It’s kind of hard to tell, but they do work….
I’ve had these Nature Fresh bamboo charcoal air purifying bags for a couple of months now, and I’m happy with them.  Our house has a couple of areas that always smell musty, although we can’t figure out why, and I put two each of the biggest bags (there are four of those) in each of those areas, and they’ve helped reduce the odor in there, and make things smell a little fresher.  I also put the medium ones in a couple of our closets, where things get a little stuffy.  It’s a little harder to tell whether those are having any impact in there, because there weren’t a lot of smells to begin with anyway, just kind of stuffy.  And I wouldn't really expect these to do much about "stuffiness".  But they certainly haven’t hurt anything.  And finally, I put the other two in my "Ugg-like" boots that I keep at work, for when my feet get cold.  Those are a real smelly challenge (!), and the charcoal has helped with the smells from those too.  The fabric the bags are made from is nothing spectacular, but it’s pretty, and they are well made and look nice.  So, all-in-all, I’m happy.<br /><br />There are a couple of little issues with these, though, just to be aware of.  The wall-hooks in the first picture aren’t included, although the two with the little buttons do have the strings on them.  (I have no idea why two of them have buttons and strings and the others don't.)  And, when they were shipped, the bags came just all tumbled together, and I had to come back to the website to re-read how to rejuvenate them.  That’s by putting them in the sun for a couple of hours every month or so.  I live in southern California, so that’s a viable option for me, but I wonder a little bit about folks who live in rainy or snowy climates during the winter.  It might make sense to offer a low-heat oven option also, if there is one.  I’ve rejuvenated them once, by putting them in the sun for the afternoon, and although I wasn’t really sure if they had stopped working, they definitely seem to still be working.  And I’m about to do it again, after a second month.  I’ll come back an update my review if they seem to stop working at some point.<br /><br />All-in-all, though, these Nature Fresh charcoal bags seem to do what they claim to do.  And although it would have been nice to receive some hooks or something to hang them with, the product webpage doesn’t say any hooks are included.  In fact, most of the pictures show them being used without hooks, so I’m not going to take any stars off for that.  (If I could do half-stars, I might have taken a half-star off…but it’s not worth a whole star.)  Finally, please note that I received these bags for free from Amazon’s Vine Voice program, in exchange for my honest review.
