Review: Review – Why I Chose This Model - 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.
Review: Good Product and Reasonably Priced - I’ve been using this system for a little while now and overall I’m really happy with it. The water quality is the biggest win. It tastes clean and crisp and way better than what I was getting before. No weird smell or aftertaste, which was important to me. Installation wasn’t too bad and it fit under my sink without a problem. Everything feels pretty solid once it’s set up. The only downside is the flow is a little slow. It’s not a deal-breaker, but if you’re filling up something big you’ll notice it takes a bit longer than expected. For normal use like drinking water or cooking, it’s fine. Customer service was also really good. I had a couple questions during setup and they were quick to respond and actually helpful. For the price, I think it’s definitely worth it. If you don’t mind slightly slower flow, it’s a solid system.

### ⭐⭐⭐⭐⭐ Simple to install, with tank for fridge 180 to 0 TDS, PH neutral
*by A***A on June 13, 2024*

You don't realize how dirty your water is until to you go RO! Recently replaced the refrigerator, but noticed the water didn't seem as "clean/fresh" compared to our old one, also reading reports from out water company although inline with Fed but real close, decided to get RO filter for drinking and fruit/veg final washing. Added the tank as it is connected to both refrigerator and sink on opposite sides of the kitchen. The pipe and fittings it comes with are fine for under sink installations however I purchased extra 1/4 (RO) pipe and fittings (BPA PFAS free they say). Was originally going to install either in basement or closet next to fridge. However, as the fridge needs to pulled from it's cubby out to prevent damaging the doors on the wall, there was enough space to put everything behind it, and also prevent the fridge getting pushed back. (Thanks to the tank). Ran the sink pipe and waste through the basement. Cable tied clean to a cold water pipe to help it cool, connected waste into a vertical sink pipe, will add a T with a shutoff (winter/summer) later to collect waste in outside drum for garden plants (non edibles). Fridge connection was easy as it was already a new plastic pipe so just cut it and added an extra shut off Removed fridge filter (Add TSD to RO - even as new it only took out 10 -20 TDS prior) Fridge works perfect, ice is crystal clear. Before you buy and install: 1) Figure out where you want to put it, it needs a good amount of space, and room to drop filters out. 2) If you can find room for tank, get it and connect the fridge for ice, otherwise what's the point 3) Before connecting pipes make sure they are clean cuts and straight (a very sharp knife works) 4) Make sure you have enough pipe and extra fittings if you install anywhere but under sink(with fridge next to it) 5) FLUSH completely for 20 mins, If you have extra pipe, it might take a bit longer to clean it out (Keep fridge water shut off then flush a few glasses), 6) Check PH and TDS before during flush and after this way you will know it's working and when ready to drink - also smell, parts may have oils from manufacture, keep flushing until it's totally odorless. NOTE: RO is a slow process, the faster it is the warmer the water gets. If it's too warm or too high a pressure it damages the filter membrane. Be patient. We wash all raw veg with faucet water then rinse with RO. For cooking we use RO (sometimes we forget) Complaints from kids - It has no flavor (Chlorine) - add some mint, basil,rosemary - Sink outlet is a bit warm -that's what ice is for For a small investment, feel this is a good health choice. We drink a lot of water (128oz each a day minimum). Most bottled water is RO sometimes with stuff added, (or plastic &chems) this is cheaper and removes pfXs etc. UPDATE 3 MONTHS: 1) No more 'SWAMP WATER' in refillable water bottles. Kids are notorious for only cleaning water bottles when the water is swampy (their definition). This is quite a concern - whatever bacteria was making it through the faucet tap water & fridge filters is no longer present, water bottles remain clean for a very long time. 2) In warmer weather, water at sink is a bit warm so we add ICE when doing final rinse on lettuce 3) Spherical/craft ice on refrigerator slightly off shape (has an added bump on one end), this is due to water pressure. Its a cosmetic thing (a little amusing TBH) Some people have this regardless of filtering!
