Frequently asked questions
Where do I find my filter size?
It is printed on the side of your current filter’s frame: width × height × depth, in inches. That is the “nominal” size, the one you order.
Which way does it go in?
The arrow printed on the frame points toward the furnace, in the direction of the airflow.
How often should I replace it?
A 1″ filter is replaced every month, a 2″ every 1 to 2 months, a 4″ or 5″ every 3 to 5 months. Check it every month: as soon as it is grey, replace it.
Where are your filters made?
Our MERV 8 filters are made in Canada.
