Fume Extractor filters require routine cleaning and replacement, dependent on use and materials cut.
Generally, fume extractor suction will diminish and odors will be detected as filters clog.
Never use a fume extractor without all filters in place.
Maintenance guidelines:
Pre-Filters:
Clean often. Use a shop vacuum to clean as debris builds. Check weekly, especially if cutting a lot
of wood. When accumulated debris remains over 70% after cleaning, replace Pre-Filter.
HEPA Filters:
Clean immediately when suction is reduced. Use a shop vacuum to clean accumulated dust.
When cleaning does not return optimal suction power, replace HEPA Filter.
Activated Carbon Filters:
Clean when odors are detected or suction is reduced. Gently shake excess dust
and debris from the carbon filter and follow with a shop vacuum. When cleaning no longer eliminates
detectable odors, replace Activated Carbon Filters
