Filter tips (also called crutches) are essential for joint rolling, providing structure, preventing cannabis from entering your mouth, and giving you something to hold. This guide teaches multiple folding techniques and how to create perfect filters every time.
Quick Answer
To make a basic filter: Cut cardboard to 2"×0.5", fold one end back-and-forth 3-4 times (accordion), roll remaining paper around accordion. The accordion prevents collapse. Alternative techniques include spiral method, M-shape, and W-shape - all work well with slight airflow differences.
Why Use Filters?
Benefits:
- Provides structure and shape
- Prevents cannabis/ash in mouth
- Cooler smoke (extra distance)
- Something to hold without burning fingers
- Can smoke joint completely
- Keeps joint from getting soggy at mouth end
Without filter:
- Joint can collapse
- Roach waste (can't smoke last bit)
- Harsh final hits
- Difficult to hold when small

Materials
Best:
- Specialized filter tip paper (sold in booklets, perfect thickness)
- Business cards (uncoated, white)
- Index cards (cut to size)
Acceptable:
- Thin cardboard from packaging
- Playing cards (if desperate)
Avoid:
- Glossy or coated paper (releases chemicals when heated)
- Regular paper (too thin, collapses)
- Magazine pages (ink and coating)
Technique #1: Accordion/Fan Fold (Most Common)
Why It Works:
The accordion prevents the filter from collapsing while providing good airflow through the folds.
Step-by-Step:
- Cut material to about 2 inches long, 1/2 inch wide
- Accordion fold one end: fold forward, then back, then forward again (3-4 folds)
- Roll the rest of the paper around the accordion
- Adjust tightness to match your joint diameter
- Should be cylinder shape with accordion visible at center
Diameter: About pencil eraser size for standard joints
Practice tip: Make 10 in a row to develop consistency
Technique #2: Spiral Method
Why Different:
Creates more concentrated airflow through spiral center. Some prefer the draw.
How To:
- Start at one end of filter material
- Roll VERY tightly into spiral (like cinnamon roll)
- Continue rolling the outer paper around spiral
- Should create dense spiral at center with rolled paper outside
Best for: People who like tighter draw and more resistance
Technique #3: M-Shape/W-Shape
Why Different:
Creates structural channels along entire filter length. Very stable, won't collapse.
How To:
- Fold entire filter material into M or W shape (zigzag along full length)
- Can leave as zigzag or roll around itself
- Creates multiple airflow channels
Best for: Structural integrity, less about airflow
Technique #4: Simple Roll (Easiest)
For Absolute Beginners:
- Just roll the filter material into tight cylinder
- No accordion or folds
- Works but can collapse while smoking
Pros: Fastest, easiest Cons: Can compress, less stable
Size Considerations
Standard Size:
- Length: 2 inches of material
- Final diameter: 6-8mm (pencil eraser)
- For 1¼ papers: Perfect fit
Larger Filters:
- For king size papers: 8-10mm diameter
- For blunts: 10-12mm
- Use more material (2.5-3 inches)
Smaller Filters:
- For slim/European papers: 5-6mm
- Less material needed (1.5 inches)
Rule: Filter should be slightly smaller than joint diameter for snug fit
Common Filter Problems
Problem: Filter Falls Out
Cause: Too small, not integrated into roll
Fix: Make filter larger diameter, ensure it's rolled INTO joint not just placed at end
Problem: Filter Collapses While Smoking
Cause: Using simple roll instead of accordion, or material too thin
Fix: Use accordion method, use thicker material
Problem: Too Tight to Draw
Cause: Rolled too densely, accordion too compressed
Fix: Roll slightly looser, use fewer accordion folds (2-3 instead of 4-5)
Problem: Uneven/Crooked
Cause: Inconsistent rolling pressure
Fix: Practice rolling evenly, rotate as you roll
Pre-Made vs Hand-Made Filters
Pre-Made Filter Tips (Booklets):
- Consistent size
- Perforated for easy tearing
- Designed specifically for purpose
- Various fun designs
- $2-5 per booklet (50-100 filters)
Hand-Made (Business Cards, etc.):
- Free
- Always available
- Can customize size
- Requires cutting
Most people use both: Pre-made when available, improvise when needed
Advanced: Glass and Metal Filters
Glass Tips:
- Reusable, cleanable
- Very cool smoke
- Won't get soggy
- More expensive ($5-20)
- Can break
Metal Filters:
- Ultra-durable
- Cleanable
- Multiple designs
- Cool smoke
- Can get very hot
Cardboard still most popular due to disposability and perfect function.
