Frequently Asked Questions
Which is safer — ducted or ductless?
Ducted hoods provide broader protection because they remove all vapors from the building. Ductless hoods are safe for their rated chemicals when filters are properly maintained. The ‘safer’ choice depends on your chemical list. If you use a wide variety of chemicals or work with unknowns, ducted is the safer choice.
Can I replace a ducted hood with a ductless one?
In some cases, yes — if the chemicals you use are compatible with available filters. This can save significantly on HVAC costs. Labs USA evaluates your chemical inventory to determine if ductless is appropriate before making a recommendation.
