Dust masks (disposable)
Dust masks – most commonly known as disposable masks are a bit special respiratory protective units. Contrary to classic equipment, they are made for single use and the whole facepiece is made of air purifying materials.
How to choose a dust mask
FFP1, FFP2 and FFP3 dust masks
FFP (Facepiece Filtering Particules) Disposable dust masks are air purifying devices used both by professionals and private individuals against fine particles, solids or liquids, viruses and bacteria.The 2001 update of the EN149 standard defines 3 eficiency classes based on the maximum penetration value through the device, or the proportion of particles that the mask lets pass:
- FFP1 mask: stops at least* 78% of particles
- FFP2 mask: stops at least* 92% des particules
- FFP3 mask: stops at least* 98% des particules
* All available FFP masks on our website are way over this standard, offering form 94% for FFP2 masks up to 99.97% for FFP3 masks.
Exhalation valve
For respiratory comfort and hygiene, the exhalation valve is very important. It allows proper evacuation of hot and moist exhaled air, thus avoiding heat accumulation and condensation. That way the user can stay in a cool environment.
FFP1 dust masks
It is the first level of protection (stops 78% of particles minimum), they are more suitable against dust and particles of intermediate sizes such as silica, coal, soft wood or filings of iron metals. They are suitable for DIY and occasional small dusty woodwork jobs .
| Activity sector | Activity | Type of particles |
| Crafts, DIY, handiwork | Miscellaneous works | CWood chips, metals, dust and fibers |
| Construction | Foundations, concrete handling, insulation work | Concrete dust, fiberglass |
| Metal processing | Sawing, drilling | Metallurgical dust |
| Metal processing | Drilling | Metallurgical dust |
FFP2 dust masks
It is the intermediate level of protection (stops 92% of particles at least), they are more suitable against fine particles such as sanding dust (wood, metals), fog and aerosol paint and some mushroom pores. They are particularly popular in sandblasting, grinding and spraying applications.
Classic FFP2 dust masks
| Activity sector | Activity | Type of particles |
| Woodworking | Sanding, paint stripping | Fine particles, wood dust Fine paint particles |
| Metal treatment | Stripping, grinding, sanding, soldering, welding, painting | Rust, corrosion and metal dust, sand and dust, welding fumes, paint particles, spray varnish |
| Construction / demolition | Building | Metallurgical dust |
| Metal treatment | Drilling | Dust from concrete, plaster, rock wool and tiles, fine dust from plaster |
FFP2 odor-free masks
The FFP2 version (intermediate protection blocks a minimum 92% of particles) with an additional layer of activated carbon is able to trap organic vapor smells.
| Activity sector | Activity | Type of particles |
| Crafts | woodworking | Glues, paint, varnish, aerosols |
| Waste disposal | Dusty environments cleaning, floor sweeping, waste & wastewater disposal | Smelling dusts, bacteria, fungi |
FFP3 masks
It is the highest level of protection (stops a minimum 98% of particles), they are ideal against very fine particles like asbestos (level 1), ceramic fibers, viruses (avian flu, H1N1 flu, etc.) and bacteria. They are popular for all work generating very fine particles (asbestos removal, medical waste, metallurgical fumes, etc.). It is the most effective protection class and therefore to be preferred.
| Activity sector | Activity | Type of particles |
| Woodworking | Wood coloring (dye containing copper or chromium) | Paint mist |
| Construction, mining | Zinc, aluminum, stainless steel, manual arc welding | Metallurgical oxide fumes |
| Waste disposal | Medical waste | Virus, bacteria Mushrooms |
| Epidemics | Personal protection | Virus, bacteria Mushrooms |
Dust mask usage restricitions
Even if a dust mask offers a very interesting protection / comfort / price ratio, it only protects its user against particles. It thus cannot be worn if gases or vapors are present in the concerned atmosphere. In this case, the user must select a half mask with combined gas and particle filters.
Beyond concentrations over 30 times the OEL (occupational exposure limit value), the efficiency of a FFP3 disposable mask is compromised. User shall then select a powered air purifying respirator or a mask with a filter cartridge. Lastly, if the nature of the pollutant and/or the oxygen rate in ambient air is unknown, every air purifying protective equipment is to be avoided and replaced by an atmosphere supplying respiratory protection..
