Thereye 8 Stage Reverse Osmosis System, 700 GPD Tankless Reverse Osmosis Water Filter, Under Sink RO Water Filtration System, Reduce PFAS/TDS, Smart LED Faucet, 2:1 Pure to Drain, Blue

I've owned and have installed ROS water systems in my home for the past 20 years. Its has always been R/O units with a 4 gallon water supply from Home Depot, Amazon and eBay. After 8 years with my old system, I decided to upgrade to a new ROS unit. I had purchase the iSpring 5-stage ROS system and everything went OK until the faucet began to leak and drip. After 5 days of correspondence with iSpring customer service with no resolution, I decided to return the unit and get a full refund back. After 2 days of reading product reviews, I decided to purchase a tankless ROS for the same price as a tanked ROS. The installation with this Thereye Model ER-WP03 was the easiest ROS system I"ve installed thus far. The unit took less space under my sink, the unit had less tubing to connect and I had the unit working in about an hour. The installation instructions were very easy to follow, tubing marks were well identified, basically a simple step-by-step to follow. The unit was flushed in 8 minutes and the drinking water was 9ppm on my water tester. The unit has a motor pump so, I used one of the packing styrofoam to deaden the motor from under the sink. I will never use a tanked ROS again.

I recently brought my family a water purifier and it is working really good. It took less than 10 minutes to install and it was easy. My water did taste better and the size was nice and small to put into our cabinet. I highly recommend this product if you are looking for clean purified water.

I recently purchased the Under Sink RO Water Filtration System, and I'm very happy with my decision. The installation was straightforward, and the unit fits perfectly under my sink. I'm looking forward to enjoying clean, filtered tap water and am confident this system will do a great job. So far, everything seems to be working well, and I have high hopes for its performance.

Disappointed. Fresh out of the box an RO filter should be giving you close to a 0 TDS this is giving me a TDS of 147. My water without the filter runs at about 187 this makes no sense. Returning

I did a lot of research on under the counter reverse osmosis water filter systems. I finally decided on this one. Even though it only has two filter but it gets the job done. Another thing, the filters are not expensive and last a long time. I love the LED indicator on the faucet. Some complained about the machine being too loud. Those people probably have a very good and sensitive hearing. The motor pumps the water so this is how it can dispenses water out quicker. My favorite part is, the water tastes great! I can’t say anything about the installation because my contractor who renovated my house installed it for me.

Got this for my dad because his tap water is awful and he's terrible with changing his Brita filter. He also is a hoarder so we were looking for something that didn't take up so much space under the sink. My husband said it was an easy install as long as you have an outlet under the sink and can drill a hole on the countertop for the RO faucet.Dad is happy that his water tastes good now, and we can see the huge difference in ppm with the water tester. He says even better than his Brita filter, so it's a win!

I like the fact that it’s slim and the filters are in front so you can easily replace. However, a 120 pound person like cannot twist it to pull the filter out. Looking at it I thought it would be easy to twist but only a man with big hand can twist it and lock it. Why can’t they make it easier? I would need a wrench to do this. The other issue is when I measure the water with my tds stick the number range from 26 to 150. Not consistent. Why is that? Just when I thought it’s perfect. And it’s quiet.

This was easy to install. My wife was complaining about the taste of our city water supply. She loves the quality of this water now. We use it for drinking and cooking water. The flow rate is sufficient for our needs.
