The Weller FT91000042 Zero Smog Filter Set with 10 Pre-Filters is a high-efficiency, multi-stage filtration system engineered to deliver advanced air purification for critical soldering and assembly environments. Designed as an upgrade over standard filters, this set combines superior particle and gas-phase filtration for enhanced performance and reliability. The Weller FT91000042 Zero Smog Filter Set with 10 Pre-Filters includes a Main Filter featuring a HEPA Class H13 particle filter that captures 99.95% of fine particulates such as solder fumes, dust, and microscopic debris. It also contains a dual-layer wide-band gas filtration media composed of 50% activated carbon and 50% potassium permanganate (KMnO₄), providing excellent adsorption and neutralization of harmful vapors, volatile organic compounds (VOCs), and chemical gases.

Complementing the main filter is a high-capacity F7 Class Pre-Filter Mat, which provides early-stage particulate filtration. This pre-filter traps larger debris and particulates, significantly extending the lifespan of the main filter components and maintaining optimal airflow performance.

Compatible with Weller Zero Smog EL, TL, and 4V filtration units, this filter set enhances the overall efficiency, longevity, and air quality control of your fume extraction system. Its quick and tool-free installation minimizes downtime and simplifies maintenance for high-throughput production environments.

Ideal for electronics manufacturing, soldering workstations, precision labs, and cleanroom applications, the Weller FT91000042 Zero Smog Filter Set with 10 Pre-Filters ensures maximum fume capture, protects sensitive equipment, and supports operator safety. It’s the perfect solution for facilities demanding high-performance air purification and regulatory compliance in static-sensitive, high-precision environments.
