Continuous, Silent Filtration

In a HotSpring spa, the SilentFlo 5000 circulation pump works continuously, filtering the spa’s water 24 hours a day. It’s totally automatic, so there’s no need to program long cleaning and heating cycles as in other spas. Nor do you have the wear and tear, energy drain or noise of a large jet pump running during those cycles. Operating silently and efficiently, your HotSpring spa is always hot, clean and ready to enjoy.
100% No Bypass Filtration

With 100% No-Bypass filtration, all the water passes through the filter before it re-enters the spa. With other spas, bypassing occurs when the jets are on, forcing unfiltered water directly back into the spa. With a HotSpring spa, the gallon-per-minute flow of our pumps is carefully matched with each spa’s square footage to achieve balanced filtration, so there’s no need for bypassing.
TRI-X Filter Technology

The patented Tri-X filter has twice the cleaning area of a similarly-sized cartridge, filtering the water three-dimensionally through both the surface and depth. Dishwasher-safe, it’s easy to maintain. Included as standard on many models, Tri-X filters can be used on any HotSpring spa. Available only on the Vista, Grandee, Envoy, and Aria.
Ozone System

Hot Spring spas come standard with the FreshWater III high-output ozone system. Working 24/7, it continuously injects millions of tiny, highly-concentrated ozone bubbles into the water, thereby neutralising contaminants on contact. The system uses a corona discharge cell, requiring virtually no maintenance.
Enjoy peace of mind knowing the optional ACE Salt Water System is creating the sanitisers you need to keep spa water sparking — even if you haven’t given water care a thought. Only HotSpring® offers this automated, low-maintenance saltwater system that enhances the quality of your spa water.
