Your hot tub filter works hard to keep your hot tub and spa clean. But after a while, filters can become clogged or damaged leading to dirty hot tub water. While regular cleaning of your hot tub filter can work wonders to extend its lifespan, sooner or later, you’ll need to replace it.
If you’re noticing problems with the cleanliness of your hot tub water or if it’s been a few years since you purchased a new hot tub filter, it might be time to replace it.
Here’s everything you need to know about hot tub filter replacement.
First Try Cleaning Your Hot Tub Filter
Simply remove the filter and spray with a garden hose to remove any debris. Soak the filter overnight in a bucket of diluted filter cleaning solution. For best results, this process should be repeated every three to four months.

How To Find Your Replacement Spa Filter- Method #1 - Find Your Spa Filter Part Number
If you're looking to replace your spa filter, the first thing you need to know is its part number. Finding the part number can be a challenge, but there are a few different ways that you can identify it. The easiest and most straightforward way is to look for the part number directly on the filter itself.
Filters that have their part number stamped on them make replacement a breeze. Simply remove the filter from your hot tub, locate the part number, and use it to order your replacement filter. This method is especially useful if you're unsure of which filter your spa requires, as you can simply match the part number on your current filter to the replacement filter.
If your current filter doesn't have a part number stamped on it, don't worry! There are still other methods you can use to find the correct replacement filter.
How To Find Your Replacement Spa Filter - Method #2 - Using Filter Measurements
In the event that your current filter doesn't have a part number stamped on it, you'll need to use filter measurements to find the correct replacement filter. While this method is a bit more time-consuming, it's still a reliable way to ensure you're getting the correct filter for your spa.
Step 1 - Measuring The Length Of The Spa Filter
To start, measure the length of your current filter. This measurement should be taken from end cap to end cap, with the measurement taken on the outside of the filter. Be sure to write down the measurement, as you'll need it for the next step.
Step 2 - Measuring The Outer Diameter Of A Spa Filter
Next, measure the outer diameter of your current filter. This measurement should also be taken on the outside of the filter, and be sure to measure across the widest part of the filter. Write down this measurement as well, as you'll need it for the final step.
Step 3 - Determine End Cap Configurations
The final step is to determine the end cap configurations of your current filter. This refers to the shape and configuration of both the top and bottom ends of the filter. You'll need to ensure that the replacement filter you choose has the same end cap configurations as your current filter.

Replace Your Filter
Once you have the correct replacement filter, it's time to replace your old filter. While the process may differ slightly between spas, here's a general overview of how to replace your filter:
-
Turn off the power to your spa and remove the old filter.
-
Clean the filter compartment with a hose or other cleaning tool.
-
Insert the new filter into the compartment, ensuring that it fits snugly in place.
-
Turn the power back on and allow the spa to run for a few minutes to ensure that the new filter is working properly.
A dirty or clogged filter can cause a number of issues, from poor water quality to damage to your spa's heating and pumping systems. Keeping track of your filter's part number or measurements is a key part of spa maintenance, and can help you avoid costly repairs and replacements in the future.
