Everyone knows that marital difficulties boil down to one thing: husbands farting in bed. Thank goodness, then, for this wonderful item – a duvet containing a carbon filter, to remove all the noxious gases emitting from his behind!
(If anyone knows whether or not this is a real product, do let us know.)

Wow. Well, they do have a website that looks real: https://www.bettermarriageblanket.com/. But it is tough to believe anyway. I have trouble getting past the idea that they use military-grade chemical weapons protection.
Lol!! I don’t think it’s real. They make some pretty outrageous claims for $29.95. I think it’s just a joke, but it’s a good joke.
It’s real, but won’t work. For a undergrad chem project I analyzed the “scent-lock” hunting clothes (they are supposed to work the same way. (I went to school in Alaska if that explains the odd project – another one involved bioactive compounds in AK blueberries).
The carbon is not like a thin film, it’s more like little chunks randomly distributed (lots of spaces for “gas” to get through), and you cannot recharge it in a dryer. To recharge carbon charcoal you would have to bring it up to temps that would cause the rest of the garment/blanket to burst into flames.
Sorry if any of you were counting on this new technology, it’s a gimmick.
