.   COOLING TECHNOLOGY The beauty of the WINTER-i air cooler is that it generates a steady stream of cold air through evaporation which unlike conventional air conditioners doesnt require the need for a window vent kit or any permanent installation. It works by pulling warm air into the back of the machine through the iPure 5 stage filtration system. The air is then passed through an enhanced honeycomb filter which is wet with water from the tank. The water evaporates and is pushed out of the front of the machine by a fan to create a soothing cool breeze. This also conditions the air with more moisture for added comfort. EASY TO USE The WINTER-i is incredibly easy to use. All you have to do is fill the large 56 litre water tank with water or if you want an even cooler breeze you can fill the tank with ice. Once you have filled the tank all you have to do is turn the machine on choose which of the 3 fan speeds you want the machine to run using and the cooler will deliver an even level of cooling.   MULTI-STAGE AIR PURIFICATIONAs well as combating dry air that can have a negative effect on those with allergies this air cooler features an advanced 4 stage air purification system to ensure you breathe clean healthy air regardless of the weather. The 4 filters are designed to remove microscopic allergens such as dust mites pollen mold and bacteria that may cause people sleeping problems and breathing difficulties. ANTIBACTERIAL FILTER Destroys harmful bacteria and micro-organisms CARBON FILTER Eliminates unpleasant odours like cigarette smoke PM2.5 WASH FILTER Removes impurities in the water from passing through the honeycomb pads. TIO2 CATALYTIC FILTER Removes any harmful VOCs    . Why is this cooler right for you? .

WINTER-i. is an evaporative air cooler cooling the air by means of evaporation. When water evaporates into the air the result is a mixture of air and water molecules. This chemical change requires heat which is taken from the water molecules resulting in a spot cooling effect the temperature drop. The air is passed through a special honeycomb cooling pad which expands the evaporation surface and improves the cooling effect while doubling as an air filter. The evaporative coolers must be used in rooms or spaces with good ventilation otherwise the room will get saturated with humidity and the effect of cooling will stop.Evaporative cooling occurs to every one of us perspiration is the way our body reduces its temperature by evaporation when we are too hot..
