How a Hydrefiner Water Filtration System Works

Experience clean, refreshing water with every glass. Here’s how the Hydrefiner system by RainSoft Great Lakes Water Treatment transforms your tap water into high-quality water for drinking and cooking:
Step 1
Cold water enters the system from your home’s water supply.
Step 2
Water is pushed through an activated carbon block pre-filter, which reduces chlorine taste and odor, as well as various organic contaminants.
Step 3
The partially filtered water exits the carbon block pre-filter.
Step 4
Water then flows through a second-stage filter, which captures microscopic particles and sediment as small as 5 microns.
Step 5
The result is highly polished, ingredient-quality water delivered fresh through your dedicated RainSoft Great Lakes Water Treatment faucet—perfect for drinking, cooking, and everything in between.
+Ask your local RainSoft dealer for a Performance Data Sheet for additional information regarding specific contaminant reduction claims.

We recently had a system installed, and had a great experience working with Great Lakes Water Treatment. The 3 biggest positives: 1) Health: the taste and convenience of the filtered water system has translated into us drinking much more water than we were before 2) Hair: the softened water is much nicer for hair texture and 3) Great install experience: Dom did a great job getting the system set up in a nice, compact way. Thank you!
Absolutely fantastic service and product! Every step of the way, the install and information was first rate. My tap water no longer smells like a swimming pool, and I can drink the Reverse Osmosis without a care. Also, the detergent free washing machine unit is a marvel! I was skeptical, but it's better than advertised. Thanks so much!
