MINGYI 9501V home health care 50 KN95 masks GB 2626-2019 95% filtration valve

Product purpose and intended users

This pack contains 50 white 3M 9501V+ respirators that meet the GB 2626-2019 KN95 standard. They are designed for adults who need a disposable mask with a minimum 95% filtration rate against mechanically generated particles, nuisance-level organic vapours and low-vapour-pressure agricultural chemicals. The integrated valve and adjustable noseclip suit extended wear during machining, automotive work, gardening or outdoor activities such as hiking and climbing.

Valve limits and standard scope

The one-way breathing valve lowers exhalation resistance but does not filter expelled air, so the mask is not suitable for sterile fields or situations where source control is required. The GB 2626-2019 KN95 rating covers solid and liquid aerosols and the listed nuisance-level vapours; it does not certify protection against gases, high-concentration vapours, oxygen-deficient atmospheres or oil-based mists beyond the standard’s scope.

Fit and compatibility checks

Verify that the adjustable noseclip and soft inner shell create a complete seal on your face before relying on the respirator; facial hair or an atypical face shape may prevent a proper fit. Confirm that your workplace or activity does not require a valve-free mask or a higher protection class than KN95. Each mask is individually packaged and intended for single use; replace it when breathing resistance increases or the mask becomes damaged or soiled.
