@Gargron@mastodon.social I can recommend the Dyson HP2, or slightly cheaper HP1 which has a few fewer filters and slightly less app features. But both are brilliant at quickly heating rooms and you can pick one up at Argos immediately. Speaking from a very leaky 200+ year old building in Cumbria, with open chimneys and single glazed wooden framed windows. Gets a tad chilly in here!
