Hot Tub & Swim Spa Replacement Filters

Shop replacement filters for Arctic Spas hot tubs and swim spas. We carry Silver Sentinel and Atlantis disposable filters, pleated cartridges, carbon pre-filters, and combo packs in both thread-in and drop-in styles to fit current and legacy Arctic Spas models.

How to find the right replacement filter for your hot tub

Atlantis and Silver Sentinel filters use antimicrobial technology to reduce bacteria buildup between water changes. Pleated filters offer reusable filtration that can be cleaned and reused multiple times before replacement. Not sure which filter your spa needs? Thread-in filters twist into the filter housing, while drop-in filters sit inside a filter basket — check your owner's manual or contact us for help matching the right filter to your model. You can also bring your old filter into our Kitchener, London or Windsor showroom and we'll match it for you.

How often to replace a hot tub filter

We recommend replacing disposable filters every 3-4 months and deep-cleaning pleated filters monthly for best water quality. All filters ship from Ontario with free shipping on orders over $169.
