Description

Technical Field

After the filter device has been used for a long time, the internal filter plate is easily blocked by impurities, resulting in slow air output and poor filtering effect. The existing filter device does not have a blockage alarm function, which results in the user being unable to replace the filter plate in time, thereby affecting the filtering effect. A fresh air system and a filter device are proposed. Utility Model Content
