Berkey filter systems - care of the Berkey black filter

Post by Barefootgirl » Wed Oct 11, 2017 7:53 am

I'm somewhat inconsistent in my use of the Berkey since I travel, so sometimes I travel and it goes "dry". I've read you can put it in the fridge but not the freezer. Are you concerned about the black filter accumulating mold or unhealthy bacteria?

I rinse it on the outside and wipe it down (as well as cleaning the silver housing unit itself).

How do you care for your Berkey? thanks

DW and I clean and sanitize the Berkey filters once or twice a year and it has worked fine. We've had the same unit for 5 years.

I'd see what the manufacturer says.

FWIW, on a couple of backpacking type filters we've had over the years, the off season procedure was to suck some water with a little bleach through the filter (to kill whatever was on the dirty side of the filter) and let dry (so nothing else started growing).

You should never freeze a carbon filter element -- water expands when freezing and will destroy the ability of the filter to work as intended.

Even with mold on the surface, the filter itself should still work. Biofilms are a potential problem, but they will mainly just slow down the filter. A strong bleach solution can rectify that -- better still is a chlorine-dioxide solution using a product like Aquamira. Follow that with a good reverse flush, and your filter should be good as new.

Just re-prime the filters. I think Berkey says you can clean them with some type of brush if you need to but I've never done that.
