Most importantly, this exhaust fan does NOT come with bolts/nuts to attach the filter holder to the fan. To be honest I almost broke the deal until I remembered the tape existed and now it's working again. Also, the plain bearing sticker was incredibly oily out of the box. Asks me about the durability of the bearing but at $17 for a fan, 4 filters and a filter holder I think this is the cheapest fume extractor I have found. It seems to suck pretty well at about half a foot away, so I put it…
