The Costway 3-in-1 evaporative air cooler combines cooling, humidifying and fan functions, drawing room air through water-chilled pads to deliver a cool, refreshing breeze for a fraction of the energy of a compressor. The headline figure is its running cost: at just 65W it draws about 0.065kW, costing under 2p an hour at around 26p/kWh — dramatically cheaper than any air conditioner, and refrigerant-free so there's no hose and no installation. A large 20L water tank means far fewer refills than smaller coolers, and two included ice blocks drop the output temperature further on hot days. You get 3 modes and 4 speed settings (up to a 10m/s wind speed), all controlled by the included remote, plus a 7.5-hour timer. It runs at ≤60dB. An honest note on evaporative cooling: it works by adding moisture to the air, so it's most effective in dry heat and underperforms once humidity climbs above about 60-70% — it lowers temperature and circulates air rather than refrigerating a room like an AC. At 7kg and built from ABS, measuring 37 x 32 x 73cm. Supplied with the air cooler, 2 ice blocks, remote control and instruction manual. Please note this item is currently out of stock.

Description

This portable evaporative air cooler combines cooling, humidifying and fan functions in one stylish unit, using cold water to chill and circulate air around the room. It offers 3 modes and 4 speed settings for the right airflow.

A large 20L water tank means fewer refills, and the included remote controls every function from across the room. The fan runs quietly for steady, consistent airflow, and a 7.5-hour timer gives you control over runtime.

3-in-1 Evaporative Air Cooler and Humidifier with Remote Control — FAQs

How much does the Costway evaporative air cooler cost to run?

At just 65W it costs under 2p an hour at around 26p/kWh — a tiny fraction of an air conditioner's running cost, with no refrigerant and no installation needed.

Do evaporative coolers work in humid weather?

They work best in dry heat. Because evaporative cooling adds moisture to the air, performance drops once humidity rises above about 60-70%. It cools and circulates air rather than refrigerating a room like an AC.

Can you add ice to this air cooler?

Yes. Two ice blocks are included to drop the output temperature further on hot days, and the 20L tank means fewer refills than smaller coolers.

What's the difference between this and an air conditioner?

An air cooler uses water evaporation to cool and humidify air at very low power and needs no hose, whereas an air conditioner refrigerates and must vent heat outside. This cooler is cheaper to run but won't chill a room as deeply.

How is it controlled and what's in the box?

It has 3 modes, 4 speeds, a 7.5-hour timer and an included remote, running at ≤60dB. The box contains the cooler, 2 ice blocks, remote control and manual.
