Aesthetics – A Slight Advantage for Alexapure Pro

Both the Alexapure Pro and the Big Berkey are countertop filtration systems that use gravity to filter water and don't require a power source, making them suitable for both home use and off-grid living or camping.

In terms of appearance, both systems are similar in size and made of stainless steel. The Alexapure Pro has a brushed finish, while the Big Berkey has a polished finish. The Alexapure Pro may have a slightly more modern look due to its brushed finish, but both systems are well-designed and would fit in with most kitchen designs.

Neither system comes in any additional colors, and both have black plastic spigots and handles with the company logo. Ultimately, the choice between the two systems in terms of aesthetics comes down to personal preference. The Alexapure Pro may appeal to those who prefer a more modern look, while the Big Berkey may appeal to those who prefer a more traditional appearance.

Ease of use – Alexapure Takes it for Their Easy-fitting Filters

Both the Alexapure Pro and the Big Berkey are designed for ease of use, with lightweight designs weighing in at only 3.1kg each. They operate in a similar fashion, requiring you to fill the top chamber with water to be filtered, which is then passed through the filters to remove impurities and fill the bottom chamber with purified water.

One advantage of the Alexapure Pro is its easy-fitting filters, which make replacing them a breeze. In contrast, the filters in the Big Berkey may be more difficult to replace and require additional tools.

Alexapure Pro

The Alexapure Pro has a large handle on its top lid with a wide opening for easy water filling. If using an off-grid, it's recommended to strain the water to prevent large bits of mud or grass from clogging the filters. The Alexapure comes with one filter pre-installed and has space for up to four, with more filters installed increasing the speed of filtration.

Installing new filters is simple, as they easily slide into the ports. Initial assembly of the Alexapure is also easy, with the top chamber simply fitting onto the bottom one. Collecting purified water is equally simple, with a handle on the spigot to easily dispense it. It's recommended to run at least one full chamber through every two days to prevent the filters from drying out. If not using the filter for a while, the filters should be removed and stored in a ziplock bag filled with water.

Big Berkey 

The Big Berkey has a similar design and doesn't require any major preparation of the water before filtration. It fits together in a similar way as the Alexapure, although some users complain that the filters can be difficult to fit. The Big Berkey comes with two filters pre-installed.

What Impurities Do They Remove? – Very Close But Big Berkey Wins

Both the Alexapure Pro and Big Berkey countertop filtration systems use their own brand of water filters. Alexapure claims to remove 200 different impurities, while Big Berkey claims to remove slightly more at 203 impurities.

Both systems claim to remove::

  • Heavy metals such as lead
  • Bacteria
  • Viruses
  • Insecticides and pesticides
  • Volatile organic compounds (VOCs)
  • Dangerous chemicals such as chlorine
  • Drugs and pharmaceuticals including caffeine, acetaminophen, and antibiotics like ciprofloxacin

However, Big Berkey's claims aren't backed by any third party and they aren't NSF certified. Alexapure Pro is also missing NSF certification, but they do have laboratory results available for viewing (check the links above).

Comparing Additional Features – Alexapure Wins for Built-in Fluoride Filter

When it comes to additional features, the Alexapure stands out for its built-in fluoride filter. The Berkey also offers an additional filter that speeds up the filtration rate, although it can be pricey and run slowly with only one installed.

In terms of filtration speed, the Alexapure, when stocked with three additional certified filters, has a slightly faster rate than the Big Berkey. This may be a consideration for those planning to use their filter for camping or emergency situations. However, the Big Berkey's filters do last on average 1,000 gallons longer than Alexapure's, which could save you money in the long run.

It's also worth noting that Berkey offers filters specifically designed to filter out fluoride, so if that is a concern for you, it may be worth considering.

Overall, both of these countertop filtration systems offer excellent filtration compared to other options on the market.

Pricing: Berkey's Longer-Lasting Filters Give it an Edge

When it comes to pricing, there is not a significant difference between the two filtration systems. The Big Berkey is typically slightly more expensive, ranging from $20-$30 more, but it does come with an additional filter. While the filters for both systems can be expensive, the Big Berkey's filters have a longer lifespan. This means that overall, the cost of the Big Berkey is a better deal. It's worth considering the cost of replacement filters and the lifespan of those filters when making your decision.

Why Choose the Alexapure Pro for High-Quality Water Filtration

The Alexapure Pro is a top-of-the-line gravity filtration system that can make even contaminated water safe and nutritious to drink. In addition to its excellent performance, the Alexapure Pro has a sleek design that makes it a visually appealing choice for home use.

While the Alexapure Pro filters may not last as long as some other options, they can still process up to 5,000 gallons of water. This is more than enough for the average person's yearly consumption (182.5 gallons).

The Alexapure Pro also has a fast filtration rate, which can be especially important in emergency situations.

Why the Big Berkey is the Top Choice

The Big Berkey is a best-seller in the market and has a high level of popularity, which makes it easier to find replacement parts and filters, as well as being cheaper, compared to the Alexapure Pro. While the Alexapure may have an edge in terms of design, the Big Berkey isn't unpleasant to look at and can even add old-world charm to an off-grid cabin or a traditional wood-finished home.

The Ultimate Showdown: Alexapure vs. Berkey Countertop Gravity Filters

After comparing both the Alexapure and Berkey countertop filtration systems, it's clear that they both effectively remove unwanted contaminants from your water. However, Berkey's Fluoride-specific filters may sway some consumers in its favor.

Additionally, the Big Berkey‘s status as a market leader may also make it a more appealing choice due to its ease of finding replacement parts and filters. On the other hand, finding replacement parts and filters for the Alexapure Pro can be more challenging.

Ultimately, the decision between these two filtration systems may come down to personal preference and individual needs.
