This advice on how to build a smokeless fire pit is for you if you love backyard DIY and want a nice weekend challenge. 

Even the best fire pits typically produce a lot of smoke, which isn't ideal in several ways. Fire pit smoke is a significant source of outdoor air pollution. It also will stink out your clothes and make you cough, so reducing the amount of smoke your fire pit produces is definitely a good idea. 

As it turns out, a smokeless fire pit is well within reach anyone who likes making things – and will hardly cost you anything.

Full disclaimer: smokeless fire pits aren't actually 100 percent smokeless. It isn't possible to eliminate all smoke if your burning medium is wood. However, the construction of a smokeless fire pit allows it to burn hotter and more efficiently, which produces less smoke. 

Smoke is a byproduct of incomplete combustion. Complete combustion of wood produces only carbon dioxide and water. Incomplete combustion, when there is insufficient supply of oxygen, produces carbon monoxide, soot, and carbon dioxide. Needless to say, incomplete combustion creates ait pollution, which is bad for our health and for the environment. 

Smokeless fire pits use a double-wall construction with added ventilation, which creates the right conditions for near-complete combustion, with ash collecting at the bottom of the firepit instead of sooty smoke being released into the air. This won't be a perfect process, but it's close enough for residential fire pit burning.   

The most popular smokeless firepits right now are made by Solo Stove, and you can buy them on Wayfair (opens in new tab) and lots of other places.

As it happens, the design isn't very complicated and you can make one if you have decent DIY skills and a few hours to spend making it. If you know your way with a drill, this project is for you. 

You'll find doing this easier if you pre-mark where your holes should be with a marker or pen – space them out about half an inch. Use 1/4 inch bit for the holes. 

Your smaller stock pot will need to fit inside the larger one, so you'll need to remove its handles. This won't be as simple as unscrewing them because typically stock pots have riveted handles. You can cut them off with an angle grinder. Do this carefully as you don't want to cut through the pot itself.

Now use your 1/4 inch drill bit, drill holes throughout the base of your smaller pot, and some along the top. You don't need as many as in the perimeter of your larger pot, but you do need a few, as this will ensure the air circulates correctly in your fire pit.

To ensure a snug fit, measure the dimater of your smaller pot and cut a hole in the larger pot's lid that is the same diameter. This means that you won't get heat escaping from the sides of your fire pit while you're using it. When you want to clean the ash from your fiirepit, you'll just lift the lid and the smaller pot will come out easily. 

The best way to dirll the hole through the lid is by drilling lots of small holes right next to each other, until the center just pops out, a bit like the top of a can. 

Voila, your firepit is ready to use. 

If you already have taken advantage of fire pit ideas and have a fire pit – a brick one, say, you can drastically reduce the amount of smoke it produces with a few simple tricks. Lenny Brickowsy, an ACHP-certified handyman from Cleveland and a consultant at Juliei Salone (opens in new tab) , recommends the following:

Brickowsy also has a hack for making a brick or paver firepit smokeless by inserting a fire ring into it. You can buy a fire ring from Amazon (opens in new tab) , or you can use something like an old cake tin. 

Now, 'drill holes into the fire ring around the top and bottom rates at least a few inches in diameter. This is where cold air is going to enter the fire ring and keep the fire burning. Make sure you remove enough pavers so that the fire gets adequate air.'

Yes! Fred Hoffman, professional camper and chief Editor at The True Wilderness (opens in new tab) , says that 'even though the smoke will be less visible, the wood will still release its natural oils and scent.' You don't have to compromise on the quality of air around you to enjoy the magic that is a burning fire pit. Make yours smokeless and you get to enjoy all the benefits without that annoying and polluting smoke.
