User Reviews

Review 1

This is truly a best-buy because of (a) the solid construction (b) the sink-top faucet is included (c) it comes with a custom diverter valve for water hookup and (d) plenty of tubing supply. See my hack below to improve the system by 10x.

My only issue is with the instructions. The overall system diagram is super tiny, and there are no images to indicate the names of the parts as they are being described in the instructions. I still don't know what the little blue horseshoe rings were for. I've installed 4 other similar under-sink systems in the past, so I had no problem. But if this is your first time, be sure to read everything through so you understand it all very well before starting. Plan to spend 2-3 hours+ overall, because working under a sink is cramped and difficult, no matter what system you have.

Two tips:
1. The tubing was difficult to fit onto the nozzle of the diverter valve. Soak the tubing end in a cup of very hot water for about a minute and it will go on more easily.
2. This 3-stage filter includes a sediment filter followed by two 5.0 micron carbon block filters. My prior system reduced particles to 0.5 micron which is superior (that's 10 times finer). To accomplish that, I simply ordered a 0.5 micron filter Pentek CBC-10 Carbon Block Filter Cartridge, 9-3/4″ x 2-7/8″, 0.5 Micron of the same standard size from another supplier and used it in place of the third-stage filter (Be sure it goes last in line with the flow of water!) Suprisingly this did not reduce the flow rate very much, which was a nice surprise. This gives me a premium water filter at a bargain price!

I originally order ispring RO system. But that didn't improve water. Returned it and tried this.
Water taste good and tests better then RO system, also there is no wasted water like the RO system.
No tank refill time.
This system filled my needs better then the RO

Build quality of the filter system is pretty darn good! Very solid filter holders, sheet metal bracket is a thick enough gauge, fittings and valves feel good and solid, and it was supplied with a full roll of pipe tape plus a TON of tubing (50 ft if i had to guess).

The faucet install was super easy, but it doesnt feel as quality as the filter system. The curved downspout wiggles in the base a little bit. Really not a big deal for the price i guess. The directions were very easy to follow- I got it in the mail and installed in an hour! The water comes out from the supplied faucet a tad more aerated than i’d like (if you fill a glass quickly, the water appears all white from the little air bubbles), but quickly dissipates. We did a taste test vs. tap- huge huge difference from our San Jose tap water. Bye bye Brita!

I purchased this product and was not disappointed.
I live in an area with mineral rich water and this product makes the water far better.
Nick contacted me promptly to follow up on my purchase to ensure that I was satisfied with their product.
No complaints.

I bought this system to filter water for a plumbed Keurig K150P coffee maker. The one filter solution recommended by Keurig is not that good. The filter quality or capacity is nowhere near the level that iSpring offers. It takes 2 stages to get the Chlorine taste out of the water. This 3-Stage system is outstanding. The water taste great and there is zero waste like there is with an RO system.

I believe this is one of the best water filtration systems on the market. The price is fair, the company has an excellent reputation, the filters are built well, and it comes with every piece and part needed to hook it up. Most systems require a few trips to Home Depot to figure out all of the parts, line sizes, etc. that is needed. This one comes with everything you need including a faucet! I personally did not use the faucet and plumbed directly to a coffee maker, but it is certainly nice that they provided one. I assume most will use this system for drinking water. It is also super easy to Tee one of the lines if you want to provide filtered water to more than one location (e.g. Ice Maker, Coffee maker). These 1/4″ plastic T's work perfectly (https://www.amazon.com/gp/product/B013ZX72ZE). The company ships more than enough feed line for most normal sized kitchens. If you need more it is easy to find 1/4″ plastic ice maker line. They sell it everywhere.

The only thing to keep in mind is this is not a small unit. It is big. It takes up a lot of space and it needs to be screwed to a wall/cabinet. It would not be a good idea to let it stand on its own. If it fell over it could cause problems with filtration. The advantage to the size, however, is it has room to hold quality filters. It does a great job cleaning the water. Our coffee tastes as good, or better, than most commercial shops.

I am very, very pleased with this purchase. I highly recommend iSpring. Their customer service is excellent as well. Email them any question you have and they respond quickly.

Review 6

Received water system with broken parts. Faucet was bent like someone had taken a set of piers to it and the water line adapter was cracked. I had two options. I could either return to amazon and get a full replacement system. Alternately, i could contact iSpring directly and get them to send the replacement parts. I figured contacting iSpring directly would be simplest. I was wrong. I tried numerous times to get them on the phone, but nobody ever answered. A few others have commented on the poor customer service. I am going to assume that those reviews are true. I am returning this and going with another brand.

Conclusion

The on-demand fast flow rate of the US31 allows it to meet the widest possible range of needs in your home. Whether it's washing fresh produce like fruit and vegetables, or providing us with some extra peace of mind about the safety of our best friends, this system can provide you entire family with delicious, clean water straight from your tap.
