What Is A Carbon Filter?

Do i need a carbon filter with my water softener – what is a carbon filter?

Carbon filters are a highly effective way to remove impurities from water, and they work by using activated carbon to absorb minerals and other contaminants. When water passes through the carbon filter, the carbon absorbs impurities, leaving the water pure and clean.

If you have a water softener, you may be wondering if you need a carbon filter as well. In this section, we’ll explore what a carbon filter is and whether you should consider adding one to your system.

Explanation Of How A Carbon Filter Works

A carbon filter is a water filtration device that contains activated carbon, a form of carbon that has been treated with oxygen to open up millions of tiny pores between the carbon atoms. When water passes through these pores, the activated carbon traps impurities such as minerals, chemicals, and organic compounds.

As a result, the water that comes out of the filter is clean and pure.

Types Of Carbon Filters Available

There are several types of carbon filters available, including granular activated carbon (gac), block activated carbon (bac), and powdered activated carbon (pac). Each type of filter has its own advantages and disadvantages:

  • Granular activated carbon (gac) filters: These are the most common type of carbon filter, and they work well for removing chlorine, sediment, and volatile organic compounds (vocs).
  • Block activated carbon (bac) filters: These filters are made by compressing carbon particles into a solid block, and they are more effective at removing impurities than gac filters.
  • Powdered activated carbon (pac) filters: These filters are made by grinding carbon into a fine powder and mixing it with water to make a slurry. The slurry is then added to the water being treated, and the carbon particles absorb the impurities.

How To Determine The Right Carbon Filter For Your System

Choosing the right carbon filter for your system depends on several factors, including the type and amount of impurities in your water, the flow rate of your water, and the size of your water softener. Here are some tips to help you choose the right carbon filter:

  • Determine what impurities are in your water: You can get your water tested to find out what impurities it contains. This will help you choose a filter that is designed to remove those specific contaminants.
  • Consider the flow rate of your water: The flow rate is the amount of water that can pass through the filter at a given time. You’ll need to choose a filter that can handle the flow rate of your water.
  • Make sure the filter is the correct size: The size of the filter is important because it determines how much water it can filter at one time. You’ll need to choose a filter that is the right size for your water softener.

A carbon filter is a great addition to a water softener because it can remove impurities that a water softener alone cannot. By selecting the right type of carbon filter for your system, you can achieve the purest, cleanest water possible.
