ASTM Level 3 Procedure Mask - 98% filtration - Disposable - pack of 50

Excellent timeframe for delivery. Product as expected.

Linda Doty
Great Disposable Masks

These ASTM Level 3 Procedure Masks are rated to deliver a high level of protection. They provide good face coverage and are easy to breath in. They are the perfect first layer for double masking. The elastic ear straps are a little long, so I put a knot in mine. I gave 4 stars instead of 5 because the first package I ordered (from another distributor who no longer carries these) were a little larger, and the folds were spaced differently. All things considered, the differences are small, but my family loved that first box, and we wish the product hadn’t changed. Still the best mask, and we will continue to order.

Thanks for reviewing this product. Your feedback is valuable to us as we are constantly strive to offer the best quality of products for all of our customers. Please let us know if there is any other products we can help you find in the future!

Wish the nose piece offered a more secure fit. Defeats the purpose when I need to keep pinching the wire while having it on.
