This borosilicate glass bubbler fits onto the mouthpiece of the Wolkenkraft ÄRiS Ultra and adds water filtration to the vapour path. You fill it with a little water, and the vapour bubbles through on its way to your lips.

Water cooling makes a clear difference to the session. Vapour arrives cooler and smoother, so longer draws stay comfortable. Flavour also comes through more clearly. If the mouthpiece feels warm towards the end of a four-minute session, the bubbler is the fix.

Two things are worth knowing in use. First, use only a small amount of water - overfilling pushes water towards your lips. Second, as you inhale, tilt the bubbler slightly towards you and lower your head. Borosilicate glass handles the heat of repeated sessions and rinses clean under warm water. The bubbler adds a fair bit of height to the vaporizer, so it is built for home use. For pocket carry, the standard mouthpiece remains the better choice.

Intended for use with: Wolkenkraft ÄRiS Ultra.
