We combine high-grade testing equipment with eco-friendly treatments to restore air quality, reduce health risks, and give peace of mind to everyone on site.
Air Quality Testing
We assess indoor spaces for key health and safety risks — including carbon dioxide levels, dampness, poor airflow, airborne particles, and temperature imbalances. You’ll receive a clear report with our findings and straightforward advice on what to do next.
Eco-Safe Air Treatment
We use a fast-acting, non-toxic treatment to neutralise airborne bacteria, mould spores, viruses, and odours. It’s alcohol-free, pH neutral, non-flammable, and non-scented — safe for people, equipment, and enclosed spaces. A reliable and environmentally friendly way to improve indoor air quality without harsh chemicals.
Moisture & Ventilation Support
We provide high-quality dehumidifiers to help tackle damp, humidity, and poor ventilation in enclosed or underused areas. Ideal for film sets, pop-up venues, and short-term spaces, this service can be booked on its own or alongside our air quality treatments depending on your needs.
We provide scheduled air quality checks and follow-up treatments for longer-term projects or frequently used spaces. Whether you're running a production, event, or temporary setup, our ongoing service ensures your air stays safe, without disrupting operations. indoor air quality testing watford air testing air purification
