My wife and I invested in a

My wife and I invested in a Waterdrop G3P800 after noticing the health benefits of drinking distilled water.. We like how this will practically pay for itself, reduce plastic waste, and provide clean, lead free water for drinking and cooking via a dedicated spigot. Personally, I only notice a slight difference in taste compared to distilled water.

Great products. I bought this

Great products. I bought this tankless RO unit to replace a tank with permeate pump system. I was tired of the filter changes on the tank system. I'm looking forward to the filter change on the tankless system.

This system is so quiet. Our

This system is so quiet. Our last one was really noisy. Before we added the remineralization filter, the flavor of the water wasn't very good, but we live in an area where the water is extremely hard. We are very happy with this system.
