Awesome unit. I love it!
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.

Great Product and the representative SEAN – is Excellent !
I recently purchased the 3-layer water filter for under the sink, and I’m really impressed with its performance! The installation was straightforward, and the water quality has improved significantly since I started using it. The filter works well, providing clean, fresh-tasting water for my family.I also want to give a special thanks to Sean, the customer service representative, who was incredibly helpful when I had a few questions about the product. He took the time to answer all my concerns and made sure I was fully informed. Excellent service!Overall, I highly recommend this water filter to anyone looking to improve their water quality. It’s a reliable product with great customer support from Sean!

Outstanding WE love this
We bought this in August and it had a problem with the faucet and so we got in touch with the company instead of returning it. Laurence helped us and had the problem fixed within a few days.The unit is outstanding, wish we had gone for this years ago instead of the filter on the end of the faucet (Not sure if I can write the name). It took about 15 mins to install, it is really fast delivery of water compared to the old one, tastes great and has not shown any leakage.Please note, if you have a pre-drilled hole in your sink for a soap dispenser it will fit in there, but only just. (The hole is almost too big). We are happy as clams with this unit.

Tasteless H2O
Love this 3 way water filter. I refill water bottles, use this filter for my ‘water in the door refrigerator’ and also use it to make my coffee. It takes all of the nasty taste out of the city water. Easy to install.

We hooked this up and use it daily! Saves on plastic bottles for us. We have a business and our employees use it and like it!

Push to connect. Don’t overtighten.
I am a farmer but also a trained HVAC guy with a lot of plumbing experience. I’ve read instructions and turned a few wrenches 1,000’s of times in my life but not a professional.This system is VERY easy to install for someone who is handy. Directions are clear. The water is great. High chlorine in our neck of the woods and no chlorine taste post filter.There are videos, which I didn’t watch, explaining how a push to connect (ptc) fitting works. If you’re not familiar please watch them. It is simple but also easy to mess up.EVERY fitting that is not connected, including the filter canisters, are sealed with o-rings. Tighten those just to where there is a little resistance and then go 3/4 to 1 more turn. DO NOT tighten anything with a rubber seal or o-ring till it’s as tight as possible. You will ruin it and cause a leak.Do these things and you’ll be happy with it.

The unit is well built & it feels very sturdy. Unfortunately, it was missing the front & back washers for the faucet. I emailed customer service about it. The following day, Nick replied & said he would use express courier to send me the missing parts. I also asked Nick if it was possible to send an adapter that would allow me to connect to an existing valve instead of using the valve supplied by iSpring. To my amazement, Nick made the promise. The parts arrived a few days later. Installation was very easy. There was no leakage at all. You have to make sure not to over tighten the connections. I decided to purchase tubing from my local hardware store that had 0.17″ inside diameter instead of using the one supplied by iSpring that had a smaller 0.142″ inside diameter. I believe that made the flow rate better. There is no issue with the taste of the water, this coming from someone who switches from a Reverse Osmosis system. The only thing I don’t like is there is always a droplet of water hanging at the end of the faucet after every usage. However, it’s only a minor issue. I would like to thank Nick for his excellent work & all his help!
