Style: Instant Hot Countertop RO
This is a great unit if you don't want to mess with an under-sink model. I previously had an ispring under-sink purifier, but moved to a new house with very little space under the sink and opted for this one instead. It's slightly less convenient than just being able to pour directly from a faucet on the sink, but the hot water options are nice to have. I feel like it balances out. It's also WAY easier to change the filters on the countertop model. The water reservoir is easy to refill, it has a nice big handle that makes it easy to move around even when full of water. The water tastes great, our tap water has a lot of chlorine, but the filters seems to take it all out. I actually did have an issue with my purifier, it stopped working after a few months, but iSpring sent me a new one, the process was very easy (just make sure you register your warranty!). John at iSpring provided excellent customer service.

Style: RO System with Pump
We went with an RO system because we wanted the next level up for purity. What they don’t tell you is you need an electrical outlet in the vicinity of where you plan to install it. Also your water pressure needs to be between 30 and 90 psi. And the actual width of the unit is 9.75” with the tubing protrusions. This installation is for a handyman, which I am one. I spent 2+ hours just reading the instructions and making sure everything was good and I knew what I was doing before I started. Actual instal time was another 2+ hours. RO water tastes almost like distilled but has a spring water freshness about it. We are still getting used to it. A pinch of sea salt helps. The tank holds about 2.5 gallons. Since you rarely use more than a glass or a gallon at t time, the flow comes out real nice. It takes a while to empty out the full 2.5 gallons. So far we are thrilled with how it works and the quality of the water. Haven’t checked on prices to replace 3 filters every year and a forth one every 3 years. I would recommend this system but if you are not a home handyman I reccomemd hiring one to do it for you, not a plumber, to expensive

