Cheap Britta style filters. Anygood?
In a local Home Extra shop is see they are selling Britta style water filters for £2.99 including 1 free carbon filter (the spec is the same as filters that cost 10 times more). Are these style of filter of any use? I've been told ill need to filter the vodka twice to take the impurities out. I'm using a SS turbo air still and the wash is made with alcotec vodkastar yeast. I'll dilute the product to 40% using filtered water too.
