Detailed Comparison: AquaTru vs. Berkey

Let’s review the performance, effectiveness, cost, maintenance, and warranty of AquaTru and Berkey filtration systems in detail.

Annual Cost

An AquaTru water filtration system costs around $300-500, depending on the size and model. AquaTru water filters don’t require much maintenance but can cost about $100 for repairs and accidental damages.

An AquaTru water filtration system uses a combination of three filters, which sum up to $100-120. On average, the annual cost of an AquaTru water filter is a minimum of $500-720 for the first year and $200-220 for the upcoming years.

In comparison, a Berkey water filtration system starts at roughly $230 and goes up to $590. Berkey water filtration systems come with a general home maintenance kit costing $25 and optional professional maintenance costing $100.

AquaTru water filtration systems have a limited warranty of 1-2 years (depending on the model), but they last up to 2-3 years.

Berkey water filtration systems have a guaranteed warranty of 1-2 years, but they last for decades.

Filtration Method

AquaTru relies on reverse osmosis, one of the purest filtration methods.

Reverse osmosis forcefully pushes water against a fine membrane, removing up to 99% contaminants. Reverse osmosis has countless benefits, including improving taste, preventing odor, and controlling water pH.

AquaTru’s water filtration system uses 4-stage RO technology to achieve maximum purity. The water in an AquaTru water filter goes through a sediment filter which removes major physical contaminants like dust and debris.

An activated carbon filter removes chlorine and chloramines, and the main RO filter removes other contaminants. The filtered water then runs through a final VOC carbon filter to improve taste and quality.

Thus, AquaTru achieves maximum purity and quality by running water through four highly-refined filters.

On the other hand, Berkey uses gravity-fed filters, which are a little traditional, but they get the job done. Berkey uses gravity to force water through a filter, so it doesn’t require electricity.

A typical Berkey filter contains two main chambers; water pours into the upper chamber and movies through a filter into the lower chamber. The system uses an activated carbon and an ultra-filtration filter.

The activated carbon filter removes chlorine, chloramines, pesticides, industrial solvents, and many more contaminants by attracting them; this removal is carbon absorption.

The gravity pulls the water downward through an ultrafiltration filter which removes up to 90-100% of pathogens by separating low-eight molecules from heavy-weight. Although the system is a little simple, it can take a long time to filter water.

Filtering Capacity

AquaTru’s VOC filter has a capacity of 600 gallons, while its RO membrane lasts up to 1200 gallons. AquaTru’s VOC filter will last a year, and the RO membrane will last two years.

Berkey’s filtering capacity depends on the model, but its activated carbon and ultrafiltration filters collectively last up to 3000 gallons for 2 years. Adding additional filters will boost the filtering capacity to 12000 gallons for 8 years.

Holding Capacity

Most AquaTru models have a holding capacity of 1 gallon and 3 quarts, while Berkey’s water filters can hold a little more than 2 gallons.


AquaTru’s filters last 1-2 years (1 year for VOC and 2 years for RO membrane). The overall lifespan of AquaTru filtration systems is 2-3 years, with one year of warranty.

Berkey’s water filters easily last 4 years (2 years for activated carbon and 2 for ultrafiltration filters). The overall lifespan of most Berkey water filtration systems is 10 or more years.

Removal of Contaminants

AquaTru water filtration systems can remove up to 83 contaminants, while Berkey removes more than 200. Let’s see which major contaminants both filtration system tackle:

Common Water ContaminantsAquaTruBerkey
*Note: There isn’t much proof that RO filters can remove acetone because it is typically removed by aeration and carbon filtration. This is why we can’t say for sure if AquaTru removes acetone.
Berkey can remove silver, but its filter typically removes sediment minerals but intentionally leaves ionic minerals to retain purity. Silver can be leached from sedimentary rocks like quartz, which also exists in ionic form, so whether or not Berkey removes it depends on the form.
There are numerous contaminants that Berkey and AquaTru can remove but aren’t listed here.

Performance and Effectiveness

AquaTru uses RO technology, a fancy way of saying it’s great at removing contaminants and purifying water. AquaTru water filtration systems can remove up to 80+ contaminants and maintain water quality and pH.

Berkey water filtration system tackles more than 200 contaminants, removing each at least 90-100% to achieve maximum purity. Berkey’s ultrafiltration filter can maintain taste and quality and prevents odor.

Comparatively, both filtration systems guarantee maximum performance, so we can’t put one over the other.

Energy Consumption

AquaTru uses RO technology, roughly 1-2 watts per gallon. Although this is quite low, most AquaTru users should expect a minor boost in their electricity bills.

On the other hand, Berkey’s gravity-fed filters don’t need electricity, so their power consumption is literally 0.

Filtration Speed

AquaTru’s filters use modern tech and design, so they’re unbelievably fast.

A typical AquaTru filtration system can filter a single liter in 3-4 minutes, while Berkey can filter a full tank in 45-60 minutes.


AquaTru has NSF 42, 53, 58, 401 and P473 certification.

  • NSF 42 certification declares that AquaTru filters can remove contaminants like chlorine.
