Best whole house carbon water filter 2021 (activated carbon)

Chlorine is a common contaminant found in-home water because city municipal use chlorine and chloramine chemical to treat water. It’s common to have chlorine leftover that affects the smell and taste of your water. Using a carbon water filter helps remove the chlorine taste and odor in the tap water so you have pure and refreshing water.

Whole-house carbon water filter

Carbon filters are made from organic raw materials that are high in carbon. Such raw material includes coal, wood-based, or coconut shell.

The raw material is heated in absence of oxygen to increase the surface area of carbon.  Also, heating the filter gives carbon more capacity to hold contaminants. That’s why it is also known as a charcoal filter.

Carbon filter has a large surface area therefore has more capacity to hold impurities.

How does carbon water filter work

A carbon water filter removes contaminants using the adsorption method. The filter soaks/absorbs contaminants particles in water like a sponge. The particles stick in the filter and clean water pass through.

What to check when buying carbon filter

  • Pore size

The filter pore size is measured in micron. If the micron is small the better because the finer the filtration

  • Flow rate

Less flow rate or low water pressure gives more time water contact with the surface of the filter and more contaminants the filter soaks.

The more contact time the filter has with the carbon filter surface, the more efficient filtration meaning more contaminants the filter will soak.

  • Types of carbon filter

The carbon water filter is available in two types Granular Activated Carbon filter (GAC) and Activated carbon block (ACB).

Granular Activated Carbon filter (GAC)

Granular Activated Carbon filter focused on capturing chemical contaminants such as chlorine, radon, and VOCs (volatile organic compounds).

It also removes cloudiness, offensive odors, colors, and unpleasant tastes.

After using the GAC filter for sometimes the ability to remove the chemical is used up and require to be changed to work effectively

Activated carbon block (ACB)

Activated Carbon Block filter removes chlorine, VOCs (volatile organic compounds) including insecticides and pesticides.

It also removes chemicals causing bad tastes and odors

The Activated Carbon Block filter focuses on the taste and drinkability of your water and removing chemicals.

What contaminants does carbon filter remove?

  • Chlorine, taste, and odor
  • Perfluorooctanesulfonic acid (PFOS)-used to make fabric, carpet, paper packaging for food and furniture
  • Pharmaceuticals – a chemical found in drugs and can get into water through improper disposal of drug
  • Pesticides and herbicides

How often are you supposed to change the carbon filter?

Changing the carbon filter depends on the contaminants level and water use. If contaminants level and water usage are low the filter can last for long but if the case is vice versa you require frequent change.

It is recommended to replace the carbon filter every six months or 1 year. If you wait for long the filter pores will become full causing the collected particles to break from the carbon and eventually flow in your water supply.

Where to install a carbon filter

A carbon water filter can be installed at the point of entry and point of use

A point of entry is installed to treat water for the whole house. They are installed at the main water supply and treats all water entering your whole house.

The Point of use is installed before you drink, use for cooking or bathing.
