Need Help Finding the Right Fit?
- Your current filter (yeah, you're gonna want to get rid of that one) usually has the sizes listed on the side.
- If you currently use a 1" wide filter, order one of our 2-Ply Filters.
- In order to use our 3-Ply Filter, you MUST currently be using a 2" or wider filter.
- You CAN replace a 4"+ filter with our 1" filters (seems funny, yes, but it will 100% work).
