This air purifier is not only really good at cleaning the air and removing any smells, but also it is really quiet and doesn’t require you to constantly change the filters and pay tens of dollars for it, I would say it is the best cheap air purifier.
Thanks to its unique technology, this device just requires you to put a certain amount of water in it, occasionally clean the filter with water and that’s it.
It has 3 modes, the first three is to increase the power wich increases the noise and the fourth one is where the device adjusts its power depending on how clean the air is. It shines red for air thats is really polluted, orange, green and finally blue for air that is filtered.
