The evaporated humidifier
has been on the market for decades, it is the most common kind of humidifier. With a very simple principle, it can be simply understood as” drying clothes”.
Use a fan to blow the filter screen or water wheel that can absorb water. The contact area between the filter screen and water wheel is larger, and the faster wind speed allows water to evaporate quickly into the air.
The advantage of evaporated type is that then we would not see the air fog in the air outlet. because the water is firstly evaporated and then sent out. There is no requirement for the position. Another point is that impurities in the water are not blown into the air so that it would not affect the air quality.
One of the disadvantages of the evaporative humidifier is the relatively low efficiency. The second is that the impurities in the water will remain in the water tank, filter, or water wheel, the water tank, and water wheel need to be cleaned or regularly.
Of course, these two humidifiers are just a basic prototype, many manufacturers will add more technology based on the original.
