This is a Smoke Filter. Excelent for cigarets or weed. Absorb all the heavy componest of the smoke, releasing only CO2. Remove odor and protect others from the toxic smokes of your cigarette.

In order to makes the actual filter, you will need:
-activated carbon (can be bought in a petshop, is usually used to filter water from fish tanks)
-cotton (optional)

You'll have to put it in the same way shown in the images.

Change the filter once in a while.

PD: The aerospike nozzle at the end is there just for aestethic purposes
