High Flow Rate – The 3/4″ NPT inlet/outlet connections of our water scale inhibitor ensure a powerful flow rate of up to 10 GPM. Stable flow is also ensured with large water flow.

Extended Lifespan – Enjoy clean water by your Scale Inhibitor Water Filter System. Each cartridge can last 6 months with regular use, which will vary based on water conditions. Throughout this time frame, you will get maximum performance.Pleasse install our system in upright position so as to ensure effective water scale reduction and prolong lifespan.
