KN95 Respirators (5 PCS) | 95% Filtering Personal Protective Equipment (PPE)

$14.99

  • Most commonly used personal protective equipment (PPE) to filter 95% of non-oil-based aerosol in the air and prevent exposure to pathogenic biological airborne particulates
  • Recognized by the Food & Drug Administration (FDA) as suitable replacements for American Standard NIOSH certified N95 faces during emergency shortage periods
  • 3 Layer Construction with flow rate of 85 L/min, inhalation resistance of less than or equal to 350 Pa, exhalation resistance of less than or equal to 250 Pa, and total inward leakage of less than or equal to 8% leakage (arithmetic mean)
  • Respirator masks should not be re-used with multiple encounter with patients although extended use is permitted as long as it does not degrade respirator protection
  • Respirators must be discarded after use during aerosol generating procedures or contaminated with fluids from patients or after close contact with patients infected with infectious diseases


KN95 disposable respirator masks, also known as filtering facepiece respirators (FFR), are equivalent to NIOSH-certified N95 respirator masks under the Chinese standard for filtering 95% of small airborne particles and preventing exposure to pathogenic biological airborne particulates. It is one of the most commonly used personal protective equipment (PPE) by medical professionals while in contact with infected patients and while performing medical procedures.
