What Do Carbon Filters Remove From Water?

Adsorption Helps Carbon Remove Contaminants

Carbon filters are extremely effective at removing a wide variety of contaminants from water because of it's adsorption properties. Through adsorption, contaminants are attracted to the activated carbon surface and held to it. This is similar to the way a magnet attracts and holds iron filings.

In fact, carbon's excellent adsorption capabilities has made it one of most common filtration mediums used in reverse osmosis drinking water systems, fridge filters, backpacking water filters, and more.

There are two basic types of carbon filters: 

1) GAC Filters

Granular Activated Carbon or "GAC" filters are often used as "polishing filters" in the RO process. GAC filters can remove VOCs, pesticides, nitrates, hydrogen sulfide, and much more.

2) Carbon Block Filters

A variety of contaminants can be effectively reduced or removed by carbon block filters, including VOCs, THMs, mercury, chlorine, and more. A carbon block filter's ability to remove contaminants depends upon the filter micron rating. Some carbon block filters rated at one micron or less (meaning they have a very small pore size) are certified to remove lead, iron, arsenic, cysts, and coliform bacteria.

Can Carbon Filters Improve the Taste of Water? 

Yes, carbon filtration can reduce or remove a variety of contaminants that may affect the taste, color or odor of your drinking water. For example, carbon filters can improve your water's taste by removing chlorine, industrial solvents, polycyclic aromatic hydrocarbons (PAHs), trihalomethanes (THM), organics., and more. That's why many Reverse Osmosis drinking water systems incorporate carbon filtration.
