General about Protection Factor

Protection factor is a measure of how much the content of pollutants decreases with protection. A protection factor of 100 reduces the level of pollutants in the ambient air 100 times, for example from 50 to 0.5 ppm. At the same time, the protection factor indicates how many times longer you can be, e.g. in hazardous gas, compared to without protection. For example, protection factor 500 gives that one hour without protection corresponds to 500 hours with protection.

Protection factor / Exposure

The studies that have been done on the garments have analysed the exposure of hazardous PAHs. Exposure is the opposite of the protection factor, so if the exposure is, for example, 1/1000, the protection factor is 1000.

CPP's activated carbon is both highly activated and has a significant dynamic adsorption capacity. This means that it has a high absolute capacity, and at the same time a high dynamic capacity through its well-balanced system of both larger pores which function as transport pathways and smaller pores which binds the molecules. CPP’s activated carbon has a high adsorption capacity even for low gas concentrations. The absolute adsorption capacity of gaseous PAHs has been found to be so high that the activated carbon retains an adsorption capacity even after 24 smoke dives (10 hours) with intermediate washes.

Unlike other activated carbon, CPP's carbon is also very mechanically stable and does not crumble under pressure or wear.
