Size containment air changes and HEPA filtration for mould remediation.
Scrubber count follows from the containment volume and the target air change rate. Negative pressure matters as much as filtration, because it is what stops spores migrating into clean areas during the work. Disturbing mould without containment spreads it far more widely than leaving it alone, which is why the containment sizing comes before any cleaning.
Mold Remediation
Required airflow = containment volume × target air changes per hour
This is a planning estimate only and not a health assessment. Mould exposure can cause serious respiratory illness, and extensive growth or any growth linked to sewage or contaminated water should be assessed by a qualified remediation professional.
