Sizing/Compatibility

OrcaFilters are designed to replace the standard cartridge filters that are used in many small portable pool pumps.  These cartridge filters are reasonably standard among product families but there can be significant differences. This page will help ensure an OrcaFilter is a suitable replacement.

There are some pumps houses that the OrcaFilter will not work in - check the bottom of the table below for known incompatibilities.  

There are basically 3 critical dimensions in a filter cartridge; The length of the filter, the outside diameter of the filter end-cap and the inside diameter of the endcap.  

  

If you think your filter is non-standard, you can contact us and we will help you make sure an OrcaFilter is the right product.

For Intex and Unicel filter sizes these measurements are as follows:

A/C

The only difference between a type A and Type C is the internal diameter of the filter. The A/C Filter type is a hybrid which has an internal rim with a 1-3/4" internal diameter which will deform to 2" if the pump really needs an A filter. 

If your pump says it uses an A/C filter then you need to look at the pump itself and determine if the 1-3/4" internal diameter is critical. If it is, order a C filter from us. If not, order an A.

When you purchase an OrcaFilter purchase an A/C filter. We supply 3 Universal Gaskets that fit most A/C compatible pumps.
