Whether you're just getting into roll-your-own or you've been at it for years, the filter you choose makes a bigger difference than most people realise. Activated charcoal carbon filters come in four distinct sizes, and each is built for a different kind of smoker. Let's break them all down.
What Makes Carbon Filters Different?
Before we get into sizes, here's the quick version: Carbon filters use activated charcoal inside the filter tip. This helps reduce harshness and tar, giving you a noticeably smoother draw compared to plain cellulose or paper tips. The activated charcoal acts as a natural filtration layer so you get full flavour without the rough edges.
Now, on to the sizes.
🔵 The 7mm Range
The 7mm Range are the widest in the carbon filter range. With its signature designs, this are built for smokers who want maximum draw and full, uncompromised flavour. The slightly larger diameter means a more open airflow, making it the go-to for those who prefer a relaxed, effortless pull.
- Size: 7mm
- Best for: Full flavour lovers, those who find slim filters too restrictive
⚪ The Classic XL 6mm Extra Long
The XL Range is in a category of its own. It's the longest filter in the range giving you an extended charcoal filtration zone that most standard filters simply can't match. The reggae-inspired red, yellow, and green branding isn't just for looks; this one has a personality as big as its size.
- Size: 6mm diameter
- Best for: Long sessions, heavy smokers, anyone wanting maximum filtration
🟠 The 6mm Range
The 6mm range keeps things quiet from its understated cre packaging to its no-fuss, everyday 6mm size. Don't let the subtle design fool you though; it's still a full activated charcoal filter delivering that signature smooth hit. This one's are perfect if you just want a reliable, everyday filter without any fuss.
- Size: 6mm
- Best for: Everyday use, those who want a classic slim experience
🟢 The Super Slim 5mm
The 5mm Range is designed for smokers who prefer the tightest, most refined draw possible. Despite its compact size, it still delivers full flavour the activated charcoal does the hard work without sacrificing taste. The vibrant red-yellow-green colourway makes it instantly recognisable, and the compact pack slips easily into any pocket.
- Size: 5mm
