There are a few key factors to consider when comparing water filtration systems, such as the Alexapure and Berkey. The first is the removal of contaminants. Both systems use similar methods of gravity filtration to remove bacteria, viruses, cysts, parasites, chemicals and heavy metals from water. The second factor is flow rate. The Alexapure system has a higher flow rate than the Berkey, meaning that you can filter more water in a shorter amount of time. The third factor is capacity. The Alexapure system can filter up to 200 gallons of water before it needs to be replaced, while the Berkey can filter up to 4500 gallons before it needs to be replaced. Lastly, price is always a consideration when making any purchase. The Alexapure system costs less per gallon of filtered water than the Berkey system.
In conclusion, both the Alexapure and Berkey systems are effective at filtering contaminants from water. However, the Alexapure has a higher flow rate and lower price per gallon of filtered water, making it the better choice between the two systems.
