Atlantis Filter Thread-In | Silver Sentinel Replacement

The Atlantis Filter is the new and improved version of the Silver Sentinel — the maintenance-free disposable filter for Arctic Spas. It fits all Arctic Spas from 2009 through 2019 and the current Core and Classic Series models, threading into the ArcticSpas-logo intake.

Atlantis filters capture particles inside the filter body, not just on the surface, using thick layered filter media that filters down to 1 micron — where typical cartridge filters stop around 70 microns. Completely maintenance free: install it, forget about it, and replace it every three months. No cleaning, no soaking, fully recyclable.

Fits: Arctic Spas 2009–2019 + current Core and Classic Series · Includes: 1 filter (about 3 months) · SKU: PRT-900007

Prefer to stock up? The 3-pack covers most of a year. Not sure which intake you have? Bring your old filter to any of our three Ontario showrooms.
