Parts - BC Charcoal filter with twist lock 

BC Northern Lights changed the charcoal filter attachment a few years ago for the BloomBox and Producer. 

This new configuration provides a push and twist-lock connection rather than having to use a clamp to hold it in place.

Other than the connection update, the BC Activated Coconut Charcoal filter is the same as the previous model and still fits a 4-inch duct.

Easy to install. For the BC dryer, Bloombox or Producer grow chambers, just mount on the main air exchange outlet on the back of the machine.

Depending on the use, these filters will clear the air of growroom odors for approximately 1 to 2 years.
