Description
Overview
This filter suits the smaller Freeflow spa models where space is tight and fit really matters. If you are running a TLX or RLX25 Mini, this cartridge matches the original size and thread so it screws in cleanly without forcing it. Using the correct filter keeps the circulation steady and avoids the slow drop in flow that usually shows up when a cartridge is past its best.

Where to Use It
This filter is used in compact spa systems where the housing takes a shorter cartridge with a fine thread connection. It is common in Freeflow Mini spas and similar skim filter setups. These systems rely on the filter fitting properly, as even small size differences can affect circulation.
How to Use
Turn the spa off and give the system a moment to settle before removing the old filter. Unscrew it using the top handle and check the housing for grit or buildup. Screw the new filter in by hand until it sits firm. There is no need to overtighten it. Once fitted, restart the spa and make sure the water is moving normally.

Pro Tip
If your old filter feels loose or wobbly once installed, check the thread carefully. Fine threads need to line up cleanly. Forcing them can damage the housing and lead to leaks.
FAQs
Is this the correct filter for Freeflow TLX and RLX25 Mini spas?
Yes. This cartridge is sized to suit those models when the measurements match.
My original filter has a flat top, not a handle. Will this still fit?
Yes. Some originals were flat topped. The handle does not affect compatibility.
How often should I clean this filter?
Most spa owners rinse it every two to four weeks, depending on use.
When should the filter be replaced?
Usually every six to twelve months. If rinsing no longer restores flow, it is time to replace it.
Can this be used in other spa brands?
It may suit other spas with the same dimensions and thread, but always check measurements first.
