Review on High-Efficiency Aquasana Whole House Water Filter System - Advanced Carbon & KDF Home Water Filtration - Filters Sediment & Removes Up To 97% Of Chlorine - 600,000 Gallons - EQ-600 by Darin Grosz

Many reviews talk about the installation and how the user feels the unit performs but do not provide actual testing data to show the difference/verify it actually works.Since the mfg doesn't provide test results either(that I could find), I was concerned/sceptical regarding the softening and smell reducing ability when buying this product as I have very hard and alkiline well water with a strong Hydrogen sulfide smell.To get some form of data I purchased First Alert home one water test and conducted the test several months prior to installation and again a few days after. The results show a significant change from hard to softer water along with a noticible decrease and near elimination of the hydrogen sulfide smell.Although the performance is great, I don't recommend installing this if you don't have basic plumbing and carpentry skills. If you do have these skills, it isnt terribly difficult to install but you will spend several hours to complete. It would have also been helpful having written instructions(aside from flushing) along with shims to line up the pre and post filter with the main filters.Lastly, the pro kit will only work with PEX and would have been much easier to use if they provided the slip on shark bites vs the crimp. This would save the installer money on the tools and additional parts needed for crimp fittings.Overall I am very pleased but probably would have purchased much sooner if they had more data on performance and details on installation.Note: other constituents tested with the first alert kits were already at low/acceptable levels and showed no change.
