Sean was really helpful and responsive to an inquiry. System came quickly. Water quality is great! My family is enjoying this product and we are looking to purchase an additional unit for the farm. Thanks ISpring!

This is a great filter system. My wife has multiple chemical sensitivities and this filter works very well for her. It is also very easy to replace. I usually have a set in storage and when I change them out, I buy a new set, ready to go.

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.
