Couldn’t be happier with my decision to install our water softener and reverse osmosis filter. The difference it has made in our water quality is incredible improving so many aspects of our life. Having pure clean water on top is such a luxury and we feel good knowing we are not reliant on moldy brita pitchers or endless water bottles. Our dishes and ice are better and we even noticed a difference in our skin and hair. Also 5 stars to Sean the service rep who helped me track down a sediment filter when they were in short supply. He personally made sure one was sent to me straight from the warehouse and he couldn’t have been more professional and courteous.. David. Wed Apr 22 2026

Replaced my Culligan system with this and am very happy with the change. Had my plumber install it with new Kohler faucets in a kitchen remodeling project and it works great. I added a separate bar faucet that matched my sink faucet - which is also on a different Kohler filtration system. Filters are easy to order and replace every 6 months. Overall, very pleased and way cheaper than other solutions.. Anonymous. Fridley, MN. Wed Oct 22 2025
