Buying Guide: Distilled Water By The Gallon
- Intended use: If you need water for appliances (humidifiers, CPAPs), prioritize distilled water with minimal mineral content and a stable bottle design. For hydration or emergency storage, larger bulk packs may offer better value.
- Size and packing: One-gallon jugs are common and convenient for daily use. Bulk cases save trips but require more storage space.
- Certifications: Kosher labeling and certifications may matter for some households; consider products that clearly state their purity standards if that’s important to you.
- Storage: Store upright, away from direct sunlight and heat. Ensure caps are sealed to prevent leaks and contamination during storage.
- Label clarity: Look for clear labeling about distillation method (steam distillation is common) and any additional treatment (filtration, ozonation) to gauge perceived quality.
- Cost per gallon: Bulk packs typically lower the cost per gallon but require more storage. Compare per-gallon pricing when choosing multi-pack options.
- Allergies and preferences: For households with dietary or religious considerations, verify packaging and labeling for compliance and comfort level.
