Ozone Generator Calculator
Determine precise run times for shock treatments and calculate safe re-entry wait times based on room size and generator output.
CRITICAL SAFETY WARNING
Ozone is a toxic gas. NEVER operate an ozone generator in an occupied space (people, pets, or plants). Ventilate the area thoroughly before re-entering. High concentrations can damage lungs and degrade materials like rubber and certain plastics.

2 Treatment Scenario
Select the intensity based on the problem. Higher contamination requires higher PPM.
3 Generator Specs
Typical commercial units are 5,000 - 20,000 mg/hr.
Estimated Run Time
Safe Re-Entry Calculator
Ozone decays naturally back into oxygen. The half-life is typically 30 minutes. To reach safe OSHA levels (0.1 PPM), you should wait:
*Assumes 30-minute half-life. Ventilation (open windows) significantly speeds this up. Always smell-check cautiously.
How to Perform a Shock Treatment
Measure Your Space
Accurately measure the length, width, and ceiling height of the room. Ozone fills volume, not just area, so ceiling height matters for concentration.
Select Treatment Level
Choose the intensity based on the problem. Light odors like stale cooking need less ozone (3-5 PPM) than deep-set issues like mold or smoke (20+ PPM).
Set Generator Output
Input your ozone generator's output rating (mg/hr). This is usually found on the back sticker or manual. Higher output equals shorter run times.
Execute Safely
Remove all people, pets, and plants. Seal the room. Set the timer and leave immediately. Wait the full re-entry time before returning to open windows.
