Evaluate large water distillers using water testing, verified contaminant reduction, real production rate, energy demand, storage, cleaning, sanitation, and cost.
Evaluate portable water distillers by source-water risks, contaminant limits, output, heat requirements, maintenance, portability, and true cost per gallon.
Understand what water distillation removes, what may pass through, how it compares with other treatments, and how to calculate the true cost per gallon.
