The table below ranks the sites from highest to lowest WFAR Annual Index. Generally, water-from-air system performance is better at more southerly sites. Performance is better along the coast than further inland. During the summer months of July and August, when drinking water scarcity is likely to affect people most, water-from-air systems will offer excellent performance except for Hohhot (fair), Taiyuan (good), and Kunming (good).
China appears to be a worthwhile market for drinking-water-from-air technologies. At least three equipment suppliers are based in the country.
