Waterdrop AP431 Cartridge, Whole House Scale Inhibitor Inline Water System, Replacement for Aqua-Pure AP431 Hot Water Scale Inhibitor for AP430SS

Please note - This product is NOT a regular pre-filter. By adding proper amount of food-grade polyphosphates into your source water, it can inhibit scale build-up on a certain level. Therefore, it will NOT force all the water flowing through the filter as a normal filter does. Only a part of the source water will flow through the filter body and absorb food-grade polyphosphates, which is a normal phenomenon.

Protect Your Appliances - This scale inhibitor system helps keep your water heaters, hot water using appliances, and plumbing fixtures protected from scale buildup while also maintaining efficiency and saving energy.

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.

Premium Material - Scale Inhibitor Water Filter System is equipped with a firm and rust-less 304 stainless steel connector, which is durable and less prone to be damaged. Whole house scale filter employs food-grade, BPA-free plastic, providing with safe water.
