Charcoal is made by burning organic matter, such as wood, until it’s turned into a black powder.

The resulting powder is highly porous and can absorb much liquid.

-This is why charcoal is used for filtering water—it can remove impurities and toxins from the liquid, making it safe to drink.

Various forms of charcoal offer different benefits.

So which one is right for you? Read on to find out.

Is a charcoal filter better than a regular filter?

Other filters are exceptionally fruitful at filtering fluids. However, activated charcoal channels do considerably more.

Besides the fact that activated charcoal channels trap residue and trash, they likewise trap debris and smells. The charcoal found in charcoal filters isn’t what you’d toss on a bbq pit.

The Pros of Activated Carbon:

This filter media is very effective at removing and even improving the taste and odor of your drinking water.

Other contaminants can also be removed, including iodine and chlorine residuals, radon, detergents, certain artificial chemicals (usual pesticides), and volatile organic chemicals (typically paint thinning products).

Activated carbon is a popular water filtration medium, and it is used in many commercial and home water filtration systems and for industrial applications such as wastewater treatment.

However, you should be aware of some drawbacks to using activated carbon before deciding whether it is the right choice for your application.

Activated Carbon Has a Short Shelf Life

Activated carbon has a concise shelf life and must be replaced after several months or weeks.

This is why many commercial water filtration systems use granular activated carbon rather than powdered activated carbon to filter water.

The granules are more accessible to replace when they become saturated with contaminants than a powder.

Activated Carbon Can Be Costly

The cost of activated carbon can add up quickly when you consider how much of it you will need for your application.

For example, if you have a large fish tank or pond, you will need a lot more granular activated carbon than someone who only needs it for drinking water or other single-use purposes.

This means that the cost of activated carbon can vary widely depending on what type and amount you need for your application.