Style: RO System with Pump
My primary goal for this RO system was to get water as pure as possible (as low of a TDS reading as possible), for the uses of: humidifiers, watering rare plants, medical uses, drinking, cooking. I was previously buying (and sometimes making) distilled water for my humidifiers and plants, which was extremely expensive and a real pain. Distilled water has TDS of 0. My tap water already was excellent at a TDS of about 27, but with this RO system I was able to achieve an output TDS of just 2. That's ridiculously low, almost as pure as distilled water. This was exactly what I had hoped for. I believe it took a few days for the TDS to drop to that level, perhaps due to remnant particulate matter exiting the filter canisters (that's my theory). I was drinking and cooking with tap water before, but now I use RO. It tastes so clean, no chemicals, no odors, like a mountain stream, and it's nice to know there are less toxic chemicals and pathogens in it vs out of the tap. I was worried after reading a few reviews of flood damage due to a leaking system, but when I realized the kit now comes with a "leak stop valve" it put my mind at ease a bit. This valve will sense water leaks and then shuts off the water coming into the RO unit, thus limiting the damage / amount of flooding. One of the photos on this review shows the leak stop valve - it's a gray piece of plastic with the red supply hoses going in and out of it. Note that my leak stop valve did not have any locking clips in the bag with it, but iSpring does include a bag with extra parts, so I simply took two clips from the extra parts bag. Despite the leak stop valve, I went a step further. I have a Ring security system. I purchased a Ring flood sensor and placed it under the sink next to the RO system, so I will be notified if there is a leak. The sensor is shown in one of the attached photos (it's the white disc shaped thing). I got the system with the booster pump, and with how clean my tap water already is, it flows super fast through the system. It will completely fill an empty tank in about 40 minutes. I can get as many gallons of RO water per day as I can possibly use for every purpose. Now I have essentially unlimited pure water for all of my uses, and don't have to spend money and time with distilled water. The pump is pretty much silent. I can hear it click on and off but that's about it. By the way, I did not have an electrical outlet below the sink, so I drilled a hole through the side of the cabinet near the back, and ran a small extension cord from the pump up to an outlet on the wall above my washing machine. I purchased an additional ispring tank to expand storage capacity, and set up a Tee fitting which splits off to both tanks, with ball valves in each supply line. See attached photos. I can turn off and remove one, or both, tanks if needed for maintenance / access under the sink, replacement, etc. If I turn off and remove just one, the other tank stays functional. Figuring out the layout / position of the unit, hoses, tank, etc was probably one of the more challenging aspects of this project. It took some planning, thinking, and measuring, and I was extra cautious every time I made a cut in the 1/4" hoses (measure twice, cut once, as the saying goes). By the way, pro tip: Use PVC cutters to get a nice clean 90 degree flat cut on the 1/4" hose (assuming you have good PVC cutters with a flat/square jaw under the blade). I installed the waste water drain line several inches above the p-trap on the sink drain. I must have done it just right because I cannot hear the draining water at all. Make sure to put the drain line above, and on the clean side of, the p-trap (not below it on the back where the sewer gas is). The included faucet is nice. I had to drill a hole in my utility sink, which is some sort of composite material. I used a HIGH QUALITY hole saw blade (Bosch brand) and use some cutting oil on the blade and sink to lubricate it. Took it slow and kept clearing away the chaff and putting more oil, and the hole came out perfect. Since my sink is very deep, when I fill my gallon jugs with water, I slide a vinyl hose over the tip of the RO faucet and have the other end of the hose in the water jug. Then I can walk away for a minute while the jug fills. There were a few minor negative things I will point out. The first issue, the instruction manual which came in the box, and the video I found on YouTube, did not have exactly matching instructions. There were a few differences in some of the steps (I don't recall exactly what they were as this was some time ago). I reviewed it all a few times as I went and then did what made the most sense to me for my particular situation. The second issue, there is not really any way to know how tight to make the canisters onto the housing with the wrench. You just have to guess and make it very firm but not too firm. It would be nice if there was some better way, for example a marking on the housing and canister which line up when they are precisely connected. The third issue, due to how the system was set up and positioned under my sink and how everything was during installation, it was basically impossible for me to flush the canisters using the described methods. I had to unhook most of the system, pull it out, then luckily I had a spare piece of 1/4" hose from something else, which I attached to the part which lets out the flushed water, and aimed that into a bucket. I don't recall the details exactly but I do know it was slightly confusing and a bit of a hassle. There may have been other issues but nothing is sticking out in my mind right now. As noted by another reviewer, it was slightly confusing at first to understand how the storage tank line works, since the water goes in and out of the same line. It took me a bit to register that. One other thing which isn't a deal breaker but is a bummer: Filling gallon jugs takes a while, and I often fill three at a time. It takes about a minute and a half per gallon. I wish there was a way to get the water out much faster. I use a lot of water for humidifiers and plants, and it's a real hassle to slowly fill up the jugs and transfer the water every day. It would be awesome if there was a tank with a larger outlet valve which could be used with a larger diameter hose, maybe with a smaller outlet on the side to go to the RO faucet, and the larger diameter outlet could run a utility hose or something. Another positive: The customer service was great. I usually received a reply in less than 24 hours. The info was clear and helpful. They were able to answer all of my questions and addressed my concerns, and went the extra mile on a few small things. Even though the kit comes with extra gaskets, I purchased additional extras, as well as a multiple year supply of filters. Use a TDS meter to periodically test your tap water and RO water to keep an eye on fluctuations. If the RO water goes up in TDS significantly, there may be an issue, or if it goes up slowly over time you may need to do some maintenance. A tip for using a TDS meter: Make sure you have distilled water, with a TDS of 0, to rinse off the TDS meter probe after testing each water source (for example after testing tap water, before testing RO water), and ESPECIALLY after the final test before storing the meter. You need TDS 0 water to rinse the probe off so it doesn't skew future readings by leaving impurities on the sensors.

Style: RO System with Pump
I like this product because it does a good job with filtering the water. our well water had a TDS reading of 420. it is now down to a reading of 23. i installed this unit myself and i will share with you some of my troubles. Problems i Had: Upon first inspection i noticed that the carbon filter which attaches above the membrane had a clip that was broken. since i didn't want to send the unit back, i just dealt with it and secured it into place with some tape. Step 1 has you connect the cold water valve. let me tell you, this valve is garbage and did not fit on my cold water line. once i got the proper adapters setup and had the connector installed, it leaked all over the place. i ended up throwing it away and i went to home depot and got a T valve and installed it with that. i just had the rep from home depot help me find parts with the specs i gave him. i also purchased 50FT of polyethene tubing because i wanted to mount the unit in my basement. the tubing i purchased worked great accept for one aspect. it leaked out of the drain saddle. reason was because the provided waste tubing was a little thicker than the standard tubing. i just used an adapter i purchased at home depot to connect the 2 lines and it was fine. the good: water is clean, TDS is low, Tastes great. no problems there. the bad: i think the manufacturer could do a better job of quality control. the cold water adapter was junk and definitely not worth my time as i wasted nearly 2 hours with it. the filters work great but the clip to hold the carbon filter had to be taped into place, this was because it was broken when it arived. not sure who to blame for that. all in all, its a great product that anyone can install if they aren't an idiot. just make sure you turn your water off while you are installing and use common sense.
