Waterdrop King Tank Vs. Big Berkey: Which Gravity Water Filter You Should Get?
por Dr. Jonathan Doyle - Updated January 02, 2022
Choosing the best water filter system for your home can be challenging. There are
so many options to sieve through to find the best fit. This article extensively compares the Waterdrop King
Tank, Big Berkey and Alexapure Pro water filters. We are confident you will be better positioned to make the
right choice in the end.
How Does the Gravity Water Filter Work?
There are two primary chambers in gravity filters, both sitting on one another. Water enters through the upper
filter of the gravity filter, passes through a filter, and ends up in the lower chamber. This movement is due to
the force of gravity. You can then get filtered water out of the lower chamber by switching on the small inbuilt
dispenser.
Gravity filtration systems are designed to work based on the universal law of gravitation. That is why the water
can travel freely from the upper to lower chamber, while passing through the filter elements. There are millions
of microscopic pores in the filter elements. These pores ensure that only water molecules pass through the
filter, trapping most other molecules in the process.

water filter from Berkey is one of the most popular options in the market. The line-up comprises eight different

systems of Alexapure are developed with a passion for innovation. In the process, Alexapure has created

Product Introduction
Waterdrop King Tank
The King Tank offers a thorough filtration performance, especially when reducing contaminants in water. It
relies on black and fluoride filters to deliver a premium filtration performance. In addition, the premium
carbon block effectively absorbs several impurities such as sediment, rust, sand, odor, and bad taste.
The uniform particles, coupled with the smooth surface, ensure the black
filters can efficiently reduce chlorine and remove bad taste. The much cleaner water then moves through
the granular activated carbon, where it is subjected to further filtration to ensure improved taste and quality.
The white fluoride water filters use advanced resin and granular activated carbon, and food-grade fluoride
reducer to reduce up to 98% of fluoride in water. Therefore, the filtered water has a better taste and no odor.
It is also important to mention the jointless and user-friendly design of the King Tank. So, you can rest
assured of getting cleaner and safer water any time, any day.
Furthermore, you count on the King Tank filter to meet your household’s daily water needs, thanks to its
ultra-large size. Waterdrop also includes all the accessories you need to start using this water filter system
in the box, including water level spigot, wrench, and anti-slip stand. You get to save up to $100 on these
accessories by getting them out-of-the-box.
Big Berkey
Berkey has a great reputation for household water filtration solutions, especially the highly-rated gravity-fed
water filters. This particular unit delivers an impressive filtration performance due to its extensive research
and developmental process.
As tests have confirmed, it can effectively reduce up to 98% fluoride in water. It is also effective against
over 200 contaminants present in water. In addition, the filter elements in the Black Berkey are in line with
NSF standards, although they are yet to be NSF certified.
The holding capacity of the Big Berkey is 2.25 gallons, with two purification elements capable of filtering
3,000 gallons each. The filtration rate is 3.75 gallons per hour. You can choose other sizes based on your
household water consumption rates.
Alexapure Pro
The Alexapure Pro water filtration system is also a gravity fed water system that targets over 200 contaminants
including heavy metals and chlorine. It also has a stainless-steel design, and is tested to NSF/ANSI Standards.
The Alexapure Pro is able to filter 5000 gallons of water per filter element inserted into the filter chamber.
The big difference between Alexapure and Berkey is that Alexapure removes fluoride and arsenic from water. If
you want to remove these contaminants with a Berkey filter, you have to buy a separate filter. This filter is
quite pricey and needs to be replaced more often than their Black filters.
Which Water Filter Should You Buy?
All the three products are excellent household water filtration solutions offering similar capabilities.
However, the ultimate choice will depend on your preferences. For example, the King Tank’s premium filtration
performance, while Berkey offers you more selections. Likewise, you get free accessories with the Waterdrop King
Tank, including the water level spigot that allows easy tracking of your water level.
Overall, the King Tank has all it takes to provide you with a unique user experience. After all, that is one of
Waterdrop’s strongest points.
