The best tasting water

The taste of this filtered water is the star of the show! Its so fresh and has no weird aftertaste. There is a decent amount of pressure from the three gallon pressurized water tank. A simple change of the filter every minimum of six months is all thats needed for fresh tasting filtered water. Hubby said the installation was such a breeze that he wants one in every room.

A standout product and well-worth the investment

The iSpringRcc2AK is a remarkably well designed under sink R? system that delivers crisp clean mineral-balanced water with a smooth naturally sweet taste all while fitting nearly into tight cabinet spaces without feeling bulky or intrusive. Its upgraded 200 GPD capacity keeps up effortlessly with large households or office use and the sturdy materials from the reinforced housing to the metal faucet feel durable and leak-resistant with no drips or pressure inconsistencies even after heavy daily use. The six-stage filtration noticeably improves clarity and removes harshness while the alkaline demineralization filter restores a pleasant rounded mouthfeel that never tastes flat. Installation is straightforward thanks to the thoughtful layout and transparent first-stage housing which also makes stay quiet steady and reliably mess-free.Overall it��s a space-efficient high-functioning leak-tight upgrade that transforms everyday drinking water into something genuinely refreshing and premium.

No hard water

This filtration system works well. We use the sink for washing dishes and boiling water. I have a water cooler for drinking water. I like this for not washing my dishes with hard water.

Peace of mind knowing my water is purified and cle

We have well water so owning a reliable RO system is vital. This was fairly easy to install but highly recommend you watch the videos and read instructions carefully. Do drain the tank a couple times prior to drinking the water to get rid of impurities that maybe in the tank. The filters and tank do fit under the sink but do take up a fair amount of space. It comes with a water faucet that dispenses the purified water and it��s very easy to use. You will need to drill a hole next to your faucet if you don��t already have one drilled.

Love it!

This filtration system works great. It is easy to hook up and the water tastes amazing. We can ditch our stand alone water purifier freeing up space in our room. It does take up a good chunk of underneath the sink but we can still fit some crystal things and it is worth the space!

@ispring water system #you half to get one

I was really excited to get @ispringwatersystem hooked up in my house because we live in a town where the water taste really bad because I believe they are not putting enough chlorine in it amd it does have a smell to i thought with all the parts itwasgonna cereals hard to put together but it didnt take 30 minutes or so once me and my husband got started and it has 3 filters with a long lasting filterlife so you do half to change them out every 6 months maybe at the most and you seriously dont here anything under neath the cabinet so there is no noise at all overall the water taste like real spring water coming out of the faucet so no more buying bottled water for this family

Got mine and immediately installed it. I absolutely love this! It��s so easy to use and replace the filters. I love having it close to the sink too so no extra messes are made.

My must have home machine

iSpring Water System RCC2AK is a must have in our house. It is very easy to set up and the instructions were very clear. The noise is very minimum and I did not even notice the noise when the machine is on. Water quality is also a huge plus since the water is so much pure after being filtered by machine. It also saves me a lot of time by going out to supermarkets weekly and buy filtered water. Highly recommend.

Finally Clean drinking water from the tap

We live in north Texas and have hard water. In the summer months the water from the tap smells like you��re at the lake and tastes like you��re drinking it too. We buy bottled water to drink because the the taste. After reviving the iSpring water reverse osmosis we looked at our city water grade. It scored an F. Failed of 5 different chemicals. The iSpring water system took about an hour to install under our sink. The taste of the water is bottle water quality. Could not be happier. I wanna bath in it. I can only imagine how great it would feel on my skin and hair.

Customer Service solved our problem

We purchased the ISpring RO 6-Stage system and installed it at our cabin. The installation process was straight forward with the manual and color coded tubing. After installation we could hear water flowing through the system into the drain. We called ISpring customer support and spoke with Nick. Nick immediately asked if we used well water. When we said yes he noted that we needed to have purchased a system with a booster pump. He stated that he would immediately send us a manifold with the pump. The new manifold arrived quickly and changing out the original manifold with the new one was fairly easy. The system is now working effectively. We are very pleased with the product and customer service.

This was honestly kind of difficult to install but once getting it installed with the help of my dad it works great. I have a hard water issue at my home even in my kitchen sink and this has really helped that it makes it convenient.

A RO Alkaline water system at an affordable price

I��ve been considering a reverse osmosis system for a long time now. The health benefits always intrigued me but after my father was diagnosed with cancer I��ve been really focused on optimizing my family��s wellness. While we typically drink filtered bottled water I wanted to up my game. There are so many RO devices out there but I wanted something that was NSF certified- the whole device not just singular components. This met that criteria. I also wanted something inject enough to not take up the entire space under my sink as I don��t have a ton of room. This was so easy to install and we did so in under half an hour. The filters are seemingly easy to replace ANF this has remineralization for calcium and magnesium. What you really want to look for is the alkaline aspect that enhances the PH and reduces acidity. This iSpring offers all f that in one and combined I am looking forward to better heath for my family. (Do yourself a favor and look into the health benefits and disease prevention of RO Alkaline water)At this price point I don��t believe there��s a better long term health investment.

Pressure not as good as they make it out to be.

I just replaced a Clear Water Sanitech RO system we had for 10 years. I purchased the 200 which is upgraded for a larger family. The pressure on this system is nowhere near what Sanitech was and Im very disappointed. It a slow steady stream no real pressure at all! I went up to 9 pounds in the tank no change 8 pounds no changed 7.5 pounds no change. Slow steady stream no real pressure like the Sanitech system. I'm bummed out after install. But it works just not like it makes you think

Great company great products and amazing staff!

I just bought this unit. Sean was great help in helping me decide which system would be best for me. I have dealt with him in the past with a commercial RO system for my business.
