Personal Egress Air Packs, or PEAPs, were devices on board a Space Shuttle which provided crew members with approximately six minutes of breathable air in the case of a mishap while the vehicle was still located on the ground.

* Supply of breathable oxygen and elimination of carbon dioxide ; these gases are exchanged with the spacecraft or a portable life support system ( PLSS )

By using a chemical reaction rather than a connection to an oxygen tank, these devices supply breathing oxygen for long enough for the airliner to descend to thicker, more breathable air.

Manufacturers report that insulated siding is permeable or “ breathable ,” allowing water vapor to escape, which can protect against rot, mold and mildew, and help maintain healthy indoor air quality.

What characterizes a scuba set is its full independence from the surface as a breathing device, by transporting breathable air or other kind of breathing gas.

* Maximum Vapor Permeability, the extent to which " breathable " fabric will let moisture vapor pass through ( usually measured in g / m² / 24h )

There are also breathable variations, which allow water vapour to pass through the felt ; when used in conjunction with proper ventilation, they help minimize condensation in loft spaces.

This problem has been alleviated somewhat in recent years with the advent of waterproof / breathable fabrics, such as Gore-Tex, which allow some humidity to pass through the fabric while blocking most external water.
