I give a blow into my unit after every bowl while everything is still hot. I tilt the unit and don't blow directly into it, and a lot of the particulates that chill around the screen just fly right out. You'll eventually get a rim of herb around the bottom, but it's nothing bad. Also I always make sure I heat tamp or light tamp to avoid little bits from falling out if possible...there's always some bits that'll fall outta the bowl tho, so just blow into ur milaana for a bit. (if you don't know this...careful about getting herb in your eye)

I decided to make a video that was strictly me cloud chasing for the sake of "making it hard to see me" as
@DDave says. Hope you guys enjoy this with at least a fraction of the enjoyment I had making it. In the end, it wasn't much herb. Probably .15-.2, and I didn't vape it all the way through.
I forgot to vape my micro bubbler thing bowl too...Will get vid of that soon...once these effects wear off a bit haha.
