The operational cost of the Purezone will depend on how many months you operate your spa and what measurement frequency you select. 

If you operate your spa seasonally, i.e. Fall and Winter months only, the cost will be less.  The operational cost will also vary depending on which measurement frequency you select in the app.  To calculate the operational cost simply multiply the cost of the Purezone P3 cassette 3-pack by the number of months you operate your spa.  You will need to take into account your choice on how frequently you want to measure your spa water.  See below for more information.

Purezone P3 cassettes

• Each Purezone P3 cassette should last about 2 months based on every other day measurements

  • Each Purezone P3 cassette has 48 water measurement testing pads 

  • If you select to measure "Every day" in the Purezone app, the cassette will last 48 days - Approximately 1.5 months

  • If you select to measure "Every other day" in the Purezone app, the cassette will last 2 months, with capacity for additional on-demand measurements! 

  • Note:  If you perform additional on-demand water measurement tests, this will of course reduce the life of the cassette
