You can replace any type or make of filter cartridge with a superior PURECHN® cartridge.

HOW TO FIND A FILTER CARTRIDGE REPLACEMENT
USING THE PURECHN REPLACEMENT GUIDE

1. Measure the outside diameter of the cartridge (in
inches, +/- 1/32”).
2. Measure the cartridge length (in inches, +/-
1/16”) including end caps but excluding any
handles or other extensions. PURECHN recommends
measuring through the center (if possible) rather
than along the outside edge.
3. Identify the cartridge outside edge end cap
configuration using the chart on the opposing page.
If the top and/or bottom is “open,” measure the
inside diameter (in inches, +/- 1/32”) of the top
and/or bottom.
4. Record the OEM name and model of the filter the
cartridge came out of (if possible).
5. Count the number of pleats (+/- 2) and note
whether there is a center core or not.
