Now at Alchimiaweb.com this set of 6 replacement grids for the AirVape Xs Go vaporiser, so you can replace those included with the vaporiser.
The set includes 3 grids to place in the bowl base, and 3 anti-soiling grids for the inhalation mouthpiece which prevent bits of plant matter from getting into the duct.
Thus, we can replace the original grids when they get dirty or lost, or while we clean them using isopropyl alcohol.
