The only NIOSH approved N95 respirator mask that we currently offer is the SoftSeal N95 Certified Respirator Mask and for good reason. The SoftSeal N95 Respirator provides for a superior seal to your face with silicone, that is essential to a properly fitted and effective respirator mask. Without a solid seal to your face, you are left exposed and the benefits of a respirator mask are not seen and that is why we choose SoftSeal.
