There's work involved in using CO to ctb. You need to find a suitable small space, like a small room, a car, or a tent. Any potential points of leakage should be sealed up. Charcoal needs to be lit elsewhere, preferably outside, and allowed to burn until it's glowing red hot and no longer emitting smoke. Then it is brought into your chosen space and time (without you present) is given to allow the CO being produced by the hot charcoal to fill the space. After some time elapses, then you enter the room and take several deep breaths.
For CO to be the most peaceful, CO levels should be very, very high. The truly only way to know how high they are is by using a CO analyzer (about $300 US) capable of measuring CO levels up to 10000 parts-per-million (ppm). A good quality charcoal should be used, one that is 100% carbon and preferably "lump" composition. You'll need something to light the coals in (metal buckets) as well as something to place the hot containers on in your chosen space (bricks). It may be easier to get the charcoal going in chimney starters and then transfer them to metal buckets.
The amount of charcoal to use is governed by the equation of 0.135 kg/m³. You need to measure your chosen space's height, length, and width and multiple the 3 measurements together to obtain the volume of the room. If measuring in US Customary units, just convert over to SI units. Whatever volume you calculate for your space, just multiply it by 0.135 kg/m³ and that will give you the MINIMUM amount of charcoal in kg to use. Take that amount and at least triple it to be safe and make sure you are using enough. If you need the amount in pounds (lbs) just use an online converter.
