💡 Simple Rule: If you're between sizes, always choose the larger system.
Why? You'll refill less often and always have enough clean water available.
Want a More Precise Recommendation?
Ask yourself these 3 questions:
- Do you use filtered water for coffee, cooking, and pets?
- Do you want to avoid frequent refills?
- Are you planning for emergencies or outages?
If you answered "yes" to any of these → go one size bigger.
Choosing the right Berkey comes down to 3 simple factors:
- How many people are in your household
- How much water you use daily
- How often you want to refill the system
Bigger system = fewer refills + more convenience.
Most people underestimate how much water they actually use for daily hydration. According to the CDC's hydration guidelines, water intake varies based on activity level, climate, and diet—meaning many households benefit from a larger system than they initially expect.
- Drinking
- Coffee & tea
- Cooking
- Pets
