How do I find the right size of my whirlpool filter?

Here we show you how to properly measure your existing whirlpool filter and then order the appropriate filter from us.

1. filter length:

Measure only the length of the filter without the thread or handle at the top or bottom end.

2. Filter diameter

Measure exactly in the center of width the diameter. The easiest way to do this is with a caliper (vernier caliper).

Once you have these two measurements, go to this link to find the appropriate filter for your spa.
