Clean Air Starts Indoors: Why Ventilation Matters More Than Ever

Clean Air Day, the UK’s largest campaign on air pollution, is more than just a date on the calendar - it’s a call to action. While it’s easy to associate air quality with traffic and chimneys, one of the most overlooked spaces we can control is the one where we spend most of our time: indoors.
We’re using Clean Air Day to spotlight the critical role that clean ventilation plays in protecting health and promoting productivity.
The invisible threat in our buildings
Indoor air can be significantly more polluted than outdoor air, and the primary culprit is often hidden in plain sight: your ductwork. Over time, dust, debris, and contaminants accumulate in ventilation systems. This not only compromises air quality but also reduces airflow and puts additional strain on HVAC systems - leading to higher energy costs, reduced efficiency, and even health risks for building occupants.
Why regular duct cleaning matters
Regular cleaning is crucial not only for ensuring that the system operates efficiently but also for maintaining a healthy, comfortable environment. When ductwork is neglected, it can circulate allergens like dust, pollen, and mould throughout the building. Clean systems, on the other hand, help everyone breathe easier and think more clearly.
The tangible benefits of clean ductwork
There are real, measurable benefits to routine ductwork hygiene:
- Enhanced air quality – Contaminants like dust, pollen, and mould are removed before they can affect the air you breathe.
- Improved efficiency – Blockages are cleared, preventing your HVAC system from overworking and using excess energy.
- Prolonged system lifespan – Clean ducts reduce wear and tear, helping systems last longer.
- Compliance with industry standards – Keeping your ductwork clean supports compliance with BS EN 15780 and TR/19, both referenced by ADCAS.
Working together for cleaner air
We provide the expertise to assess, clean, and maintain your systems to the highest standards. From thorough inspections to deep cleans and smart ventilation planning, our solutions are designed to improve both air quality and operational performance.
Take action where it matters most
Improving indoor air doesn’t require grand gestures. Even simple changes - like encouraging employees to cycle to work, monitoring air quality with sensors, or opening windows more regularly - can have an impact. But for long-term, systemic improvement, ductwork hygiene is a powerful place to start.
Clean Air Day is about more than raising awareness - it’s about meaningful action. Clean air isn’t just something we wish for outdoors. It’s something we must build and maintain indoors.
At Vent, we’re committed to helping businesses create healthier environments from the inside out. Because when clean air starts indoors, everyone breathes better.
