The Pure Hot + Cool does all of the above but also acts as an air purifier. It has a HEPA filter, which removes 99.97% of particles that are larger than 0.3 microns from the air. (For reference, a human hair is approximately 75 microns wide.) This makes it a great purchase for allergy and hayfever sufferers.  

At the moment, Appliances Direct is selling the Pure Hot + Cool for £399.98. We reviewed it, loved it and gave it 4.5 out of 5 stars. It usually retails for a very serious £549 but Appliances Direct is currently selling it with a £150 discount. Buy it here
