This product was easy to install and works perfectly for what I need it for. Thanks to Nick for helping me!

My buddy Nick asked me if I like it. Here is my answer.The water taste is exceptional, and I am upset that have not purchased the system years ago. I like the compact design so it fits under sink without any issues. The lack of tank is a great plus since I know the water is always fresh. The productivity of the system is decent, so it fills my coffee pot about 25% faster than my refrigerator filter. I am happy with the purchase and plan to buy another unit for my second home.There are some CONS that I had to mention: 1) installation instructions are inaccurate is a way that they do not instruct user of three pre filters that are incorrectly installed. These filters are still packed in plastic, but are installed in the systems as if they are ready to use. Instruction does not contains step to disassemble filters, remove wraps, and place them back. So I had to find it in a hard way, after pressurizing the system with water and realizing it does not work. So I had to cut water to the house to discharge the pressure and fix the issue.2) the system has notable delay before pump starts, so when you want to fill a glass it takes about 15 seconds during which water flows slowly before pump kicks in. I am used to it now, but still consider this an issue with engineering design.3) the system has no monitoring gadgets that would measure water quality and alert you when it requires attention. If this is optional product add-on I would like to see it.

This system really works. One year on and it’s working without any issues. Thanks Nick. I added a 300 gallon holding tank and booster pump so my whole house is RO. My total dissolved solids (TDS) was 640 before installation. Within a few minutes of operation my TDS was, and still is, 7. My bottled water tests about 15!

Im on well water and have a prefilter and softener outside. This beautiful tank-less RO system installs easily, makes very good water. Water quality is excellent. My estimate of the waste ratio is close to 1 by 1. It does so at low pressure and a very affordable pricing. Definitely recommend it.

I have used many reverse osmosis systems. This system is so far the best. These are the reasons.1. The so called side flow technology produces 1:1 waste ratio that I have never seen in any other models2. It is rated 500 GPD and it does produce close to 500 gallons a day. I evaluated it at 60 psi, 65 F degree, and 280 TDS. I collect both RO water and waste water with two 500 gallon tanks.3. It is solid and sturdy. The lightweight metal frame stands by itself. It looks it worth $1000 a piece.4. It uses standard filter cartridges that can be found everywhere at fair price.5. The electric pump is quiet, responsive and does the job. I have run it in full capacity for over 3 months and no issue whats so ever.6. The installation could not be easier with only three John Guest fittings to be connected on the same side.The only thing I dont like is the pre-filters are 10 inches long rather than 20 inches and subject to be replaced more often, although that can be supplemented by an one or two stage whole house filter. Considering its compact size, it is really a trade off.So, this is so far the best RO system I have ever used. It fills up a 5-gallon jar in a couple of minutes. What an achieving experience! It takes TDS from 280 down to 15. It works well for my large reef aquarium and indoor hydroponic system but I believe it is suitable for both home and business use. It is a fine machine that I would recommend to anyone.

I waited to write a review because I wanted to test it for at least 2 months. This product is the best one at a very reasonable price. The TDS from city water was 135 and after filtration is 4. Easy to install except the direction of the top cartridge. would be better if the top casing had direction arrow. Just bought a 2nd unit. Have not measured the waste water but the ratio seems to be around 1:1. Even if it is little more still best compared to other systems. I am using this systems for my automatic carwash.

