Activated Carbon
Every odour filter has a limited lifespan - after some time, the activated carbon simply stops absorbing odours. Then you need to replace either the entire filter or take it apart and refill it with new carbon. Our range includes carbon with CTC 70 in pellet form, in packs from one kilogram up to 25 kg bags.
We will be happy to advise you on filter refurbishment. Just get in touch at info@higarden.cz.

Activated carbon is the term for carbon specially treated to give it better adsorption properties - so it binds molecules more effectively. Activated carbon for odour filters has a porous structure and a large surface area (up to 1,500 m2/g), which enables it to bind molecules of unpleasant odours moving through the air. In general, the larger the surface area, the more efficiently it absorbs odours and removes chemicals in the form of gases and vapours from contaminated air.
Our range includes CTC 70 pellet carbon. CTC describes the internal porosity of the material and therefore the area of its surface. You can choose packs from one kilogram up to 25 kg bags.
Refurbishing the filter pays off for many growers - instead of having to buy a new filter every time it stops working (which can be every six months or every year, depending on the conditions in a particular tent or room), they simply replace the filling. The filter will not work quite as well as a completely new one, but it will certainly delay the need to replace the entire filter.
After all, the carbon is packed into the filter by the manufacturer so that there are not too many air pockets between the individual pellets. They use specialised tools that are not available to ordinary users. Replacing the carbon therefore means that you do not have to pay for the entire filter again, but its efficiency will be slightly lower than that of a completely new one.
