The ZENET ZET-483 is an air cooler with ice packs and a 3-litre water tank. In other words, it is an evaporative cooler, not an air conditioner with a compressor. A fan draws in warm room air and pushes it through a wet evaporative pad. As the water evaporates, the air leaving the unit is noticeably cooler and slightly more humid. The four ice packs that come with it also chill the water in the tank.
The ZET-483 needs no exhaust hose to a window: fill it with water, add the ice packs and switch it on. It uses 65 W. With the remote control you choose one of three speeds, sleep mode or the timer. Worth knowing before you buy: an air cooler does not cool down a whole home the way an air conditioner does. It gives you a stream of fresh air exactly where you sit, work or sleep.

Who it is for
For anyone who cannot or does not want to set up an air conditioner with a hose in a rented flat, a bedroom or a home office, and who would like a refreshing stream of air at the desk, on the sofa or by the bed on hot days.
The ZET-483 is less suitable if you need to bring a whole room down by several degrees during a heatwave. For that you need an air conditioner with a compressor and an exhaust hose. It also works less well in very humid, poorly ventilated rooms, because the air there can hardly take up any more moisture.
Portable air conditioner without a hose? How an air cooler works
Many people search for an “air conditioner without a hose”. An air conditioner removes heat from the air through a refrigerant circuit and has to release that heat outdoors through a hose. An air cooler like the ZET-483 has no refrigerant and uses evaporative cooling instead: water from the tank wets the pad, the fan blows room air through it, and the water absorbs heat as it evaporates. That is why the unit needs no hose. It works best when the airflow is aimed straight at you and a door or window is slightly open, so that humid air can escape.
Getting started with the ice packs:
- Fill the ice packs with water (without spilling any) and put them in the freezer for about 2 hours.
- Fill the water tank and place 2 ice packs in it. Keep the other 2 in the freezer as spares.
- Switch the unit on and choose a speed. For cooler air over a longer time, swap the ice packs every 5–7 hours.

Frequently asked questions
Is the ZET-483 an air conditioner?
No. The ZET-483 is an air cooler (evaporative cooler) with no compressor, no refrigerant and no exhaust hose. It cools the air that flows through the wet pad. The temperature of the room as a whole drops far less than it would with an air conditioner. What you mainly feel is the cool airflow close to you.
How much electricity does the air cooler use?
Example: 65 W × 8 hours = 520 Wh = 0.52 kWh per day. Multiply this by your price per kWh, which you will find on your electricity bill.
How often do I need to refill the water and swap the ice packs?
The tank holds 3 litres. How long one fill lasts depends on the speed, the temperature and the humidity. Swap the ice packs for the spare ones from the freezer every 5–7 hours.
How do I clean the air cooler?
Empty and rinse the water tank regularly so that no water is left standing in it. Pull out the air filter and clean it. Before a longer break, let the tank and the pad dry completely.
