Air-to-Water Systems

Air-to-water systems for homes are not mystical atmospheric machines—they are disciplined plumbing around surfaces that already condense moisture. The Air-to-Water Home Guide treats packaged dehumidifiers, high-efficiency AC coils, and dedicated AWG cabinets as interchangeable harvest interfaces, then standardizes everything downstream: food-grade collection, pressurized filtration, ultraviolet disinfection, and opaque storage. Readers land here when they need physics-first explanations before touching a shopping list.

Quick answer: estimate daily yield with the condensate calculator, design the sanitation train, then size opaque storage—never invert that order.

Budget Water Harvesting

FAQ

Physically yes—both harvest latent heat as liquid water—but AWG marketing often implies standalone machines. This hub treats HVAC condensate as the budget harvest path.

Below roughly 25% RH at typical indoor temperatures, daily yield often drops under one liter per square meter of coil area without active desiccants.

Municipal codes vary. Even where condensate reuse is allowed for irrigation, potable use may require treatment documentation—check local health department guidance.
