Purize Activated Charcoal Filters (Regular) are 9mm coconut-charcoal joint filters that trap tar, ash and combustion nasties before they hit your lungs. Each pack holds 100 filters with ceramic caps at both ends, a resealable pouch to keep them fresh, and a construction that's become the benchmark for every other charcoal filter on the market. If you've been rolling with cardboard roaches and wondering why your throat feels like sandpaper by the third joint, this is the upgrade.
Why coconut charcoal actually matters for your joint
Purize filters work because of what's inside them: activated charcoal made from coconut shells, packed between two ceramic end caps. When smoke passes through the carbon, the porous surface adsorbs tar, larger particulates and some of the harsher compounds produced by combustion — the stuff responsible for that scratchy, ash-flavoured hit at the end of a joint.
The difference is immediate. Your weed tastes like weed instead of smoke. Terpenes come through cleaner. The ceramic caps stop carbon dust from ending up in your mouth (the single biggest complaint about cheaper charcoal filters), and they also stop your filter from collapsing when the joint gets wet at the tip. Zippers, cardboard roaches and glass tips all have their place, but none of them strip harshness the way coconut charcoal does.
One honest limitation: a charcoal filter reduces tar and harshness, but it is not a health device. You're still smoking. Think of it as the difference between drinking tap water and filtered water — cleaner, better tasting, but not medicine.
Regular 9mm vs Slim and Xtra Slim — which Purize do you need?
Regular is the 9mm size, designed for classic-width joints rolled with standard or king-size papers. If you roll fat cones, dutch tulips, or anything where the mouthpiece sits naturally around 8–10mm, Regular is the one.
| Filter | Diameter | Best for |
|---|---|---|
| Purize Xtra Slim | 5.9mm | Thin pre-roll style joints, joint rollers set to slim |
| Purize Slim | 6mm | King-size slim papers, everyday spliffs |
| Purize Regular | 9mm | Classic joints, cones, fatter rolls |
If you're rolling with Raw Classic, OCB Premium or any standard-width paper and you like a mouthpiece you can actually get your lips around, Regular is the default pick. Go Slim only if you specifically roll skinny.

Why you need this if you roll regularly
Rolled a joint with a cardboard roach lately? You already know the problem: by the time you're two-thirds through, the cardboard is soggy, the smoke is hot, and the last third tastes like a bonfire. Cardboard roaches were never designed to filter anything — they're just there to stop weed ending up in your mouth.
Purize changes the mechanics of the joint. The 9mm carbon core cools smoke as it passes through, adsorbs a large portion of the tar, and the ceramic caps keep the airflow consistent from first puff to roach. The difference is most obvious on the final third of a joint — the part that usually gets thrown away because it tastes terrible. With Purize, you actually smoke it.
We sell a lot of rolling accessories at the shop. Out of all the filter options on the shelf — glass tips, cardboard, cellulose, reusable wood — Purize is the one customers come back for by name. It's the filter that made "active filter" a standard category in European smokeshops.
How to use Purize Regular filters
- Pop a filter out of the resealable pouch. Don't leave the pouch open — humidity degrades activated charcoal over time.
- Place the filter at the mouthpiece end of your rolling paper, ceramic cap facing out.
- Roll your joint as normal around the filter. The 9mm diameter works with standard and king-size papers without needing to pinch or adjust.
- Light and smoke. You'll notice the draw is slightly tighter than with a cardboard roach — this is the carbon doing its job.
- Dispose of the used filter in regular waste when finished. The carbon has trapped the unwanted substances; don't reuse it.
Frequently Asked Questions
Can I reuse Purize activated charcoal filters?
No. Once used, the activated charcoal has adsorbed tar and particulates and has no capacity left. Reusing a spent filter gives you all the harshness with none of the filtering. One filter per joint.
Do Purize filters remove THC or CBD?
Activated charcoal primarily binds to larger particulates and tar rather than cannabinoid molecules, and Purize's own testing shows cannabinoid loss is minimal. You'll notice a cleaner taste, not a weaker joint.
What makes Purize filters different from other charcoal filters?
Two things: coconut-based activated charcoal (more porous than cheaper wood-charcoal alternatives) and ceramic end caps on both sides. The ceramic caps stop carbon dust from reaching your mouth — the main complaint with budget charcoal filters.
Are Purize filters eco-friendly?
The activated charcoal is made from coconut shells, a renewable by-product of the coconut industry. The filters themselves are disposable and should go in regular waste. The packaging is a resealable pouch rather than individual wrappers, which cuts plastic compared to some competitors.
Will Purize filters fit in a joint roller?
Yes, Regular 9mm filters fit standard joint rollers designed for king-size or classic papers (110mm rollers work well). If you use a slim roller, you'd want the Purize Slim (6mm) instead.
Do I still need a tip or roach with a Purize filter?
No — the Purize filter replaces the cardboard roach entirely. The ceramic cap acts as the mouthpiece, so you roll the paper directly around the filter with no extra tip needed.
