Chimney Balloon CB33X12 Large Chimney Balloon, 33" x 12"

I little hard to install, needs a longer inflation tube. Does not fit well around the damper chain so there is some air leakage, but better then what it was before we installed it.

I had a nasty backdraft bringing soot smells into the house. I sealed the top of the chimney, which seemed to help but not enough. This balloon was the only thing that finally stopped the backdraft. Thank you!

Doesn’t stay inflated. Not worth the money. Worked great for about a day and then noticed that it wasn’t inflated fully anymore. Tried multiple times to keep it inflated with no success.

I purchase this balloon to cover my chimney but it did not work for me the balloon is round not perfectly seal and it does not stand by its own .its pricey I felt like wast of my money !

Our chimney doesn't have a damper, so this has been perfect for us. We've had to blow it back up once (the weather keeps going from hot to cold so it's lost the air pressure) but putting it in and blowing it up is super easy, so it's not big deal. It really does keep our house noticeably warmer! I wish we'd bought it a long time ago!!

This does work for us

Would not stay inflated ! Chimneys are not perfect environments for balloons and once it starts leaking good luck finding the cause . You'll end up looking like the chimney sweep from a Disney movie.
