If we assume that the relative humidity in desert air is 10%, that would mean that 22.4 liters of air at 25 degrees centigrade would contain 2.24 liters of water vapour, or about 0.040 liters of liquid water. We therefore need to process 560 liters of air to get 1 liter of water, or 560 cubic meters of air to get 1,000 liters. The average domestic water usage in Israel (pop. 10,000,000) is about 100 liters a day, so supplying the entire country with water (assuming that the entire country were a desert, which it isn't) would require 560,000,000 cubic meters of air a day, spread out over the entire country. This is a cube 825 meters on a side, daily. Given that the area of Israel is about 25,000 square kilometers, and that a lot of the water will evaporate after use, I'm not worried about any climate effects.
