I was impressed right from the start. Upon opening the box I saw the best, neatest, orderly packing job that I have ever seen on anything that I have ordered by mail. Every thing was well placed and packed tightly. Excess space (which was very little) was filled in with air filled plastic packing, not Styrofoam peanuts (I hate those things). Everything was completely in tact and ready to install. The installation was very simple, mostly because I already had an existing filtration system.
Before I removed the old system I used the TDS water tester that came with the unit to test the water from the faucet and the water from the old system. To my surprise they both read 148 on the TDS! No difference between the filtered and unfiltered water. I followed the instructions for installing the new unit (very plain and straight forward) after removing the under-the-counter filters from the old system. I used the existing fill tube, inlet water valve, outlet tube, and dispenser assembly, making the installation much quicker. After finishing and checking for leaks (there were none) I tested the the the RO-90 with for TDS again. It read a TDS of 4, a very big difference. I also found that the water tastes enormously better. The improvement is quite noticeable to the taste. Needless to say: I am very, very satisfied. Everything concerning this reverse osmosis system shows of a company that takes pride in their product, pride in their packing facility, and truly cares for their customers well being.

When understanding a drinking water filter’s contaminant reduction capabilities, there are two important criteria to consider: NSF Certification and chlorine & chloramine reduction capability. First, make sure the filter you are considering is NSF Certified to Standards 42, 53 and 401. Reverse osmosis systems should also be certified to NSF standard 58. The National Sanitation Foundation (NSF) is the most credible third-party testing organization and “NSF Certification” is considered the Gold Standard for third-party certification in the industry.
