A respirator with the right balance of comfort, fit and breathability. The horizontal flat-fold respirator provides more breathing room than traditional cup-shaped respirators allowing more space for warm air to dissipate. High performing filtration materials provide a minimum of 95% filtration efficiency of 0.3 micron particles. Adjustable nosepiece to customize fit. In addition, the KleenGuard™ Pouch Respirator features two blue headstraps that are made from a patented material that offers a unique combination of strength, softness and stretch. This respirator is made of lightweight materials and its folded design allows for easy storage and portability. In addition to the unique respirator design, the carton is designed to reclose after opening which protects the respirators when not in use. This N95 respirator passes all relevant NIOSH testing protocols. However, please note that NIOSH approval protocols do not include specific tests for respiratory diseases.
