A1B1E1K1 Filter Pair

These cartridges are designed for use with respiratory protection systems to filter hazardous airborne contaminants. They combine particulate and gas/vapour filtration in a single unit for versatile protection. The black housing contains activated carbon and specialised media to target specific chemical threats. Each pair is intended for attachment to approved mask models via standard threading. Proper fit and seal are essential for effective performance during use. Filters should be inspected before each use for signs of damage or wear.

The filter provides defence against a range of organic vapours commonly found in industrial settings, including solvents and fumes. It also neutralises acid gases such as chlorine, hydrogen chloride and hydrogen fluoride that may arise during cleaning or processing tasks. Sulphur dioxide and ammonia are additionally captured, making the cartridge suitable for environments with multiple chemical hazards. Particulate filtration captures dust, mists and fumes to complement the gas protection. This combination allows workers to remain protected in mixed-exposure scenarios without changing cartridges. Breakthrough times vary based on concentration and breathing rate.

Intended for use with half face masks like the 5500 and 7700 series, and full face masks such as the 7600 model, these cartridges attach securely via bayonet or threaded connection. They are not standalone devices and must be used with a compatible facepiece to ensure protection. Environmental factors like high humidity or elevated temperatures can reduce effective service life. Users must monitor for breakthrough signs such as smell, taste or irritation, which indicate immediate replacement is needed. Reuse of saturated cartridges is unsafe and may lead to exposure. Always follow manufacturer guidelines for change schedules and storage.
