# Manrose QF100T 100mm Quiet Bathroom Extractor Fan with Timer

The Manrose QF100T is a 100mm bathroom extractor fan with an adjustable overrun timer, backdraught shutters and wall or ceiling mounting claims. Its listed low-noise and low-power figures make it worth considering where quiet ventilation matters, but the product details give conflicting power and airflow measurements that should be checked before purchase.
