Replace the charcoal/polyester filter in your Foredom® filter hood regularly to keep operating at peak efficiency. Charcoal is ideal for capturing finer particles than polyester alone can. Collect and ship used filters to a refiner to recover and recycle precious metal particles and dust. This set contains five filters.
• Charcoal/polyester filters—filters fine to medium particles, with a 13 Merv rating. The filter will trap and hold 90% or more of 3.0–10 micron particles and 75% of 0.3–1.0 micron particles.
• Insert the filter with charcoal side toward the collection area of the hood.
