The respiratory filter plays a key role in protecting professionals exposed to hazardous substances. Used in industry, chemicals, food processing or construction, it effectively filters particles, gases and vapours. Filter cartridges are suited to each hazard and keep teams safe in demanding environments.
What standards apply to respiratory filters?
Respiratory filters are subject to European standards that guarantee their effectiveness and safe use:
EN 143: covers particle filters, with classes P1, P2 and P3 according to filtration level.
EN 14387: applies to filters against gases, vapours and combinations, with a colour code for each type of contaminant (A, B, E, K, etc.).
EN 12941 / EN 12942: govern powered filtering systems, particularly for powered-ventilation masks.
EN 136 / EN 140: set out the requirements for full face masks and half masks, guaranteeing filter compatibility.
Meeting these standards makes it possible to select equipment suited to every professional environment.
What types of respiratory filters are there, and for which sectors?
There are several types of respiratory filter, each meeting specific needs depending on the sector:
Particle filters: recommended for industry, construction or agriculture, they protect against dust and fibres.
Gas and vapour filters: essential in chemicals, painting or waste treatment, they filter specific volatile substances.
Combined filters: suited to mixed environments such as food processing or industrial maintenance.
3M filter cartridges for respiratory protection offer a reliable solution for many trades.
For complete protection, discover the range of respiratory protective masks suited to every professional use.
How should respiratory filters be maintained?
Thorough maintenance of respiratory filters is essential to guarantee their effectiveness. It is advisable to:
Check the condition of filter cartridges regularly and replace them as soon as they show signs of saturation or clogging.
Clean non-filtering parts (masks, seals) with a soft cloth and a suitable detergent, without wetting the filters.
Store filters in a dry place, away from moisture and chemicals.
Observe the lifespan indicated by the manufacturer and note the opening date to avoid using an expired filter.
A visual check before each use is recommended to ensure user safety.
What specific points should be considered for respiratory filters?
Choosing a respiratory filter should take several technical and contextual criteria into account: compatibility with the mask used, suitability for the nature of the substances to be filtered, and duration of exposure. It is important to check compatibility with other PPE, such as glasses or helmets, to guarantee a comfortable, secure fit. In environments with a high concentration of pollutants or low oxygen levels, using a powered system may be necessary.
Matching the filter to frequency of use and hazard intensity helps optimise the safety and performance of teams on site.
