**PUREPLUS Countertop Reverse Osmosis Water Filtration System with Instant Hot Water – Adjustable Temperature, High Temp Safety Lock, Large Capacity, 5:1 Low Drain Ratio, BPA-Free – Perfect for Home, Office & Kitchen Use**

I did my homework on this system before my purchase. Based on my findings, the biggest concern was if the ice makers (we have two in our fridge) would function properly. Otherwise, the system functions as advertised.Space saver - absolutelyMinimal waste - VERY IMPORTANT because we live in CA. The old system was sending water to waste 24/7. Not good. This system only sends water to waste while it is dispensing water. Tremendous difference.Water quality and taste - Our water straight out of the tap is between 150 and 350 TDS (total dissolved solids). Water filtered by the PurePlus system is 7-10 TDS. Amazing! The taste is great - Note: Make sure you run the system for AT LEAST 30 min non stop when first installed to flush the filters. If you’re worried about wasting water run it in pitchers or whatever so you can water plants with it.Installation- Every situation is going to be different. The optimal would of course be if you are replacing a conventional RO system. In our case there was only one glitch because a washer was missing from the Feed Water Adapter.Economics - Totally worth it if you are able to install it yourself. Note - it requires you have a power outlet under the sink. Shouldn’t be a problem if you have a dishwasher and disposal. Just make sure you use an adapter where the DW is plugged in so you can also plug in your new PP R/O to the same outlet.Convenience - You will have to make some adjustments. There is a slight delay for the pump to get water through the system. You will also notice higher TDS readings on the faucet display when you turn the faucet because the pump has to push the water through the system. We fill up a gallon pitcher in the morning to minimize waste.Ice Makers - Drum roll…they work fine! Only difference is the cubes are a bit smaller due to the slight delayed response for the pump to move water through the system.Update; The filters are available via Amazon. I ordered a replacement set when I bought the system and they arrived in a couple daysI've had an ROwater system with recirculating tank for 30 years. Wanted to switch to tankless design to save water due to California drought. Have to say, water taste quality doesn't stand up. Have problems with display on water faucet still not resolved. THERE IS NO PHONE CUSTOMER SUPPORT. Just an email address and their response is inconsistent. First email got response in 24 hours. Second request is 48 hours passed and still waiting. I'm ready to send back if they continue to ignore my requests for help. PHOOEY!I was excited to receive my Pureplus filter but now kinda disappointed. It leaves a bad after and doesn’t filter very well. It’s great to look at but as far as drinking naa I don’t think so. I was hoping it would get better after a week but it’s not. I’m thinking about returning it bc 300 dollars is too much to spend especially when my 20 dollar Pur water pitcher was way better. And purified way better. I so much want to love my countertop water filtration system but it’s just not letting me.I purchased it about a month ago and so far I am loving it!!! At first I was a little hesitant because I was worried about the difficulty of installing it, but the description said it was easy to install and I decided to give it a try.The instructions were very detailed and made the installation easier than previous units, with all the connections done in one place. This makes it easier overall. Also, the connection of the individual filters is very simple. Just put it in the designated slot and turn it. I can stick it under the sink and still have plenty of storage space. The unit was perfect. The water tastes refreshing and has no aftertaste. The kids love it. The family loves it too, great.I have never reviewed a product or service on Amazon, but the customer service provided by Pureplus was so exceptional that I feel compelled to share my experience. I cannot say enough good things about the Pureplus customer service.A month ago we were notified by our water company that our drinking water exceeded the maximum level of PFAs (Per- and Polyfluoroalkyl substances) set by the State of New Jersey, and that the water company would not be able to filter out these harmful substances until at least the middle of 2023. I contacted Pureplus to find out whether the Pureplus filter in our refrigerator filtered out PFAs. Pureplus responded immediately, explaining that the filter in the refrigerator did not filter out PFAs, but Pureplus had a reverse osmosis system that did indeed filter out PFAs.Most point-of-use reverse osmosis systems on the market will not fit under our kitchen sink. They are generally designed with a large tank and the space needed for the tank is already used by our food waste disposer. However, the Pureplus system is designed differently. It has a slim design that enables it to fit very easily under the sink.I had a lot of questions that needed to be answered before deciding to purchase the Pureplus system, and I sent several emails to Pureplus to get answers. Pureplus responded to each of my emails very promptly and very thoroughly. I even had an additional question after installing the system, and, again, Pureplus answered right away.Installation of the system was a breeze. So far the system is working as promised and I am very pleased.
