Pure, Clean Water. Only Mother Nature does a better job

Our multiple pump system provides continuously circulated water for constant filtration, even when the spa is not in use. So the water is always hot, always clean.

Water - it's the essential ingredient in a spa. So you'll find that the water in a HotSpring spa is always crystal clear, fresh and pristine. To ensure it, we've created a comprehensive, 3-part filtration system.

Continuous Filtration

In a HotSpring spa, all the water is continuously being filtered. In fact, the spa's entire contents are completely filtered 10 to 15 times each day! It works like this: the SilentFlo^® 5000 pump - a dedicated, energy efficient, low-amp and, of course, quiet, pump-constantly draws water from the spa, runs it through the filter and the heater (heating only when necessary), then back to the spa. So energy efficient, it costs less to operate than a 75 watt light bulb.

Because the SilentFlo 5000 pump is totally automatic, there's no need to program long cleaning and heating cycles like you do with other spas. Nor do you have the wear and tear, energy drain or noise of a large jet pump running during those cycles. Quietly, your HotSpring spa is always hot, clean and ready to enjoy.

100% No-Bypass Filtration

100% No-Bypass Filtration means that all the water passes through the filter before it re-enters the spa. With other spas, water can bypass the filter when the jets are on - the very time when you're in the spa and need clean water the most. Bypassing occurs when there's too much pump and not enough filter-forcing unfiltered water, complete with body oils and debris, directly back into the spa. Only HotSpring spas filter all the water all the time.

Balanced Filtration

To ensure our filter cartridges are not overburdened so there's no need to bypass them, their square footage is matched with the gallon-per-minute flow of our pumps. Completing the system, a floating skimmer directs surface debris into the filter compartment and prevents it from floating back into the spa. The filters are top loading for easy access; simply lift the filter lid to remove the cartridges for cleaning or replacement. Just like rotating the tires on your car, frequent rotation of the cartridges ensures their extra long life. And thanks to our multiple filter design system, there's no need for sidewall suction fittings-providing an extra measure of safety.

Our High Performance (HP) models pump an extremely large quantity of water. To ensure no water bypasses the filters, we've developed the new-to-market Tri-X T 3-dimensional filter. Because it filters by depth rather than just surface filtration, it filters ten times more gallons per square foot than other filters. And they're dishwasher-safe, so they're even easier to maintain!

Hate to bail? we do too. And with a HotSpring spa, you won't have to. Unlike other spas which have side wall drains, HotSpring spas are designed for easy and simple draining. A convenient floor drain eliminates the need to bail water.
