Best Tasting Water !
I recently installed this tankless under-sink RO system, and it’s been a fantastic upgrade for my home water quality. The multi-stage filtration removes a wide range of contaminants while the alkaline remineralization adds back beneficial minerals for better taste and balanced pH. The built-in UV sterilization gives extra peace of mind by helping to eliminate microbes, and the compact, tankless design saves precious space under the sink. Setup was fairly straightforward, and daily use delivers clean, great-tasting water on demand. A highly effective and efficient choice for anyone serious about pure drinking water

Simple to install, with tank for fridge 180 to 0 TDS, PH neutral
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!

Alkaline Reverse Osmosis System
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! ❤️

Great product but bit noisy
The water filter is great, easy to assemble. It took me around an hour to finish the installation. I opted for alkaline one and the water tastes great. I find it bit costly for the price. Also, the filter is bit noisy, tried putting insulation between the wood and filters but still when pump starts, it makes a bit of noise. Another thing is, the UV filter, it's too small and don’t know about it’s effectiveness. Overall happy with the product so far.

Just installed it with my husband yesterday. Was not complicated to hook up at all. We didn’t have enough space under our sink so we just used the cabinet next to it and ran the lines through a hole. We had zero issues with the install it was fairly easy with two people. I bought a water tester and the water tested successfully at 0 PPM after I ran it for half an hour as the instructions said. I checked the tap water too just to make sure my device was working and it tested at 36 PPM. The pump is extremely quiet in my opinion, with kids in the house I don’t even notice it unless I open the cabinet door intently. The side faucet it comes with it nice looking and slender. Overall I’m very happy so far with it and I’ll have to continue to test the PPM as the filters age, the little device is only $10 its probably worth getting for maintenance purposes.

My husband and I have been drinking RO water for over 40 years and just recently moved into a house that we could put in a unit under the sink. This unit is absolutely wonderful and easy to use.

I purchased this product because Simpure is based in Seattle, USA. Unfortunately, the experience has been disappointing. Within two months, the small water tank began leaking, which flooded my basement. In addition, the water flow is noticeably weak compared to what I expected. Updated: I received a new tank after contacting customer support -- all good now.

If you are thinking of buying one I would! It seems to work very well and the few issues I had were taken care of by the best customer service I have had in years. Anything wrong new replacement parts are shipped immediately without question .... truly excellent!
