North N06575852L CART/FILTER A HG P3 CLASS 1

Filter life depends on a number of variable factors including the wearer’s breathing rate, the characteristics and level of the contaminant, the length of exposure to a contaminant, and environmental conditions such as temperature and humidity which could also effect the wearer’s breathing rate. Saturated or used filter cartridges will leak trace amounts of contaminants to the wearer which may be detected by odour, taste, and/or irritation – If a contaminant can be detected by any of these, the filter cartridges should be changed immediately.
