Description

A plasma indoor air purifier

technical field

The utility model relates to a plasma indoor air purifier, which belongs to the technical field of environmental protection.

Background technique

On the one hand, as the public pays more attention to the environment and health, the standards for indoor and outdoor air quality requirements are also rising.
