Comparison of Water Filtration Systems

We assert that Berkey® water filters outperform most other water filters on the market. Of course, you don't have to take our word for it! Or at least not without proof and a factual, precise analysis. That's why we decided to compare our purification system with other water filters on the market. These comparisons are based on various important criteria such as cost per filtered liter and filtration capabilities, so you can compare transparently before making your choice.

We focus on the cost per filtered liter because the purchase price of a system should not overshadow the replacement cost of filters and their lifespan. A cheap system to buy can be very expensive if you have to replace your filters every month... It is essential to calculate the cost of this filtration considering these criteria before making a purchase. Also, check that the system you are considering has the required filtration performance for your intended use: filtering only tap water, rainwater, river water, or water from any source in an emergency situation.

All Berkey® systems come with a pair of Black Berkey® filters, tested to be usable up to 22,700 liters. These filtration systems, equipped with these filters, fall into the category of water purifiers, capable, among other things, of filtering viruses.
