How Often Should You Change Your Air Conditioner Filter? A Comprehensive Guide

It's essential to replace your home air filter every 3 months, or 90 days, to ensure maximum efficiency and clean air quality. However, if someone in your family has allergies or asthma, you should change the filter more frequently. Environmental conditions inside and outside your home can also influence how often you should switch the filter. Generally, recommendations range from every 30 days for cheaper fiberglass filters to 6 months for high-end pleated filters.When it comes to changing your air filter, it's essential to purchase the correct size and type.

Make sure to install the filter once you've bought it. If you're uncertain of how to do this, it's best to consult a professional. You can check your air filter once a month to see how dirty it is. If there is a visible layer of dirt that covers most of the surface of the filter and is thick enough to hide the filter material itself, it is a sign that the filter has been in the air conditioning system for too long.

This could also cause damage to the system, which would be much more expensive to repair than simply buying a new air filter. To ensure your air conditioning system runs efficiently and effectively, it's important to change your air filter regularly.
