Just like the Berkey water filter systems, these water filters employ gravity to filter water. But these two filters are completely different, other from their comparable filtration techniques.

For each brand, we have gathered together the two most popular counter gravitational filters and compared them to parameters like eliminated pollutants and filtering lifespans to see which one is the most effective and can provide you with excellent water quality from your water supply on a daily basis

Overview for Big Berkey Water Filter vs Zero Water Pitcher

The filter for this water filtration system is Black Berkey components, with a total capacity of 2.25 gallons. Up to 203 pollutants may be removed and 6000 gallons of filter are available. The warranty is up to 6 months for this filter.

The ZeroWater Pitcher, on the other hand, has a total capacity of 10 cups, and the substitute filter for the device comprises five stages. With a filter lifespan of 3 to 5 months it can eliminate just 23 pollutants. The warranty issued is only for 90 days.

Filter Comparison between Berkey and Zero Water filter

Berkey Water Filter

Berkey’s water filtration system employs up to 4 elements of Black Berkey; a system usually has 2 elements, but for an extra cost you may include 2 elements more. The filter components rely on gravitational power to filter water since they are gravity water filters. There is no electricity or water supply connection to the system.

Each element of Berkey consists of six different media kinds. The building features a coconut-coated shell carbon filtration medium that retains pollutants in their small pores while they are adsorbed and stops them from flowing through the filter using water particles.

Two chambers are formed by Berkey water filter systems, one on top of the other. You fill the room with tap water on the top and then wait till it progressively enters the lower chamber. The systems feature a structure of stainless steel. The stainless steel material and structure that makes them robust and prevents corrosion or other harm to the surface.

Zero Water Filter

ZeroWater 5-stage filter

Two filters appear very comparable with the Zero Water Filter versus Berkey water filtration system on the surface. Like Berkey, Zero Water filters are gravity water filter systems which transport H2O to more than 99 percent of dissolved solids, including heavy metals, via five phases of filtration.

A coarser filters screen, a foam dispenser, a carbon and oxidation reduction alloy, an ion exchange resin, an ultrafine screen, an unwoven membrane are the many phases of the water filter system. More about what they perform and the most efficient filtering they provide later.

The ZeroWater Filter is much smaller and simpler, unlike the Berkey filter. The pitcher system is not made of two stainless steel tanks in one, but a filter is attached to the bottom of the lid. The filter is only within the device. The filtration system is progressively filtered for many minutes by adding tap water to the pitcher.

Dimensions and Storage Capacity

The Berkey has a diameter of 8.5 inches, and a height of 19.25inches and is constructed of inox. The tank has a capacity of 2,25 gallons or 36 cups. It is also filled with water from the base. A metal stall that can be placed on that raises the spit for easier pouring is an optional feature.

On the other hand, the ZeroWater Dispenser measures 11 x 9.8 x 19.8 cm and has a freshwater filling glass storage tank. When fully filled, the tank can hold 40 cups and provide water via a bottom spout.

What Contaminants Can Zero Water and Berkey Filters Remove

The remarkable pollutant removal capabilities of the Zero Water and Berkey are famous. Heavy metals, chlorine and other chemicals, fluoride, and much more may both be removed.

The water filtration systems in Berkey are announced for removing more pollutants than the Zero Water system – more than 200 – however Zero Water benefits from NSF certification while Berkey’s claims are solely supported by independent laboratory testing.

In addition to Berkey, the ZeroWater Dispenser uses the total solids dissolved (TDS) which help to maintain water hardness. This feature will not replace a genuine water supplier, although greater than average quantities of TDS might be of interest to homeowners. The best way to find out exactly what is in your water and the filters that must be removed to test it is.


This water filter system has the ability to remove contaminants such as 57 types of organic chemicals which includes herbicides, 40 types of pesticides, 52 types of semi-volatile organic chemicals, 17 types of pharmaceutical drugs, 3 types of disinfectants including chlorine and chloramine, 24 types of inorganic chemicals including heavy metals, 9 types of perfluorinated chemicals, 6 types of petroleum products, and 24 types of radioactive particles.

Besides that, it can also reduce bacteria and microbial cyst. However, it does not have total solids dissolved.

Zero Water

When it comes to the zero water filter system, it has the ability to remove 2 types of semi-volatile organic chemicals, 2 types of disinfectants, 23 types of inorganic chemicals, 1 type of perfluorinated chemical, and it also has total solids dissolved to maintain hardness of water.

However, it is obvious to see that it does filter out as many contaminants as the former filtration system.

Zero Water vs Berkey : Comparing Their Performances


Their long-term reliability is favoured by Berkey water filters and in terms of longevity, you will have a hard time finding a more effective filter, besides berkey H2O filtration systems. Even the most contaminant-based drinking water is treated by the filter components, and you should not find drinking water with high levels of TDS affecting the speed of filtration to produce filtered water.

However, in the field of speed, Berkey does not offer Berkey filters for water, since they have no water pressure or energy to speed up water flow, as rapidly as a haircase and a full-house filter do. While the Berkey filters are quite comprehensive, they are not meant to give you instantly filtered water or drinking water like gravitational filters.

One point to notice regarding the effectiveness of Berkey is that despite the company’s claims for the removal of pollutants have been backed up by hundreds of customer testimonials from pleased customers, Their product is presently not certified by NSF.

Zero Water

On the other hand, Zero Water is NSF-certified for Standards 42 and 53, chlorine, taste and odour reduction and plumage reduction certification. Not only that, it is also quite certain that each water filter pitcher is sold free of charge using the water quality metre that can be used to test the amount of TDS (total solids dissolved) in your water before and after filtering.

The Zero Water was designed to give a comprehensive filtering for a water filter pitcher of its sort in a five-stage filter compressed into relatively tiny filters. In contact with the water filters, water passes first through a filter display that eliminates roost and dust. The second step of the filter, the foam distribution system, eliminates any suspended particles which have not been removed and the third stage is the carbon oxidising reduction alloy.

The 4th phase of the filter is an ion exchange resin. The ion exchange mechanism is that it filters out inorganic substances. Finally, water flows through an ultra-finished and non-woven membrane, removing any remaining suspended particles. Since most gravity water filters are made of just one or two stages of filtration, Zero Water gravity filter is undoubtedly an attractive choice to filter water.

The Zero Water filtration system is not meant to filter water rapidly, and as it contains more filter phases than other water filters of gravity, you should anticipate it almost twice as long. Like the Berkey water filter systems To filter a cup of beverage water, a new Zero Water filter takes little under 2 minutes.

Zero Water vs Berkey Models


All Berkey water filters include a cylinder shaped and stainless steel filters system with a BPA-free plastic construction, in addition to Berkey’s light option. This bpa free plastic unit, which costs little under $300 and includes 2 filtering elements, is the most popular system for small to medium households.

To list down a few, from the smallest to largest capacity, is the travel berkey with 1.5 gallons, big berkey with 2.25 gallons, royal berkey with 3.25 gallons, imperial berkey with 4.5 and the crown berkey with 6 gallons capacity.
