Abstract

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.
