Bests & Worsts Reviews from Amazon

I wear these masks for approximately 18 to 20 hours of the day at work. I am a first responder and I switch them out approximately every 8 hours. I have worn them since Under Amour released them on the market and I have not gotten Covid. I wear them religiously and only take them off for bathing, eating, brushing my teeth, or when I have to don an N95 mask for actual covid positiive emergency calls. I wear these at the fire house without fail and they have not failed me yet.
