Anti-odour Filters

What are Active Carbon Odour Filters?

When indoor growing became a reality, many factors needed drastic improvement, one of them being the pungent aromas produced by cannabis plants. As we all know, cannabis plants possess a powerful aroma that, when you have an air filtration system in your grow room, ends up being pushed out of your grow room or tent.

The game changed when active carbon odour filters found their way onto the market; they’re a highly efficient way of getting rid of any leftover aromas from your growing room or tent.

These odour-filters are cylindrical and contain active carbon on the inside. This carbon “traps” the molecules in charge of cannabis aroma (terpenes), expelling clean air outwards.

How do Active Carbon filters work in Indoor Grows?

As we were saying, the filter inside carbon filters traps the aromatic molecules produced by cannabis and absorbs them.

These filters have a membrane used to protect them from dirt, and they’re placed at the start of your extraction set up.

When growing cannabis indoors you absolutely have to renew the air in the room and this is done using an extractor that expels air outwards and is usually on 24h.

Where to Place an Anti-Odour Filter

In order to correctly install an anti-odour filter and have it work correctly, you’ll need to connect it up to the start of your extraction fan system. This is usually done using ducting. Keep in mind that the extractor and filter must be compatible in strength and diameter. If the diameter isn’t the same you can always use an adaptor.

Make sure to place the filter BEFORE the extraction fan so that all of the air goes through the filter before it hits the fan.

Active carbon odour filters are usually placed up high in grow tents and rooms. The reasoning for this is that air intraction is usually done at the bottom of the tent or room, that way the air is flowing from top to bottom and reaches all of the plants.

There are different carbon filter models to fits different growers’ needs. Some anti-odour filters, designed for large grows, weigh quite a lot and they simply can’t be hung from your grow tent or room – you can acquire stands for such devices.
