Berkey vs. Propur Water Filters

Choosing a water filtration system can be daunting with the multitude of options out there. That’s why we've compared the Berkey water filter system with the competition so you can decide what’s best for your needs. Here, we’re comparing the Berkey system to the Propur system.

Berkey vs Aquatru water filters

In Summary

Berkey systems will filter the water faster and last longer than Propur water filters. Berkeys also include more filter elements, and are much less expensive over time. They also perform better than Propur.

How Berkey Works

The Berkey is a gravity-fed water system that works for indoor/outdoor use, along with emergency situations. It filters out contaminants, heavy metals, glyphosate and other impurities -- while preventing bacteria growth and keeping the beneficial minerals in the water.

Berkey systems are made of polished stainless steel for quality and style. They can be used by as little as one person to as many as 6 people or more and it takes about one hour to filter one gallon of water.

Our Black Berkey purification element exceeds NSF/ANSI 53 standard tested by State and EPA accredited laboratories and is composed of granular activated carbon. Each Berkey system purchased from Berkey Filters comes with a Berkey Care lifetime warranty.

How Propur Works

The Propur filter system is also a gravity-fed water system that works for indoor/outdoor use, along with emergency situations. It filters out contaminants like heavy metals, glyphosate and other impurities at a rate similar to the Berkey.


Each system is made of 304 stainless steel for quality and style and the ProOne G2.0 Filter Element is composed of granular activated carbon filter and meets NSF/ANSI 53 & 42 standards tested by State and EPA. Propur systems can be used by as many as 4 people or more, but many systems are for one to two people. It takes roughly five and a half hours to filter one gallon of water.

When you initially look at the two systems, Propur seems to be the more affordable choice. But once you compare the costs of the filter, it starts to add up.

The biggest barrier is the initial cost of paying for the system and the filters. For this example we compared the Propur Traveler with our most comparable model, the Travel Berkey. The Travel Berkey costs $249, while the Propur Traveler costs $189. That's where the savings stop. Long term, the Berkey is a clearer choice.

Here we will break down the cost over the lifespan of the Black Berkey Purification Elements. For this comparison we are calculating the cost based on the use of three gallons of water per day.

Each Berkey system comes equipped with two Black Berkey Purification Elements. These Berkey filters will last up to 6,000 gallons with no extra cost incurred. Using 3 gallons per day, the included filters would last you an approximate 5.5 years.

The Propur system comes with one filter. The filter, ProOne G2.0 5" Filter Element, lasts for six months (or three gallons per day) and costs $69.50.

For 5.5 years of clean water, you will need ten additional ProOne G2.0 5" Filter Elements ($69.50). The total cost for all of the replacement filters adds up to $695.00. When combined with the original cost of the system, it brings your total investment to around $884.00 for the Propur system.

When filtering 6,000 gallons of water over five and a half years, the cost per gallon comes out to 15 cents per gallon using the Propur water filter.

The Travel Berkey filter system comes standard with two of the Black Berkey Purification Elements. These purifiers will filter up to 6000 gallons of water which brings the cost to 4 cents per gallon using a Berkey.

When you compare Berkey vs Propur in cost, the unanimous winner is the Berkey Water Filter System.


Both the Berkey and the Propur water filter system do a good job at water filtration by removing contaminants and impurities to provide clean drinking water for you and your loved ones. The Berkey Systems removes over 200 contaminants while leaving beneficial minerals in the drinking water. In our side-by-side comparison chart, we list a few of the most common contaminants in municipal tap water, including: lead, chlorine, chromium VI, copper, and chloroform.

Berkey filters have been tested by independent third-party laboratories to remove these contaminants at a rate of greater than 99.9%, with the exception of chromium VI which is removed at 99.8%. You can find all of the testing results for the Black Berkey Purification Elements here.

According to Propur test results, it removes lead at 100%, chlorine at >99.9%, chromium VI at 98.7%, copper at 89.8%, and chloroform at 98.3%. 

The Propur Traveler is slightly larger than the Travel Berkey at 1.6 gallons, but as noted in the previous section, the filters do not last nearly as long as the Black Berkey Filters. The flow rate is also dramatically longer than the Black Berkey Filter and the purification speed is 0.18 gallons per hour.
