RESPIRATORY PROTECTION FILTERS FOR HALF MASKS AND FULL FACE MASKS

Respiratory protection filters for half masks and full face masks offer protection against harmful particles, gases and vapours. Filters are divided into two main types: particulate and gas filters. A third option is to use a combination filter, which combines a particulate filter and a gas filter in one.

Most Moldex respiratory masks can be combined with a range of gas and particulate filters. Changing the respiratory protection filter regularly has a significant impact on the safety and lifespan of the mask.

Depending on the manufacturer and model, half and full face masks have either a single or twin cartridge system for connecting filters. In practice, masks that hold a pair of filters (seated on each side of the mask body) are the most common, as these types of masks generally have a better weight distribution and a larger field of vision.

Since each manufacturer offers their own connection system, filters and masks from different manufacturers are not compatible with one another. The exception to this is the standardised EN 148-1 screw connection for gas and particulate filters, though this is not very widely used

 

COMBINING PARTICULATE FILTERS AND GAS FILTERS

Particulate filters and gas filters can be used alone or in combination. When used in combination, the particulate filter is always connected to the front of the gas filter. It is very easy to combine respiratory protection filters using the Moldex EasyLock® filter system, in which a bayonet connection on the mask body enables the easy installation of either filter types. However, the really unique thing about this system is an additional bayonet connection on the front of the gas filter, which enables the particulate filter to be mounted directly on top of the gas filter, without the need of any additional filter holders or adapter which are required by most other filter systems.

 

HOW DO PARTICULATE FILTERS AND GAS FILTERS WORK?

Particulate filters combine two different filtration mechanisms: mechanical filtration and electrostatic charge. Mechanical filtration traps larger particles, a bit like a sieve. The electrostatic charge draws smaller particles towards it and traps them in the filter material.

Gas filters are made from cartridges filled with activated carbon, which binds gaseous pollutants through absorption. This mechanism of action is comparable to a sponge soaking up water.
