A joint filter – also called a tip – sits at the mouthpiece end of the joint. It stabilizes the mouthpiece, holds back crumbs and ash, and makes drawing more pleasant. A small part with a noticeable effect.
What is the filter for?
Without a tip, the joint quickly draws material and ash into the mouth and compresses when drawn. The filter provides structure, keeps the end open, and ensures a smooth draw. In addition, the joint can be smoked to the end without burning your fingers.
What types of joint filters are there?
- Cardboard tips – the classics, self-rolled from thin cardboard.
- Pre-made filters – pre-formed tips for direct insertion.
- Activated carbon filters – also filter out pollutants and cool the smoke.
- Glass filters – reusable, tasteless, and durable.
Cardboard, activated carbon, or glass filters?
A cardboard tip serves its purpose and is inexpensive. An activated carbon filter makes the draw noticeably smoother and filters out more. A glass filter is the sustainable long-term solution: buy once, use again and again, no inherent taste.
Frequently Asked Questions
Does a cardboard tip filter anything at all?
Chemically hardly – it mainly provides stability and holds back crumbs. For real filtration, you need activated carbon.
Can I use a glass filter multiple times?
Yes, that's exactly its advantage. Briefly clean, reinsert, done.
How do I roll a cardboard tip?
Usually with a small accordion fold at the beginning, then roll it tightly. Practice makes perfect.
