Hi, an occupant in our project building (office) insists on indoor smoking.
He agreed to installing a cabin in his kitchenette (they already smoke there). The cabin is able to comply with LEED requirements (deck-to-deck-partition, 5Pa negative pressure). Additionaly the cabin filters the air through 3 filters:
1. F7
2.HEPA-filter H14 which filters particles down to 0.01µm
3. adsorption filter (activated carbon) removing smells and hazardous gases.
It has been shown that the exhaust air contains less VOCs and hazardous substances from tabaco smoke than required by WHO for indoor air.
Are we allowed to exhaust this thoroughly cleaned air to the outside within the 25ft?
Thank you.

Would the air be exhausted to a location within 25ft of a building opening or air intake? If so, I'm not sure that would be acceptable despite the filtration that you describe. But, it might be possible if you were able to demonstrate that the exhaust air were similar in quality to the ambient outdoor air. Otherwise, the best solution would be to exhaust further than 25ft from the openings/intakes.
