Tackling humidity and mould in changing rooms and spa facilities
Warm, humid air is unavoidable in leisure environments. Showers, pools, saunas and damp towels all add moisture to the air. While these features create comfort for guests, they also create ideal conditions for mould and odour to form.
Where humidity becomes a hygiene problem
Changing rooms, washrooms and spa areas often combine heat, moisture and limited ventilation. When the air cannot circulate freely, humidity condenses on walls, ceilings and lockers. This provides a breeding ground for mould spores and bacteria that release persistent musty odours.
Facilities with poor ventilation or sealed windows face the greatest risk, especially during colder months when external airflow is reduced. Even daily cleaning cannot fully prevent this build-up once airborne microbes take hold.
The real impact of mould and odour
Mould is more than a cosmetic issue. It can cause:
• Lingering smells that make a space feel damp and unhygienic.
• Damage to walls, paint and fixtures through gradual moisture exposure.
• Discomfort for staff and customers, particularly those with allergies or asthma.
In high-traffic environments such as gyms, spas and wellness centres, these issues can affect reputation and customer satisfaction as much as visible cleanliness.
Why traditional solutions fall short
Dehumidifiers and extractors help manage moisture, but they do not deal with airborne microbes or the compounds that cause odours. Fragrance dispensers may cover smells for a short time, but they do nothing to prevent recontamination.
Once humidity levels rise, bacteria and mould can reappear within hours. A visible clean does not always mean hygienic air.
How AIRsteril tackles humidity-related odours
AIRsteril technology continuously purifies the air by breaking down bacteria, mould spores and odour-causing compounds. By treating the air itself, it helps:
• Reduce the airborne microbes that contribute to mould growth.
• Keep changing rooms and spa areas fresher between cleaning cycles.
• Limit re-settling of airborne particles on surfaces.
• Support maintenance by reducing the effects of condensation and humidity.
Creating a healthier leisure environment
By controlling the unseen causes of odour and mould, AIRsteril helps maintain a pleasant, hygienic atmosphere even in the most humid environments. Guests notice the difference immediately, and staff benefit from a fresher workspace that stays clean for longer.

"The UK banking centre at Canary Wharf is populated with modern skyscrapers featuring the latest in office building technology. The Credit Suisse UK HeadQuarters allows staff to make the most of windows which has meant that the main building services are sited in the middle of the building. As such with long air ducting, their luxury washrooms struggle to maintain air quality and a clean, fresh smelling work place.
They have installed AIRsteril for odour and infection control in their washrooms. Convinced that the bacteria and viruses that cause infections are killed by AIRsteril, the new offices will feature MF units to ensure staff absenteeism is kept to a minimum."
Marylebone Cricket Club
"On a Test Match day at Lord's there are 25,000 people, mostly males, spending all day watching cricket and drinking. With several visits per person during the day the gents toilets can have up to a 10,000 footfall a day. The staff have had difficulty in clearing the resulting odours. The stainless steel trough urinals in some of the washrooms create added problems.
Just in time for a major Test Match, AIRsteril WRX trial units were installed in two of the major washrooms. After just a few hours, the units had managed to get on top of the smell, then controlled the odours throughout the 5 day match. The facilities staff are very pleased and plan to increase the number of installations before the start of the next cricket season."
