Short answer
Commercial IAQ during restoration means negative air pressure, physical containment, and continuous high-CFM industrial HEPA scrubbing. That keeps mold spores, silica dust, and VOCs out of occupied zones while drying and demolition run.
Dive deep
The deciding controls are containment air-exchange rates and pressure differentials—air should flow into the work zone, not out. On site we verify manometer readings, size ACH to room volume and scrubber CFM, seal HVAC supplies/returns, hold RH under about 50% with LGR/desiccant gear, and clear containment only after particle counts meet criteria.
Air fresheners or disinfectant fogging are not IAQ control. They mask odor and do not remove spores or dust. Real control is HEPA filtration, negative pressure, and moisture removal.
When it applies
- Commercial buildings, schools, medical, and multi-family projects with water mitigation or demolition
- Jobs where secondary mold or dust could reach occupants
When it does not
- Minor residential spot repairs where local containment or HEPA vacuuming is enough
