RUNXIN provides a series of products used to soften and filter water, making it safe to drink. The water filter, using food-grade activated carbon, removes unpleasant odors, residual chlorine, heavy metals in the unpurified water, as well as improves the taste of the water. The water softener can reduce calcium and magnesium contents using a food-grade resin, decreasing water hardness.

Residential water resources with a high degree of calcium and magnesium along with other contaminants can create lime scale in taps, sinks, toilet bowls, and bathtubs. But it can also damage people’s health over time if used for drinking.
