The basic principle
evaLIGHT is a portable personal device which not only chills but also humidifies and purifies the air around you. The working principle is very simple: you need to fill up the water tank and plug evaLIGHT in. Within 5-10 minutes the evaLIGHT cartridge absorbs a huge amount of water. The water then spreads evenly on the surface of the cooling pads. When the air goes through the pads, the water evaporates, which makes the air cool down while getting saturated with water. The built-in fan helps the cool air spread around the area of 45 ft² (3-4 m²) around you. The power control enables you to adjust the cooling effect, creating the most comfortable thermal conditions for you.
How does it work?
evaLIGHT is easy to operate: simply fill the removable water tank and connect evaLIGHT to a power supply. Within 5-10 minutes the evaLIGHT cartridge absorbs a huge amount of water. The water then spreads evenly on the surface of the cooling pads. When the air blows through the pads, the water evaporates, which makes the air cool down while saturating it with water. There's no heat exhaust as result of the evaporation. The built-in fan helps the cool air spread over an area of 3-4 m² around you. The power control enables you to adjust the air flow, creating most comfortable conditions for you.
The evaLIGHT evaporative cartridge needs to be replaced approximately once in 6 months. Poor air or water quality may affect the cartridge lifecycle duration.
- What does the cooling degree depend on?
evaLIGHT is based on natural water evaporation technology, which takes in hot, dry air and makes it cool and moist. Evaporative air conditioners perform best in drier environments. It is normally dryer indoors than outdoors, and the actual temperature decrease depends on the air's humidity and temperature. The tables below show you evaLIGHT performance for different air conditions.
- Outgoing air temperature drop with various conditions
- How much noise does evaLIGHT make?
evaLIGHT is no louder than the cooling fan of your computer! The noise level depends on the intensity level you set yourself. The normal noise level is 28-35 dB on an average fan speed.
- Does evaLIGHT work without a power supply?
evaLIGHT should be plugged into a power supply. But it doesn’t have to be a power socket. You can plug evaLIGHT into a power bank, USB port of your car or laptop, or even a solar battery. The only condition is that the power supply must have the output of 5V and 2A.
- Additional Cartridge
The evaLIGHT evaporative cartridge needs to be replaced approximately once in 6 months. Poor air or water quality may affect the cartridge lifecycle duration.
