I had previously leased a water filtration system and my friend advised me to stop leasing it and just purchase one. Since I had a system previously installed, I didn't have to drill or potentially call a plumber. The reason for the 4 star is because the installation instructions are just terrible. You have to go watch YouTube and even that was a bit confusing (at least to me anyway). However, installing it, I am glad that I purchase this system. Oh and after you install it and flush out the system you might see these white flakes or bubbles in your glass. I was freaked out by that until my friend said it was air and it did disappear after a while.

Great system and the customer service helped me with an exchange as the first system didnt fit under my sink. Enjoyed working with them.Pricing was attractive.

Water tastes great. The spigot is somewhat fragile, though.

This is a great replacement for my previous water filter. Everything that uses this water (tea, coffee, water) tastes much better! We previously had (for many years) and Amway water filter that was ok but no big deal. But the replacement filter cost was ridiculous. After a bunch of research, I settled on this unit as the best one that does not use RO (due to the significant amount of water wasted in the process).I am very happy with this choice. Easy to install, works great and the whole replacement filter set is not that expensive comparatively.

Had this product for over an month now and I really like it. Water tastes great and installation was also pretty straight forward.

Great product. Using this system for my refrigerator water and ice. Love the taste of the water. This is the 3rd system I have purchased from iSpring.

Very complete system, right down to the teflon tape. Great instructions. I especially like the clear sediment filter bowl for the entertainment value of watching it turn brown from our nasty water. It was about $30 cheaper back when I bought it, which made it a steal..

Had a few problems with the system, but the company took care of everything. The system is in and working great. Thanks

I ordered this to replace my Culligan ROS system, which yielded great tasting water, however, the cost of filter replacement and waste of water over the years, forced me to look for a more cost effective method of filtering water. The only gripe I had with the iSprings system was the lack of pressure from the faucet that was included compared to my ROS system. I eventually swapped out the iSprings faucet with my Culligan faucet and "viola!!" the pressures back where it should be. The water taste is a tad less tasty as my ROS system, but Ive gotten use to it since I set the system up 4 months ago.

I am a General Contractor/Home builder. We originally had a RO system that provided us with excellent tasting water, but took up most of the under-cabinet and had to be sanitized with bleach at each filter change.. We dont have hard water and our tap water is drinkable but we wanted it cleaner, and the RO had intermittent leak problems. Could I find a system that would relieve us of the clutter , the maintenance, the water leaks under the cabinet, and still get great water?I decided to give the CU-A4 a shot. SO, Here goes what I didnt like, and then what I liked:CONS:1. The directions do NOT adequately describe how to make the water connections. To someone who has installed with these type connections it is an obvious "no-brainer", but to the rest of us.........Parts of the directions appeared to be for a different unit, and especially the section on installing the faucet, which was obviously from their RO system and was not anywhere close to describing the faucet enclosed. The faucet enclosed is an "air gap" style which requires a hole in your sink deck or in your counter of 1 1/8" minimum. The threaded pipe that will go through this opening is 1" in diameter. If your existing hole is anywhere from 1 1/2" to 1 1/8" the provided washer will work fine.2. While there was plenty of 1/4" tubing to do the installation, There are 3 colors of tube, red, white and blue. They provided plenty of blue and white, but not red, therefore I used white and labeled it red to make the job a clean install.3. There is no discussion in the manual of run-in time after completing the install. The water was barely drinkable after letting it free-flow for approximately 10 minutes as suggested in the notes . After flushing the system with approximately 15 more gallons the water was crystal clear and the flavor has become progressively better and better and has stabilized.PROS:1. The system IS actually easy to install when you have familiarized yourself with everything they have sent and how it will work with your existing plumbing and sink. AND you have purchased anything you might need so the system will integrate seamlessly.2. The snap-fit connections work great and do not leak a drop.3. Twist on replacement filters. How could it get any simpler???4. Takes up minimal space.5. The faucet is all metal construction.6. After initial flushing and after the first week of use (approx. 1 Gal per day)t the water tastes GREAT.As good or better than any of the bottled waters we have tested against.7. Every time I have called them (of course during business hours...duh...) they have been very responsive.So, customer service gets a nod.CONCLUSION:Well worth the money,Simple design and installGreat tasting waterNOTES:1.There is a review about salt taste. If you have softened water, then you may want to contact yourservice company regarding what is best to work with your existing system. At the very least do an internet searchon how softeners and filters can work together before purchasing this system.2. There are reviews that mention a 1/2" 3-way valve and having to buy adapter fittings. My system came with a 3/8 to 3/8" 3-way valve (which worked perfectly), so it seems iSpring has changed it to the more typical size.3. One reviewer gave 3 stars because this system does not reduce TDS and it cost them 10% restocking to return it.TDS is reduced by RO systems, This is NOT a RO system. iSpring does not claim reduced TDS. If you need reduced TDS...iSpring has a very highly rated RO system ( http://www.amazon.com/iSpring-RCC7-Reverse-featuring-See-through/dp/B003XELTTG/ref=cm_cr_pr_product_sims?ie=UTF8 ) for about $200.00.4. Most every review says the directions suck. I can attest to that. They do!Layout everything from the box, familiarize yourself with it, identify any problems with your existing plumbing. Take the 3-way valve with you to your local home improvement store and buy whatever you need.5. Make certain you have the correct tools to accomplish the install.6. For a water tight connection fit, remove the blue "horseshoe" clips and FIRMLY push the 1/4" tubing approximately 5/16" in to thecouplers until you feel it "bottom out", check the assembly by firmly pulling on the 1/4" tubing. Replace the blue clip.7. I made all of my tubing the same length and long enough for me to remove the filter manifold a couple feet from the cabinet to facilitate changing the filters when that time comes. The tubing is coiled and taped up (love that blue tape), and will be easy to undo and stretch out.8. I purchased an extra set of filters ahead of time, and store them right next to the unit.9. Instead of changing my filters by use of a calendar (such as recommended by the manufacturer, every 6 months), I will change them based on usage. Since we only use it for drinking and cooking, we likely will never hit a max avg of 3gals per day. Most filter manufacturers claim 6mos. is relatively equal to 1200 Gals. Therefore 3 gals x 365 days = 1095 gals. (1095 is approx 90% of 1200 filter life). That is when I will change mine, at about 1 year. You also can adjust your schedule based on this formula. If you use 6 1/2 gals per day, you will hit the 1200 threshold at about 6 months. Were you to use 10 gals per day you would want to replace the filters after 4 months. AND so on.If you dont have a basin wrench, get one from your tool store, (see images) Make your life easier.
