It contains two Air Filters and serves as a replacement for a possibly dirty Air Filter in the VOLCANO.
SPECIFICATIONS
Use this replacement Air Filter Set for your Volcano when the old ones have outlived their usefulness. Dirty, clogged air filters will degrade the performance of your Volcano vaporizer and so we recommend that you replace them after a long period of use. This length of time will vary for different people as some use theirs more often than others.
The Air Filter Set contains 2 replacement filters.
