BASE CAMP Reusable N Plus Dust Mask, 360-Degree Seal with MNL Material Respirator Mask with 6 Filter-Face Mask for Dust, Pollen, Welding, Construction, Sanding, Yard Lawn, Paint, Woodworking

This covered my nose and mouth from the pollen when I was mowing the yard and pasture.

I can wear this for long periods of time comfortably. I like that it is reusable, and the filters are replaceable. I work with wood, and sometimes fiberglass. This protects my airways really well.

Sent me used respirator make sure it's not been used or opened

Filtration works OK but I had a hard time trying to adjust its fitting to keep the strap stay behind my head.

Wear under weld helmet without my glasses steaming up. New glue smell is bad but fading. No headaches from smell so I guess all is good

Do take heed of the no returns policy because it also applies if you get a defective one like I did. It's completely lopsided, and thus doesn't seal or give dust protection (or any protection at all), which makes it functionally useless. Amazon was the one to do a one time refund. So I decided to try it on after that, and while the size wasn't bad for me since my head is small, the ear loops are uncomfortable and I can tell they'd come off easily if I was moving around while using it. I had it shipped in the manufacturer packing, but it wasn't even sealed, just a Ziploc style bag with the mask loose inside it. Not that I think anyone would use it before I received it, but they could have if they wanted. It's so bad that the threads were already coming loose despite being unused. How cheaply made is this thing? Garbage, don't waste your money, seriously.

The fit on this is not good. It seems designed for someone with a very specific kind of skull shape. Like, a small head with very low-set ears.The strap keeps trying to slide down the back of my neck, which leads to the ear holes putting a very uncomfortable downward pressure on the tops of my ears. I would return it if I could, but instead I will modify it by adding another strap to go over the top of the head for better support and comfort.Other than the fit, the product is as advertised. Soft, breathable fabric would be comfortable to wear all day (if not for the issues with fitting). Filtration is good too, keeps wood dust out of my airways without making me struggle to breathe. I would give this a 4/5 if not for the terrible fit. I suggest testing any design changes on a variety of head sizes and shapes to avoid this problem in the future.

works great while wearing safety glasses. Does not fog them, and neck strap is a game changer.
