Evaporative Air Cooler and Heater with 3 Speeds and 3 Modes

This Costway evaporative air cooler doubles as a heater, making it a genuine year-round single unit rather than a summer-only buy. As an evaporative cooler it draws warm air through wet pads, so it sips electricity and uses no refrigerant at all – running costs come in at a few pence per hour, far below a compressor air conditioner. Three fan speeds let you dial the breeze from gentle to brisk, while three operating modes adjust output to the room and the weather. Being evaporative, it works best in the UK's drier, hotter spells; honesty matters here – above roughly 60–70% relative humidity the cooling effect tapers off, so it is not a substitute for refrigerated air conditioning on muggy days. In winter the heat setting takes over, so one portable unit covers both seasons. The single-piece, portable design means no window venting, no exhaust hose and no installation – fill the tank, plug in and move it between rooms freely. With refrigerant-free low-energy cooling, multi-season heating and simple controls, it suits anyone wanting flexible comfort without the cost or fuss of fixed air conditioning.
