Cigarette Filter FAQ: 25 Most Asked Questions Answered

Everything you ever wanted to know about cigarette filter attachments — answered in one place. From how they work to which size fits your cigarettes, we cover all 25 most common questions.

The Basics

1. What is a cigarette filter attachment?

A cigarette filter attachment is an add-on that you push onto the filter end of a cigarette, so the smoke passes through it before it reaches your mouth — in addition to the built-in cellulose acetate filter. TS Teer STOP has a two-stage filter design.

2. How much tar does TS Teer STOP actually filter?

We don't give a figure. We have no measurement data that would support a percentage, so we don't state one. The filter is designed to trap tar residue, which you can see in the used filter.

3. Does using a filter attachment change the taste?

Taste is individual — some smokers notice a difference, others don't. We have no survey or test data on this. If you are unsure, start with a small pack.

4. How many times can I use one TS Teer STOP filter?

For up to 6 cigarettes. Replace it after 6 cigarettes at the latest, or sooner if the draw feels noticeably harder.

5. What cigarettes does TS Teer STOP fit?

Regular and king size cigarettes with an 8mm filter end. For slim and superslim cigarettes, use TS Teer STOP Slim 200.

Using Your Filter

6. How do I put the filter on?

Slide the TS Teer STOP attachment firmly onto the filter end of your cigarette. It should feel snug but not require excessive force. Light and smoke normally.

7. When exactly should I replace the filter?

After 6 cigarettes maximum. Replace sooner if you notice dark brown/black discoloration inside, increased draw resistance, or taste change.

8. Can I wash and reuse the filter?

No. TS Teer STOP is a disposable filter for up to 6 cigarettes; it is not designed to be washed. Replace it with a new one.

9. What is the brown/black residue inside the filter?

That is tar residue from the smoke that has collected in the filter. Seeing it is a reminder of what cigarette smoke contains — but it doesn't tell you how much tar still reached your lungs.

10. Does it work with menthol cigarettes?

Yes, as long as the cigarette has the right diameter (8mm, or slim with Slim 200). Whether the taste changes is individual.

Health and Performance

11. Is TS Teer STOP tested and certified?

We cannot point you to any test or certification of its filtering performance, which is why this site does not state any reduction figures. The product information here is based on the manufacturer's description.

12. Does TS Teer STOP filter all tar compounds?

No filter removes all tar. TS Teer STOP is designed to trap part of the tar residue — how much has not been measured.

13. Does the filter make smoking "safe"?

No. No filter makes smoking safe. TS Teer STOP is an add-on accessory; the most effective way to reduce the harm from smoking is to quit.

14. Can I use TS Teer STOP with e-cigarettes or heated tobacco?

No. TS Teer STOP is designed specifically for combusted cigarettes (8mm filter end).

15. How does TS Teer STOP compare to "light" cigarettes?

There is no data comparing the two. "Light" cigarettes have not turned out to be less harmful, partly because smokers compensate with deeper or more frequent puffs — and the same can happen with any filter.

Buying and Pricing

16. Where is the best place to buy TS Teer STOP?

On Amazon, for example Amazon.de and Amazon.com — teerstop.de and teerstop.com link directly to these listings. Customer reviews can be read there as well.

17. Which pack size is the best value?

It depends on how much you smoke: the 1200 Sparpaket for heavy smokers, the 720 Box for daily smokers, the 300 Pack for occasional smokers or to try it first. Compare the current prices per filter on Amazon.

18. Is there a subscription/auto-delivery option?

Amazon may offer "Subscribe & Save" for some listings — check the product page on Amazon for the current options.

Variants and Compatibility

21. What's the difference between Standard and Slim 200?

Standard (8mm) is for regular and king size cigarettes. Slim 200 is for slim and superslim cigarettes. Both have the same two-stage design; only the diameter differs.

22. What do the pack sizes mean: 300, 450, 720 Box, 1200?

Number of individual filter attachments included. One filter = up to 6 cigarettes.

23. Can I use TS Teer STOP with a pipe or cigar?

Not recommended. Designed specifically for standard cigarettes with 8mm filter ends.

24. How long does an unopened package last (shelf life)?

Store the filters in a cool, dry place in their packaging. We don't state a specific shelf life; if the packaging gives a date or storage advice, follow it.
