After one week of use, I’d like to share my experience and explain why I chose this particular reverse osmosis system over others. There were two main reasons for my decision: 1. Filter flexibility (ALK to T33 option). This model allows you to replace the Alkaline (ALK) filter with a T33 carbon filter if needed. I wasn’t completely sure whether I would prefer alkaline water long term. With this system, I can simply swap one filter and get 0 ppm water if I choose. That flexibility was very important to me. 2. NSF certification. This system has internationally recognized NSF certification, which can be easily verified on the official NSF website. Unlike some brands that only pay for one-time testing, this certification provides ongoing credibility. For me, that really matters when it comes to water quality and safety. Packaging & Installation: Everything arrived well packaged and protected. The box includes many additional fittings for different installation scenarios — various tubing sizes and even the option to connect the system to a refrigerator. The instructions are clear and detailed. Installation took about 1.5 hours. The most difficult part was drilling a hole in the countertop for the faucet. I had to buy a diamond drill bit for that. My advice: buy a good-quality bit and watch a YouTube tutorial before drilling. I was surprised to learn that: 1. You need to keep the drill bit wet while drilling. 2. You should start drilling at a 45-degree angle. The unit itself is compact and doesn’t take much space under the sink. Water Quality Results Before installation, my tap water measured 176 ppm. After installation, it measured 70 ppm, because the ALK filter adds beneficial minerals back into the water. After one week, I performed a 14-parameter water test with the following results: Hardness: 50 Chlorine: 0 Iron: 0 Copper: 0 Nitrate: 0 Nitrite: 0 Calcium: 0 Total Chlorine: 0 Fluoride: 0 Alkalinity: 40 Carbonate: 180 pH: 7.5 Lead: 0 Bacteria: 0 Overall, the results are very reassuring. What I Would Improve I would like to see better filter replacement indicators. The current system for tracking filter life is not very informative. A clearer indicator or built-in reminder would improve the user experience. Overall Impression I am satisfied with this purchase. We drink this water daily, cook with it, and wash food with it. So far, the system performs as expected and gives me confidence in our water quality. Read more
The unit work great. The water is clear with no Ded taste. It was very easy to install. Following the provided instructions made the installation quick and easy. However, it is very important to follow instructions exactly to endure proper installation. Read more
Installed for one year. 4 letter word sums up our experience LOVE it. No more bottled water. Enjoyed the quality so much we now have 3 devices on it 1. Low pressure sink faucet we use to refill containers, espresso machine, and Keurig 2. I added a float system to our GE Opal 2.0 counter nugget ice machine. Recent deep clean of Opal had “0” calcium and mold inside. Which is unique for most Opal machines 3. Whirlpool refrigerator. It required adding. A 1-liter pressure tank seen to the left of the filter system. Total installation time was about 4 hours since I mounted it in our utility room and ran water lines to the 3 areas. I do have a salt based water softener. All extra material I needed I purchased from Amazon and I was even able to find a faucet dispenser to match our existing sink faucet. The money we save monthly on bottled water and ice purchases more than offsets filter replacements and avoids plastic recycling. Read more
I have been so happy with this reverse osmosis system and it was pretty easy to install the system. I only need a tiny bit of help from my husband🙄. The biggest issue was making space under the kitchen sink which I have too much stuff under there anyway, but overall very pleased with it and it REALLY doesn't take up much room at all under the sink. There is also a disposal under the sink too, so was fairly easy to get it installed with disposal kind of in the way. I drink the water everyday and it has a pH of almost 10, so this is exactly what I wanted, and I did a ton of research before deciding to purchase this one. I didn't realize that 3 of the filters are good for 6 months, and the 4th, the "RO" filter is good for 1 year... So now that I'm familiar with which filters need to be changed, and WHEN they get changed, everything is great! I ordered the 3, six month filters, 6 months ago, and somehow I chose a set of three that did not go to my machine... however two of them did. I called customer service asking what filter goes where, as I was confused, and they sent me out the correct filter at no additional charge to me, and they did NOT require me to return the one that didn't go to my system. So I am very pleased with the customer service aspect as well. The water tastes great, and I keep a gallon of cold RO water in the fridge at all times, for this is the ONLY water I drink. Not only do the "humans" drink it, but also all of our pets, baby silkies, and our cat Phoenix. The spigot that came with the system is great because it's tall and you can twist it over to the side and put a big pot under it and fill it up without holding it. The flow rate is pretty fast however filling up a large pot to boil potatoes can be a couple minutes, it's great that it has the tall faucet so you can fit a gallon jug under it as well as big pots and pans, so you don't have to hold them while it's filling up. Overall I give it five stars 😁. Thank you so much SimPure! ❤️ Read more

The Best Tasting Warter Ever. The only Water filter System you will ever need. After years of using a standard carbon block system, I finally made the switch—and I’m never looking back. This is hands-down the best water filtration system you will ever need. The water is incredibly pure and tastes almost like high-quality mineral water. There is honestly no comparison to anything else available. Plus, the installation was very simple, and the filtration-to-waste ratio is excellent. It is very affordable and has low cost of replacement filters. System perfectly fit under my sink and it took me about 30 min to install. Highly recommended! Read more
