Adequate ventilation is critical for our health and well-being, as well as for keeping homes free from harmful issues such as mould and condensation. However intrusive noise concerns can mean that optimal ventilation levels are not achieved as fans may be turned off by tenants.

Yet switching off these extractor fans, which may be located in bathrooms or kitchens, can have dire consequences on both the building itself and the health of the occupants living inside.

As a landlord, this may be of particular concern should a necessary extractor fan be routinely turned off by tenants as it could result in a build-up of condensation and mould, damaging the infrastructure of the property.” This can be costly to rectify, but more importantly, turning off a fan can pose risks to the health and well-being of tenants as mould developing from untreated condensation can lead to serious health problems. Inhaling mould fragments or spores can inflame the airways, causing nasal congestion, wheezing, chest tightness, coughing and throat irritation. Bad ventilation can also have a damaging impact on sleep quality, which in turn can lead to mental health issues.

Fan design to reduce noise

With continuously running fans, it is the pitch of the device that is the main cause of nuisance noise and the core reason why tenants and residents are switching them off. This is especially the case in social housing, where dwellings are often close in proximity to each other, meaning that excess noise is of particular concern.

We have designed our new Unity CV3 fan with this issue in mind, incorporating new features such as innovative aerodynamic propeller design, updated motor electronics and SMART technologies into the device, resulting in a low noise output of 14.5dB(A) - quieter than a whisper.

SMART Technologies

Smart Timing is unlike other fan-timer technologies as it analyses the duration of time that a person is using a bathroom for and overruns for that duration of time. This ensures that if you have a quick trip to the bathroom, the fan does boost for an extended period of time.

Smart Humidity sensing is also a new, innovative feature as it senses man-made spikes in humidity – like taking a shower – to activate the boost. This eliminates boost, when it is a hot and humid day for example, and also reduces energy waste.

The new ‘Do Not Disturb’ feature of the device specifically tackles nuisance noise at night; a time frame can be set to turn off the boost function (so that if you get up in the night, the fan wont boost).
