The study on using nanoporous materials for harvesting water from the environment is still in its early stage, involving multiple methodologies, materials, and levels of technology. Insight on several experimentally novel directions shed light on the challenges and prospects associated with atmospheric condensation behavior, pressurized filtration, and ion adsorption on various nanoporous materials. The condensation of water throughout the surface of a porous cylinder was found to be difficult to extract in large quantities. In pressurized filtration, zeolites exhibit ion exclusion effects. It is also found that nanoporous carbon discs have a relatively low capacity of adsorption which is one order of magnitude insufficient to achieve a detectable decrease in solution salinity
