ZeroWater vs Berkey: Key Comparison Factors

ZeroWater vs Berkey

Here are the key comparison factors for ZeroWater vs Berkey: 

Filtration Technology

The ZeroWater filter system comprises several stages: rough filter screen, carbon & oxidation reduction alloy, foam distributor, ultra-fine screen, non-woven membrane, and an ion exchange resin. When you pour water into the pitcher, the filter slowly purifies it in minutes.

Berkey’s filtration system comprises six distinct types of media in each element. One is the coconut shell carbon filtration media, which adsorbs impurities in its minute pores and prevents them from passing through the filter alongside the water particles.

Berkey water filters consist of two chambers, with the upper one filled with tap water. The water slowly passes through the filter and collects in the lower chamber, where it becomes purified and safe to drink.


ZeroWater and Berkey are renowned for their exceptional ability to eliminate contaminants from water. These two brands can remove many impurities, including chlorine, heavy metals, chemicals, and fluoride.

ZeroWater filters water through a 5-stage filtration process and removes 29 contaminants. Whereas, Berkey water filters use microfiltration technology to eliminate 232 contaminants.

ZeroWater filters are certified by NSF. They come with a free water quality meter that can be used to check the number of TDS in water before and after the filtration process. On the other hand, Berkey water filters don’t hold NSF certification.

ZeroWater filters last about 3 to 5 months. On the other hand, Berkey water filters have a 6000-gallon lifespan.

The ZeroWater Filter has a simplified and compact design. It is a pitcher system with a filter placed inside the unit. Whereas, Berkey water filters are incredibly sturdy, made of stainless steel, and resistant to rust and other surface damage.

ZeroWater takes about 44 minutes to fill the 36-cup storage tank. At the same time, Big Berkey takes only 36 minutes to fill the same amount.


ZeroWater tank has a 2.5-gallon or 40 cups capacity. On the other hand, the Big Berkey tank has a 2.25-gallon or 36 cups capacity. Both include a spout at the bottom to dispense water.
