Silver Sentinel Disposable Filter (Thread-In)

Our most popular filter — change it quarterly, clean it never.

The Silver Sentinel disposable filter threads into the ArcticSpas-logo intake on every Arctic Spas hot tub built 2009 or later, plus the current Core and Classic Series. Run it for about three months, then drop it in the recycling bin and thread in a fresh one. No hosing pleats, no overnight soaks, no filter cleaner to buy.

Hundreds of layers of porous polypropylene trap particles all the way through the filter body, filtering down to 1 micron — typical pleated cartridges stop around 70 microns. Today this filter is manufactured under the Atlantis name — same filter, same fit, newer label.

Fits: Arctic Spas 2009–2019 + current Core and Classic Series · Includes: 1 filter (about 3 months) · Also available as a 3-pack or 5-pack.
