The Portwest P921 ABEK1 Gas Filter is designed for professionals working in environments with exposure to organic and inorganic acid gases and vapors, sulfur dioxide, and ammonia derivatives with a boiling point above 65°C. Its key benefit is providing reliable protection through a secure bayonet connection and balanced twin filter design, enhancing comfort.

Replace the filters if you experience increased breathing resistance, if they become damaged, or if you detect any odor or taste of contaminants. Specific replacement intervals depend on usage and environmental conditions.
No, the P921 ABEK1 filter is not designed for protection against carbon monoxide. Specific filters are required for CO protection.

'ABEK' refers to the types of gases the filter is effective against (A: Organic Gases, B: Inorganic Gases, E: Acid Gases, K: Ammonia). The '1' indicates the filter's protection class, signifying its capacity and performance level.
No, the P921 filters are specifically designed with a Portwest bayonet system and are only compatible with designated Portwest respirator models.
Ensure you are using a compatible Portwest mask model (P500, P420, P430, P431). Check for any debris obstructing the bayonet slots on both the mask and the filter. Realign and push firmly before twisting clockwise until it clicks.
This may indicate the filter is saturated and needs replacement. Check for any blockages in the filter or respirator valves. Ensure the mask is properly fitted to create a seal.
The filter may be nearing saturation or has absorbed substances beyond its capacity. Replace the filter immediately. This indicates the filter is no longer providing adequate protection.
Setup: To attach the P921 filters, align the bayonet connectors on the filters with the corresponding slots on the Portwest P500 Full Face mask or P420, P430, P431 Half Masks. Push the filter in and twist clockwise until it clicks into place, ensuring a secure seal. Always check that the filters are properly seated before use.
Compatibility: These ABEK1 filters are *only* compatible with the Portwest P500 Full Face masks and the P420, P430, P420, P431 Half Masks. They are not interchangeable with other respirator brands or models.
Care: Store filters in their original, sealed packaging in a cool, dry place away from direct sunlight and chemicals. Once removed from packaging and fitted to a mask, the filter's lifespan depends on exposure levels and environmental conditions. Filters should be replaced when breathing becomes difficult, if damaged, or after prolonged use according to manufacturer guidelines (specific lifespan details not provided in product description). Ensure the respirator is cleaned after each use.
