Score: 72/100
VEVOR Water Distiller
Score: 85/100Rankings

The VEVOR YMK40230 is a high-performance distiller with the fastest output and highest power in this comparison, featuring a durable stainless steel build and glass carafe. Its high wattage and large capacity make it ideal for heavy use but potentially excessive for small households. It is best suited for offices, laboratories, or hobbyists needing large volumes of pure water.

The CO-Z 1.1 Gallon Water Distiller offers a high daily output of 22.7 liters with UL-certified safety and a stainless steel/glass build. It features activated charcoal filtration but has a slower distillation speed (0.3 gph) than some competitors. It is best suited for users needing high volume and safety certifications, provided they have adequate counter space.
