Choose from a wide selection of odour filters, from cheaper options to products designed for professionals. A carbon filter connected to a fan purifies the air in spaces used for indoor growing. The main functional component of these filters is activated carbon, which removes unpleasant odours from the grow tent. Carbon filters are environmentally friendly and have a positive effect on air quality.
When choosing a filter, pay particular attention to the airflow and duct diameter (flange).Check out the inline carbon filters if you want to place the filter outside the grow tent or directly into the ducting.
The second important thing when selecting a carbon filter is the volume of activated carbon. The amount of carbon directly affects the efficiency of the filtration of odours and impurities. PRO-ECO products excel in this regard.
The filters are further differentiated based on the type of activated carbon:
- Pellets are small cylinders with a diameter of 2-6 mm, which absorb air impurities only through their base. Time-tested and proven filters with this type of high-quality charcoal are made (among others) by Prima Klima.
- Granules are chopped pieces of coal (1-5 mm) capable of absorbing particles with their entire surface. As a result, they offer significantly better results than pellets of the same mass. This filter type is made (for example) by PRO-ECO, which uses excellent activated charcoal from Australia.
The filter's weight is often decisive when figuring out how much carbon is in it, but be careful - there's a difference between the weight of the casing and the weight of the carbon. The cover is usually steel - making it durable but not exactly lightweight (ECO VF, Prima Klima). Aluminium is much lighter than steel - so if the filters have the same weight, the amount of carbon in the filter is much higher.
The thickness of the coal layer has a direct influence on the filter's durability. The thicker it is, the longer its lifespan. It is that simple. A characteristic example is the excellent brand Prima Klima, which produces odour filters of the ECO (cheaper and with less thick layer) and Industry (thicker layer, higher price, not insignificantly longer life) lines.
TIP: Be sure to keep the non-woven pre-filter clean. These pre-filters are on the vast majority of carbon filters available and can significantly extend their lifespan.
