Cigarette Filter Sizes Explained: 8mm, Slim, and Super Slim
Share
Cigarette filters come in several sizes, and using the wrong size for your cigarettes means the filter will not seal properly and will not work as intended. This guide explains every standard filter size — 8mm, slim, and super-slim — what cigarettes they are compatible with, and how to identify which size you need.
The Three Main Filter Sizes
| Size Category | Diameter | Cigarette Type | Available In Our Range |
|---|---|---|---|
| Regular (8mm) | ~8mm | Regular, King Size | TS Teer STOP, MINICO, Nicless, Tarmin, Teerless, BUDDYGARD |
| Slim (6–7mm) | ~6–7mm | Slim cigarettes | TS Teer STOP Slim, MINICO Slim |
| Super Slim (5mm) | ~5mm | Super-slim cigarettes | TS Teer STOP Slim (with adapters) |
8mm Filters — Standard for Regular Cigarettes
The 8mm filter is the global standard for disposable cigarette filters. Regular cigarettes — including King Size — typically have a tip diameter of approximately 7.8–8.2mm. An 8mm filter creates a snug seal around the tip, allowing the filter to capture visible tar and particulate matter effectively.
8mm is correct for you if you smoke: Standard / Regular cigarettes, King Size cigarettes, most roll-your-own cigarettes (standard width), most cigarettes sold at petrol stations and supermarkets worldwide.
Our 8mm brands: TS Teer STOP (6 pack sizes) | MINICO (4 pack sizes) | Nicless | Tarmin | Teerless
Slim Filters — For Slim Cigarettes (6–7mm)
Slim cigarettes have a narrower diameter than regular cigarettes — typically 6 to 7mm. An 8mm filter will slide on loosely and will not filter effectively on a slim cigarette. Slim filters are sized to create a proper seal on narrow cigarette formats.
Slim is correct for you if you smoke: Slim branded cigarettes (e.g., Vogue, Camel Slim, Marlboro Slim and similar), slimmer roll-your-own cigarettes (6–7mm width).
Our slim options: TS Teer STOP Slim 200 (8mm slim, includes 75 adapters) | MINICO Slim (designed for 5mm, 6mm, 7mm).
Super Slim Filters — For the Narrowest Cigarettes (5mm)
Super-slim cigarettes are the narrowest format — approximately 5mm in diameter. They are less common than slim cigarettes but popular in some markets. Super-slim cigarettes require a filter with adapters, as very few filters are manufactured specifically at 5mm.
Super Slim is correct for you if you smoke: Super-slim branded cigarettes (some luxury and boutique brands), very narrow roll-your-own cigarettes (under 5.5mm).
Our solution: TS Teer STOP Slim 200 — includes 75 adapters that allow compatibility with super-slim sizes down to approximately 5mm.
How to Identify Your Filter Size
- Read the packaging: Most cigarette brands indicate Regular, Slim, or Super Slim on the pack.
- Measure your cigarette: Use a ruler across the tip end. 8mm = regular; 6–7mm = slim; 5mm = super slim.
- Try the fit test: Slide an 8mm filter onto your cigarette. If it is snug and secure → regular. If it is loose → slim or super slim.
Size vs Effectiveness
Filter effectiveness depends on design and construction quality — not size alone. A correctly-fitted slim filter and a correctly-fitted 8mm filter are equally effective for their respective cigarette types. The critical factor is always a proper seal. A loose filter — regardless of size — will not work correctly.
For 8mm regular cigarettes, we recommend Teerless for its multi-layer smart filter construction. For slim cigarettes, TS Teer STOP Slim offers the most versatile adapter system.
Frequently Asked Questions
- What happens if I use the wrong size filter?
- A filter that is too large for your cigarette will sit loosely and will not create a proper seal — smoke will bypass the filter rather than passing through it. Always use the correct size.
- Is 8mm the same as Regular?
- Yes — 8mm refers to the diameter, and Regular or King Size cigarettes are the common format with this diameter. The terms are used interchangeably in the context of filter sizing.
- My slim cigarette is described as 6mg — is that the size?
- No — 6mg refers to the nicotine strength, not the physical diameter. Most slim cigarettes have a physical diameter of 6–7mm regardless of the nicotine strength printed on the pack.
- Can I use one filter type for multiple cigarette sizes?
- Only if you use adapters. The TS Teer STOP Slim 200 includes 75 adapters that give it compatibility across slim and super-slim sizes, making it the most versatile option for mixed users.
