Actually Sawtroll the Husky filtration system does not seem to keep the ultra fines at bay such as dead Redgum dust but does work very very well on ejecting larger particles away from the filter.
In fact the Husky system is far worse than the Dolmar HD system on the 7900's etc in this regard.
Which Husky models are you referring to?
The saws discussed here are 50cc ones, not the ol' 288 and 3120 (they don't have that system).
