Respirator subscription

Anytime I go into the attic or near dust of any kind, I put on one of these 3M Cool Flow respirator masks. They are comfortable and they really help me from having a sneezing fit. My daughter uses them for her art projects. Amazon sells a 10 pack for $15, but I use Amazon’s Subscribe and Save and get a 10 pack sent to me every six months for $14. — MF
