  • Color display for color changing NSF certified resin/lifespan: We use a transparent shell and place NSF certified purple color changing resin filter cartridges. When the resin in the filter cartridge loses its effectiveness, it will turn brown, reminding us that the pure water effect will decrease, making it easier for us to observe the lifespan of the resin more intuitively. This allows us to replace the filter cartridge in a timely manner and eliminates the need for blind testing of lifespan
  • Effectively Removes TDS in Water:Our water spot remover filter uses pre-mixed premium resin, reduces mineral and calcium-magnesium ion particles in the water, can reduce scratches and wear on the paint during washing.When water passes through the resin, TDS (total dissolved solids) are removed. Each cartridge will remove approximately 1,800-2,000 TDS before you need to replace the resin.
