Q

A smell is what is not really.

A

The no smell of human waste will be carried out by its full decomposition. Although there is a fermentation smell, it is hardly worrisome with a case. Since the fan is travelling the interior of a room, in addition, it is comfortable. Since the deodorization effect is in the sawdust itself, when filth goes into a toilet bowl, there is not a bad smell. Moreover, since it is decomposed and disappears and sawdust becomes a compost, it is sanitary at no odor.
