There are a lot of different types of water filter cartridges, and each one is made a little differently.

In general, though, most water filter cartridges are made up of activated carbon and porous material like zeolite or perlite. This combination helps to remove harmful contaminants from your water while also reducing bad taste and odor.

Some are made of carbon, which can remove chlorine and other chemicals from water. Others are made of materials that trap bacteria and other impurities.

It’s important to know what your cartridge is made of, so you can be sure it is effective in removing contaminants from your water.

So, how do you tell if your cartridge is made of activated carbon or other materials?

If it’s not labeled, you may want to check with the manufacturer. If it is labeled, look at the description. If the water filter cartridge has a “carbon block” in the description, there is a good chance it contains activated carbon.

If the filter cartridge is labeled as “organic block” or “adsorptive” there is a good chance it contains activated carbon, but these terms can sometimes be used to describe cartridges with other materials too

In general, though, almost all water filters that give you clean and great tasting water contain a combination of activated carbon and another material that removes contaminants from your drinking water.
