【Product Name】 Dyson PH03 WS N Purifier Humidify+Cool Humidifying Air Purifier Genuine Pump Since the shape is the same, it is compatible with PH01 to PH05. Parts are sold separately due to main unit failure. 【Condition】 Disinfected with citric acid in the spring of this year for immediate use. Humidification has not been used after disinfection, but final operation check was performed before listing. (I own multiple units of the same model) Thank you for viewing.
