How to clean Tri-X Filters in a dishwasher
Tri-X Filters are gaining in popularity due to their unique ceramic design which allows it to filter twice as efficiently as a standard paper filter. They have a life expectancy of up to 5 years with proper maintenance. They are able to be used as a direct replacement for most paper/fabric filter cartridges on Hot Spring Highlife models from 1997 to current, even if it originally came with a different filter. This filter comes standard on current Hot Spring Models: Grandee, Vista, Envoy and Aria.
This filter has amazing abilities. However it’s ceramic design makes people wonder how to clean it and how often to clean it. The good news is that cleaning Tri-X filters is no different than cleaning any other filter with the exception that half the work can be done by a dishwasher (unless your spa is using Baqua Spa water care products).

How often do I clean a Tri-X?
Before we go into how to clean the filters we should discuss how often the filters should be cleaned. Tri-X filters should be cleaned regularly to maintain water clarity. How regularly will depend on the frequency and duration of the hot tub’s use and the number of people who get in the spa. Getting in with lotions or cosmetics will increase how often the filters will need to be cleaned. How much dust, dirt, leafs etc that get in when the cover is open will also have an impact. All of these things determine the appropriate time between filter cleanings. With that being said, with normal use, a filter should be rinsed every two weeks and cleaned with filter cleaner once a month.
How to Remove a Tri-X Filter for Cleaning
- Turn off power to the hot tub (unless you have a second set of clean filter to put in immediately to prevent damage to the pumps and heater)
- Remove the filter lid
- Unscrew the filter cap (located on the top of the filter).
- Caution: Do not remove the filter standpipe while removing the cap. If the standpipe is accidentally unscrewed while removing the filter cap, immediately separate the two components and screw the standpipe back into the spa. Standpipes should never be removed while water is in the spas as objects could get into the plumbing.
- Remove the filters
- To reinstall the filters, reverse steps 1 to 3. The Tri-X can be placed onto the standpipes with either side facing up. There is no wrong way.
- Note: Do not over-tighten filter cap as this could cause the standpipe to become unscrewed during the next filter removal.

The Two Steps to Cleaning a Tri-X
There are two parts to keeping your filter clean. First is removing things from the surface of the filter periodically. Typically, a filter should be sprayed off with a garden hose to remove the leafs and dirt on it one or two times a month with additional rinsing as needed. The alternative to using a garden hose for a Tri-X filter is to put it in a dishwasher. If it is not yet time to use a chemical filter cleaner, the filter can go back into the spa after being sprayed off or washed in the dishwasher.
The second part of cleaning the filter is removing the oils from the filter that come from skin, lotions, or cosmetics that clog up the filter’s pores and prevent it from keeping your water clean and clear. This also removes mineral buildup from the water when combined with using a metal and scale product, preventing a white calcium line from forming on your tub. The metal and scale product will bind with calcium and make it big enough for the filter to catch. A chemical cleaner then removes this calcium from the filter. A chemical cleaning should be done at least once a month with either a spray on or submersion filter cleaner. The chemical cleaning should always be done after cleaning the filter by spraying with a garden hose or washing it in the dish washer.
The two steps of the cleaning process are discussed in greater detail below.
Step 1: Rinsing off the filter:
Method 1: How to clean Tri-x filters using a Dishwasher
Once a month, place the Tri-X Filter into the dishwasher to remove surface debris. To do this, first remove the filters from the spa. Then place the filters in the dishwasher with no soap and ensure the drying cycle is turned off. Some dishwashers do not have the option to turn off the heating cycle so you will need to check to see if yours has the option.
|Dishwasher detergents and rinse agents, such as Jet Dry, can be harmful to the filter if used while cleaning the filter in the dishwasher.|
In the event a dishwasher is unable to remove stubborn debris from the filter or you decide not to use the dishwasher method, you will need to use the garden hose method below. If you only want to use the dishwasher method skip to step 2.
|BAQUASPA NOTE: If the spa water is maintained with Baqua Spa Water Care products, you must use a garden hose and cannot place the filters in the dishwasher. Additionally, for step 2 you must use Baqua Spa Filter Cleaner.|
Method 2: Cleaning the filter with a garden hose
In the event a dishwasher is unable to remove stubborn debris from the filter or you choose not to use the dishwasher, you will need to rinse your filters with a garden hose. The use of either a Filter Flosser, or PowerPic Reach will make this job significantly easier than trying to use a garden hose alone by directing the water into streams that are specifically designed for use with spa filters to remove stuck on debris. To clean using this method, first remove the filters from the spa. Either hold the filter in the air or place on a clean surface then rotate it while using the garden hose to spray the sides to make sure all surface debris is removed. Then briefly spray the inner portion of the filter. Once completed, either place the filter on a clean surface until ready to clean with the filter cleaner or place back into the spa.
Step 2: Removing oils from the filter:
Freshwater Instant Filter Cleaner
To maintain crystal clear water we recommend cleaning the Tri-X filter using a filter cleaner, such as Freshwater Instant Filter Cleaner or Brilliance for Spas Filter Cleaner or Baqua Spa Filter Cleaner to remove minerals and oil buildup every time you drain or refill your spa and once a month in between drain and refills. Be sure to rinse your filter thoroughly before placing the filter back in the spa to prevent suds from forming in the spa water. This step cannot be completed using a dishwasher. Placing a filter in a dishwasher with filter cleaner on it will most likely result in a flooded floor with lots of suds.
|WARNING: Do not use the spa with the filter cartridges or standpipe(s) removed as debris floating in the spa water could accidentally get into the spa’s plumbing, causing damage to the pumps and the heater.|
While not mandatory it is recommended to have a second sets of filters. This allows you to keep one set of clean filters in the spa and take your time cleaning the second. It also allows you to keep your spa turned on while cleaning the second set, not having to worry about having anything sucked into the plumbing.
