Gac Filter Media


Gac filter media is a type of filtration media made from activated carbon. It is commonly used in water filters to remove impurities and contaminants from water. Gac filter media can be made from a variety of materials, but the most common type is made from coconut shell charcoal.

Gac filter media is very effective at removing impurities and contaminants from water, making it an ideal choice for use in water filters.

If you are looking for a reliable and effective filter media, then you should definitely consider Gac Filter Media. This type of filter media is made from high quality materials, which makes it durable and long lasting. Additionally, it is also very effective in removing impurities from water, making it a great choice for those who want to ensure that their drinking water is clean and safe.

What is Gac Filter Media?

GAC (Granular Activated Carbon) filter media is a type of carbon that has been treated with oxygen to open up millions of tiny pores between the carbon atoms. This results in a much larger surface area for adsorption or chemical reactions to take place. GAC filters are used in a wide variety of applications, including water treatment, air purification, and industrial process fluids.

The most common application for GAC filters is in drinking water systems, where they are used to remove chlorine, taste and odor compounds, and certain organic chemicals from the water supply. While GAC filters are very effective at removing contaminants from water, they do have some limitations. For example, GAC filters can become clogged over time and need to be replaced regularly.

Additionally, GAC filters will not remove dissolved minerals or gases from water.

Where are Gac Filters Used?

When it comes to water filtration, there are a variety of different types and methods that can be used. One type of filter that is gaining popularity in both residential and commercial settings is the GAC filter. So where are GAC filters used?

GAC filters, or granular activated carbon filters, are most commonly used in point-of-use (POU) water filtration systems. These systems are designed for filtering small volumes of water, typically at the kitchen sink or under the bathroom sink. POU systems typically include a sediment filter to remove large particles from the water before it passes through the GAC filter.

GAC filters are also used in some whole-house (WH) water filtration systems. These larger systems are designed to treat all of the water coming into your home. In a WH system, the GAC filter would typically be installed after the main sediment filter(s).

GAC filters work by adsorbing contaminants onto their surface as water passes through them. The pores within the carbon particles attract and trap molecules of contaminants such as chlorine, lead, mercury, and VOCs (volatile organic compounds). As more contaminants become trapped on the surface of the GACfilter over time, its performance will diminish and it will eventually need to be replaced.

Depending on your specific needs and usage patterns, a GACfilter should last anywhere from 3 to 12 months before it needs to be replaced.

What is Gac Material?

GAC material is a type of adsorbent that is used in water treatment. It is made from granulated activated carbon, which is a form of carbon that has been treated to make it highly porous. This makes it ideal for adsorbing impurities from water, as the pores can trap contaminants and prevent them from passing through.

GAC material is commonly used in filters for both home and industrial water systems.

How Does Gac Remove Pfas?

Pfas (per- and polyfluoroalkyl substances) are a large group of man-made chemicals that includes perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). They have been used in a variety of industrial and consumer products since the 1950s, including nonstick cookware, water-repellent clothing, stain-resistant fabrics and carpets, cleaning products, polishes, waxes, paints, adhesives and sealants. GAC (granular activated carbon) is commonly used to remove dissolved organic compounds from water.

However, GAC will not remove all Pfas from water. In order to remove all Pfas from water using GAC filtration, a two-step process must be employed. First, GAC filters must be “preloaded” with a solution containing a high concentration of Pfas.

This can be done by either passing the solution through the GAC filter or by soaking the GAC filter in the solution for 24 hours. Once the GAC filter is preloaded with Pfas, it can then be used to remove all Pfas from water passing through it.

Gac Filter Vs Carbon Block

If you’re wondering what the difference is between a GAC filter and a carbon block filter, you’re not alone. Both types of filters are commonly used in water filtration systems, but they work in different ways. Here’s a look at how each type of filter works and what it does:

GAC Filters: GAC (granular activated carbon) filters work by adsorbing contaminants onto their surface. This means that as water passes through the filter, impurities like chlorine and lead are trapped on the carbon granules. Over time, these impurities can build up and reduce the effectiveness of the filter, so it’s important to replace GAC filters regularly.

Carbon Block Filters: Carbon block filters work similarly to GAC filters, but they’re made with compressed carbon particles instead of granules. This makes them more effective at removing smaller contaminants like viruses and bacteria. However, they also require more frequent replacement than GAC filters.


A common question we get here at RainDance Water Systems is, “What is the best GAC filter media for my water treatment system?” The answer to that question depends on a few factors. In this blog post, we will discuss what GAC filter media is and how to select the best option for your specific application.

Granular activated carbon (GAC) is a type of carbon that has been treated with oxygen to open up its pores. This process creates a highly adsorbent material that can be used to remove impurities from water. GAC filters are often used in drinking water filtration systems as they are effective at removing contaminants like chlorine, VOCs, and THMs.

When selecting a GAC filter media, it is important to consider the specific contaminants you are trying to remove from your water. Some types of GAC media are better at removing certain contaminants than others. For example, coconut shell-based GAC is typically more effective at removing organic compounds than coal-based GAC.

Once you have determined the types of impurities you need to remove, you can narrow down your options and select the best GAC filter media for your needs.
