DrägerX-plore 6300 full-face respirator mask with Rd40 thread connection, NIOSH-approved, 40mm filter connection

I was a fumigater at the ports for boats that had grain soy bean ect I had to wear these when fumigating in the peak of summer and the cold of winter they work it did suck during summer wearing pants and hoodie inside a suit but they get the job done I used to work for degesh. I figured Amazon could use a review of someone who has actually relied on this mask. I would recommend.
