Across 4 shops. More compact than Solo 2, cheaper than Air Max.

The Air 2's signature feature is its glass vapor path. Arizer's glass stems serve as both mouthpiece and herb chamber. Glass is flavor-neutral -- vapor arrives pure and unaltered. No plastic, no silicone in the airway.

Stems come in different lengths. Longer ones cool vapor more, shorter ones are more compact for travel. Replacement glass is cheap and easy to find.

While most portables have sealed batteries, the Air 2 uses a removable 18650 battery at 3200 mAh. Battery dead? Swap it out and keep going immediately.

A spare battery costs just a few euros and extends session time indefinitely. On trips or longer evenings, that is a real advantage over sealed-battery devices. The battery can also be replaced after a few years when capacity drops.

Arizer offers dosing capsules that fit inside the glass stems. They make loading easier on the go and keep stems cleaner. The chamber is slightly smaller with a capsule though.

Other useful accessories: the long glass Aroma Tube, a travel case, and various screen sizes. Arizer has a wide ecosystem that is also compatible with the Solo 2.

Arizer built the Air 2 around interchangeable glass stems that double as the herb chamber and the mouthpiece. Because the vapor path is almost entirely glass, there is very little flavor interference from plastics or metal. You taste the terpene profile of your material more clearly than in vapes with silicone or rubber air paths. The stems pop out for quick cleaning in isopropyl alcohol and cost only a few euros to replace if one breaks. Carrying a pre-packed stem in a tube means reloading on the go takes seconds instead of fumbling with a grinder outdoors.
