WF150K

This is a great system. I am on a well for the first time and build a complete ispring system with this unit preceded by their spin down and 5 micron filter then this unit followed by a 3 system and UV. System has worked flawlessly for 5 year. Very easy to install. You just need a method for the self filter clean when it ejects some water. Whenever this unit goes out I will be buying a new one.

This is a great filter, the water quality is good. The customer service even better I had some issues with the head of the machine making a tremendous noise and Sean help me to solve it

My water was treated with so much stuff that I could smell the chlorine when I ran hot water. This filter reduced it so much I can barely taste any chlorine just one day after installation. 1 year warranty when you register, mine came with a card for a 3 year warranty free. Registering the warranty was a little confusing though, the website didn't even specify to provide a serial or model number but they will email you after and are quick to respond.

I recently replaced an old well water treatment system with an all iSpring system. These filters are awesome and extremely easy to install. The head units are simple and to the point, no unnecessary features or junk to deal with. I had a couple questions during my install and support was able to get on the phone and talk me through it without a problem. Since then I've also installed a couple of iSpring RO systems for family and they all love the difference. I've specifically worked with Sean from iSpring sales/support a couple times now and have had an awesome experience. This company has such good support and follow-up with customers, if you're looking to redo any part of your water treatment and filtration I can't think of any reason not to use iSpring. These filters are top-notch.

Great product, running fine for 3+ years. Its easy to operate and I love the clean water. Thanks Nick for all your help!

I read about a few whole house water filter systems and settled on this one. I'm glad I did, because it is now over 4 months old and no issues at all. We had nasty tasting city water and even discoloration in the water when the city would be working on it sometimes. This system has taken care of all of that perfectly. Excellent tasting water. We were buying bottled water in the drinking size, as well as big bottles every week. This unit will pay for itself in 3 years based on what water was costing us. The unit should last about 10 years, at which time I'll likely buy another one. No filters to change ever, and simple installation. I also have a lead entrance pipe, and although not the best system for that, it does reduce it. Highly recommend this unit. The I-Spring folks even followed up with me twice after the purchase, on their own, to see if I had any questions, even though it was purchased through Amazon. GEG

Worked for about 6 months. The carbon filter was not functioning. The sent a replace filter but you need a plumber to install it. This was not suppose to be replaced until the 3-5 year mark. So product was faulty and there response was hire a plumber. Bought this because there are no filters to change.

My wife used to have cuts in her fingers for no reason during winter. We did not realize it was because of the water quality. I contacted iSpring as we have an Under Sink Water Filter System for our drinking water. Nick said it could be because of the chlorine and other chemicals in the water. Nick was right. My wife did not have issues when using filtered drinking water to wash her hands. So we bought the whole home filtration system and we are glad we made this purchase. Water feels clean and tasty too. We were in a dilemma whether to buy the traditional system of this one. Finally we decided to buy this. Installation was very easy. We had a plumber come and install it for us in 2 hours. If you have some plumbing experience I am sure you can do it yourself. This unit also doesn't take too much space unlike the traditional 3 stage filtration system. 1st time setup was very easy and straight forward. I recommended iSpring to my friends for their filtration needs. Nick was super helpful and answered all the questions patiently.
