Air purifier

A filter device for ambient air filtration has a blower housing with air inlet and air outlet. A device for generating an air flow is arranged in the blower housing and generates an air flow in operation from air inlet to air outlet. A flexible air conducting hose is provided with a first open end connected to the air outlet of the blower housing and with a second closed end. The flexible air conducting hose has openings arranged between first open end and second closed end. Filter elements are arranged in the openings, respectively. The filter elements separate a raw side inside the air conducting hose from a clean side downstream of the filter element. The air conducting hose is inflated in operation of the device by the air flow. The flexible air conducting hose has a reduced air permeability compared to the air permeability of the filter elements.

Filter device, air conducting hose with filter element, tunnel, and use of the filter device

An ambient air purifying device has a blower housing with air inlet and air outlet. In the blower housing, a flow generating device is arranged generating an air flow from air inlet to air outlet. Between air inlet and air outlet, a filter device is arranged with filter elements arranged relative to each other in a V shape. The blower housing has a servicing door through which the blower housing interior is accessible. The filter device has a filter element support held at the blower housing and supporting the filter elements. The filter element support is pivotably supported about an axis at the blower housing. The filter element support is transferrable from an operating state, in which it is completely inside the blower housing, into a servicing state, in which it projects at least partially through the servicing door from the blower housing, by pivoting about the axis.
