How to Measure a Pool Filter Cartridge

Can't find the exact measurement for your filter? Don't worry, we'll help you figure out which replacement filter cartridge is the right one for your system

Our <a href="https://mrpoolman.com/collections/pool-filter-cartridges">Pool Filter Cartridge Collection</a> has an automatic measurement finder that will recommend the correct replacement pool filter cartridge based on the Length, Width, and Hole size of your current filter.&#xA0;Please do note that these measurements may be off by a tiny fraction of an inch, but it would not affect the performance of your filter. So if your find yourself 1/32 of an inch &quot;off&quot; from what we&apos;ve listed on the filter finder, simply select the value closest to your measurement.&#xA0;For measurements that are off by more the 1/5 of an inch, please send the photos of your filter cartridge and the measurements through our Contact Us page below so we can recommend a replacement pool cartridge for you or help you source one if it&apos;s not available on Mr Pool Man.
