This may be a good solution in many places where ground water is not available, or where the groundwater really sucks. But you fail to mention some issues with getting water from air (same for rain water collection)
Humans are throwing tons of chemicals into the air and they will get trapped in the condensate. Pollution, fertilizers, emissions from coal and gas power plants, all end up in the water and, concentrate.
As long as these things have carbon filters and UV lights they are probably fine, but i think its important to mention this.
