For years, the hot tub industry has made great strides, but filter technology has lagged behind—until now. Hot tub owners know the struggle of maintaining traditional filters, which are difficult to clean, prone to clogging, and, worst of all, need frequent replacement. Traditional filters only last a short amount of time before needing replacement, often no more than a year or two, which results in countless filters being discarded into landfills, contributing to unnecessary waste.

The Infinity Filter changes all that. Its innovative design not only extends the life of your filter, but it also cuts down on the hassle of upkeep. With better circulation and easy maintenance, this filter will keep your hot tub running at peak performance while ensuring the water stays clean, clear, and inviting. Replaceable media pouches ensure long term performance.

Switch to The Infinity Filter today and enjoy worry-free relaxation for years to come!

Choose your thread type

1.5" fine threads (1.5" MIP thread base model) for:

• Coleman Spas
• Costco Spas
• Hot Spring Spas (simply unscrew the suction tube, then the threads are exposed). 1-5 filters. ACE® salt cartridges can be placed outside the filter. If the filter tube does not unscrew you will need a different model that we are currently working on. If you have a 1 or 2 filter Hot Spring model, this will most likely affect you. Check to see if the standpipe unscrews before ordering the 1.5" fine thread. Contact us for availability. Not for Limelight or Flair models.
• Hot Spring Limelight & Flair Spas (the standpipe is glued into place, which requires the Limelight and Flair version – currently unavailable).
• Hydro Spas
• Vita Spas

If you don’t have a male or female thread on the bottom of your filter, these will only work if the filter standpipe is removable.
