AquaTru vs Berkey: Which Water Filter Is Better for Your Home?
If you're comparing AquaTru vs Berkey, you're choosing between reverse osmosis and gravity filtration.
Short answer: AquaTru uses reverse osmosis for very high dissolved-solids reduction. Berkey systems use gravity filtration with larger capacity and no electricity.
Note: Filter availability has changed. See Are Berkey Filters Safe? Full 2026 Guide.
AquaTru vs Berkey: Quick Comparison
| Feature | AquaTru | Berkey |
|---|---|---|
| Filtration Type | Reverse Osmosis (RO) | Gravity Filtration |
| Contaminant Reduction | Extremely high (nearly all dissolved solids) | Broad reduction of many tap-water contaminants |
| Water Capacity | Small tank (about 0.5–1 gallon) | 1.5–6 gallons depending on model |
| Electricity Required | Yes | No |
| Water Waste | Produces wastewater | No wastewater |
| Best For | Very low dissolved solids | Daily tap water, families, power outages |
What’s the Difference Between AquaTru and Berkey?
- AquaTru forces water through an RO membrane and removes nearly everything, including dissolved solids and minerals.
- Berkey uses gravity-fed filtration to reduce many contaminants while helping keep beneficial minerals.
Filtration Performance
AquaTru is strong on fluoride, metals, and dissolved solids. It also strips minerals and wastes water.
Berkey reduces a broad range of tap-water contaminants and leaves minerals in.

Water Capacity & Daily Use
AquaTru’s tank is small, so families refill often.
Berkey holds more water at once, which helps for:
- Families
- Cooking and drinking
- Use during a power outage
Size help: what size Berkey you should buy.
Cost Comparison
AquaTru often costs less up front, then replacement filters add up. Berkey costs more at first; long-life elements can cost less per year. See Berkey cost per year.
Ease of Use
AquaTru needs electricity. Berkey is fill-and-wait gravity. That matters when the power is out.
Maintenance
- AquaTru: several filters on different schedules
- Berkey: chamber cleaning and long-life elements
Pros & Cons
AquaTru Pros
