How Teerless™ Cigarette Filter Works
Teerless™ is an add-on filter for smokers who don't want to change their cigarette brand. You push it onto the filter end of your cigarette, and the smoke then passes through two additional filter stages. This page explains the design, the sizes and how to use it — based on manufacturer information, without test results or percentages.
What the Built-In Filter Does — and Doesn't Do
Most cigarettes have a built-in filter made of cellulose acetate. It catches part of the particles in the smoke, but many substances — including gases such as carbon monoxide — pass through it. No filter, built-in or add-on, makes smoking safe.
Ventilation holes in "light" cigarettes lead to lower readings on smoking machines. In real use, smokers often cover these holes with their lips or fingers or inhale more deeply, so the machine values say little about what a smoker actually inhales. The German Cancer Research Center (DKFZ) has published on this.
The Teerless™ Two-Stage Design
Stage 1: The First Filter Stage
The smoke first passes through stage 1, which is designed to catch larger tar particles. In practice this means:
- The filter sits directly on the filter tip of your cigarette
- The smoke passes through the filter before it reaches your mouth
- Tar residue collects inside the filter as you smoke
- You can see the trapped residue — the used filter darkens
Stage 2: The Second, Finer Stage
The smoke then passes through a second, finer filter stage. What you should know:
- Designed to trap residue – together, the two stages are designed to trap tar residue that you can see in the used filter
- No percentages – we don't publish reduction figures for Teerless™
- Gases – the filter is not designed to remove gases such as carbon monoxide
- Not a health product – an add-on filter does not make smoking safe
Built-In Filter vs. Teerless™ Add-On
| Feature | Built-in filter | Teerless™ |
|---|---|---|
| Where it sits | Part of the cigarette | Pushed onto the filter tip |
| Filter stages | Usually a single filter | Two-stage design |
| How long it is used | One cigarette | Up to 6 cigarettes |
| Sizes | Depends on the cigarette | Regular 8 mm, Slim 6 mm (adapters for 5 mm), Slender+Slim 6.6–7.1 mm |
| Makes smoking safe? | No | No |
Taste and Draw
A common question about add-on filters is whether they change the taste. Because the smoke passes through an additional filter, the draw feels slightly firmer. Whether you notice a difference in taste is personal — we don't publish taste ratings. If you're unsure, start with a pack of 300.
Compatibility and Usage Life
Teerless™ comes in three sizes: Regular (8 mm) for standard and king-size cigarettes, Slim (6 mm) for slim cigarettes, with 100 adapters for 5 mm super-slims, and Slender+Slim (6.6–7.1 mm) for the sizes in between. Each Teerless™ filter can be used for up to 6 cigarettes; replace it when it has visibly darkened. Packs contain 300 filters; Regular is also available as a 1200 pack.
