“I bought this mask as an N95 mask for my son to wear when he helps my husband with construction projects like sanding and staining. I had no idea how important this mask would be. My husband wore this mask to protect his lungs while he tried to save our house from a brush fire. The firemen were all asking him about it when they arrived. The only problem was that the medium was a little small on a grown man. I will be ordering a larger size for sure.”
