Polar Pro Filter Insert | Hybrid | Pleated Depth

The Polar Pro Hybrid Pleated Depth Insert is the replaceable filter cartridge that drops into the Polar Pro Filter Assembly on every Arctic Spas Custom Series hot tub built from 2020 to present. This is the most popular Polar Pro filter media — and the same insert that comes pre-installed on new Arctic Spas Custom Series tubs.

What it does

The Hybrid insert combines a traditional pleated outer layer with an inner depth-filtration core. The pleats catch large debris like leaves, hair, and body oils; the depth layer captures finer particles and holds them inside the filter body. The result is noticeably clearer water than you'd get from a pleated-only filter.

The Polar Pro system: housing + insert

The Polar Pro filter is built as two parts: a reusable plastic housing and a replaceable insert. This insert is designed to fit inside the Polar Pro Filter Assembly. If this is your first Polar Pro filter purchase, you'll need both. After that, you only ever replace the insert — saving money and keeping a perfectly good plastic housing out of the landfill.

Other insert options

• Traditional Pleated Insert — the classic pleated cartridge, the simplest option.
• Combo Hybrid + SilverCore Insert — the same Hybrid pleated-depth filtration plus SilverCore antimicrobial technology. Recommended for mineral purifiers and saltwater systems.
