I have had no issues with durability or functionality. I can definitely feel the difference with no draft coming in being that is by my couch. The material seemed of thicker durability. And inflate to the right size to keep a good air seal. Review: Good quality - Has done a great job stopping the draft in my uncapped fire place. Is deflating some and seems like I will have to reinflate a little more frequently than expected. ## Features - The 21×10 Chimney Balloon plugs a rectangular chimney flue that is between 17”x7” to 21”x10”. The handle valve is 7” long. Every Chimney Balloon draft stopper includes a two-foot-long inflation tube. - IMPORTANT - The Chimney Balloon chimney plug CANNOT BE USED in an active GAS LOG SET. For safety, a GAS LOG set would need to be DISABLED or REMOVED in order to use the Chimney Balloon fireplace plug. - WINTER - The Chimney Balloon fireplace draft stopper blocks cold fireplace drafts and smells from a chimney. Stops heat loss by acting as a chimney plug draft stopper that air seals and insulates. - SUMMER - In warmer weather the Chimney Balloon Chimney Pillow flue hole cover stops smoky odors, drafts, noise or debris from entering the home. - DIY - You can inflate the Chimney Balloon fireplace draft blocker by mouth or with an air bed pump. The fireplace balloon is easily deflated and removed when you are ready to use your fireplace. - The Chimney Balloon chimney blocker creates a chimney seal that prevents the fireplace from snorkeling in outside pollution, roof heat, and smoke from wildfires. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CJJPHPBB | | Best Sellers Rank | #200,305 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #198 in Fireplace & Stove Accessories | | Brand | THE CHIMNEY BALLOON | | Brand Name | THE CHIMNEY BALLOON | | Color | White | | Customer Reviews | 3.8 out of 5 stars 55 Reviews | | Global Trade Identification Number | 00852586007597 | | Item Type Name | Chimney Pillow | | Manufacturer | Chimney Balloon | | Manufacturer Part Number | CBM21X10 | | Material | Inflatable Fabric | | Material Type | Inflatable Fabric | | Maximum Gap Fill | 21 Inches | | Model Number | CBM21X10 | | Unit Count | 1.0 Count | ## Images ![Chimney Balloon 21x10 Max 2-Ply Inflatable Chimney Pillow Fireplace Draft Stopper, Fireplace Cold Air Blocker, Works Better Than a Chimney Flue Cover Plate Damper as a Fireplace Blocker - Image 1](https://m.media-amazon.com/images/I/417awJHgipL.jpg) ![Chimney Balloon 21x10 Max 2-Ply Inflatable Chimney Pillow Fireplace Draft Stopper, Fireplace Cold Air Blocker, Works Better Than a Chimney Flue Cover Plate Damper as a Fireplace Blocker - Image 2](https://m.media-amazon.com/images/I/61iX+GSsKsL.jpg) ![Chimney Balloon 21x10 Max 2-Ply Inflatable Chimney Pillow Fireplace Draft Stopper, Fireplace Cold Air Blocker, Works Better Than a Chimney Flue Cover Plate Damper as a Fireplace Blocker - Image 3](https://m.media-amazon.com/images/I/41WUaxllivL.jpg) ![Chimney Balloon 21x10 Max 2-Ply Inflatable Chimney Pillow Fireplace Draft Stopper, Fireplace Cold Air Blocker, Works Better Than a Chimney Flue Cover Plate Damper as a Fireplace Blocker - Image 4](https://m.media-amazon.com/images/I/519swAOktnL.jpg) ![Chimney Balloon 21x10 Max 2-Ply Inflatable Chimney Pillow Fireplace Draft Stopper, Fireplace Cold Air Blocker, Works Better Than a Chimney Flue Cover Plate Damper as a Fireplace Blocker - Image 5](https://m.media-amazon.com/images/I/41VfJbbBgwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good to stop that winter wind and helps keep that warm heat inside your living area *by S***N on January 30, 2026* The insulation was a breeze if fit right up the chimney flute was pretty easy to inflate with the air mattress inflatable.
