Our pick: the Dyson Purifier Cool PC1 Powerful Cooling Purifier — the best Fans & Air Conditioning we tested, from £449.99.
UK summers rarely justify fitted air conditioning, which is why portable AC units and air purifying fans have become popular for the few weeks a year homes really need cooling. We compared BTU cooling power, noise and how easy each unit is to vent through a window.

FAQ
What BTU do I need to cool a UK bedroom?+
A 9,000 BTU unit is generally enough for a single or double bedroom up to around 20 square metres. Larger open-plan living rooms, or rooms with lots of south-facing glass, are better served by a 10,000 BTU or higher unit.
Do portable air conditioners need to be vented outside?+
Yes, single-hose portable air conditioners need their exhaust hose run through a window or wall vent kit to expel warm air outside, which is included with most models. Bladeless fans like the Dyson Purifier Cool do not need venting since they only move and filter air rather than actively cooling it.
