Please kindly note that variances between masks are expected, as they are manufactured in batches and each batch can differ slightly from one another. This does not take away from the quality or protection level of the mask and whatever rating or certification they have been given (i.e., ASTM Level 3 or N95) remains true.

 These variances can include the thickness of the ear loops or the tightness of them, the feel of the material, etc. If you experience any of these variances and your product is manufactured by Dent-X Canada, please contact Dent-X Canada directly here. Our representatives will have no further information and will provide the same response.

If your product was not manufactured by Dent-X Canada, please reach out to and one of our representatives will be more than happy to provide some further insight.
