Review on Berkey COMINHKPR69752 Black Primer: An Essential Tool for Heavy Duty Paint and Surface Preparation by Joe Meyer

You just have to have this thing! I'm scared of traveling and when I'm in hotels I never know if the sink is big enough to fill my black filter. To fill the black filter you have to submerge it in water, FYI. To keep this in mind when using this tool, I place a black filter in the bottom of my barley travel container and fill it with water. Then you just press. It takes about five minutes, if that. Also, you refill without water and it helps dry out the travel black filter. I love him. I can recommend him unreservedly. I wish I had known that earlier.
