In common parlance, that means if you have a bed of healthy moss in your room, you will continue to enjoy a comfortable relative humidity of between 40 percent and 60 percent.
“We also know that influenza is most likely to spread when the humidity drops below 10 grams/cu. meter, so moss actually acts to stop that,” Kotake said.
In addition, moss acts as an air purifier. Instead of absorbing water and nutrients from the ground through a system of roots, moss sucks them in from the air around it.
“That means it actually collects unwanted particles from the air and stores them inside itself,” Kotake said.
