i inverted the valves on mine... (the valves would originally open up when you were breathing, because that's where the airfilters sat, and woudl close when you exhaled...) so my smoke doesn't sit there, everytime you breathe you get new smoke... it does burn up alot of weed... but it's not like you can sit in it for long... after awhile you start to get dizzy from the lack of oxygen...
