| A recent article stated that although masks may filter tiny particles as advertised, they do not take out harmful gases and vapours unless the masks has an activated charcoal element within it.
Air pollution âVillainsâ are a combination of the following:
Nitrogen Oxide (NOx)
Sulphur Dioxide (SO2)
Organic Vapours (VOCs)
Low Level Ozone (LLO)
Particulate Matter (PM)
BE SMART, BE IN THE KNOW
Respro® provide masks with 'combination' filters for the filtration of all of the above. The DACC (Dynamic Activated Charcoal Cloth) in our filters is Ministry of Defence developed and does what it says on the can. |
