I purchased a 20-pack box of 3M's particulate respirators N95 (model 8210) online from Ozmedical using PayPal effective 2-25-21. Box was timely delivered in good condition to my home address in San Antonio, Texas on 3-4-21 via USPS first class mail. I am satisfied with the 7 day turn around (online purchase to ground delivery) with free shipping. I was also pleased with Ozmedical's online shipment tracking support, enabling me to monitor shipping progress throughout. All things considered, Ozmedical's price for these masks was both reasonable and very competitive. I've checked and these masks appear to be the genuine product of 3M. All in all, I am very happy with Ozmedical, plan to use them again, and recommend them as a reliable source for medical equipment supplies.
