Where are these items manufactured? 

We are proud to offer 100% American-Made, NIOSH-approved N95 respirators and ASTM Level 1 and Level 3 procedure masks.

Which masks are used for "Double Masking" and how do I get the most benefit from my masks?

The Centers for Disease Control have released an updated guide on the proper way to practice "double masking." Click here to see the guide on the CDC's website. 

"Double masking" is not intended for N95 respirators. They should be worn alone and with a tight seal to the face. See the guide below for instructions on wearing your N95.

Procedure masks rated Level 1 or Level 3 are the best options to be worn in "double masking" situations. The procedure mask should be work closest to the face, with a cloth mask worn over to help create a tighter fit. Do not combine two procedure masks, as they are not designed to fit tightly and wearing more than one will not improve fit.

What are NIOSH and ASTM? Why are they important?

NIOSH is the National Institute for Occupational Safety and Health, a division of the Centers for Disease Control which certifies that manufacturers of N95 respirators meet certain testing and quality control procedures to protect wearers. All N95 respirators sold by Rhino Medical Supply have NIOSH approval. The complete list of approved NIOSH N95 respirators can be found here.

ASTM, formerly known as American Society for Testing and Materials, is an international standards organization that develops technical standards for a wide range of materials and products. All Level 1 and Level 3 procedure masks sold by Rhino Medical Supply meet or exceed the ASTM F2100 - 20 technical standard.

What are the proper instructions for wearing an N95 Respirator?

  1. Cup the respirator in your hand, with the nosepiece at your fingertips, allowing the headbands to hang freely below your hand.

  1. Position the respirator under your chin with the nosepiece up. Pull the top strap over your head resting it high at the top back of your head. Pull the bottom strap over your head and position it around the neck below the ears. 

  1. Place your fingertips from both hands at the top of the metal nosepiece. Using two hands, mold the nose area to the shape of your nose by pushing inward while moving your fingertips down both sides of the nosepiece. Pinching the nosepiece using one hand may result in improper fit and less effective respirator performance. Use two hands.

  1. Perform a User Seal Check prior to each wearing. To check the respirator-to-face seal, place both hands completely over the respirator and exhale. Be careful not to disturb the position of the respirator. If air leaks around the nose, readjust the nosepiece as described in step 3. If air leaks at the respirator edges, work the straps back along the sides of your head.
