The herb vaporizer is basically a chamber that has a heating element, a heater coil, and some type of ventilation system in the bottom. In this case, the chamber is in direct contact with your weed, which means that the quality of the vapor that comes out of the device will be greatly reduced if the device does not heat the herb up properly.

So the way that a weed vaporizer works is by heating your herbs until you are able to smoke them.

One of the most important questions to ask when you are looking at how does it work is this: Does it use hot air or cold air? While some people prefer a bit of hot air when they are smoking their weed, others may prefer to have a cool mist misting device. This way your vapor will remain cool, but still have the flavor of the herb in it.

What else should you look at when you are looking at how does it work?

Is there a filter?

This is very important, because the first thing that goes into your vaporizer is the herb, and since this is going through the filter it will be getting filtered out as well. With a filter in place the herb will not get contaminated and go bad, and also will not go bad if it is not smoked right away.
