Anyway I bought one of these Ash Can Filter for my Dad because he destroys my mums Dyson on a regular basis cleaning out the log fire. Now the filter on my vacuum in the workshops gets clogged really easily so I thought I'd have a go with this and it worked superbly! The filter just tapped against a wall and was empty in seconds , I may have damp though in my workshop which causes my other filter to clog , but I noticed my normal vacuum didn’t get hot .. so for a 10’ner I thought it was a bargain .. they are £23 on amazon the robbing gets ! Just thought I’d share:)
