<p>An air treatment module 112 comprising a treatment chamber having an air inlet and an air outlet is described. The treatment chamber further having at least one UV radiation source 128 so that air is exposed to UV radiation. The treatment chamber also has a support structure 132 where, part of the surface of the support structure has a photo catalytic surface. The photocatalytic surface is located so that UV radiation irradiates the support structure in use. The support structure is also configured to deflect air as it passes through the treatment chamber. The photocatalyst used may be titanium dioxide and air treatment module(s) may be flitted into air purifying units.</p> |
