Quick Answer
Many people believe that Berkey filters have a limited lifespan and need to be replaced frequently, or that they cannot filter out certain contaminants like viruses or bacteria. However, these misconceptions are not entirely accurate.
Misconceptions About Replacement Filters
Berkey filters are often misunderstood as needing to be replaced after a certain number of gallons have been filtered. In reality, the Black Berkey filters can last for up to 3,000 water purification cycles, or around 22,700 gallons, depending on usage. This translates to a lifespan of around 8-12 years, assuming 1 gallon of water is filtered per cycle.
Effectiveness Against Viruses and Bacteria
Another common misconception is that Berkey filters cannot filter out viruses and bacteria. However, the Black Berkey filters are designed to remove 99.999999999% of viruses and bacteria, including some of the most common waterborne pathogens like E. coli, Salmonella, and Campylobacter. This is achieved through a combination of adsorption and ion exchange, making Berkey filters one of the most effective water filtration systems on the market.
Filter Maintenance and Cleaning
Some people believe that Berkey filters require regular maintenance or cleaning to maintain their effectiveness. However, the Black Berkey filters are designed to be self-cleaning, and can be easily backflushed with a small amount of water to remove any debris or contaminants that may accumulate. This process can be done every 1-3 months, depending on usage, and can help to prolong the lifespan of the filter.
