A: No, the Airvent External Plug-go Run-On-Timer does not require a separate power supply or professional electrician for installation.

A: Using a run-on-timer with your bathroom exhaust fan is one of the most effective strategies for mould prevention. After you finish showering, the air remains humid for several minutes. The Airvent Run-On-Timer keeps the fan running for your chosen duration (1–60 minutes) after the light is switched off, extracting this residual moisture before it settles on walls, ceilings, and grout. This dramatically reduces the risk of mould and mildew growth, protects paintwork and fixtures, and promotes healthier indoor air quality throughout your home.

Always check your specific Airvent fan model's specifications to confirm compatibility before purchasing. The plug-go design makes it easy to connect without hardwiring or electrical modifications.
