Customer Reviews

Fine if paired with a 6" fan Review by Monkey Allen
First, let me say this filter will absorb odors from your growing environment. Here are my issues:
1. I feel like it was only effective for about 6 months
2. A 4" 200 CFM filter doesn't make a whole lot of sense because there aren't any 4" fans that can move an equal or greater volume of air, which is what you apparently need when pairing a fan and filter. To use this filter, you really should be using a 6" fan and a 4-6" reducer to make it fit. If you do that, then only the longevity of the product becomes an issue. I was under the impression these filters should last at least a year; however, I was growing a very stinky plant, so maybe the carbon absorbed all it could within that time period.
