Questions and Answers for HDX N95 Disposable Respirator Valve Box (15-Pack)

A:  No, it is not recommended to be used with a beard.

A:  Most facial hair compromises the seal of form fitting respirators. A trimmed mustache is the only safe facial hair for this respirator.

A:  One of our guys wears them and has no issue. Depends what kind of dust and how much you want to keep out...

A:  Yes you can. I happen to have a nice Goatee. I have no problem with any dust intrusion when using my table or Skil saws.

A:  Some of my guys do, but it won't seal well.

A:  The APF for this product is 10.

A:  Very good

A:  The course particulate element would be the only part of smoke it would filter. Gases and the really fine stuff will go right through. Smoke requires a whole new level of protection to be significantly effective. For smoke, I would not recommend this level of protection.

A:  This product protects from smoke and other inhalants.

A:  yes very so.one of the worker use them for smoke that had got into the vents.

A:  I have use my same respirator mask about 4 to 5 days, before disposing of the old one.

A:  There are two things that determine how long you can wear it... comfort (this fails compared to other products) and effectiveness. You can tell a mask isn't effective anymore if it is challenging to breath through or you are smelling things you shouldn't be smelling. How long a mask lasts is going to vary wildly based on what situation it's being used in.

A:  No sensor. You have to use common sense based as you said on the type job. But they are cheap so erring on the side of caution is not a big issue

A:  Our guys wear them until lunch and then get a new one. This is with considerable dust.

A:  As you noted, the length of service is defined by the relative conditions of use. I personally have found the mask functions well even in some really dirty conditions. My method to the madness is to look at the overall color of both sides. Comparison with a new clean mask will tell you how dirty it is. If the color change is only slight, I continue usage. When it gets grungy I replace.

A:  very much so. that is why I brought them, just for the mold. I will be buying them again and again

A:  I would say not. Get a respirator type and keep it tight.

A:  Yes it does. OSHA recommends either a N, R or P-95 respirator be used in Mold clean up. N stands for Not Oil resistant so as long as you are not using to filter any oils out of the air this filter will work great. It will filter 95% of particles in the air.
