Alexapure vs Berkey Reviewed
Alexapure made a splash when they launched their own line of water filters, but Berkey has been making quality products since 1976. When looking to purchase a gravity water filter do you go with the new brand that’s growing in popularity or the well-known and trusted giant?
TL;DR – Alexapure vs Berkey Gravity Water Filters
It was a close call, but we believe the Big Berkey edges out the Alexapure Pro due to the lower price, slightly higher number of contaminants removed, and the lifetime warranty backing it.
The Alexapure Pro is still a great filtration system that may be the better choice for some homes’ needs – but that is ultimately going to be a matter of personal preference and what qualities you feel are the most important in your water filter.
|Alexapure Pro||Big Berkey|
|Filtration Rate||4.5 Gallons Per Hour||3.5 Gallons Per Hour|
|Filter Lifespan||5,000 Gallons Each||3,000 Gallons Each|
|Storage Capacity||2.25 Gallons||2.25 Gallons|
Alexapure Pro vs Big Berkey Overview
Alexapure is a relative newcomer to the water filtration industry. The founder couldn’t find a water filter that he wanted to buy so he set out to make one that met his ideal standards.
The Alexapure Pro uses the Alexapure gravity block filter, which incorporates carbon block and hybrid ceramic technology in order to achieve high-quality filtration. The outer casing is made of stainless steel with a spigot on the bottom for instant fresh water access, and it can hold 2.25 gallons of fresh water.
Its dimensions are 9 inches in diameter by 14 inches tall, and Alexapure sells a stand for the filter that makes pouring out fresh water easier. To use it, you simply fill the top compartment and allow the water to filter through and accumulate in the storage compartment below.
The Alexapure Pro comes standard-equipped with one filter, but you can purchase up to three additional filters and install them in the same unit. This will not only increase the filtration rate, it will also extend the lifespan of the filters.
This product can likewise hold 2.25 gallons of fresh water, and you use it the exact same way as the Alexapure Pro. The dimensions are 8.5 inches in diameter by 19.25 inches tall, but the main difference is that the Big Berkey comes in two different forms. One equips two Black Berkey filters, while the other equips four. Adding the extra filters also extends their lifespan and makes them filter water faster.
|AquaTru Countertop Purifier||Big Berkey|
|Semi-Volatile Organic Chemicals||44||52|
|Inorganic Chemicals (Including Heavy Metals)||20||24|
|Radioactive Particles||✓||✓ (24)|
|Total Dissolved Solids||X||X|
|Microbial Cyst Reduction||✓||✓|
Both products put up impressive stats when looking at the contaminants removed across all classes. There isn’t a big difference between the Alexapure Pro and the Big Berkey when comparing the numbers, and they perform similarly on the percentages of each contaminant removed as well.
The Big Berkey tends to do a little better at removing heavy metal contaminants more completely, and it’s also the only one that removes petroleum products and perfluorinated chemicals. The Alexapure Pro, on the other hand, works better on some organic contaminants.

The small difference in contaminants removed makes it unlikely that one is going to be definitively better over the other for your home’s filtration needs. However, you can be completely sure of that by having your water tested to see what contaminants are present in what amounts in your water.
Something to keep in mind is that neither of these products do much for reducing the total dissolved solids (TDS) in your water. This means that if hard water is a problem you’re struggling with, you may want to look into a separate water softening system as well.
In comparison, the Big Berkey has a 3.5 gallon per hour filtration rate with two filters and a 7 gallon per hour rate with four. This is a little slower than the Alexapure system using the same number of filters, and you can expect a 2-filter system to take about 36 minutes to fill the tank.
Filter Lifespan and Durability
One of the main downsides to the Alexapure Pro is that it does not come with an associated manufacturer’s warranty. There’s a 30-day money-back guarantee on unopened products, but Alexapure reviews return requests after 30 days or for opened products on a case-by-case basis.
The Black Berkey filters are rated for 3,000 gallons each. This means that you’ll get anywhere from 4-7 years out of them – again depending on how you and your household use water. The filter capacities are likewise additive for a total of 6,000 gallons for a 2-filter system and 12,000 gallons for a 4-filter system.
Berkey has a lifetime warranty on their products, which offers some peace of mind that the filter housing will go the same distance as the filters themselves.
The National Sanitation Foundation (NSF) and the Water Quality Association (WQA) are two of the main independent organizations that certify water filtration products. To earn certification, manufacturers submit their products to testing by these labs to ensure that products perform in compliance with set industry standards.
While neither the Big Berkey nor the Alexapure Pro have been certified, both have been tested by Envirotek Laboratories. The results of this testing showed that both products met the NSF/ANSI standards 42 and 53.
Standard 42 means that the aesthetic qualities of the water was improved, while 53 means that contaminants with known detrimental health effects were reduced or removed. They just haven’t been certified by NSF or WQA themselves for these standards.
Considering the high filter capacities, you shouldn’t need to worry about replacing the filters for at least 12 years after purchase so the long-term cost is almost negligible.
In comparison, the Big Berkey goes for $278 for the 2-filter model and $388 for the 4-filter model, which is a lot more cost-efficient. Replacement filters are $128 for a two-pack, but while you’ll need to replace them somewhat sooner than the Alexapure filters you’re still looking at very minimal long-term costs.
Types of Models Each Company Offers
Berkey, on the other hand, makes an entire line of gravity filter dispenser systems. These are the other models that are currently offered in that line:
- Travel Berkey
- Royal Berkey
- Imperial Berkey
- Crown Berkey
- Berkey Light
In addition, Berkey also makes two different styles of in-line shower head filters as well as a water bottle filter. They do not offer a pitcher, however the Travel Berkey is designed to be more compact and mobile to bridge the gap between their larger dispensers and a true pitcher product.
Customer Reviews and Complaints
The Big Berkey has a 4.7 out of 5 star rating on Amazon with 1,638 reviews. 86% of the reviews are 5-star, while only 4% are 1-star. The main customer complaints are that rust-like staining appears on the stainless steel housing after some time, and there can be an unpleasant rubbery taste to the water from the filter parts.
