recommendations provided for your specific HVAC system and air filter.
A useful habit is to check your filter regularly and replace it when needed based on its condition and the guidance provided by the manufacturer.
The important challenge for many homeowners is not changing the filter itself. It is remembering when enough time has passed to check it again.
What can affect how often you change an air filter?
Your filter type
Different filters can have different intended replacement or maintenance schedules.
How often your system runs
A system that runs frequently may move more air through its filter over time.
Your home environment
Conditions inside and around a home can affect how much dust and other material reaches the filter.
Pets and household activity
More activity and pet hair can be additional factors to consider when checking your filter.
Remembering the next check
The replacement schedule only helps if you remember it.
After changing an air filter, it is easy to assume you will remember the date. A few weeks or months later, however, that date can become difficult to recall.
You can use a calendar, phone reminder, written note, or a dedicated physical reminder to help keep track of the next time you should check your filter.
A simple reminder
Let Baby Bird help you remember.
Baby Bird is being designed as a dedicated home air filter reminder. After changing your filter, you reset Baby Bird and let it keep track of time for you.
When it is time for your next reminder, Baby Bird is designed to glow and chirp—without requiring an app, Wi-Fi connection, account, or subscription.
Baby Bird is currently in development. No payment is required to reserve your place, and final product specifications may change.