We live in the Dominican Republic where even the city water is not so good so we had a whole house (+2 apts.) and animals using a filter and UV system for over 15 years. We have not had any city water for over 18 months now and in severe drought. We also have rain water systems to collect but with no rain, no water. Water trucks have over tripled their costs and the water that they deliver is from one of the most polluted rivers around. You DONT want to know what we found when we cleaned it.We finally put in a well and hit water at 30 feet. We are on the Ocean so expected some salt but hit good water above sea level. The aquifer is mainly in petrified coral so very high in calcium. Everyone here has 3rd world septic systems so that also added to concern. But the water was OK for the lawns (aka extra pasture), gardens and horses. Word got around about my well and in 2 months, at least 20 wells drilled within 1/2 mile. The well water became unusable for anything as many went too deep and let the sea water inter as the fresher water was sucked up. We also noticed a very bad algae/bacteria problem in our pools and 2 cisterns.After much research and questions to Helen @ iSpring, we bought this unit. (THANK YOU HELEN!) We concentrated on what we had and what we needed to accomplish. Electric is also very dirty here so we are 90% solar with a good inverter and battery systems. Importing anything is expensive to ship and the custom taxes are outrageous. We needed to get this right the first time. Not worth shipping it back.Since most of our water systems are in a dedicated room, it was fairly easy to get up and running in a few hours with no real expertise needed. Advanced planning may be very important.1. A couple of changes so that the well is dedicated to this RO system.2. Well water goes through a de-scalar. (we already had so we just moved it.)3. to an old sand filter that we cleaned up.4. to a UV sanitizer that we already had. (I didnt want the bacteria and algae getting into the rest of the system. Though the RO will handle some/much/?? it may not be able to kill and separate all.)5. 30 gallon pressure tank equipped with gauge, well pump on/off pressure switch, tank drain and connection to the RO.6. Followed or figured out the RO system and hung it on the wall. (instructions are very poor so it took awhile)7. New elec. serge protector mounted. Shelf for filters.8. The RO fresh water line goes directly into our non-pressurized cistern. No other pump needed.9. Waste water run into PVC drip pipes into the gardens. No other pump needed.10. Prior to the unit arriving, we transferred around 7,500 gallons from this cistern into our second one to go in and scrub/sanitize it. Lots of algae (and other stuff that you dont want to know about.).11. Turn on well pump, fix a couple of leaks and open valve to RO and plugged it in.12. Being that our cistern my have other contaminants leach in or I need trucked water added, that independent system also has its own filters and UV.Observations:1. Our 1 hp well pump will only give us around 65 psi while the best production would be at 75psi. (or higher?) I set my well pump controller at 42/62.2. At that pump settings, I was getting 540 gallons per day.3. Though I have not had the water tested yet, It is clear, no smell and tastes great.4. The motor is very quite.5. I have had NO issues in the week that I have had it running; 24 hours every day.6. Electric usage is not a problem with our systems.7. Waste water is doing great with my plants and even that is a lot cleaner.8. Filters are available and good prices.I have read the Q&As and comments and thank those that have posted and most I agree with. Again to Helen.... THANKS for your support @ iSpring.After just a few days, we are very satisfied with this unit. We will give it a couple more weeks but Ive already picked a spot for a second unit to be mounted right next to this one.(the name that appears as the author is my wife... lol)

I have had my system for approx. four months. It is perfect for our entire household needs utilizing a 300 gal holding tank. Yesterday I noticed a leak in the booster pump and found the unit to be non functioning. This morning I called ISpring and spoke with Helen in customer service. A replacement was shipped immediately with no hassle. The fact the unit has performed exceptionally well and the customer service will keep me coming back for all my RO needs. I also own a 75gpd under the sink unit from ISpring, very fine system.

I must say Im impressed. Our well water has a measured TDS of over 4500PPM untreated. We were running this through several filters and a Culligan water softener and it was still in the 3000+ range. I have a 2500 gallon tank for the well water and from there it goes into our softener and then to the house. I connected this RO system to the incoming water prior to the tank and it is giving us water that is reading 70PPM! Ive reduced the amount of softening significantly (5X less salt usage) and the water coming out of the tap is so "soft" that my wife is complaining she cant get her hair rinsed of shampoo. As for the claim of producing less waste water, I dont know. It seems to just from watching the 2 hoses of the device, but I havent actually measured the output of the waste compared to the treated water. All in all this is the best $700 Ive spent on the house. I might even be able to wash my car now.
