Adjustable Smoke Guard for 28.5" L x 48" W Fireplaces, Black Powder Coat Finish, 6" Height

I got a new-to-me house and the inspection said that our flue liner was undersized which was leading to smoke entering the room if a fire was lit. Chimney company wanted to charge $$$$ for a larger flue liner. Google told me I could try this- and I'm so glad I did! No more smoke enters the room with this installed. Took like 5min to setup.

This product works as advertised. For years we were unable to enjoy a fire without smoke exiting the fireplace. Apparently, the opening was too large for the flue and smoke would billow from the top of fireplace. By just reducing the opening by 4 inches, the issue has been completely resolved. No more smoke. Works perfectly!! Great product. Thanks.

Came with directions which I didn't need. Fits well nice and snug..

We recently had work done on our fireplace in our newly purchased, older home. Long story short, we ended up putting a stainless steel cylinder liner down our chimney to prevent further damage to the crumbling brick liner the chimney had. In doing so we went from having a large fireplace opening (into the living room) and a large flue opening (out the chimney top), to having a large fireplace opening into our living room and a SMALL flue opening out the top. Ideally, you want the opening up the chimney to be of a certain ratio to the opening to the room for proper smoke flow. Our new room to flue opening ratio meant that any smoke from a fire would now want to travel into our living room instead of out the top of the chimney like it’s supposed to. Enter this product, the HY-C Smoke Guard.The Smoke Guard does its job, effectively making our fireplace opening into our living room smaller, forcing the smoke upward thru the chimney instead of rolling out into our living room. The Smoke Guard installs like some shower curtains, using tension to hold itself up and in place without any mounting hardware needed. The instructions aren’t the easiest to understand, a criticism heard from other people that I can confirm. I was still able to install without issues. Our fireplace opening into our living room is smooth/level at the top and rough on the sides (from the bricks), so while it installed flush to the top of the opening, there were some small gaps on the sides of the Guard from the uneven-ness of the bricks. Luckily the product comes with a tube of silicon paste to seal any spots that need it. I’ve seen other people complain that it’s useless due to their uneven fireplace openings. I didn’t have that problem.Overall, I'm happy with the Smoke Guard. The difference of smoke rollback into our living room pre-Smoke Guard vs. post-Smoke Guard is NIGHT & DAY. This said, I purchased the 4" model, but I wish I had gone with the 6" model. I still have some occasional smoke roll back into the room, and I'm all but convinced that if I had the 6" model this wouldn't be the case. That's not a knock on the product, just a notion that it may be better to be aggressive on what size to buy as the bigger the Guard the more smoke held in. I was originally concerned that the bigger model would restrict our view of the fire, but I think most people would happily give up 2” of viewing area for even less smoke in your house. My lack of 5 stars stems from what was originally sent to me when I first ordered. I ordered the Guard in the flat black color, and was shipped the bronze color instead.My bottom line: Works great IF you have straight/level fireplace openings, buy bigger than you’re thinking to prevent any and all smoke rollback, & don’t be surprised if you’re shipped the wrong color.

This product saved my life. We live in a 100 yr old house and the cost of natural gas made our gas log cost prohibitive. I decided to burn wood one rainy day and almost immediately our house filled with hazardous smoke. We had a chimney sweep come out to clean things up and he pointed out that the arch top design of the fireplace was allowing smoke to spill out of the firebox and into the house. This is clearly evident by the soot on the keystone tile in the photo. I was going down the path of fabricating a panel to fit the not-so-standard curvature of the opening and stumbled upon the Smoke Guard solution. I had concerns about the fitment given that the product is square on the ends, but my concerns faded during the installation process. Yes, I had gaps on the sides, but they were not beyond the tolerance for the included sealant. After allowing the sealant to cure I started a fire to test the Smoke Guard’s effectiveness. It was a high stakes situation as the results would inform us as to whether or not we would ever be able to burn wood in our fireplace again. Boy am I happy with the results! Not one whiff of smoke in the house at all. I was also a bit concerned that the Smoke Guard would take away from the overall aesthetic of the fireplace, but in my opinion it really doesn’t. Besides, it is necessary for it to be used so the trade off is non negotiable. If you have a smoke problem with your fireplace, try the Smoke Guard!

We’ve lived in our house for 6 years (built in 1959). Every fall/winter we try to have a fire but it smokes up our whole house so we gave up. I’ve had fireplace professionals out to inspect it and “nothing is wrong, the chimney is clean.” After spending some time researching, I came across this product. I was very skeptical at first, sounded too good to be true. We’ve had this guard for about a week now and have had fires going all day long (12+ hours) and it works amazing! Our only issue is that the guard doesn’t stay in place very well with the way our brick is stacked. It’s siliconed in now so we’ll see how long it stays before falling again. It is still worth every penny though! Side note: I have an air purifier in the same room, the light turns red when the air qualify is bad, which it did previously when we tried to have fires without the guard. With the guard the light has stayed blue, which means the air is clean.

This fixed our smoke issue....the smoke would come out of the top of our fireplace from time to time....this product eliminated that issue and reduced the smell as well....WIN!

worked perfectly. it should come with more backing insulation, and a stronger more heat resistance sealant, but other then that, no more smoke! so its great
