Benefits
Correct humidity preserves acoustics, protects wooden instruments and surfaces, and ensures stable sound quality for performers and audiences.
Protects instruments
Helps prevent the need for frequent retuning and reduces dimensional changes in wood.
Building preservation
Maintains the integrity of natural building materials such as wood and textiles.
Vocal performance
Creates optimal conditions for singers and supports high-quality performances.
Humidification of concert halls and organ chambers
Humidification for concert halls and organs
Concert halls are often historic buildings with many natural materials, such as wood and fabric. If the air is too dry, moisture is drawn from these materials, resulting in structural deterioration that can be costly to remediate and may negatively affect the venue’s acoustic performance.
Large pipe organs are highly susceptible to humidity variations due to their numerous wooden components, such as wind chests, trackers, bellows, and casework. Even minor dimensional changes can lead to air leaks, sticking sliders, and mechanical misalignments. These issues may cause tuning and pitch problems, component failures, disrupted performances, and significant repair costs.
We supply humidification systems to many of the world’s leading music venues and pipe organs, including the Royal Albert Hall, the Sydney Opera House, and the Elbphilharmonie. Yet it’s not only prestigious institutions that benefit—smaller venues such as church halls around the world also rely on our expertise with the same level of care and dedication.

Dehumidifiers for pipe organs, churches and music venues
High air humidity can not only impact the quality of a pipe organ’s performance but also damage its structure and shorten its lifespan. Wooden parts can swell in damp conditions, causing misalignment of moving parts or “cipher” (continuous play). Leather components, such as bellows, gaskets, and valve pouches, can become soft and prone to mould growth over time, weakening their durability.
In very high humidity, cold metal pipes can suffer condensation, which in turn leads to corrosion. Properly maintained, a pipe organ will last for many decades, but correct humidity control is essential to avoid costly restoration.
We support all types of music venues, churches, and concert halls in maintaining the ideal conditions for organs and building interiors. Free expert advice is available for product selection, installation, and service options.

Humidity enhances vocal performance
For singers, a dry environment can negatively impact performance and even affect their health. If the mucous membranes in the throat dry out, singers may experience hoarseness or vocal fatigue. This is especially true under the added heat of stage lighting during the dry winter months.
The ideal humidity for singers is between 40–60% RH, with many experts recommending a tighter range of 45–55% RH. At this level, the vocal cords remain lubricated and hydrated, allowing singers to maintain clarity, range, and control.

Use Cases
Prevent evaporative losses
Organic materials have an internal moisture content and will lose moisture to the atmosphere when exposed to air with low humidity. Humidifiers are used to create an environment with the proper balance between the material’s internal moisture content and the air’s relative humidity.
Managing humidity for long-term preservation
To protect and preserve materials, a stable environment is essential. This includes avoiding extremes of humidity and, more importantly, rapid fluctuations.
Healthy voice with optimal humidity
Optimal humidity protects the voice from strain, hoarseness, and vocal issues. This is an important factor for better health and well-being—for example, in call centers, concert halls, opera houses, or customer service departments, where the voice is under significant strain and the quality of communication is important.
Discover Condair in action
McEwan Hall at the University of Edinburgh
The pipe organ in McEwan Hall is one of the hall’s most distinctive features and historically one of the more unusual organs in Britain. The organ was built in 1897 by the innovative British organ builder and inventor Robert Hope-Jones and refurbished in 2010 by Forth Pipe Organs. Condair resistive steam and evaporative humidifiers are helping maintain the ideal humidity for optimum musical resonance and preservation.
Royal Albert Hall
The Royal Albert Hall is probably the best-known concert building in Great Britain. Around two million guests a year enjoy acoustic cultural delights ranging from rock to classical music. Condair steam humidifiers ensure a perfect humidity in the organ chamber so that wooden parts maintain their integrity and shape, and move over each other perfectly, as they were designed to do.
Christ's Hospital Organ
Condair has supplied a Condair CP3 steam humidifier to humidify the school hall organ at Christ's Hospital School near Horsham, ensuring it resonates correctly and remains in tune whatever the weather. Large pipe organs need to have the humidity maintained within their organ chambers in order to preserve the wooden sound boards and sliders. If the air in the organ chamber becomes dry then it will draw moisture from the surrounding wood causing it to suffer dimensional changes. This can cause the sliders to warp and stick, resulting in an unresponsive instrument. By maintaining 55% relative humidity (%RH), the wood is in equilibrium with the air and it retains its moisture content and shape.
Allianz-Arena, Munich
The Allianz Arena was one of the most controversial construction projects, even prompting a public vote by Munich citizens. It has since become a central landmark in northern Munich and an architectural symbol of the city. Particularly striking is the translucent, diamond-shaped outer shell, which can glow in different colors.
Using projectors and asymmetrical parabolic mirrors developed specifically for the Allianz Arena, the diamonds can be illuminated in different colors depending on the club's colors. The stadium is around 50 meters high, 200 meters long, and can accommodate 66,000 spectators. Condair RS steam humidifiers ensure optimum humidity levels.
