The Flavor Chamber is a zirconia-glass insert that sits above the herb in the IQ3's oven, filling dead airspace when you pack less than the full 0.7g capacity. Better herb-to-heat contact means more efficient extraction and more consistent vapor from the first draw to the last. It also pairs with dosing capsules to press the load toward the heat source for tighter, more consistent sessions.

Yes — and this is the most common use case. Load a stainless steel or ceramic dosing capsule in the oven, drop the Flavor Chamber on top, and close the lid. The capsule keeps herb contained and the Flavor Chamber keeps the load pressed toward the heat. For small packs or concentrate use with extract discs, the Flavor Chamber is particularly useful for eliminating dead airspace above a half-filled chamber.

The zirconia material is durable and non-reactive — there's no set replacement schedule. Replace it when you notice flavor degradation that cleaning doesn't fix, visible cracking, or fit issues. Cleaning with ISO after every few sessions keeps it performing at its best.

No — the IQ3 Flavor Chamber is specific to the IQ3's 0.7g oven dimensions. The IQ2 and IQC use their own flavor chamber accessories sized for the 0.5g oven. Verify compatibility before ordering.
