ThermoClear Purifier Cartridge
Price $34.99


ThermoClear is an EPA-Approved mineral sanitizing cartridge system. ThermoClear has become the preferred choice of most ThermoSpas customers because it is simple to use, reduces maintenance time (especially during non-use), and virtually eliminates the harsh odors of chlorine and bromine. ThermoClear cartridges require no maintenance, simply replace every 4 months.

Maintenance Program: Insert a new ThermoClear cartridge into your filter cavity. Then simply add 2 ounces (for 1 to 2 people and an additional ½ ounce for each additional user) of Spa Activator each time after you use the spa and 2 ounces each week when spa is not in use. Always remember to replace a new ThermoClear cartridge every 4 months. If your spa is experiencing heavy use, or if you are simply seeking added sanitizing protection you can add 1 ounce of Chlorine each week.
