White Ceramic vs Black Carbon Filters

What makes activated carbon filters better than ceramic filters?

Each type of filter has advantages and is suitable for different water filtration needs. Black activated carbon filters, such as our BOROUX foundation filters, are better because they have higher absorption capabilities, are more durable, and can effectively reduce contaminants for more gallons. Ultimately the decision is based on your unique water needs. Investigate what works best for you.

First, let's dive into what each of these filters are. A black filter is a block or cylinder of activated carbon. It is highly porous, which makes its surface area particularly large. The minuscule pores are so tiny that they physically trap or block contaminants. It's activated because it holds an ionic charge, attracting and bonding with molecules to prevent them from passing through the filter.

What is an activated carbon filter?

Black carbon filters, also known as activated carbon filters, are water filters made from a specialized blend of carbon. Carbon is an element that takes the solid form of either graphite or diamond. Graphite occurs naturally and is the most stable form of carbon. Carbon block filters are made of finely ground carbon, pressed, and formed into a cylindrical shape. Because carbon block filters are so compact, they can filter the smallest particles and contaminants. These types of filters have an extremely enormous surface area.

BOROUX foundation.™ Filters are activated carbon filters.

What is a ceramic filter?

A water filter made from porous ceramic material. Ceramics are generally made of a mixture of clay, earthen elements, powders, and water that is fired and hardened at high temperatures. It is designed to allow water to flow from the outside to the inside of the filter element. The ceramic shell has pores that are so small that it physically blocks contaminants. Ceramic can also remove other less harmful but equally unpleasant particulate debris such as rust and dirt.

The Super Sterasyl™ Filters are primarily composed of diatomaceous earth compressed into ceramic filter shells. The ceramic filter contains granular activated carbon. Super Sterasyl™ Filters last for 535 gallons or six months per filter.

What makes BOROUX black carbon filters better than Doulton British Berkefeld ceramic filters?

BOROUX foundation filters are more effective at filtering contaminants, have a longer lifespan, are more durable, less costly.

Filter Capability and Longevity:

BOROUX black carbon filters are highly effective at improving water quality by removing a wide range of contaminants. The activated carbon technology targets both chemical and organic impurities, resulting in fresher-tasting water. Activated carbon filters excel at reducing organic compounds from water, including chemicals, pharmaceuticals, and other pollutants. The porous surface of activated carbon provides ample surface area for these compounds to bond with, effectively reducing their concentration in the water. The porous structure of activated carbon provides ample surface area for absorption, ensuring thorough filtration.

BOROUX tested chlorine to 6,000 gallons. The British Berkefeld Ultra Sterasyl tested chlorine to only 3030 gallons.

Durable Design and Materials:

BOROUX black carbon filters are known for their durability, offering long-lasting performance and reliability. The activated carbon material is sturdy and resistant to wear, ensuring consistent filtration over time without degradation in effectiveness. Unlike brittle ceramic that can break or crack, the carbon block may chip, but that won't affect its functionality. Whereas if the ceramic cracks, it no longer effectively blocks contaminants.

Cost per Gallon:

Looking at the sticker price, BOROUX is more expensive than ceramic filters. BOROUX foundation filters are $140 for a set of two, whereas a set of two Super Sterasyl Ceramic filters are $94.99. However, when considering the cost per gallon, BOROUX is far and above the more economical choice.

BOROUX filters can effectively filter chlorine for 12,000 gallons. Super Sterasyl can filter chlorine for only a mere 535 gallons.

140 dollars / 12,000 gallons = 0.0116 dollars per gallon (1.16 cents per gallon)

94.99 dollars / 535 gallons = 0.177 dollars per gallon (17 cents per gallon)

Gallons aside, let's take a look at the recommended replacement time. BOROUX states that filter lifespan is variable and doesn't give an exact date for when to replace, however, for this case, let's go off the one-year warranty. The Ultra Sterasyl Ceramic filters must be replaced at six months, half the time of the black filters, so going off that value, BOROUX filters would be $70 for six months.

The higher absorption capacity and longer lifespan of BOROUX filters result in a lower cost per gallon of filtered water over time. With fewer filter replacements and maintenance requirements, BOROUX filters offer excellent value for money and long-term savings.

Adherence for Federal Laws:

BOROUX is dedicated to being compliant with federal regulations regarding water filter consumer products. The Federal Insecticide, Rodenticide, and Fungicide Act of 1947 specifically calls out water filters. It gives strict directions on the claims that can be made with the product. For example, filters that claim to remove living microorganisms (e.g., bacteria and viruses) and or make a public health claim are subject to these federal regulations.

BOROUX is well-versed in deciphering the legalese and well-equipped to implement the requirements. Other filter companies may unknowingly be unlawful or under the assumption that because they meet one requirement that covers them for everything, when in fact it does not. Users can trust that BOROUX filters strive to meet and exceed regulatory standards for water quality and consumer safety.


Ultimately, the choice between black carbon filters and ceramic filters depends on factors such as water quality, specific contaminants present, maintenance preferences, and intended use. Both types of filters have their place in water filtration systems and can be effective solutions for different scenarios. You are in charge of your wellness; you have to decide what works best for you.
