All UF or sub-micron filters produce mineral water. Any (assuming good quality of course) sub-micron filter will remove 99.99% of bacteria. Therefore there must be no need for UV. And yes, good sub-micron (UF, electro-adhesion etc) filters with quality carbon block would handle that organic compound described in the article. What wouldn't tackle it is something like a filter presented few pages up, simple sediment (only) by 3M and GE and the backwash one.

In fact, UV very often used in RO systems, but for a totally different reason, because water is sitting in the tank where it is exposed to bacteria.
In case of Amway, there are 2 options: either UV is totally redundant and is there to make filter more expensive, or the filter itself is not very effective and therefore there is UV version that's more effective.

No offense, but water filter from MLM company is not such a good idea. Again, this is just my opinion. I'm not saying it's bad, maybe it's ok. I'm just suggesting that there are better systems with lower maintenance cost and lower initial investments.
