Thread: After Servicable Life Alternative Uses for Stefani Ceramic Water Filters

I used to just scrape the brown stuff off the outside with a knife and use it for another 6-12 0r whatever months. Worked fine. I don't think they could be called ceramic more like dolomite or chalk rock.

Exactly as Philip says...............

Everyone I know who uses them does just that.

Lionel, I sent your query to my sister, who sent this reply:

I've wondered the same thing. We broke some up and put (just the ceramic bits, not plastic) the pieces behind the retaining wall before we topped up the soil once. But that was just a one off. I have read that they are good for water absorption and if you break them up and spread them out and then cover with compost, they're good but I don't know if that's true or not. I'm thinking of trying it with our current one.

Hello Saitch,

Thank you for your reply and for passing the query onto your sister. In the interim I fell back to my horticultural training - that included irrigation and drainage. I wonder how the filter cartridges would go in a wicking type of arrangement covered up in either a large plant pot or positioned in a garden bed within the root zone. Where the irrigation pipe is attached to the filter cartridge and connected up to the water source. Some drip irrigation arrangements feature a button emitters that can be fitted to the main irrigation line. The button emitters have multiple outlets that thinner delivery lines are connected to. One such thin 'spaghetti' line could be connected to a single used filter cartridge. Yep, total overkill. At least it is a possible use for the old filter cartridge and they are not just thrown away.

Kind regards
Lionel

My first one (~25 yrs ago) came with that in the manual. Just scrape the outer layer off with the back of a knife and keep using it until either there is none left or the water tastes funny. I think I used 2 in about 6 years.
