According to common environmental health findings, indoor air pollution levels are often 2–5 times higher than outdoor levels. This is because indoor environments have more concentrated sources of pollution and less ventilation to disperse them, allowing pollutants to build up over time.
Schools are a clear example of this, as they often experience a continuous build-up of indoor air pollution throughout the day. Classrooms are densely occupied for long periods, and activities such as breathing, movement, cleaning, and the use of materials all contribute to rising levels of carbon dioxide and other pollutants. Because ventilation is not always sufficient to fully refresh the air between lessons, these pollutants can gradually accumulate, particularly in busy or poorly ventilated spaces.
Why Air Quality Matters for Pupils
Asthma affects 1 in 11 children in the UK (NHS) and is the most common chronic disease among children worldwide (WHO). Poor air quality can irritate the airways, worsening symptoms such as coughing and wheezing, while also increasing respiratory sensitivity in children without asthma due to their still-developing lungs.
This can affect pupil comfort, concentration, and overall learning outcomes, which is why indoor air quality is becoming an increasingly important consideration in school design.
Flooring as a Key Part of the Solution
Flooring choice plays an important role in managing indoor air quality, as materials can influence how much dust, dirt, and allergens are retained or reintroduced into the air.
Heckmondwike manufactures carpets using low-VOC materials designed to help trap dust and fine particulates at floor level, preventing them from becoming readily airborne during normal classroom activity.
Unlike hard flooring, where dust and debris can remain on the surface and become easily re-suspended through movement and airflow, carpets act as a passive filtration system. Their fibre structure helps capture and retain particles such as:
- Dust and fine particulate matter
- Pollen and allergens
- Airborne debris
- Dirt tracked in from outside
By holding these particles within the carpet pile, airborne contamination can be reduced, helping to support a more stable and comfortable learning environment.
Maintenance and Long-Term Performance
While carpets contribute to improved particle control, their performance is dependent on effective and regular maintenance. Without appropriate cleaning, trapped dust and allergens can build up over time and may be reintroduced into the air through footfall and daily activity.
Recommended maintenance in school environments includes:
• Daily vacuuming using high-efficiency filtration systems
• Scheduled deep cleaning every 12–18 months
• Prompt spill and stain management
• Planned maintenance programmes to control long-term soil build-up
With the correct maintenance regime in place, carpets continue to effectively capture and retain airborne particles, supporting improved indoor environmental quality throughout their service life.
