Engineered for professionals in high-risk environments, this filter provides definitive protection against demanding airborne threats. Its core strength is an advanced dual-layer filtration system. The primary layer features a medical-grade electrostatic microfiber medium, validated to capture 99.97% of particles at 0.3 microns and larger-including fine dust, metal fumes, and mold spores. A secondary, pleated chemical layer effectively adsorbs hazardous gases and VOCs like benzene.

This comprehensive barrier delivers an Assigned Protection Factor (APF) exceeding 1,000. Built for sustained performance, its high-flow design maintains breathing resistance below 45 Pa to prevent fatigue. Housed in durable, chemical-resistant ABS with a secure bayonet mount, it ensures a reliable, airtight seal for long-lasting safety and efficiency.

Independent third-party testing underscores its long-term reliability. The filter maintains over 95% of its original filtration efficiency even after the equivalent of 1,000 service hours, far outlasting conventional options. Each unit undergoes rigorous individual leak testing at 1,000 Pa pressure, ensuring inward leakage remains below 0.05%, a performance that significantly exceeds the requirements of the EN 143 standard. With a shelf life of five years, the Air Purifying Respirator Filter represents a cost-effective, high-performance solution, offering professionals not just protection, but the confidence of proven and enduring filtration efficiency in the most challenging workplaces.

What is the filtration efficiency of this air purifying respirator filter?

The filter is equipped with an advanced dual-layer filtration system. Its primary medical-grade electrostatic microfiber layer is validated to capture 99.97% of particles at 0.3 microns and larger, including fine dust, metal fumes, and mold spores. Additionally, it maintains over 95% of its original filtration efficiency even after the equivalent of 1,000 service hours, far outperforming conventional filters.

What does the dual-layer filtration system consist of, and what are their respective functions?

The dual-layer filtration system is composed of two functional layers: ① Primary layer: A medical-grade electrostatic microfiber medium, mainly responsible for capturing particulate matter (0.3 microns and above), such as fine dust, metal fumes, and mold spores. ② Secondary layer: A pleated chemical layer, which effectively adsorbs hazardous gases and volatile organic compounds (VOCs) like benzene, forming a comprehensive protective barrier.

What is the Assigned Protection Factor (APF) of this filter, and what does it mean for professional use?

The filter has an Assigned Protection Factor (APF) exceeding 1,000. This means that in high-risk environments, the filter can reduce the concentration of harmful airborne substances inhaled by professionals to less than 1/1000 of the ambient concentration, providing definitive and reliable protection for workers in demanding working conditions.

What is the breathing resistance of the filter, and will it cause fatigue during long-term use?

The filter adopts a high-flow design, which maintains breathing resistance below 45 Pa. This low-resistance design effectively prevents worker fatigue even during long-term use, ensuring comfort while maintaining high filtration efficiency, making it suitable for professionals who need to wear respirators for extended periods.

What materials are used in the filter housing, and what are their advantages?

The filter is housed in durable, chemical-resistant ABS material and is equipped with a secure bayonet mount. The ABS housing has excellent chemical resistance and durability, which can withstand harsh industrial environments; the bayonet mount ensures a reliable, airtight seal, avoiding air leakage and ensuring the safety and efficiency of the filter during long-term use.
