While I've always used compressed gas cylinders to purge, there is a way to purge without them that most anyone can do.
Dry is the solid form of carbon dioxide. It is heavier than air. Specifically it has molar mass of 44.01 g/mol. Oxygen (O2) has a molar mass of 31.9988 or ~32 g/Mol (atomic mass of oxygen 15.9994 x 2).
Dry ice, compressed gas, even mixing baking soda and vinegar can make albeit less efficiently.
The most efficient and pure form comes from compressed gases, but dry ice is a lot easier to get your hands on and cheaper in most cases. Dry ice sublimes above -90F meaning it goes straight to gas instead of a liquid first.
The problem a prepper has is isolation of moisture from frost. Simply dropping a chunk in a bucket of wheat won't work.
Visualizing pouring the gas like a liquid helps. It's heavier than air, so a pie pan can work to catch the moisture while letting the gas push over the side into the bucket.
Food for thought.

I just read up on another use for it. Take a board and put a chunk of dry ice on it in the middle of your lawn. Comeback in a couple of hours and it will have attracted all the creepy crawly's in your yard. Then you can see what's hanging out in your lawn. Also used to attract bed bugs in you house. You can make a trap to lure them in for elimination. I might actually do this to see just how many ticks are in our house. I've been finding one a day whether I go in the yard or not. I check the dog before she comes in so it's not from her. Huh. Apparently, all kinds of uses. www.continentalcarbonic.com/dry-ice-uses.html

For those thinking about using it inside.
