Great Filters
Works great. I buy all my water drop filters in advance and as soon as I install a new one I order a replacement. So easy to install.

Easy to use, water tastes great.
We've been using the Waterdrop RO system for over 5 years now with no issues (with the main unit). Filter changes are super easy and quick. Water tastes great. A little pricey up front, but with 1:1 water use, you'll save money on less waste water. Waterdrop customer service was quick to send us a replacement faucet (LED filter ring failed). Very pleased and expect this unit to last 5 more years.

simple installation, kind of expensive but it lasts for 6 months so i think it's worth it. Great tasting water for sure.

Remove Lead
One of my better investments for my health while this was being used my city East Dundee Illinoise informed me that the Lead content had gone up in the water. No worries I use the water drop reverse osmosis which takes care of over 99% of lead.
