Nuaire urges built environment to champion Indoor Air Quality on Clean Air Day 2025

As the UK mark’s Clean Air Day on 19th June 2025, Caerphilly-based ventilation solutions provider Nuaire is calling on specifiers, consultants, and contractors to put indoor air quality (IAQ) at the heart of building design and performance.

Clean Air Day is the UK’s largest campaign dedicated to raising awareness of air pollution and its impacts on health and the environment. Organised by the charity Global Action Plan, this year’s theme encourages individuals and organisations to take practical steps to reduce pollution and protect public health, both inside and outside buildings. Activities range from educational sessions in schools and workplaces to community-wide initiatives that promote greener, cleaner living and working practices.

While the national conversation often focuses on outdoor emissions, Nuaire is taking the opportunity on Clean Air Day to emphasise that clean air doesn’t stop at the front door. With the average person in the UK spending around 90% of their time indoors, the air we breathe inside homes, offices, schools, hospitals and other environments is just as critical to our wellbeing as the air outside.

“Indoor air pollutants are an invisible challenge,” said Meirion Richards, Managing Director at Nuaire. “From carbon dioxide and VOCs [Volatile Organic Compounds] to particulate matter and excess humidity, harmful pollutants can build up, especially in modern well-sealed, energy-efficient buildings. The right ventilation strategy is essential — not only to meet Building Regulations, but to protect occupant health long after the building is handed over.”

On this year’s Clean Air Day, Nuaire is calling for a performance-led approach to ventilation, ensuring that systems are not only compliant with Parts F and L of the Building Regulations but are also designed for real-world effectiveness. This includes adopting technologies such as mechanical ventilation with heat recovery (MVHR), demand-controlled ventilation, and hybrid systems — all tailored to occupancy and usage patterns.

Meirion continued: “Developers, architects, M&E consultants, contractors, and building managers all share responsibility for delivering healthy indoor environments. It’s not enough to specify a system; it must be commissioned properly, maintained over time, and designed with IAQ outcomes in mind.”

With a legacy of innovation dating back to 1966, Nuaire offers a comprehensive range of energy-efficient ventilation solutions across the residential, commercial, and industrial sectors. These systems are designed to reduce indoor pollutants, prevent damp and mould, and provide a consistent supply of fresh, filtered air.

Clean Air Day serves as a timely reminder that improving air quality is a shared responsibility — and that healthier buildings start with healthier air.
