Systemair RVK & CarboAir Extraction Kits
Too early to tell if the carbon filter is any good at taking out nasty smells. The kit is heavy (it fell to pieces in the tent :-( so make sure it us well supported (consider three straps, one under the fan, one under the filter and one supporting the connection between the two). Delivery and service is great.
Happy friendly people who are only to happy to share advice when asked, I will be using this lot again! .
I had a fantastic shopping experience with groworks. Great bunch and very professional.
