How to Use This Calculator
  1. Enter the room volume (cu ft) (length x width x height) for the work area.
  2. Set the target air changes per hour (ACPH) -- IICRC S520 recommends >=4 ACPH for mold work.
  3. Review required CFM, number of units needed, and daily kWh consumption.
  4. Check filter life (days) to plan filter changeout schedules and consumables budget.
  5. Verify negative pressure is achievable with the selected units before starting containment work.
