Every breath taken indoors tells a story about the air around us, its freshness, warmth, and the unseen particles it carries. Each year on World Ventilation Day<\/strong><\/a> (8th November 2025), that story becomes more relevant, as this is the time of the year when we typically see the arrival of colder\/wetter weather and office windows stay closed.\u00a0<\/p>\n\n\n\n

Restricting airflow through keeping windows and doors closed can lead to the air circulating through our buildings growing heavy with dust, bacteria and carbon dioxide. Whereas, well-maintained ventilation keeps air fresh, minds clear, and workplaces more productive.<\/p>\n\n\n\n

The quality of indoor air shapes how people feel, think and perform. On 8 November, World Ventilation Day invites every organisation to take a closer look at their indoor environment and the systems that keep it healthy.<\/p>\n\n\n\n

The winter challenge for workplace air<\/strong><\/h2>\n\n\n\n

When heating systems start up and doors remain closed, airflow slows. Pollutants from cleaning products, printers and kitchens gather in the air, while moisture and carbon dioxide increase. Over time, this can make people feel sluggish, uncomfortable, or unwell.<\/p>\n\n\n\n

Pollution levels indoors can reach up to five times higher than outdoors<\/a>. Research shows that we spend around 87% of our lives indoors<\/a>, much of it at work. That makes how to improve indoor air quality<\/strong> an essential consideration for every employer. Evidence<\/a> links poor ventilation to respiratory and cardiovascular problems that can quietly impact productivity and wellbeing.<\/p>\n\n\n\n

Why ventilation and duct hygiene matters<\/strong><\/h2>\n\n\n\n

Air systems are designed to circulate and filter the air we breathe. When ductwork collects dust, grease or moisture, it can send contaminants back into the workspace. Put simply, efficiency falls, costs rise, and air cleanliness<\/strong> declines. Rentokil Specialist Hygiene<\/a> provides air duct and ventilation cleaning services which includes Preferred Vacuum Testing (PVT) to assess how clean your ventilation system is by measuring the levels of dust and debris deposits. Helping to restore airflow, improve efficiency, and ensure businesses comply with HSE ventilation standards<\/a> under the Health and Safety at Work Act 1974<\/a>.<\/p>\n\n\n\n
