H2o Labs 300SS White
Score: 87/100
CO-Z Water Distiller
Score: 72/100Rankings

The H2O Labs Model 300 is a Best-in-Class countertop distiller producing 3.79 liters daily with a white baked-enamel exterior and stainless steel internals. Its low capacity and need for replacement filters are the main trade-offs. It is best suited for residential home use where users prioritize glass collection vessels and effective VOC removal.

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.
