Introducing Version 3 | Arctic Spa Pro Filter Adapter

New Key Features

  • Use Your Existing Skimmer Covers – Your existing Arcitc Spa Pro filter skimmer covers are now compatible with this V3 Kit. Simply slip them over the T-380 filters. (on the V2, the Type A filters were slighty too wide for this to work)
  • Increased Filtration – Two T-380 filters are utilized per filter slot compared to just one Type A filter utilized on the V2. This unlocks more filtration cleaning power per adapter.
  • Improved Base Support – Completely new base adapter design with better support.

This adapter will save you 88% off in future filter costs.

  1. fantastic product! fit well. as soon as my OEM filters started needing replacement after 2 1/2 months, I thought holy cow this is going to be an expensive spa to maintain, considering everything else in the spa works fantastic. This filter situation was going to be a real problem and I saw this online and thought wow that’s the solution! bought it, installed it, water was clear the next morning. fits Fantastic, filters are washable. Great product. thank you

  2. The water has been much clearer!
