My concern is how long will it last. If you spread the cost of a carbon filter over it's life it's probably cheaper. Mine has been going for nearly 5 years and no odor yet.

Ive found a product what works fantastic, there called Ona Odour Netralizers, all you need to do is buy the Ona Gel which comes in like a jar and stab some holes or remove the lid then place in your grow room these cost £20 for a small tub or £50 for a large tub, and if your grow rooms massive which is unlikely if your on a budget, then you can get an Ona breeze fan Rating: 5
