Hi my dyson HP07 seems having issue to stabilise the temperature in my 6 month son room .. i set it as 24 in my son room.. but the room is constantly at 22 and the machine stay in stand by, doesn't heat up the room and had cold air coming out?
Is it reccomended to keep HP07 on all night and what is the best option?
When the machine is in stand by does it purify the air?
