Koalair Activated Carbon Filter – Anti-odor Filter for Extraction in Indoor Cultivation

Frequently asked questions

• What is the Koalair carbon filter for?

  It retains the odour particles from your grow so the fan only expels clean, odourless air outside. This means you don't have to worry about the smell being noticeable outdoors, which is especially important during flowering, when the aroma is strongest. It's the part that gives discretion to the whole extraction system.

• What type of carbon does it use?

  It's fitted with Australian carbon, recognized as one of the most effective and coarse-grained on the market. That carbon quality is what makes the real difference when it comes to actually retaining odour. The filter's structure is also sturdy, built to last.

• How is the Filtrokoa filter installed?

  It's very simple: it's placed at the intake end of the duct that draws in ambient air and carries it to the fan. The important thing is to make sure the joints are well sealed when connecting the duct to the filter. If you notice any leaks, you can seal them with tape so that all the air passes through the carbon.

• What size should I choose?

  The filter size must match the diameter of your fan's duct. Available sizes are 100x300 for 350 m3/h, 125x290 for 450 m3/h, 125x500 for 660 m3/h, 150x300 for 600 m3/h and 150x500 for 807 m3/h. Check your unit's diameter and airflow before deciding.

• Does it take up a lot of space inside the tent?

  No, its size is compact and its weight is lower than other filters. Because of that it doesn't take up much wall space and is easier to hang. This is a real plus if you're working in a tight tent.

• Is it enough during flowering?

  Yes, it's designed precisely for the moment when the smell is strongest, the flowering stage. It filters out odour particles so that only clean air escapes outside. That said, make sure the size matches your fan's airflow so it works properly.
