Stash & Odour Control Buyer's Guide
1. Understanding Activated Carbon Filtration
Bags like the Revelry Escort use carbon filtration. Activated carbon is processed to have a massive surface area covered in microscopic pores. When air passes through, volatile organic compounds (which carry the smell of cannabis) are chemically bound and trapped inside these pores. To 'reactivate' your bag after months of use, simply place it in a tumble dryer or near a radiator for 10 minutes to release trapped moisture.
2. How Personal Smoke Filters (Sploofs) Work
Devices like the Smoke Buddy are plastic tubes containing a HEPA filter and activated carbon. When you blow smoke directly through the mouth end, the filter captures particulate matter (visible smoke) and absorbs gas molecules (odour). Air exiting the other side is completely clear and odourless. Note that this only filters what you exhale—smoke coming off a burning joint will still smell.
3. The Science of Two-Way Humidity Control
Cannabis curing and storage requires a precise relative humidity (RH) range of 58% to 62%. Under 55%, the trichomes dry out, and essential terpenes evaporate, making the herb harsh. Above 65%, there is a high risk of mold. Two-way humidity packs (like Boveda) release clean water vapour when the jar is dry and absorb excess moisture when it is too damp, maintaining a perfect environment automatically.
Frequently Asked Questions
Q. Can dogs smell through a smell-proof carbon bag?
Yes, search dogs can often detect smells even through carbon-lined bags if any trace oils are on the zipper, handle, or outside of the bag. Always wash your hands before packing stash bags to avoid scent contamination.
Q. How long does a Boveda pack last?
Boveda packs last between 2 and 4 months inside an airtight jar. When the pack loses its liquid feel and becomes rigid or crunchy, it has exhausted its water content and should be replaced.
Q. Can I wash a smell-proof bag?
Do not saturate carbon-lined bags in water, as it will clog the pores of the activated charcoal, ruining its smell-proofing capability. Spot-clean the canvas exterior with a damp cloth and warm soap only.
Q. How long does a Smoke Buddy Junior last?
The Junior model is rated for approximately 300 uses. For a moderate, daily user, it will last between 6 and 8 weeks before it becomes difficult to blow through, which indicates the filter is fully saturated.
