Just crack a window if you can for venting?

And use that little carbon scubber when you flower
desertfox Reviewed by desertfox on . HEPA Air Purifiers anyone? Greetings all, Looking for some feedback. Reading through many of the Indoor threads, it looks as if odor is a big concern for many. It is for me as well. I have a small bedroom that serves as the grow room which is above-ground that I need to keep odor-free and I can not vent via a window. I am leaning towards a HEPA Air Purifier. HEPA Air Purifiers rotate air 6x an hour and good ones can be had for under $200. This is different then say the Vaportek, which serves more like a mask Rating: 5
