      This respirator protects covid
      This respirator is very good, it protects against covid and has a respirator, but if the person who uses it has covid they can exhale particles with viruses.

        Great features
        Im looking to buy 280 boxes each month for 12 months
          Great Product - Zero Availability
          I've been rotating the same 4 or 5 N95 masks for MONTHS when I used to use maybe two per WEEK! When are companies like 3M going to start producing enough masks so they can be prioritized for workers on the front lines of building and remodeling your houses and offices and not just those on the front lines fighting Covid-19 wherever that is happening. Please watch for mesothelioma and other respiratory illness to spike once this whole Covid-19 thing is over OR start making enough masks to go around PLEASE.

              cool flow is a good name since the mask doesnt make you sweat bullets and the filter is very strong. highly recommend
