Do these filter out cigarette smoke?

I've successfully used them to filter out other "herbal smoke" but I can't say anything about cigarette smoke seeing as I've never tried it. But if you're looking to filter anything that's legal in colorado, it should work pretty well. Activated charcoal filters out everything

No they are not, they are made out of very thin paper, not great. Ok, If you can't find the original filters, Good luck on your quest :)

It does "help", but does not completely filter anything. I have some serious lung health concerns so I use these when I fly or go into crowded areas. So far they've helped to keep me from getting ill.

Yes. I used to live with a heavy smoker and had a Honeywell HEPA filter system at the time. As long as you are on top of replacing filters it makes a huge difference.

Good question. I don't smoke and don't have any visitors that smoke either, but from everything I've seen it should help a *lot*. Of course realize that the smoke particles will plate out on your floor, walls and furniture as they are pulled out of the air. I doubt you'd find any air purifier that would do a *better* job with cigarette smoke. (it would be interesting to compare it to an air filter though)

I have cats and use these filters to clean the area around the litter box. I've washed the filters (I bought 2) a few times each and don't see any noticeable decline in vacuum from when I first bought them. A lot of nasty stuff comes out in the water when you wash them and they return to a slightly gray shade of white, so I think most of the litter dust is successfully removed.

The short answer is: YES--these are HEPA filters. HEPA definition: "To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of 0.3 m particles." These filters are rated to remove particulate down to 0.3 micrometers at 99.97% efficiency (according to 3M's website). These cartridges qualify as HEPA filters.

Yes they do (there are 2). One of the filters (which is a black plastic mesh material) is reusable in my opinion too fyi. I just suck all of the dust out of it with a vacuum hose and reuse it (or it could be washed and dried).

No. There are four filters. You out your regular cigarette with the filters.

ventilation air filters, well...they filter air, generally. Some work better than others.

This filter is for "particulates" i.e. particles. In other words, DUST.It does not filter vapors i.e. GAS. You need a gas filter to filter out vapor/gas. The charcoal in these filters helps to eliminate odors and that makes working in smelly environments more comfortable; however, it does not actually filter out any vapors or gases--it just reduces the smell.

It'll scrub the air including cigarette smoke; the charcoal filter eliminates odor and ionizer freshens air. So yes this unit will help with cigarette smoke. However any smoke gets embedded into furniture uphostery; etc; is another story.

I smoke Marlboro but I believe that it is possible to use the filter for slim cigarettes

Angelo, can not answer that true-fully because we do not smoke--I can tell you that once I started using It the dust in the back room was eliminated. It does have two filters-one Is a He-pa filter which traps the tiniest of particles.

Come with basic filter but you can buy filters specifically for smoke. I love this product I'm vary happy with it.

Even good home air cleaners like these are only going to be moderately effective when used in a very smokey environment. They will, to some extent, re-radiate whatever they have been filtering.

Yes they do a pretty good job overall of keeping particulates out. I Use them for cement dust. Nothing is 100% when it's that fine.
