Please select the correct size according to the sizing chart found in the photo gallery for this product.

NOTE: For proper mask fit, faces must be clean shaven.

Facial hair, sideburns, bangs and headwear may prevent a protective facepiece from forming and/or maintaining a tight-fitting seal on someone’s face. It is recommended the user be clean shaven and/or hair pulled back for sizing and using the respirator to ensure an appropriate seal.

To ensure you have selected the correct size you should perform a negative pressure test. The negative pressure test can be performed by putting the mask on your face, breathe out, then block the inhalation valve and take a deep breath. For the FM50 you will need to block both inhalation valves before taking a breath. The mask should collapse to the face. If you experience a tight seal to your face then the mask has the right fit.

If you are still unsure of your size or are certain you are going to be in a hazardous environment and need to ensure the most accurate sizing you may purchase a Sizing Tool.

*Except in the rare case of defective product. Please contact customer service for further instruction in this instance.
