RZ Mask Universal Dust/Pollution Mask F1 Filter 3-Pack - Large

Excellent! Perfect for protection from the flu pandemic of 2020! Jesus is coming and He is Lord and our Savior

Great for working in the shop when grinding. Also, good when installing fiberglass insulation.

Didn’t fit the original mask. Replacement masks were much smaller than what it needs.

Arrived way ahead of schedule and 0ackaging was in great condition. Awesome price for 3 of these things.

It does what I wanted it to do

but didn't like the mask they can with.

Better filters than the Miller welding resporator.
