When using breathing masks it is very important to use the right filter for whatever job you're completing. If you are a bit confused about what filter you should be using, don't dismay. This easy guide to Sundström filters will help you choose!
The difference between gas and particle filters: Because particle filters and gas filters work in very different ways. A particle filter is a very fine fibre mesh which captures dust particles while letting clean air through. But it will not stop gas or vapour from getting through. A gas filter contains activated carbon, which works like blotting paper: it absorbs the gas molecules and binds them to the carbon before they can reach your lungs. However, the carbon is not an effective barrier to fine dust particles.
A Single Particle Filter: There is only one particle filter in the Sundström range. The particle filter protects against all types of coarse and fine particles, such as dust, fibres, smoke & fume, aerosols (wet particles; spray, mist), mould, bacteria, viruses & other solid particles
Several Gas Filters: There are several different gas filters for different types of gas. The various filters can be recognised by their colour coding* on the label.
Colour Coding of Filters: Your Sundström filters are colour coded and marked with a letter code. Combination filters have more than one colour code and letter code.
There are two major categories of filters: Gas filters & Particle filters. Gas filters protect ONLY against gas or vapour. Particle filters protect ONLY against particles. If the atmosphere contains a mixture of gas and particles, both filter types must be used.
Hopefully this guide answers a few of the burning questions you may have about filters.
Always be safe when working around particles and gases AND when in doubt, please just ask!
