Non-Solid Block





Data value

dec: 0 hex: 0 bin: 0


See Data values

Air is the block present in otherwise empty space.

Cave air[Java Edition only] is the underground air found in some Generated structures, and is generated in caves.

Void air[Java Edition only] is used internally for blocks above (Y>255) and below (Y<0) the world, and in unloaded chunks.


Air cannot be kept in the inventory and can only be destroyed or created by the placement or removal of other blocks respectively.

Natural generation[edit]

Most generated structures generate air. Air is also generated in any space not occupied by another block.

Structures above ground generate normal air (with the exception of exposed badlands abandoned mineshafts and surface ponds, which generate cave air[1][2]), and underground structures generate cave air. Void air is used in place of unloaded chunks and above or below the world's buildable area.


Air, shown at left, is represented by blue cubes within structures. Red cubes represent structure void.

Air shares some properties with non-solid blocks, including allowing the player or mob to move within that space without suffocating, and also to catch their breath if they are drowning in water.

Air can be visualized with the use of structure blocks in save mode. With "Show invisible blocks" enabled, air is represented as small blue cubes.

Cave Air cave_air
Void Air void_air

Bedrock Edition:

Block ID Name Numeral ID
Air air 0


Java Edition Pre-classic
Cave game tech testAir added, but it wasn't internally a block.
Java Edition Indev
0.31 Air will now affect liquid blocks that are horizontally adjacent to it. If air is touching the fluid block, there will be a 23 chance the fluid block will disappear and make the pool recede and a 13 chance the fluid block will fill the air, making the pool spread.
Java Edition
1.7.2 13w38b Air is now internally a block[3] and can be kept in the inventory. It has a missing texture, MissingTextureInventory.png.
13w38c Air can no longer be kept in the inventory anymore.
1.10 16w20a Air can now be visualized with the use of structure blocks.
1.13 17w47a Prior to The Flattening, this block's numeral ID was 0.
18w06a Added two new variations of air: cave air and void air.
Caves can now generate cave air instead of normal air.
Void air is now internally used at Y values less than 0 or greater than 256 and in unloaded chunks.
Pocket Edition Alpha
0.1.0 Added air.
Legacy Console Edition
TU1CU11.00Patch 1Added air.
