NICSTOP Duo Double Filtration Cigarette Filters - 10 Packs (70 Filters)

Its not efficient in striping out the tar from the smoke. It last a long time because it does a poor job so that is not a good thing. The cheaper tartrap although they last only 4 cigarettes they do so because they catch more of the tar.

They help to reduce the number of cigarettes I smoke and help stop coughing.

Good filters but a few of them feel and are clogged!

this product really works since I have used it I noticed I can breath better..Not saying ur not getting some nicotine in ur lungs but it does keep a lot out. Now you can't order them no more. Why can't you get them no more. These are the best filters out there and they quit selling them

I like that I can see the amount of tar and nicotine pulled from the cigarette. I’m using the product to wean off nicotine to stop smoking.

Been using these for about 5 years now..can see all the bad stuff that could had gone in me..no smokers cough ,no yellowing or anything..I will keep using..only thing is bit pricey

I order these filters all the time. It's crazy to see the black gross tar that goes into your lungs. These filters catch it and you can see it.

I did not give them a lot of stars because I have bought these in the past and a few out of what I bought had been unusable,the plastic holes seemed to be not opened while being made.with this order there came to be at least one in every box that was bad.
