When it comes to protecting your air conditioning system and ensuring the quality of your indoor air, the size of your filter matters.

How often you change your home air filters depends on the type of air filter you have in your home and on environmental conditions, such as smoke, dust, or construction. Turning the filter upside down can cause the filter to collapse and, therefore, air flow to circulate around it. It can be confusing to understand the most common air filter sizes if you're not sure what the numbers mean.
