Action's Nedis evaporative air cooler is a budget-friendly device priced at just €39.95, designed to help households cope with heat waves without relying on energy-hungry air conditioning. As temperatures rise again, many are looking for ways to stay cool while keeping electricity bills in check.
This portable cooler offers a middle ground between a simple fan and a full split air conditioner, using evaporative cooling technology to lower the temperature of the air it blows out.
What Is the Nedis Evaporative Air Cooler?
The Nedis air cooler is a compact, portable appliance that uses the natural principle of evaporative cooling. Unlike traditional portable air conditioners that require installation, a window hose, and a high-consumption compressor, this model simply needs water.

You fill its built-in tank with water—and can add ice blocks to enhance the effect. A wet filter absorbs hot, dry air from the room and passes it through a moistened pad. As the water evaporates, the air temperature drops, releasing a cooler, more humid breeze than a conventional fan.
How Does Evaporative Cooling Work?
Evaporative cooling is a well-known physical process: when water evaporates, it absorbs heat from the surrounding air, lowering the temperature. The Nedis cooler harnesses this by drawing warm air through a water-saturated filter.
The result is a stream of air that feels noticeably fresher than the ambient air, especially in dry climates. This makes it particularly effective in regions with low humidity, where the air can absorb more moisture.
Key Features and Benefits

Who Should Consider This Cooler?
The Nedis evaporative cooler is ideal for people living in dry climates who want a low-cost, low-energy way to stay comfortable during heat waves. It's also a good option for those who cannot install a split AC or want to avoid high electricity bills.

However, it may not be suitable for humid areas, as evaporative cooling is less effective when the air is already moist. In such cases, a traditional fan or a dehumidifier might be a better choice.

FAQ
How does an evaporative air cooler differ from a regular fan?
A regular fan only circulates air, which can feel refreshing but doesn't lower the temperature. An evaporative cooler adds moisture to the air, which cools it down, providing a more noticeable cooling effect in dry conditions.
Can I use the Nedis cooler in any room?
Yes, it's portable and can be moved between rooms. However, it works best in well-ventilated spaces where dry air can be drawn in. Avoid using it in closed, humid rooms.
Does the Nedis cooler consume a lot of electricity?
No, it uses very little energy compared to air conditioning. It typically consumes less than 100 watts, which is a fraction of what a split AC uses.
Is it effective during a heat wave?
It can provide relief, especially in dry climates. For maximum effect, use it with ice blocks and ensure good airflow. In high humidity, its cooling power is reduced.
