ThermoFiltration keeps your water crystal clear!
Filters the water ten times more than competitive brands!
Measuring filtration
The #1 factor in determining the quality of a filter system is the number of times in one day 100% of all water passes through the filter. This number shows how quickly your water will reach clarity after it has been used. In-ground swimming pools filter 100% of their water twice a day and standard swim spas filter only 4 to 5 times a day. ThermoSpas filter 100% of the water in our swim spas 35 times per day.
