CLEANING YOUR MINI-WRIGHT PEAK FLOW METER
This Peak Flow Meter does not require maintenance (other than cleaning) or calibration for the three years following its first use.
At the end of the three years, it should be replaced. When not in use, this device should be kept in a clean, dry area away from any hazardous substances. It is important to keep your Peak Flow Meter clean when in use. It should be cleaned at least once every six months and thoroughly if it has not been used for some time. The mouthpiece is detachable and should be kept clean using proprietary disinfectant solution such as Dettol. Fungal growths may occur if the instrument has not been cleaned for some time.
