Do not use this system with water that is microbiologically unsafe or of unknown quality unless it has been properly disinfected before or after treatment. Please refer to the Performance Data Sheet for specific information on reduction capabilities and limitations.
Application Limitations
For optimal taste and odor removal, the water to be filtered should be free of oil and suspended solids, and have low levels of iron and turbidity. Please note that actual performance may vary depending on local water conditions.
Maintenance Requirements
The filtering media will eventually become saturated and require replacement. The replacement frequency depends on your incoming water quality and usage. Your local RainSoft Great Lakes Water Treatment dealer can provide guidance on the ideal replacement schedule for your specific situation.
Note: Tank size and local water pressure can impact the system’s operating flow rate.

Your expertise, & your company's service is invaluable!!! Keep up the great work!!! 😊
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!
