FAO BRB . Have a look at Dyson's website , this seems new . https://www.dyson.co.uk/purifiers/dyson-pure-cool-summer.html
The portable air con units are pretty **** in my experience, if you really want air con get a permanent unit fitted. You can get a permanent unit suitable for a living room for less than £500.
Stop ****ing about @brb..this little unit would do the job, or a few quid more for a bigger one https://www.saturnsales.co.uk/Samsung-Boracay-2.5kw-Heat-Pump.html
