About Alexapure vs Berkey

Here’s a quick introduction about both water filter brands…

About Berkey Filters

Berkey is a family-owned business that was founded in the late 1990s. The family came up with the business idea because a clean, safe, and healthy drinking water supply was vital for them.

Hence, they founded the brand intending to share their water solutions with everyone. 

Since then, the brand has been progressing and improving the quality and functioning of its water filters. They aim to keep their customers 100% satisfied. 

About Alexapure Filters

Alexapure’s founder named the brand after his daughter, Alexa. Alexapure’s goal is to help you lead a healthy life with the help of the science of water and air filtration.

The brand is passionate about the water filtration systems it manufactures, using cutting-edge technology to provide you with the cleanest water and air. 

Filter Life And Capacity

If you’re investing in a good water filter, we’re sure that you would expect it to last longer and work efficiently. Both Berket and Alexapure water filters have filters that last long, and they also come with an amazing filter capacity. 

Water Filter vs Bottled Water

The water holding capacity of Alexapure’s filters is 8.5 liters. Moreover, the filtration capacity of Alexapure water filtration systems is 5000 gallons of water for five years. However, the capacity can be increased up to 20,000 gallons of water as you can add 3 additional filters. 

Talking about Berkey’s filtration capacity, the filters can last for 3000 gallons of water per filter. As it comes with 2 filters, the system’s capacity goes up to 6000 gallons of water. Berkey water filters last for about 3-5 years, considering you maintain them properly and replace the filters at regular intervals.

Let’s quickly compare the performance of Berkey water filters and Alexapure water filters: 


Alexapure makes gravity water filters, and hence, its filters don’t provide water immediately. However, Alexapure water filters filter water as per 1 gallon per hour.

Hence, these filtration systems perform powerfully and effectively. A private laboratory has also tested these filters, but they don’t hold the actual NSF/ANSI certification


Berkey water filtration systems beat Alexapure water filters in terms of effectiveness. These filters approximately filter 3.5 gallons of water per hour.

Berkey Water Filters

Moreover, Berkey filters most of the contaminants from water with utmost effectiveness. These filters can eliminate over 200 unwanted components from water.
