I like these filters a lot, they do a good job and are super easy to replace. My wife has multiple chemical sensitivities and this filter works very well for her.
I like to keep a spare set on hand and then when I replace, simply order a set immediately for the next time.

This is the second CU-A4 system that I have put into two different fifth wheels and they are great. Most tap water taste so bad to me I can't stand to drink it, but these purification systems are great and works great in a RV. I highly recommend to everyone and especially RVers.

I have been buying springs water for drinking and even that has an inconsistent taste lately. So I decided to get a water filter system and after doing some research, I ended up with this one. Why? because it's compact, easy to install and change filters, and produce decent drinking water without waste any water.
