I really don't know about the type of stove; things I've read about this refer to the type of fuel, and in this case specifically problems with burning wet wood rather than seasoned wood. (It's possible that some stoves or chimneys that vent them have some sort of particulate removal systems, but if they exist, they must be an absolute nightmare to unclog/clean etc. Having said that, I did find this site - https://woodstovefilter.co.uk/ https://woodstovefilter.co.uk/ - which seems to offer a solution ... but the product doesn't exist yet; it says "Expected to be ready for commercial sale early 2022". EDIT TO ADD: Actually, there seem to be a few companies selling "strap-on" systems to fit to chimneys that work on electrostatic removal of particles, such as Enervex [2], but again that's not to do with a stove type.) The Guardian article points out that wet wood sales are to be banned from May this year: "The government is not planning a ban on wood burners but a ban on the retail sale of wet wood will come into force on 1 May, as will a ban on bags of house coal, the first such restrictions since the clean air acts of the 1950s. Wet wood has not been seasoned and produces higher levels of pollution." The article also links to the UK Govt announcement [1] from last year, which as far as I can see has nothing to say about stove type, only fuel.
