How to Choose an AC/Furnace Air Filter?


Find Your Filter Size

Check your furnace manual or check the current filter to get the correct measurements — the size is usually stated on the surface.


Pick Your Filter Type

Make sure you pick an air filter that can help with any ailments you have, such as allergies. After pick paper or fiberglass? Reusable or disposable? 


Choose Your MERV

MERV is a measurement of how well particles are filtered out in the air, how efficiently air flows, and how long the filter can last. The higher the value, the more particles it removes.
