Reducing Tar While Smoking: 5 Things to Know

📅 January 2026 · 5 min read

Many smokers look for ways to inhale less tar. Some steps make sense, others help less than they seem. Here are five things to know. We don't give percentages: for most of these points there are no reliable figures for the individual smoker, and for TS Teer STOP we have no measurement data.

1. Consider an Add-On Filter — With Realistic Expectations

An add-on filter such as TS Teer STOP is pushed onto the cigarette. Its two-stage design is meant to trap tar residue, which you can see in the used filter. We don't state how much less tar you inhale, because we have no measurement data that would support a figure. A filter does not make smoking safe.

Keep in mind: no measured reduction figure for TS Teer STOP · each filter is meant for up to 6 cigarettes

2. Smoke Less of Each Cigarette

Every puff you don't take is smoke you don't inhale. Putting a cigarette out earlier reduces the number of puffs — as long as you don't make up for it by smoking more cigarettes or by puffing harder.

Keep in mind: only helps if you don't smoke more cigarettes instead

3. Don't Make Up for It With Deeper Puffs

Smokers often compensate: when a cigarette or a filter delivers less smoke per puff, they unconsciously puff harder, take more puffs or inhale more deeply. This can cancel out the effect. Pay attention to how you smoke, especially when you start using a filter.

Keep in mind: compensation can cancel out the effect of a filter

4. Don't Rely on "Lower-Tar" Cigarettes

Tar values measured by smoking machines do not show what a smoker actually inhales. Smokers of "lighter" cigarettes tend to compensate, and such cigarettes have not turned out to be less harmful. Switching brands is therefore not a reliable way to inhale less tar.

Keep in mind: machine-measured tar values don't reflect what you inhale

5. Replace Filters Regularly

If you use an add-on filter, follow the manufacturer's guidance: TS Teer STOP filters are meant for up to 6 cigarettes each. Replace them afterwards — a used filter is a consumable, not something to stretch.

Keep in mind: up to 6 cigarettes per TS Teer STOP filter

Putting It Together

The surest way to inhale less tar is to smoke fewer cigarettes — and the most effective step of all is to quit. Smoking causes serious harm with or without a filter. If you want support, your local quitline can help you plan a quit attempt.
