Waterford Mask Systems was founded with the singular goal of creating a respirator that satisfied the pre-defined need for 28 major improvements recommended in the 2010 B.R.E.A.T.H.E. report. These recommendations have gone unfulfilled until now and we at Waterford Mask want to set the GOLD standard for a new higher respirator rating called “B95”. Not only did we fulfill those recommendation but we including a Bio-cidal filter material for extra protection. Saving lives by making the BEST hybrid respirator/mask is a worthy goal and we at Waterford Mask believe we've accomplished this. Check out our website for further information... www.waterfordmask.com
