iSpringCRO1000 4-Stage Tankless Commercial Reverse Osmosis Water Filtration System, for House, Restaurant, Small Business, and Light Industrial Use,1000 GPD High Flow, Upgraded Size Filters

The CRO1000 has been a game-changer for my home water filtration setup! Every weekend, I used to spend time cleaning just under one liter of precipitated municipal water contaminants from the boiling tank of my Durastill water purifier. However, since integrating the CRO1000 into my system, this tedious chore has become a thing of the past.The division of labor between the CRO1000 and the Durastill appears quite effective. The CRO1000 takes the first pass, removing contaminants larger than its smallest membrane opening. This pre-filtering has measurably reduced the burden and increased efficiency of the Durastill. The Durastill treats what doesn’t boil below or near the boiling point of water, and VOCs like benzene and toluene. As a result, the Durastill’s boiling tank hasn’t required cleaning in over a year!The CRO1000 is not only efficient but also easy to install and maintain. It’s a reliable workhorse that has significantly improved the quality of my water and the longevity of my Durastill purifier. If you’re looking for a robust reverse osmosis system that works seamlessly with other purification devices, the CRO1000 is the way to go. Highly recommended! Thanks much John!

So far so good I was missing the bolts and screws but Julius @ customer service reacted quickly and they have them en route to me now. I have the system set up for testing and with the Ispring booster pump it's producing water faster than advertised all said for this initial use I am very happy with the product.

This commercial quality R.O. water system is just as advertised. It provides us pure chemical free water without all the additives that are put in today’s water that is provided to your home or business. It was as easy as anything to install and requires little to nothing in maintenance. The only maintenance required is changing the filters as recommended according to their guidelines. Even replacing the filters could not be much simpler. Another bonus that comes along with this water filtration system is the tech. Support. We had a couple of questions which required contacting iSpring tech. support. We called the company and were completely surprised that we were able to speak with someone that speaks English and is located in the United States. Our call put us in touch with John and he could not have been more friendly and professional. I highly recommend this product and company and praise John for his complete knowledge and understanding of their products and helping us when we had some questions.

Most impressed with this system! I am not using the system as suggested. However, the results this system has produced have been surprisingly successful! I have taken well water with a TDS of near 1700ppm down to approximately 300ppm. The system has accomplished this with an incoming PSI around 45-50. I have not calculated the rate of production of clean water at this PSI. It is a constant flow comparable to what an under the sink RO flow rate would be filling a glass. If I trusted the plumbing feeding the RO I would crank it up but the CRO1000 is producing a good amount of filtered water at a PSI well under what it calls for. Customer service from iSpring or 123filter.com have been extremely nice and helpful with my application. Nick specifically helped me the most and had no problem assisting me with my application. 10/10 would recommend this product and company to anyone that has issues with their water!

Well made with easy to understand instructions.

The unit is making excellent RO water, about 1 GPM. I suspect the lower production is because I am feeding it cold well water. My TDS going in is about 2000ppm, water coming out is a spectacular 120ppm.Pros- Excellent water quality, good price point, uses off the shelf filters and components mostly.Cons- Assembly is a little difficult, instructions could be a little clearer. Unit arrived with some minor damage to the 3/8' fittings in the cabinet but iSpring shipped the part right away

I purchased the system to supply potable water to my residential kitchen ice maker, refer and pot filler. Our softening system left a large amount of Sodium ions in the water. It is crystal clear and tasteless in the kitchen now. This system is plumbed with 3/8 tubing, so it does not have adequate flow without a booster pump- unless you have really high domestic pressure on your well tank. I decided to opt for an alkaline post-filter to correct the pH and had a problem with the last filter leaking. After speaking with Julius in Customer Service, A new filter was sent and all seems to be working beautifully. I am very happy with the install. The filter assembly is designed to rest on the floor with casters, but was easily adapted to a wall-shelf with anchors at the top. Pressure/flow is low due to the tight R/O membrane. If you want consistent flow, be sure to get an accumulator tank. 5 Gallon works great!

I would highly recommend any and all ISpring water treatment products. I have many of their products and they have all worked great and have solid construction.I used this CRO1000 system as part of a custom point of entry RO install project on a 4 story beach house with 5 bedrooms, 7 1/2 baths, and a 5000 gallon pool. I also used Isprings whole home UV light filter, pre-sediment filter, RO booster pump, and a Rockwell 250gallon holding tank, a well pump, and other misc parts. All in cost was around $3.5-4k. Now the entire house runs on RO water which not only tastes great and is far better for your long term health, it protects all of the homes appliances/plumbing from degradation, stops build up of scum in showers and toilets, and now acts as an emergency water reservoir that can be used even when the power is out. Having perfect drinking water from every outlet in the house is super convenient as well.A few months post install I had what seems to be a premature failure of the UV LIGHT BULB and O-Ring seal on the regulating valve. luckily NICK from customer support responded to me right away and was able to cover the issue under warranty and send out new parts immediately!
