With such a huge range of cartridge filters available online, finding a replacement for your particular application can be a bit daunting. Here we explain how to correctly measure your existing cartridge filter, which helps to narrow down your search.

Tip: The best way to ensure you are purchasing the right filter cartridge for your application is to match up the new cartridges dimensions with your existing cartridge you are looking at replacing.
These dimensions are listed in the description of each and every one of our filters.

Diameter A (length): Measure directly from one side to the other.

Length B (width): Measure through the inside hole from one side to the other, this will ensure any small lips around the hole are included in the measurement, which may change the length.

Hole C (hole width): Measure the filter hole from one side to the other.
