The Honeywell filter range includes filters for protection against particulates, gases, vapours and combinations of both.
FILTER SELECTION & LIFE EXPECTANCY
Selection of the appropriate filter cartridge and filter combination is dependent on a number of factors, including the type of contaminant, the level of exposure, and the length of exposure. Therefore, this information is presented as an overview only. Consult AS/NZS 1715:2009 selection use and maintenance of respiratory protective equipment. It is impossible to give an exact life expectancy on a filter cartridge for a respirator. This is because the filter life depends on a number of variable factors including the wearers breathing rate, the characteristics and level of the contaminant, the length of time a user is exposed to a contaminant and environmental conditions such as temperature and humidity which could also affect the wearers breathing rate. Saturated or used filter cartridges will leak trace amounts of contaminants to the wearer, which may be detected via odour, taste, and/or irritation – If a contaminant can be detected by any of these means by a user, then filter cartridges should be changed immediately.
