MINGYI 9541V KN95 Activated Carbon Mask with Valve Gray 20 Pieces

SKU CH-BBQX-10FNC MPN 9541V

KN95 activated-carbon respirator with valve filters at least 95% of particles for 20 uses

  • KN95 filtration ≥ 95 % meets GB 2626-2019 standard
  • Activated carbon layer absorbs organic vapours and odours
  • One-way exhalation valve lowers breathing resistance
  • Adjustable noseclip and soft inner shell improve face seal
  • Pack of 20 masks supplied individually wrapped

Pack contents and intended use

This pack contains 20 gray KN95 respirators with an activated carbon layer and an exhalation valve. They are designed for adults who need particulate filtration during tasks such as machining, automotive work, spraying pesticides or similar agricultural chemicals. The masks meet the GB 2626-2019 KN95 standard with a filtration rate of not less than 95 percent.

Fit, valve and carbon layer

An adjustable nose clip and soft inner shell help the mask seal against a wide range of face shapes. The one-way breathing valve lowers exhalation resistance for smoother breathing during extended wear. The activated carbon layer addresses nuisance-level organic vapours and low-vapour-pressure chemicals rather than providing gas-cartridge protection.

Sustained wear behaviour

The valve continues to vent heat and moisture so resistance stays low over long shifts. Filtration performance remains at the rated level as long as the filter media is not clogged or damaged. The masks are single-use; they are not designed for washing or for environments that require a higher protection class or a supplied-air system.

Questions about this item

How long does the activated carbon layer remain effective against organic vapours during continuous wear?

The mask is rated for nuisance-level organic vapours and low-vapour-pressure chemicals; service life depends on contaminant concentration and humidity, so replace when breathing resistance increases or odour is detected.

Does the one-way valve reduce heat build-up during all-day use in warm conditions?

The independent one-way breathing valve lowers exhalation resistance, which helps release warm, moist air and keeps the interior cooler during extended wear.

Is any fit-testing equipment or additional filter cartridge required before using these masks?

No extra cartridges or fit-test kits are needed; each mask has an integrated KN95 filter, adjustable noseclip and valve, and is individually packaged for immediate use.
