Tri-X Replacement Filter Cartridge

Tri-X Replacement Filter Cartridge

This ceramic fiber cartridge filter was introduced in the 2004 Hot Spring high performance spa models. In 2006 the Tri-X became available as a replacement for the common polyester filters (aka paper filters). The unique design enables it to filter twice the water per minute than a common filter. You don’t have to clean it as often either! This filter can replace the 71825 filter in all 1990-current Hot Spring Highlife spa models, 1998-2002 Hot Spot models and all Solana X, RX, SX & TX spa models.

Disposal Instructions

When the filters have reached their usable life, you can discard the Tri-X filters in the household trash.

Frequently Asked Questions

Are the Tri-x filters ceramic or paper?  Tri-x filters are a high performance filter made of a ceramic like material.  They are different than the polyester filters which are commonly referred to as "paper filters".

Are these filters marked on top with P/N 0969601?  Yes, the numbers 0969601 is embossed on the top side of the filters.

My Hot Spring spa came with Tri-x filters, can I replace them with the basic paper filters?  The filtration system and jet pump system in the Hot Spring spas with Tri-x filters are designed specifically for use with the Tri-x filters.  It is not recommended to use the basic paper filters which could cause adverse effects on the jet pump system.  On a temporary basis, 1 of the paper filters could be uséd on the filtration system, the gray standpipe and cap. 

Is the Tri-x 73178 filter the same as the 73250 filter?  Yes, the 73250 part number is uséd by the manufacturer for identifying a case quantity vs 73178 which identifies the individual unit.

Can you clean the Tri-x filters in the dishwasher?  Yes, the Tri-x filters are safe to use in a high pressure water environment.  If using a dishwasher, place the filters in the dishwasher without any cleaner on them and only use the rinse cycle with no detergents. 

Do you have to use filter cleaner on Tri-x filters?  Yes, you should use a product like Freshwater Instant Filter Cleaner or a granular Freshwater Filter Cleaner on a quarterly basis.  Between chemical cleanings we recommend that you rinse the filters monthly.
