Note that adsorption is different to absorption. Adsorption binds impurities chemically on the surface of the charcoal filter rather than physically absorbing them. Activated charcoal is the ideal water filter because it removes toxins from the water without stripping the water of salts and important minerals. We will send a new one automatically every 12 months… too easy!
Because water not only hydrates us, but it also delivers fluoride for our dental health, as well as essential minerals and salts. And because fluoride, calcium, magnesium and sodium are all dissolved minerals with the same consistency as water, they simply pass through our filters. So, unlike many brands of bottled water, a WFA water filter system gives you water with fluoride, minerals and salts that will protect the health of you and your family. All WFA filter systems are independently certified at the highest possible level by NSF International which sets industry standards for water filtration systems for meeting strict guidelines for health and aesthetic qualities.
They are also Australian Standards Watermark Certified, which provides validation for quality and integrity. Contact us to find out more or visit our online store to buy a water filter system online now.

Filtering your drinking water is one the easiest things you can do to ensure you and your family are getting the best tasting, cleanest smelling, and safest drinking water possible.
It's not effective for removing certain toxic organic compounds, significant levels of metals, fluoride, or pathogens. Despite persistent urban legend, activated charcoal only weakly adsorbs alcohol and it not an effective means of removal.
Several factors influence the effectiveness of activated charcoal. The pore size and distribution varies depending on the source of the carbon and the manufacturing process. Large organic molecules are absorbed better than smaller ones. Adsorption tends to increase as pH and temperature decrease. Contaminants are also removed more effectively if they are in contact with the activated charcoal for a longer time, so flow rate through the charcoal affects filtration.
Some people worry that activated charcoal will de-adsorb when the pores become full. While the contaminants on a full filter aren't released back into the gas or water, used activated charcoal is not effective for further filtration. It is true that some compounds associated with certain types of activated charcoal may leach into the water. For example, some charcoal used in an aquarium might start to release phosphates into the water over time. Phosphate-free products are available.
Whether or not you can or should recharge activated charcoal depends on its purpose. It's possible to extend the life of an activated charcoal sponge by cutting or sanding off the outer surface to expose the interior, which might not have fully lost its ability to filter media.
Also, you can heat activated charcoal beads to C for 30 minutes. This will degrade the organic matter in the charcoal, which can then be rinsed away, but it won't remove heavy metals. For this reason, it's generally best to just replace the charcoal. You can't always heat a soft material that has been coated with activated charcoal because it might melt or release toxic chemicals of its own, basically contaminating the liquid or gas you want to purify.
The bottom line here is that you possibly could extend the life of activated charcoal for an aquarium, but it's inadvisable to try to recharge a filter used for drinking water. Actively scan device characteristics for identification. This means that an activated charcoal filter will remove certain impurities while ignoring others. It also means that, once all of the bonding sites are filled, an activated charcoal filter stops working.
At that point you must replace the filter. Sign up for our Newsletter! Mobile Newsletter banner close. Mobile Newsletter chat close. Mobile Newsletter chat dots. Mobile Newsletter chat avatar. Mobile Newsletter chat subscribe.
