H2O International US4-13 Under Sink Filter System - NSA 100S and 100X Replacement

Easily installed. The water taste Great! better than the filtered water from the refrigerator.

Installed with little trouble. Extra green wire is a ground, which I attached to chassis of freezer. Works fine.

I wanted to wait to use this for a few months to make sure it worked properly and all I can say is, for our Uline BI95 14” Crescent Ice Maker, it works perfectly. I also installed an in-line ice maker filter and the ice is tasteless even from our fresh water holding tank which most people would never drink from. A new ice maker is about 1100$ so this was a great alternative. It was about a 1 hour job to replace.

Seems to work very well...but the real kicker was how easy it was to install...just un-screw the existing adaptors, and connect them to the plastic hose. Stick it in the hoiles (Literally, just push the plastic pipe in the hole) and off you go!!!!!

I think it works? Can't tell too much difference in the taste of my water, then again I don't really drink the tap water. I got the product for the fact I use the tap water to cook with. When I installed it I was not impressed with the options they give you. There is only one size fitting you can use to attach your braided sink hoses (3/8") mine are 5/8" so I needed to do some funky conversions with brass fittings I picked up at the hardware store. For the price of the item, there should be a more universal way to attach the device other than finding conversions or cutting pipes to install the right fittings. But then again, is anything easy or straight forward when you are doing a DIY job at home?

I have been using this filter for a number of years.

I can drink my tap water again! Worth the asking price.

we researched this filter and based on what we found via manufacturer and a local salesman, were satisfied that this would perform and give us the convenience of using the main kitchen faucet for 'all' our water needs.we ordered 3 units -- 1 for us, and 2 for my parents (two separate orders (same day), but shipped from the seller AND one of their backups (different sources!).the 1st unit failed after only 1 week! calcium deposits and floating layer of yech... what typically happens and signals that it's time to change our brita filter. this almost $200 system performed POORER than a $5 filter cartridge.the seller's customer service had us try one of the other filters -- it never even got off the ground -- had the deposits & floating stuff from the get go!they claim to be replacements for the NSA filters -- we used to own & sell/install NSA in the 1990's -- they may 'look' similar, but H2O International filters are sadly lacking and we would NEVER put them in the same class as NSA's (which were top notch).what are the odds of the same customer receiving two defective units from two completely different sources -- the only thing in common is the manufacturer. we do NOT recommend this product.NOTE - the seller, Appliance Cove, got a 5-star review for their service. they took care of us and issued a full refund, including sending us a pre-paid return label. they were prompt, courteous & efficient!
