Hi - had this a few months and at first was gutted as I thought you had to clean every time (which I think it says to). Ignored that as worse than emptying the ash before, and am happily emptying ever 5-6 small fires.
Thanks a lot for highlighting the alternatives. Based on past experience with Valiant (with a stove fan in this case), if not too far off the price of alternatives, I would recommend going for it as it was a completely different class to the two other models I had (but time will tell here).
Thanks for highlighting pollution minimisation OP. Props to you.

Surely the filter on this is going to need cleaning almost every time you use it?
