Activated carbon filters used in hydro setups are the most effective means of cleansing the extract air of all unwanted odours. These filters work through "adsorption" Simply put, odour causing molecules to stick to the inside of the carbon without increasing its size, leading to a much longer lasting filter.
Premium carbon filters such as the Pure Air range are tested to last.
The carbon filter is working efficiently to eliminate the undesirable odors from our laser cutting machine. I highly recommend this product for any laser cutting/engraving setup that will prevent unwanted toxic fumes released into the atmosphere. Clovis Viscoe - Modeltech Ltd
