The LA SHEEN Reusable Protective Dust Face Mask is a very solid product.
You get three face masks, two packs with five pieces of extra activated carbon filters and a total of ten valve filters.
The breathing valves help eliminate heat and moisture and reduces carbon dioxide accumulation and more.
As for the activated carbon filter, judging by the type, this appears to be PM 2.5 activated carbon filters, which have five protective layers of non woven cloth, meltblown cloth, activated carbon cloth, meltbown cloth and again a nonwoven cloth layer.
One thing I noticed is that the activated carbon filters tend to have a strong smell that some people don’t like, but with these, I’m not smelling any strong carbon odor.
As for the mask itself, I felt the ear loops work great, but some with bigger heads may feel the ear loop would be better if it was adjustable. What is adjustable is a velcro strap that goes behind the neck/head which is great.
But why I give the LA SHEEN Reusable Protective Dust Face Mask high marks is the fact you get ten valve filters. Most masks like this only give you extra activated carbon filters. So, the fact that you get many of both and a total of three masks is a plus!
The LA SHEEN Reusable Protective Dust Face Mask is highly recommended!
