UAE Indoor Air Quality guidelines
HVAC systems are required to be free from visible mold growth and microbiological contamination.
Any detected mold contamination requires immediate corrective action in accordance with IAQ compliance requirements.
Regulations are clear: visible mold and microbial growth in air systems are not acceptable under UAE environmental health standards.
Indoor air must remain within defined VOC limits
- TVOC ≤ 300 µg/m³ (8-hour TWA)
- Formaldehyde (HCHO) ≤ 0.08 ppm (8-hour TWA)
Any exceedance is a compliance failure and requires immediate corrective action: source identification, ventilation correction, and professional HVAC remediation.
VOCs don’t need visible dirt to be dangerous - they can build up silently and circulate through the HVAC system, degrading air quality and increasing health risk.
Suspended particles must remain within regulated limits, including:
- Total Suspended Particles (TSP) ≤ 150 µg/m³ (8-hour average)
- PM10 and fine particles must remain within approved health thresholds
Exceeding these limits constitutes a breach of IAQ compliance requirements and requires immediate corrective action — including filtration inspection, HVAC system cleaning, and airflow correction.
Dust is not just visible dirt. Fine particles circulate continuously through the HVAC system, degrading indoor air quality and increasing respiratory strain, particularly for children, allergy sufferers, and individuals with asthma.
HVAC systems must be free from microbiological contamination. Elevated airborne bacterial levels or contamination within the system constitute a violation of environmental health compliance requirements.
There is zero tolerance for active microbial growth inside air distribution systems. Any confirmed bacterial contamination requires immediate corrective action, including system disinfection and professional remediation.
