Review: Just what I needed - Worked great just like an OEM part.
Review: Inaccuracy in product description. Fishy price. - 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.

## Questions & Answers

**Q: Can i add 3 express filters to my counter top express model, the uv, acb, and alkaline...is this possible and how many of these kits would i need?**
A: 1 kit to add 2 filters.  So, for 3 filters you need 2 kits. But, I'm not sure this fits the countertop model. Filters look the same, but I don't have them.

**Q: What fittings are needed to install just the "ION" filter under a sink for the cold water?**
A: I don't know what ion filter you wish to install. But, this set is for adding any filter of your choice to basically any under sink reverse osmosis filter assembly. So, it might work if the filter of your choice has 1/4" tubing connections. Your filter of choice must match the form factor of the other reverse osmosis filters so that the clips hold the filter in place.

### ⭐⭐⭐⭐⭐ Filter add-on
*by T***E on 29 September 2018*

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.
