Whatever the job, it's good. Dust or fumes I have never smelt anything come through no matter the density of the hazard. This is the only one I will ever buy.

Purchased for spraying cellulose car paint which needs carbon filter for the fumes and dust filter for overspray. Respirator worked great, no taste or smell whilst spraying in a small booth and no headache which cellulose causes. This unit is disposable after 30 days use, the filters can't be replaced. But good for 1off project.
Don't forget eye protection as cellulose is an irritant and very uncomfortable.
Recommended to be safe.

Carbon filter only lasts about a month once the sealed bag has been opened. After this, it's effectiveness at filtering fumes such as isocyanates (the main component in catalysed hardeners) declines.Since isocyanates are one of the most dangerous neurotoxins known to man, you don't want to take the risk of building an intolerance to them. If using for this type of work, I'd follow the advice on the data sheet closely. That said, it's a great mask, good fit and comfortable. I use one all the time.
