Outdoor exhaust is very simple, as long as you find a suitable fan connected to the hose, you can exhaust moxa smoke to the outside. If you have poor hands-on ability, you can buy it directly online. Search: Moxibustion range hood, and a bunch will come out! Of course, this simple treatment method also has disadvantages, that is, it is easy to complain to people nearby by discharging smoke outdoors, so this direct and single smoke exhaust method is not recommended in general moxibustion halls.

The other is smoke filtration, and there are three kinds in the market: physical filtration, weak chemical reaction and high voltage static electricity.

Physical filtration, that is, filtering by using the filter layer, moxa smoke and taste are trapped on the filter layer, and the filter layer needs to be replaced constantly, so the use cost is high.

High-voltage static electricity utilizes the properties of electrodes to adsorb substances on moxa smoke. This material does not need a filter layer, but it needs a fixed period to clean the aluminum absorbed inside. At the same time, the taste filter is also made of activated carbon, and there are some consumables!

The last weak chemical reaction is that moxa smoke reacts with the corresponding solution, so no smoke will come out. The cigarette filter of the moxa stick box decomposes moxa smoke in still water, and the filter loss is very small!
