Fits snugly even when a respirator is worn, and has no open vents, which raises the level of protection; supplied with an easily adjustable head strap.
Made with a facing material that resists the penetration of liquids (Fluid Resistance), suitable for hospital use and able to protect against bodily fluids. The mask is disposable.
Small single-cartridge half mask worn over the nose and mouth to filter hazardous substances in the surrounding air so they do not enter the respiratory system, without obstructing the field of view at work
Protects against vapours, solvents and acid mists. Contains 100 CC. of activated carbon. For spray painting, insecticide spraying, coating and chemical dyeing, maintenance work and degreasing.
Vapour cartridge plus filter pad, protecting against dust, vapours and solvents. Contains 55 CC. of activated carbon. For spray painting, insecticide spraying, coating and chemical dyeing, maintenance work and degreasing. Certified to the Korean standard.
Vapour cartridge for dual-cartridge respirators; Suitable for use with Organic Vapor; Protects against solvent vapours such as paint, lacquer, thinner, toluene, insecticide and oil
Protects against chlorine gas, hydrochloric acid, sulfuric acid, sulfur dioxide gas, chlorine gas and hydrogen sulfide gas (rotten-egg gas). Curved-back design that follows the contour of the face so it does not obstruct the view during work and improves balance.
Protects against solvent vapours, acid gases, formaldehyde vapour and ammonia / methylamine vapour; for areas where several types of gas and vapour are mixed together. The cartridge is square and made of plastic, for use with 3M dual-cartridge replaceable-filter respirators, fitted together with a bayonet attachment.
The 3M model 7502 respirator is made of extra-soft silicone, so the wearer stays comfortable where the mask touches the face while it remains strong and durable, and it comes with the 3M Cool Flow™ Exhalation Valve, which makes breathing easier and vents the heat and moisture that build up inside the mask, keeping it dry and comfortable for long periods of wear.
A disposable 3M dust mask for PM 2.5, made to the US N95 standard with a filtration efficiency of no less than 95%, reliably filtering fine particulates such as PM 2.5 and PM 10 from cement dust, chemicals, metal fume and other pollution. Its electrostatic fibres capture airborne dust firmly, and the N95 mask is tested with 0.3 micron sodium chloride particles under NIOSH requirements.
Certified to the US NIOSH standard; Two braided head straps with two-point attachment for a secure seal against the face; Designed for greater wearing comfort
A device worn over the nose and mouth to keep airborne dust, mist and metal fume out of the respiratory system and to reduce the risk of infection; lightweight, easy to breathe through and not washable.
Protects against dust particulates; certified to Australian standard AS/NZS 1716-1994 and rated in quality class P1, filtering dust and mist smaller than 10 microns with an efficiency of no less than 80 percent.
3M dust mask, model 3M9916, with an exhalation valve; Lightweight, protects well against dust larger than 0.3 microns and against nuisance levels of acid gas and vapour odour
