Polar Pro | Filter Assembly

The Polar Pro Filter Assembly is the reusable housing at the heart of the Polar Pro filtration system used in every Arctic Spas Custom Series hot tub built from 2020 to present. Buy the housing once — then simply swap the insert when it's time to replace your filter, instead of throwing out an entire cartridge every six months. Why a reusable housing? Less plastic waste. The housing is engineered to last the lifetime of your spa. Only the filter insert gets replaced. Lower long-term cost. Replacement inserts cost less than a complete filter cartridge, so every change after the first one is cheaper. Designed for the job. Built specifically for the Arctic Spas Custom Series filtration plumbing — drops in with no adapters or modifications. Choose the insert that matches your water The Polar Pro Filter Assembly is sold on its own so you can pair it with whichever Polar Pro insert fits how you treat your spa: Polar Pro Traditional Pleated Insert — the classic pleated cartridge media. A simple, effective filter for spas treated with bromine or chlorine. Polar Pro Hybrid Pleated Depth Insert — pleated media plus a depth-filtration layer that traps finer particles. This is the insert that ships pre-installed on new Arctic Spas Custom Series tubs and the one most owners use.

Frequently asked questions Do I need to buy this every time I replace my filter? No. The Polar Pro Filter Assembly is a one-time purchase. After your first one, you only need to buy replacement inserts. How long does the housing last? With normal use, the housing is designed to last the lifetime of the spa. Which insert should I choose?
