Carrier KFCEH1801F20 Air Filter
It is advised the your furnace filter is exchanged for a new one every 3 months for optimal air quality through the ducts. Exact measurements of the filter is not really a choice that needs to be made due to the requirement of your furnace or handler. All air filters exist in many different filtering levels, which depends on your particular desire for cleaner air and whether anyone suffers from allergies in the home.

- When you hold it up, the light will not shine on the opposite side of the dirt filled filter
