Help Smick negative ion health board inhale moisture in humid environment, exhale moisture in dry climate and automatically adjust indoor air humidity.
This breathing process is an important factor to ensure that Smick negative ion health board can release a large number of negative ions continuously and persistently.
(Principle of negative ions released by health board: simulating the adsorption and accumulation of air charges by tree leaves, leading to the discharge at the tips of branches and leaves, and ionizing the moisture in the air to generate negative ions) 1 120 yuan barrel, 12 liter barrel.
