1. What is salon ventilation & air quality?
Salon air quality directly affects both client comfort and stylist long-term health[1]. Chemical vapours from colour processing, keratin treatments, nail products, and aerosol sprays accumulate in poorly ventilated spaces. In any country, occupational health regulations set exposure limits for formaldehyde, ammonia, and volatile organic compounds[2].
2. The minimum you must do
Daily salon ventilation checklist
- HVAC system running during operating hours
- Chemical mixing area has local exhaust ventilation
- CO₂ monitor reads below 1,000 ppm
- Air filters cleaned/replaced per schedule
- Windows opened if mechanical ventilation insufficient
- Ventilation log updated with today’s reading
- No blocked vents or obstructed airflow paths
3. Key numbers to remember
| Indicator | Baseline | Target | Time | Measurement |
|---|
| CO₂ level during services | Unknown | <1,000 ppm | 1 week | CO₂ monitor log |
| Air changes per hour (chemical area) | Unknown | ≥10 ACH | 1 month | Engineering assessment |
| Filter replacement compliance | Variable | 100% per schedule | 1 month | Maintenance log |
| Staff respiratory complaints | Unknown | 0/quarter | 3 months | Health questionnaire |
| Ventilation system downtime | Unknown | <2 hours/month | 1 month | Maintenance log |

🐥
Piyo: Poppo, how do I know if my salon's ventilation is adequate?
🦉
Poppo: Measure CO₂ with a monitor — they cost about £30. If the reading goes above 1,000 ppm during service hours, your ventilation is insufficient. For chemical services like colour or keratin, you need local exhaust ventilation or at least 10 air changes per hour in the mixing area.
🐥
Piyo: Opening a window isn't enough?
🦉
Poppo: In summer with a breeze, maybe. In winter, no. Cross-ventilation through windows rarely achieves the air exchange rate needed to clear formaldehyde or ammonia vapour below occupational exposure limits. Mechanical ventilation is the reliable answer.
🐮
Mou: Strong, kind, beautiful — the air your stylists breathe every day determines their long-term health.
