Absolutely deduct. I'm using most of my supply of this stuff for work!! I'm a prophet: I've been double-masking since day 1. I use a KN95 with a blue "medical" mask over it. I dispose of blue medical after (almost) every closing, and use the KN95 for a few days. The KN95s are expensive and far more protectivwe, so I feel the blue ones allow me to use the better mask longer. And, yes, they will be a business deduction. |
