Berkey vs Aquatru water filters

How Does a Berkey Work?

The magic, or really the science, of Berkey is in the unique filters. Two Black Berkey Filters come standard with every system. The filters are an exclusive and top-secret combination of media that prevents contaminants from passing through. The Black Berkey Filters are composed of granular activated carbon that have been vigorously tested and exceed NSF/ANSI 53 standards. The water that does flow through the filter is pure and toxin-free.

It takes about one hour to filter one gallon of water. The systems are sufficient for one person or up to a large household. It can be used indoors, outdoors, every day or in emergencies. 

Each Berkey system purchased from comes with a Berkey Care Lifetime Warranty.

How Does Propur Work?

The Propur water filter system is similar in the fact that it also uses gravity. It filters out contaminants like heavy metals, glyphosate and other impurities at a rate similar to the Berkey. It can also be used indoors, outdoors, or in emergency situations.
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 and 42 standards tested by the State and EPA. Propur systems can be used by as many as four people but many systems are for one to two people. It takes roughly five and a half hours to filter one gallon of water.

Comparing Costs

At first glance, Propur seems to be the more affordable choice. Looking deeper, Propur actually comes up more expensive than a Berkey system. The cost of the system, plus the cost of the filters exceeds the cost of a Berkey system which automatically includes two filters.

Comparing the two most similar models, the Propur Traveler and the Travel Berkey, which one is the better deal? The Travel Berkey costs $345, while the Propur Traveler costs $189. That's where the savings stop, over time the Berkey system is more budget friendly. 

Each Berkey system includes two Black Berkey filters. These filters last up to 6,000 gallons. At a rate of three gallons per day, the filters should last approximately five and half years. Not costing anything more after the initial purchase until several years later.

In contrast, the Propur system comes with only one filter. The filter, ProOne G2.0 five inch Filter Element, lasts for a mere six months. At least ten ProOne G2.0 5" Filter Elements ($69.50) would be needed to match the five and half years of clean water that Berkey can provide. The total cost for all of the replacement filters adds up to $695. When combined with the original cost of the system, the total investment to a whopping $884 for a 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 cost per gallon for a Travel Berkey is 5 cents per gallon using a Berkey. The cost is based on the use of three gallons of water per day.

Cost versus cost of Berkey vs ProPur--Berkey is the undeniable winner.

Performance Similarities and Differences

Both the Berkey and the Propur water filter system do a good job at water filtration. Both remove contaminants and impurities to provide clean drinking water for families and individuals. However the Berkey Systems stands out because it removes more contaminants better. 

Berkey filters have been tested by independent, unbiased, third-party laboratories. The results from these test show the Berkey filters remove contaminants at a rate of greater than 99.9%, with the exception of chromium VI which is removed at 99.8%. 

According to Propur test results, lead is removed at a rate of 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 with a holding capacity of 1.6 gallons than the Travel Berkey which holds 1.5 gallons. Even those the system is ever so slightly larger, the filters do not last nearly as long as the Black Berkey Filters. The flow rate is also significantly slower than the Berkey system.
