3MReusable Respirator, Half Face Piece 7503, Use with Bayonet Cartridges/Filters (Not Included) for Gases, Vapors, Dust, Large Size

More better than the previous model.

It is a genuine product and 6001 and 2097 cartridges fit well. I gave 4 stars because the silicon is very smelly.

Justo lo que necesitoY llegó antes de tiempoMuchas GraciasMuy buena calidad

Tested this by putting it on without any filters and covering the holes with my hands. Even though I have a beard aboslutely no air was getting in there, completed suction vacuum (a bit scarry actually). I was worried about the exhale valve leaking by...it didn't. Also, another thing I liked about this one is the exhaust goes down and is not directly exposed to outside. Even if a few air molecules were to infiltrate from the exhaust valve it would only be the last few from your last exhale anyway. Works good and is comfortable. Mind you this is not a review from long term useage.

Ha sido comprada por el tema del Coronavirus porque las demás mascarillas de cartas eran demasiados caras y sin sentido vaya. Esta es muy cómoda y protege muy muy bien, es praticamente eterna si se cuida y limpia. La ventaja de poder montar cualquier tipo de filtros no tiene igual....a mi ha sido genial.

Worn it for welding and metal melting so far and found it to ne confortable. I kept it for 3 hours straight without feeling the need to remove it. Great fit for large faces.

Muy buen producto...
