Sertodo Copper Water Filter System Vs Berkey Water Filter System

In today's post, we are diving into a detailed comparison between Sertodo's Copper Water Filter System vs. Berkey Water Filter System.

From the effectiveness of the filters within each system, to the pros and cons of installing one for your home, this guide walks through everything there is to know about both water filter systems.

First things first, it is important to note that each water filter system has its own advantages and disadvantages. As everyone's needs for drinking water is also different, it is crucial that you carefully decide which water filter system fares better for you and your family. 

Sertodo vs Berkey Water Filter System: How They Work 

Before we start to compare the two filtration systems, let us take a deep look at both water filter systems.

The Sertodo's Copper Water Filter System vs. Berkey Water Filter System are two popular water filtration systems that use different technologies to filter water. 

While both systems effectively remove impurities from water, there are some notable differences between the two.

Our Sertodo Copper Water Filter System uses the most advanced ceramic/carbon gravity feed filters, CeraMetrix GF.  We recommend the use of a minimum of 2 filters for the maximum effectiveness of our copper water filter system.

Below is a list of contaminants Cerametrix removes from unfiltered tap water:

  • Pathogenic bacteria(>99.999% removal of cholera, typhoid, salmonella, E.coli, Fecal Coliform)
  • Cysts
  • Sediments(100% absolute to 0.5 micron)
  • Chloramines
  • Chlorine
  • Flouride
  • Lead
  • VOCs
  • Herbicides
  • Nitrates(>92% effectiveness)
  • Pharmaceutical compounds
  • Metals(Aluminum, Iron, Mercury, Nickel and Zinc) 

You can read the lab report in detail for our CeraMetrix filter here to learn more about its effectiveness on removing water contaminants. 

On the other hand, the Big Berkey Water Filter System uses Black Berkey Purification Elements to filter out the following contaminants:

  • trihalomethanes
  • inorganic minerals
  • heavy metals( includes Aluminum, Antimony, Barium, Beryllium, Bismuth, Cadmium, Cobalt, Chromium, Chromium 6, Copper, Iron, Lead, Mercury, Molybdenum, Nickel, Vanadium, and Zinc)
  • pharmaceuticals
  • VOCs
  • petroleum products
  • perfluorinated chemicals
  • rust, silt and  sediment
  • radiologicals

As the Berkey Water Filter System uses microfiltration to reduce and remove contaminants from tap water, it is quite a slow process to produce cold, refreshing drinking water. 

However, with our Sertodo Copper Water Filter System, you can enjoy instant cold, drinking water as copper is naturally cooling! The oligodynamic effects of copper also make your regular cup of water taste delicious, while you reap plenty of health benefits over time. 

Sertodo's Copper Water Filter System vs. Berkey Water Filter System: How They Compare

Firstly, let us take a look at how both of these water filter system work. Our Sertodo Copper Water Filter System uses a ceramic filter, while the Berkey Water Filtration System uses Black Berkey Purification Elements.

Both systems effectively remove sediments, bacteria, and viruses from the water, but the Berkey system is better at removing chemicals.

By size, our Copper Water Filter System measures 21 inches tall (top and bottom chambers combined), 10 inches diameter of the opening. The Big Berkey is slightly smaller, with the dimensions of 8.5 inches by length and also at 21 inches tall. They are both similar in sizes, and made to be compact enough for tiny homes, RVs and kitchens with limited counter spaces. 

That being said, if you love the elegant glow of copper, our Sertodo Water Filter System definitely looks better! The stainless steel appearance of the Big Berkey 

However, the upfront cost for installing our Sertodo Copper Water Filter System is $583, and you will only need to replace the filters periodically. At $35 each, it is quite an economical water filter system that does not require constant maintenance.

On the other hand, most Berkey Water Filter Systems are bulky, and require regular cleaning for its filters. Their most popular Water Filter System, the Big Berkey Water Filter requires filter replacements every 3,000 gallons of water. If the quality of the influent water is lower, you might even need to replace the filters even sooner than that. 

The Big Berkey Water Filter System cost you $367 to $567upfront depending on how many filters you are using. Besides that upfront cost, you need to also consider the frequent replacements of filters that also require manual cleaning for the water filter system to work.

On top of that, the Big Berkey is also not available for those located in Iowa and California due to purification claims(more on that later).

Comparatively, our Sertodo Copper Water Filter System is made of heavy gauge copper that is meant to last you and your family for many years to come.

The simplicity of our water filter system also means you can set it up, and start enjoying your drinking water without constantly maintaining it.

What impurities does the Berkey filter not remove?

The Berkey Water Filter System is a popular gravity-fed water filtration system that effectively removes a wide range of impurities from water, including bacteria, viruses, chemicals, heavy metals, and sediment.

However, there are some impurities that the Berkey Water Filter System may not remove. These include dissolved minerals like fluoride, nitrates, and some volatile organic compounds (VOCs), which may require additional filtration methods to be removed effectively. 

According to the EPA, the only methods proven to remove nitrates from water are ion exchange, electrodialysis and reverse osmosis. Since the Berkey Water Filter System uses carbon filtration to purify water, it cannot remove dissolved minerals such as nitrates.

Berkey Water Filter System also claims to be able to remove 95% of heavy metals and 99.9% of pathogenic bacteria. According to this article, Berkey is prohibited from selling in California and Iowa because it refuses to comply with proving the above purification claims. 

On top of that, the Berkey filter is also not NSF-53 certified, but our Cerametrix GF filter is. In a nutshell, an NSF 53-certified water filter means that it has been tested and validated by NSF International "to verify the filter’s ability to reduce a wide range of contaminants that are typically found in unfiltered drinking water".

In short, Berkey is not NSF-53 certified to be lead-free, and also does not remove chemicals such as chloride and nitrates. 

The Final Takeaway - Which is the better countertop water filter system?

As you can see, in comparison to the popular Berkey Water Filter System, our Sertodo Copper Water Filter System is superior in terms of longevity, long-term costs as well as the effectiveness of our water filter in removing harmful contaminants. 

If you love great design and enjoying clean and safe drinking water all day, everyday, choose our Sertodo Copper Water Filter System. In addition, our copper water filter system is also heirloom-quality, so that you can enjoy beautiful copper water for generations to come!
