Simple Installation w/ Great Results

SetupFirst off, I live in an area with very poor water quality. The water is poor in terms of hardness and overall TDS. These are the two primary attributes that affect taste and can easily be measured. A simple TDS meter can be had for less than $15 on Amazon. Hardness/scaling is generally noticed by water spots on your dishes, and white or green crust that builds up on your faucets. Water from my tap tested at over 500 TDS which is extremely bad.InstallationAs far as the installation, it really is quite simple. When they say an average person can install this in 30 minutes, they are being accurate. I took my time reading through all the instructions and watching the video installation and probably finished in no longer than 45 minutes. A simple drill should be all you need. Drilling a quick hole in the drain pipe & installing a slot for the included water faucet, if you don't already have one, are the only things that may give you pause. These are covered in the manufacturer's YouTube video and I felt more than comfortable after watching it. Many people likely wouldn't need to drill a slot for the faucet, but I did. They give you a sizing circle but I actually went much smaller as the actual faucet is smaller than indicated by the sizing circle.ResultsAs originally mentioned, my water tested at over 500 TDS. Using the highest quality Samsung fridge filter from WaterDrop my TDS dropped by about 100 and was in the low 400's, which is still quite high. After completing draining I tested my water at approximately 100, which was higher than expected. As I ran the water a bit longer I saw it drop further. After running through some cycles the faucet started producing water that tested as low as 40 in terms of TDS. This is extremely good in terms of where I started. The system claims to reduce TDS by about 90% or more and that's right where I am at. If you have a better starting point, your results should be even better.Other ThoughtsOverall I'm thrilled with this little device. My in-laws have a traditional R/O system that takes up the entire cupboard under their sink. Doing some research, these can have issues with mold growth if left unused for any sort of prolonged period. I feel much better with this system and it fits in nicely aside my waste disposal unit. This system has a water waste ratio of 1:1 meaning that for every one cup of filtered water you produce, you produce one cup of water waste that goes down the drain. This is actually substantially better than most systems I've seen but worth noting if you care about that. It produces a sort of low hum when in use but I actually kind of like it. It lets me know it's working. I drink tea almost every day and now I finally have good water that won't cause build up on my electric kettle. The taste is akin to bottled water as well.Additional ConsiderationsOne of the things that bugs me is that my fridge produces ice that ends up flaking in water. As it melts you can tell there are clear particulates in your water. These are termed as "harmless" and should just be minerals that are in your pipes but I definitely don't like it. Going forward I may pick up a second unit to hook up behind my fridge. The only challenge would be figuring out how to connect direct to the unit since it would not be directed to the included faucet. Overall I think this is one of the best purchases I've made in the past year and have been happily using the system for over a month now.
It works

Easy use, clear taste for great coffee.
Super easy install

I honestly have no experience in installing anything and I figured it out. I
Clean, Fresh, Reverse Osmosis Filtered Water from the kitchen sink

Bought the product b/c my brother-in-law installed same one in his house 9 months ago and they have great tasting, clean water without the use of a bulking, stand alone water machine like we had.<br>Installation is pretty straight forward, but you do need an electrical outlet under the sink, something we had to install. We were spending almost $1100 per year on bottled water service, so even with the added cost of the electrical outlet the system will pay for itself within the first year.
No more bottled water!

We have been looking for years for a filter that would fit in our cabinet. Finally! No more bottled water. The unit was very easy for my husband to install.
