Polar Pro Filter Insert | Combo | Hybrid Filter with SilverCore

The Polar Pro Combo Hybrid + SilverCore Insert is the premium replaceable filter cartridge for the Polar Pro Filter Assembly used in every Arctic Spas Custom Series hot tub (2020–present). It combines Hybrid pleated + depth filtration with SilverCore antimicrobial technology — actively killing bacteria and microorganisms as your spa water passes through the filter. What it does The Combo insert does three things at once: a pleated outer layer captures large debris like hair and oils, a depth-filtration core traps fine particles, and SilverCore silver-ion technology kills bacteria and microorganisms that get caught in the media. The filter doesn't just collect the contaminants — it neutralizes them. Best match for mineral and saltwater systems The Combo Hybrid + SilverCore insert is fully compatible with Arctic Spas mineral purifiers and saltwater sanitization systems. If you're running a low-chlorine or low-bromine approach to keeping your spa clean, this is the insert we recommend. The Polar Pro system: housing + insert Polar Pro is built as two parts: a one-time reusable housing plus a replaceable insert. This insert is designed to drop into the Polar Pro Filter Assembly. New customers need both; after that, you only replace the insert — better for your wallet and for the landfill. Other insert options Traditional Pleated Insert — the classic pleated cartridge. Hybrid Pleated Depth Insert — pleated + depth filtration, the most popular option and what ships with new Custom Series spas.
