1. An air treatment apparatus comprising:
an air flow generator that is arranged to generate an air flow;
a moisture source that is arranged to introduce water vapour into the air flow;
a body that in use surrounds both the air flow generator and the moisture source, the body being arranged to support the moisture source;
a water supply system that is arranged to provide water to the moisture source, the water supply system comprising a water tank assembly that is separable from the body, the water tank assembly comprising:
a water tank, and
a tank-to-body connector that is disposed on the water tank assembly and that is arranged to separably connect to a corresponding body-to-tank connector provided on the body and through which water is conveyed from the water tank to the body;
an interface sealing element that is arranged to form a seal between the water tank assembly and the body that prevents leakage of air into the body;
an air supply feed that is arranged to convey air from within the body of the air treatment apparatus into the water tank assembly; and
one or more air filter assemblies that are located upstream of both the moisture source and the air supply feed.
