Do the moisture sponges have to be damp when installed into the BioPak?
It is stated by the user manual to open the lid of the BioPak and wet the sponges prior to use. This will provide the best inhalation gas cooling possible by the BioPak as the wet sponges provide a seal around the lid baffles that will insure that air flow is directed around the coolant canisters. Failure to wet the sponges prior to use may result in warmer than usual air temperatures at the start of BioPak use.
