Hookah HMDs in aluminium or stainless steel, with or without a lid
An HMD, short for heat management device, holds the charcoal in its own housing above the bowl, so you can skip perforated foil. The aluminium range covers Kaloud Lotus 1+, Darkside D-Heater, AO HMD Sandblasted, Huka HMD and INVI Scalar; stainless steel brings ONMO, Mira HMD V2A, Babuschka and AO HMD 912. Chimney tops with screen and tube sit in their own chimneys subcategory.

Telling the heat paths apart
A chimney attachment works with a screen and chimney tube. An HMD holds the charcoal in the attachment; some models also have a lid. Electric heads generate the heat themselves and are a device type of their own.
Seat and material
Compare head and attachment by diameter and rim. Aluminium absorbs heat faster than stainless steel; wall thickness and design also influence behaviour. A lid is only part of the regulation if the model you choose has one.
Detailed differences between foil and chimney can be found in the HMD guide. This category is for choosing the attachment.
Choosing an HMD: Kaloud Lotus and ONMO
Kaloud is a brand, and Lotus names its HMD range. ONMO HMDs are separate models with their own dimensions. Compare the supporting surface with the bowl rim rather than assuming compatibility from a brand name.
Chimney top or complete bowl set?
A chimney top is an individual component. A chimney bowl set combines the bowl and top; check its parts list under bowl sets with chimney tops. To assemble a combination yourself, start with the hookah bowl selection.
Frequently asked questions about HMDs and chimneys
What is an HMD?
HMD stands for heat management device: a top for your bowl that holds the charcoal instead of letting it burn on foil.
What is a smokebox?
Usually an HMD with a lid. With the lid on, heat builds up; with it off, the device runs cooler. Whether a model comes with a lid is stated on the item.
Aluminium or stainless steel HMD?
Aluminium heats up quickly and responds fast, while stainless steel takes longer to get going. Kaloud Lotus 1+ and Darkside D-Heater are aluminium, ONMO and Babuschka are stainless steel, and the stainless models have their own subcategory.
HMD or chimney top: what is the difference?
An HMD holds the charcoal inside the device, while a chimney top keeps it on a screen under a tube that shields the embers from wind. Chimney tops from AO, Diamond Hookah and Huka are listed under chimneys.
