What Is The Cost Of Ownership Of The Alexapure Pro And The Big Berkey Water Filters? Which Is More Affordable?
This is another area in which both the Big Berkey Gravity-Fed Countertop Water Filter and the Alexapure Pro Water Filtration System are quite similar. They are both incredibly close in terms of price, but in the end, the Alexapure is the cheaper option over the Berkey.
The Berkey filters are more expensive than the Alexapure filters; however, they also last longer. While the Alexapure filters feature a filter life of around 5,000 gallons of water (or around 3 years of use until you have to purchase replacement filters), the Berkey ones will last you around 6,000 gallons of water (or around four years of use). So in the short term, the Alexapure filters are the cheapest option, but in the long term, the Berkey filters will likely cost you less money as the price per gallon for the Berkey is 4 cents while the price is 6.2 cents for the Alexapure.
What Is The Capacity and The Flow Rate Of The Alexapure Pro And The Big Berkey Water Filters? Which Has The Highest Capacity And Flow Rate?
Both the Big Berkey Gravity-Fed Countertop Water Filter and the Alexapure Pro Water Filtration System offer dual 2.25-gallon water tanks for a total capacity of 4.5 gallons of water. The Berkey filter (when featured with the maximum number of elements – four Black Berkey filter elements) provides a 7 gallons per hour flow rate while the Alexapure filter provides a 9.2 gallons per hour flow rate (also featured with the maximum number of filters).
These numbers can fluctuate depending on the types of filters you choose to put in your Berkey filter – while the Alexapure only features one type of filter, Berkey has several that you can choose from:
- The Travel Berkey (1.5 gallons)
- The Big Berkey (2.25 gallons)
- The Royal Berkey (3.25 gallons)
- The Imperial Berkey (4.5 gallons)
- The Crown Berkey (6 gallons)
- The Berkey Light (2.75 gallons) (made with BPA-free plastics)
This one is a hard one to judge since, on its face, the Alexapure is the more powerful water filter. On the other hand, however, the Berkey does offer a significant list of water filter choices, some of which would end up outperforming the Alexapure on both water capacity and water flow rate. Whichever water filter you believe to be the winner here will mainly depend on whether you would be willing to spend extra money for the higher capacity Berkey filters.

What Is A Gravity Water Filter?
There are several different ways through which you can filter water in your home. A gravity water filter is one of them. As the name suggests, this type of water filtration system uses gravity in order to filter through contaminated water. In this kind of water purifier system, there are two chambers, an upper chamber, and a lower chamber.
The contaminated water is poured into the upper chamber and the filtered water is collected in the lower chamber after it is passed through a carbon block filter element with microscopic pores. These pores are big enough to let water molecules through but small enough to not allow contaminants through. These kinds of water filters are more economic and do not require plumbing or electricity for them to function. There are many more types of water filters, which you can find here:

What Is A Countertop Water Filter?
This section refers to the placement of the water filter product in your home and how it is attached to your water line and your water supply. A countertop water filter refers to a kind of water filter that is attached to your sink faucet through a diverter tube and, as the name suggests, is placed on your countertop.
It diverts the incoming water from your faucet into the filter, gets filtered through the cartridges, and comes out through your filter’s own faucet and back into your sink. These kinds of filters often have a high capacity and they can switch easily between filtered and unfiltered water. They also require installation and often need a decent amount of space on your counter. If you would like to check out other types of water filter products, you can check out this next list:
