Product Overview
The P971 ABEK1P3 Combination Filter is a sophisticated piece of respiratory protection designed for professionals operating in environments where multiple hazards coexist. This specific filter is engineered to defend against a wide array of threats, including organic and inorganic acid gases, vapours, sulphur dioxide, ammonia, and its various derivatives. By combining gas and particle filtration into a single unit, it provides a streamlined solution for complex safety requirements, ensuring that the wearer is shielded from both chemical vapours and harmful micro-organisms.
Key Features
- Comprehensive ABEK1 Protection: This filter is specifically rated to protect against organic and inorganic acid gases, sulphur dioxide, and ammonia, offering peace of mind in volatile chemical environments.
- Class 3 Particle Filtration: Rated as a Class 3 filter for particles, it provides the highest level of protection against toxic dust, fumes, and biological agents.
- Secure Bayonet Connection: The specialized Portwest bayonet system allows for a swift and highly secure attachment to the mask, reducing the risk of improper fitment.
- Multi-Mask Compatibility: These filters are designed for seamless integration with a variety of hardware, including the P420, P430, P421, and P431 half masks, as well as the P500 full-face mask.
- Pack of Four: Supplied in a convenient pack of four, ensuring that you have replacements readily available to maintain continuous protection on the job.
Design & Performance
Manufactured in Italy, the design of the P971 focuses on balancing high-level filtration with user comfort. Despite its complex internal structure—housing both chemical adsorbents and high-efficiency particulate filters—the unit remains manageable in size and weight. The combination of Class 1 gas filtration and Class 3 particle filtration means it is highly effective against solvents and toxic particles without being overly restrictive to the wearer's breathing.
The bayonet connection is a standout performance feature. Unlike threaded filters which can sometimes be cross-threaded in haste, the bayonet system provides tactile feedback to ensure the filter is locked correctly in place. This is essential for maintaining the integrity of the respiratory seal during movement or intense physical activity.
Why No Customisation?
This item is a critical piece of Personal Protective Equipment (PPE) and is sold without customisation to ensure its safety certifications remain valid. Applying inks, heat-seals, or embroidery to respiratory filters could potentially compromise the structural integrity of the casing or block the airflow pathways. Furthermore, it is vital that all safety markings and classification codes remain clearly visible for inspection and compliance purposes.
Use Cases
The P971 is an essential choice for those working in chemical manufacturing, laboratory settings, or industrial cleaning where ammonia and acid gases are present. It is also highly suitable for agricultural applications involving the handling of certain fertilisers or pesticides, and for waste management professionals who may encounter a variety of toxic vapours and airborne micro-organisms.

Practical Advice
Before use, always check that the filters are compatible with your specific mask model. Ensure that the bayonet connection is fully engaged and perform a negative pressure fit check by covering the filters with your hands and inhaling slightly; the mask should collapse slightly toward your face, indicating a proper seal. If you detect the smell or taste of a contaminant, or if breathing becomes noticeably difficult, leave the hazardous area immediately and replace the filters.
Caring for your product
To maintain the performance of your combination filters, it is vital to store them correctly when not in use. They should be kept in their original packaging or a sealed container in a cool, dry environment. Exposure to moisture or ambient air will eventually exhaust the active carbon inside the filter, even when it is not being worn, which will significantly reduce its protective lifespan.
Never attempt to clean these filters with water or compressed air. Doing so will destroy the delicate internal structure of the particle filter and potentially cause the chemical adsorbent to clump, rendering the unit useless. If the exterior becomes soiled, a light wipe with a dry cloth is sufficient, but any filter that has been dropped or shows signs of casing damage should be discarded and replaced immediately to ensure continued safety.
