New Arctic Spas Polar Pro Filters for Custom Series Spas

New Arctic Spas Polar Pro Filters: A Smarter Replacement for Progressive Filters

Arctic Spas has introduced the Polar Pro filtration system, the next generation of filtration options for compatible Custom Series hot tubs and All-Weather Pools.

As explained in the Arctic Spas Polar Pro filter overview video, the Polar Pro line replaces the familiar Progressive filter design with a reusable outer canister and a choice of three replacement filter inserts. This gives Arctic Spa owners more flexibility when choosing how their spa water is filtered.

โ„๏ธ What Is Different About the Polar Pro Filter System?

The biggest change is the new reusable filter canister and replaceable insert design.

When converting from an older Progressive filter, you will generally begin with a complete Polar Pro assembly. The full assembly includes:

  • A reusable outer canister
  • A Polar Pro filter insert

Once the reusable canister is installed, future filter changes will only require replacing the internal Polar Pro insert instead of purchasing another complete assembly. The linked Polar Pro assemblies list PRT-900170, PRT-900180, and PRT-900190 as available replacement insert options.

๐Ÿ†• Polar Pro Full Filter Assemblies

A full assembly is the best starting point when converting from an older Progressive filter or replacing the complete filter housing and cartridge.

๐Ÿ”น PRT-900150 Polar Pro Pleated Filter Assembly

The PRT-900150 Polar Pro Pleated Filter Assembly includes the reusable canister and a traditional pleated filter insert.

Its pleated media provides a large filtration surface for capturing dirt, oils, debris, and suspended contaminants. The insert can be removed, rinsed, and reused as part of regular spa maintenance.

๐Ÿ”น PRT-900140 Polar Pro Pleated-Depth Combo Assembly

The PRT-900140 Polar Pro Pleated-Depth Combo Assembly includes the reusable canister and a combination-style filter insert.

๐Ÿงผ Polar Pro Filter Maintenance Tips

Consistent filter care helps maintain water clarity, circulation, heating performance, and proper flow through the spa.

  • Put the spa into standby mode or turn off power before removing the filter.
  • Inspect the cartridge regularly for oils, debris, discoloration, or restricted flow.
  • Rinse reusable pleated inserts approximately every two to four weeks, adjusting for spa use and bather load.
  • Use an approved spa filter cleaner when deeper cleaning is necessary.
  • Avoid damaging the pleats with excessive water pressure.
  • Replace inserts that remain dirty, damaged, collapsed, or restricted after cleaning.
  • Maintain proper sanitizer, pH, alkalinity, and calcium levels.
  • Never rely on filtration alone to sanitize spa water.

Premier Pool & Spa also offers free professional water testing to help identify water balance issues that may be shortening filter life or causing cloudy water.
