EXPRESS WATER PRTUPKIT14 Filter Upgrade Kit for Reverse Osmosis, Universal, White

Worked great just like an OEM part.

I love my Express Water system, but unfortunately this upgrade kit is mostly a huge money grab in my opinion. It cost me $55, but the price written on the package slip when I received it was $19.84. Something is fishy, because even if I account for conversion between USD and CAD, things still don't add up. Regardless, it is quite expensive for what you get, but necessary if you want to upgrade your system. Also, the 4 filter clips description is not accurate. In the product description, you can see that there are 2 clips of 1.5"x2.2" type, and 2 clips of 2.2"x2.2" type. What I received was this: 2 clips of 1.5"x1.5" type and 2 clips of 1.5"x2.2" type. I could have used the 2.2"x2.2" clips much better, but fortunately I could use the 1.5"x2.2" instead. The 1.5"x1.5" clips are useless.

If you want to add another filter stage or or an alkalinity booster, this is the kit. Fits most osmosis filter systems if the top filter is accessible. Other fittings and tubing make it an easy process that can up repeated every 6 months or year when replacement becomes necessary. Takes up minimal space under the sink by going vertically. Great product.

This gets the job done but they should give you more parts for the price your paying. 5' of tubing is just barely enough tubing, and I'm always losing those blue clips. Especially when you can get 100' of the same tubing from other sellers a lot cheaper. Disappointing that they are so cheap with what they include, it would only cost them a tiny bit more to include some more and would make the install a lot less stressful. Another pair of large filter clips would be nice too.

Great for adding additional stages to Water Express RO system. I did use 4 1/4 elbows to route easier.
