### ⭐⭐⭐⭐⭐ Review
*by K***Y on 8 July 2024*

I had been looking for a system that would be easier to service than the ones I had purchased before. It had to work on well water and wouldn't break the bank. I took a chance on this "Tankless" system and was more than surprised at how easy it was to install and ultimately how well it works. It took less time to install than to remove the old system! Once in, I was actually able to see how it was working via the PPM gauge on the front of the unit. It also tells you when you need to replace an individual filter, (there are three). No more using a stick-meter to test the water. Our pre-filter at the well pump doesn't do that! This system works great on well water. If you have city water, you're going to LOVE how it works on yours! My wife and I live up in the mountains of Colorado on a well. Over the years we have used all kinds of water filtering systems to augment the well pump filter for cooking, drinking and most important, COFFEE. All had the space-eating holding tanks under the counter and all worked adequately. All were similar in that they required messy removal of the old filters from their water-filled, hard to unscrew tubes and periodic sterilization of the osmosis chamber. Servicing the old systems was always a long, involved chore. The new unit comes with easy to follow instructions. The water tube feeds are all color-coded, larger diameter "cut and plug-in" types. Much easier to handle than the old small diameter screw-on attachments that required rummaging through the old toolbox for the right wrench. A few cuts on the new water tubes to fit length needed, push them into the color coded plug-ins, attach the excess water line to the house drain, plug the electric into the wall socket under the sink and DONE! Note: The system comes with a really nice counter-mount faucet in chrome. However, I used our already installed brushed bronze one at the Bosses' direction. (You married guys will know what I mean.) It took me about fifteen minutes to install the new unit. Heck, it took me THIRTY just to remove the old system and take it down to the trash! Now we get clean, great tasting water on demand, no sulfur smell, no leaks, no muss no fuss. The replacement filters snap in and out and have their own sensors to inform me when that is needed. AND those replacement filters are cheaper than any of the old ones we used on the former systems, I checked. To be clear, I NEVER write reviews of things, but this is a break-thru product that WORKS and (IMHO) is several cuts above anything I've bought previously. It saved me time and money. I have neither to spare. I was compelled to share my experience with others about it just in case you're like me and would rather spend the extra time it would have taken to re-install and service an old style system.... FISHING. Mack in the mountains.
