A real air freshener. Most air coolers are at 450 m3/h and this one is at 3000. This should be the standard to have a visible result. It effectively cooled a large room whereas with my old K this was not the case and what's more the pump quickly broke down. It's really well made. On the top you have the ice block compartment where the water will be sucked from the bottom to the top with a small filter which filters the water and believe me, fortunately it is there, this prevents impurities and insects dead does not clog your machine. On the side there is the tank where you put the water, I add ice cubes. This device also has a thermometer showing you the temperature of the air sent. Please, when you activate the water, do not close the room, leave a door open otherwise the water will stagnate in the air and it will give the same effect as after a heavy rain in summer, i.e. an air heavy. The device is great, just be careful not to lock it up like said before. The plastics seem cheap to me but the device itself is killer if you follow my instructions. Obviously it will be necessary if it runs all day remember to add water often and switch with ice packs and ice cubes. Finally, once a week, empty the drain with the drain located behind and not below like other brands. Various people in my family have been won over by this product and want to purchase it. I hope more batches arrive.
