Waterdrop King Tank Vs. Big Berkey: Which Gravity Water Filter You Should Get?

by 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.

Berkey

What started as a family business has impressively metamorphosed into a global-scale water purification company. Berkey Filters boasts a generation-long track record of rolling out advanced water purification systems backed by advanced technology. In addition, the company prioritizes home water filtration solutions. The gravity-fed water filter from Berkey is one of the most popular options in the market. The line-up comprises eight different units, all made for domestic use.

The goal of Alexapure is to improve users’ home through the science of air and water filtration. The filtration systems of Alexapure are developed with a passion for innovation. In the process, Alexapure has created breakthrough technologies that give users the cleanest air and water.

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.
