Arizer Air

The Air holds your herb inside a glass aroma tube rather than in the device itself, so residue collects in the bore of that tube and around its chamber end while the ceramic heater it drops into stays comparatively clean. The glass is the part that needs regular attention, and the vented heater cover at the top of the body is the part you have to protect.

1. Clear the tube while it is still warm. The stainless steel stirring tool packed with the Air is meant for lifting spent material out of both the glass stem and the heating unit. Arizer asks for at least five minutes of cooling before you handle the unit or pack it away.

2. Pull the plastic tip off the tipped stem. The Air ships with one plain 70mm aroma tube and one tipped 70mm tube. Arizer's Air manual says to separate that plastic mouthpiece from the glass first, and to give the tip no more than half an hour in alcohol. Replacement tips are sold on their own.

3. Soak the glass in isopropyl or dish soap. The manual allows either for the Air's borosilicate tubes, followed by a hot water rinse and repeated as needed. Let hot glass cool down first, since the Air's own warnings single out abrupt temperature changes as a way to crack a stem, and glass sits outside the two year warranty.

4. Leave the screens out unless you want one. Air aroma tubes have a glass screen formed into the chamber end already. Arizer recommends whole or coarsely ground material with no metal screen, saying the optional Air and Solo screens make vapour harsher, so when one does clog, drop in a fresh piece from the pack instead of cleaning it.

5. Never wet the heater. Wipe the bore with a dry swab only. Arizer's warnings for the Air are explicit: do not immerse the unit, do not pour anything into it, and do not open the body. Refit a stem only once it is fully dry.

6. Wash the silicone skin separately. Peel the clear protective skin off the body, clean it on its own, and wipe the shell before the skin goes back on.

7. Look after the battery bay. The 18650 is user swappable, and Arizer stresses matching positive and negative on the way in. Keep spares in a case away from loose metal, and avoid storing one fully charged or fully flat for more than a month.

If a freshly cleaned tube feels tight, heat the Air to its top setting for a minute or two and try again.
