I'm one year in on my first set of WaterDrop filters (chlorine + flouride), and I've loved them. Great taste, and what I like the most is that the carbon filters never clogged. I never needed to clean them. Just ordered another set. I recommend!

High quality, efficient filters. Be sure to purchase the metals filters too. They're worth every penny filtering chlorine and fluoride.

Better buy than the Berkey brand

Exactly what I expected & as described

I orderd the full Water Drop filtration container unit a year ago. I use it OFTEN and the water filters came apart from their bases..... I figured that it had been too long so I ordered these replacement filters. ( I should have read through the comments here first) The instructions that came in the package leave out a few steps so I found the Waterdrop YouTube Channel and watched how to assemble a new unit. The pictures on this listing and the instructions in the official WaterDrop Video differ. Does the black gasket go over the hole in the upper chamber before putting the water filter through, or over the hole in the bottom chamber before screwing the PF2 filter on? The YouTube video says it goes on the bottom before the PF2 filter is installed, but the pictures here in this listing show it before the water filter is installed, which is how I have done it for the past year....... ????? I need to know. the correct way
