CUW4 Tankless 0.01μm Compact Under Sink Ultrafiltration Water Filter System | PureDrop

This is our 2nd unit. Very inexpensive compared to other units so we were skeptical but we are completely satisfied. Only comment is on the filter monitor which on the 1st one never worked. We now have the install date posted on the machine so we know when to replace the filters.

Have Been Using a CUW4 for the past 3 Years. No Problems. Having a Hard time finding Replacement filters. Went to the Puredrop web site and had no problem obtaining the filters that I needed.

This is the second all in one unit we have purchased. The ease of installation is so simple a child could almost do it. We live in an area where the water is full of minerals and is very hard, the taste isn't the best either. With this filter, the taste has improved 10 fold. We've also noticed a lot less calcium buildup on pots and pans, glasses and other items.
We've only had one minor issue, the display has quit working on the first one we purchased, which has yet to be addressed by the warranty department.

This unit is pretty bulky under my sink. The filtered water is great, it flows easily until it’s time to change the filter. Filters are very expensive compared to the unit. I encourage you to shop both the filter and replacement cartridges.

Before I bought CUW4 model I spoke with Nick who described the system. It was a pleasure to speak with him because he gave me an expert description of the system. Also he provided excellent customer service. Thank you Nick!
