I recently bought a 4 inch Carbon air Carbon filter and after two weeks it quit working! Usually they last me about a year and then they get this packaging tape smell. The filter is rated at 200 cmf and my fan is 187 so that shouldnt be a problem and i am running it through two 4x4x8 tents and that shouldnt be a problem. Should i get a hold of the company and try to get a refund? Also what is your favorite brand of carbon filter?
