Even in Japan, the number of "share houses" where several people live in a single house is increasing. However, the problem when sharing a house or room is the smell of the toilet. Immediately after someone has added something, the toilet is smelly and hesitates to use it. My family can still put up with it, but I can't put up with the smell of others.



In the United States, there is always a match in the toilets of share houses. It is believed that if you light the match after adding some extra work, the smell will disappear. But this strange custom is

"When I rubbed the match, the toilet exploded!"

It is said that there is almost no deodorant effect just by giving birth to the urban legend.


"Fresh Air Plus" is a toilet seat that solves the problem of toilet odor. A powerful fan is installed to inhale the scent. It is a mechanism that exhausts air to the outside via a hose attached to the toilet seat. Since the air is taken in near the source of the odor, it is possible to ventilate about 30 times faster than a normal ventilation fan installed on the ceiling.


"Fresh Air Plus" is easy to install. Simply remove the toilet seat in use, install the "Fresh Air Plus" in its place, and then drill a hole in the wall of the toilet. Pass the hose through it and the installation is complete.





Many of the houses used as share houses are old, so if you negotiate with the landlord, it is highly likely that they will allow you to install them.

You can't make a hole in the wall in an apartment or condominium. In such a case, the effect can be expected by simply pulling the tip of the hose out of the toilet window.


The "Fresh Air Plus" developer will soon start a funding project on kickstarter. It will be very interesting to see if there will be any investors.
