Steven T.Steven T.: This is the best company I have every worked with. When I called headquarters I talk to Michelle. She was very knowledgeable and walked me through all the steps! This unit does 300 gallons in 24 hours. My water level tds from the city is 770. After being filtered it’s reading about 4Tds and after 6months it’s reading 10 tds. These units are awesome!

DragonDragon: I bought this system for my business over a month ago and just now finally got it to work properly. The main issue I had was that the instruction manual (image attached) is wrong and showed to hook up the tank hose and the faucet hose backwards so that the water flow was going through the post carbon filter the wrong way. This destroyed the post carbon filter. Nick from ispring helped me resolve this issue by sending me a replacement post carbon filter, he even sent me three RO membranes to use as back up after mine are used up. I suggest speaking with a ispring rep rather than following the instruction manual to avoid breaking your post carbon filter as I did.
After resolving my problems I am happy with the system. I have a flow meter hooked up to the faucet which allows me to see exactly how much the pump on the system really helps. Before the pump turns on (without the tank) the water flows about .15lpm when the pump turns on it flows at 1.15lpm. So the pump actually speeds up the flow by a whole liter per minute. I am using this to fill large containers of RO water so the pump is a great feature. This system brings my TDS from 34 down to 1. After sitting overnight the TDS...

david prior: I purchased my iSpring RCB3P RO filter system to put on the front end of my mist cooling system to reduce the negative impacts of the hard water on the mist cooling pump, the nozzles, and all the furniture, glass, tile, and stone in the area under and around the mist nozzles.

I hadn't noticed that at time of purchase there was a note the said "Condition: Used - Like New - Item will come in original packaging” albeit there was about a hundred and some dollar price difference compared to the the typical price posted on the Amazon website.

When I received the RO unit the box was in decent shape, no outward signs of rough handling. However when I unpacked the box I started to get worried as the RO membrane housings were all shaken loose and dangling from their hoses. The top carbon filter was hanging from one hose and the tee on the other end was snapped clean off. The RO membranes and the pre-filter cartridges were brand new and still in their sealed wrappings. But suffice it to say I could not run the system in that condition.

I contacted iSpring customer support through the link given on the Amazon web site. The next day I received a call from Nick at...

Amazon Customer: This product clears up our water that has sediment in it. It makes is like distilled water! Would recommend if you have cloudy water. Nick was great with recommending the proper filter products for re-order and answering my questions.

Deanna: This isn't our first RO system we've purchased from iSpring, we put the same unit into our previous home and absolutely loved it, so did the people we sold our home to!

When we received this system we noticed that there were a few connetions that were needed and absent from the box, we contacted Josh at iSpring and he was so helpful, he even went so far as to send me a rush parcel filled with everything I would need to get the system installed and operating right away. He was amazing and incredibly helpful with information and support for everything we needed. I can't say enough about iSpring, their product is of the best quality and I would definiately purchase this unit again, it will always be an esential part of any home we own.

lilylily: We purchased the iSpring RCB3P Reverse Osmosis RO Water Filtration System, 300 GPD system in 2017. Initially there were damaged parts from shipping but the parts were promptly replaced (Nick from customer service is awesome). Our water was high in sodium and this system reduced the TDS from 450 to under 30. Prior to this system I was buying filtered water in 3 and 5 gallon bottles which was running me over $300 a year so this system has paid for itself multiple times. The system has worked flawlessly since 2017. We couldn't be happier with this unit.

The frame of the unit is quite hefty and the motor, pressure gauge, and other electronic items appear to be installed well. I will update my review after I am able to test the unit.

This unit cost over $500.00 so the initial issues are very disappointing especially since I have no idea how long it will take to get the broken part.

1/16/18 Update
I sent iSpring an email via their Contact Us option from their website late at night after posting the above review.. I received an email from one of their representatives (James) the following day. He has been working with me to resolve the broken Inline Carbon Filter...

Gerald Henton: Very good price
affordable shipping
arrived quickly
comes with booster pump
has a pressure gauge
water quality appears very good

not really a whole house filter RO system more like a really big fountain setup
install manual was all but useless, was generic & for smaller system
you need to add a pressure tank
all hook ups and fittings were 1/4 inch plastic making it difficult to adapt to household plumping
1/4 inch lines restrict water flow

I have a farm with a well, water is good except I have about 2500 ppm dissolved solids and need a RO system to remove them. I managed to adapt this to provide water to kitchen and hot water. I added a large pressure tank and a booster pump. The RO put out about 34psi on its own, not enough to have a decent shower, as flow drops. I added a 20gal pressure tank to act as a reservoir. and a booster pump. The dissolved solids is a fancy was of saying salt. This was corroding the plumping pipes and fixtures. It was also destroying hot water tanks.
