This Costway evaporative air cooler is a refrigerant-free, windowless alternative to air conditioning that triples as a cooler, humidifier and fan. Because it uses water evaporation rather than a compressor, it needs no installation and no exhaust hose – just add water and the included ice crystal boxes for an extra burst of cool. Running on a mere 60W, it costs barely over 1.5p per hour at 26p/kWh, making it one of the cheapest cooling options to run. At ≤44 dB it is genuinely quiet enough for a bedroom, and the three modes (normal, natural, sleep) plus three fan speeds and a 0-12 hour timer let you set it and forget it overnight. A 2.8L tank gives long sessions between refills, while 90° vertical and 60° horizontal oscillation spread air to every corner. Be aware of the honest limitation of evaporative cooling: it works best in dry heat and underperforms once humidity climbs above roughly 60-70%, so it is a comfort breeze rather than a temperature-slashing AC. The box includes the cooler, two ice crystal boxes, remote and manual. At just 4 kg it lifts easily between rooms.

Description
This Costway evaporative air cooler needs no installation, runs on just 60W and works three ways: as an air cooler (add water and ice), a humidifier (add water) or a regular fan (no water needed). A generous 2.8L tank means long cooling sessions without frequent refilling, and two included ice crystal boxes add an extra burst of cool.
Three modes (normal, natural and sleep) and three fan speeds let you tailor the airflow, while 90° vertical and 60° horizontal oscillation spread cool air to every corner. A remote and 0-12 hour timer add convenience, and it runs quietly at ≤44 dB.

3 Speed Evaporative Air Cooler with Sleep Mode and 3 Wind Mode — FAQs
Do evaporative coolers like this work in the UK?
They work best in dry heat. During the UK's drier, hotter spells this Costway cooler gives a noticeable breeze, but in muggy weather above roughly 60-70% humidity evaporative cooling is less effective.
Can you add ice to this air cooler?
Yes. It comes with two ice crystal boxes you freeze and drop into the tank to boost the cooling effect on warmer days.
How much does the Costway air cooler cost to run?
It uses just 60W, so at around 26p/kWh it costs roughly 1.5p per hour – far cheaper than a compressor-based air conditioner.
Is it quiet enough for a bedroom?
Yes. At ≤44 dB with a dedicated sleep mode and 0-12 hour timer, it is quiet enough to run through the night.
Does it need venting or installation?
No. Unlike a portable air conditioner it has no exhaust hose and needs no installation – just fill the 2.8L tank and switch it on.
