The filter apparatus includes a delivery device, which is provided in addition to a ventilation system of the motor vehicle and can be operated independently of the ventilation system for drawing in and delivering air from the interior of the motor vehicle. The filter apparatus includes at least one filter element, through which can flow the air drawn in and delivered by the delivery device for filtering the air. The filter apparatus includes at least one outlet for introducing the air filtered by way of the filter element into the interior. The filter apparatus is designed to wirelessly receive at least one signal emitted by a terminal and to activate the delivery device based on the signal. ## Claims ### Claim 1 A filter apparatus for a motor vehicle, comprising: a delivery device, which is operable independently of a ventilation system of the motor vehicle and is provided in addition to the ventilation system in order to draw in and deliver air from a passenger compartment of the motor vehicle; at least one filter element through which air which is drawn in and delivered by way of the delivery device flows and filters the air; and at least one outlet for introducing the air filtered by way of the filter element into the passenger compartment, wherein the filter apparatus is configured to receive wirelessly at least one signal which is made available by a terminal and to activate the delivery device as a function of the signal. ### Claim 2 (depends on 1) The filter apparatus according to claim 1, wherein the filter apparatus includes at least one ionizer for ionizing the air which is drawn in and delivered by way of the delivery device. ### Claim 3 (depends on 1) The filter apparatus according to claim 1, wherein the filter apparatus includes an electronic computer device with a memory in which data characterizing a time can be stored, and the computer device is configured to activate the delivery device automatically at the time as a function of the stored data. ### Claim 4 (depends on 2) The filter apparatus according to claim 2, wherein the filter apparatus includes an electronic computer device with a memory in which data characterizing a time can be stored, and the computer device is configured to activate the delivery device automatically at the time as a function of the stored data. ### Claim 5 (depends on 1) The filter apparatus according to claim 1, wherein the filter apparatus includes an electronic computer device with a memory in which data characterizing a time can be stored, and the computer device is configured to deactivate the delivery device automatically at the time as a function of the stored data. ### Claim 6 (depends on 2) The filter apparatus according to claim 2, wherein the filter apparatus includes an electronic computer device with a memory in which data characterizing a time can be stored, and the computer device is configured to deactivate the delivery device automatically at the time as a function of the stored data. ### Claim 7 (depends on 3) The filter apparatus according to claim 3, wherein the signal characterizes the time, and the computer device is configured to store the data in the memory as a function of the signal. ### Claim 8 (depends on 5) The filter apparatus according to claim 5, wherein the signal characterizes the time, and the computer device is configured to store the data in the memory as a function of the signal. ### Claim 9 (depends on 1) The filter apparatus according to claim 1, wherein the filter apparatus is configured to draw in air from the passenger compartment and discharge the air to surroundings of the motor vehicle by way of the delivery device. ### Claim 10 (depends on 2) The filter apparatus according to claim 2, wherein the filter apparatus is configured to draw in air from the passenger compartment and discharge the air to surroundings of the motor vehicle by way of the delivery device. ### Claim 11 A filter apparatus for a motor vehicle, comprising: a delivery device which is operable independently of a ventilation system of the motor vehicle and is provided in addition to the ventilation system in order to draw in and deliver air from a passenger compartment of the motor vehicle; at least one filter element through which air which is drawn in and delivered by way of the delivery device flows and filters the air; and at least one outlet for introducing the air filtered by way of the filter element into the passenger compartment, wherein an electronic computer device is provided with a memory and is configured to store data, which characterize at least one time, to store in the memory and to activate and/or to deactivate the delivery device automatically as a function of the stored data. ### Claim 12 (depends on 11) The filter apparatus according to claim 11, wherein the electronic computer device is configured to detect times at which the motor vehicle and/or the filter apparatus are/is brought into operation, to store the data which characterize the detected times and to activate the delivery device as a function of the stored data. ### Claim 13 A method for operating a filter apparatus for a motor vehicle, the method comprising the acts of: operating a delivery device of the filter apparatus independently of a ventilation system of the motor vehicle; drawing in air from a passenger compartment of the motor vehicle by way of the delivery device; delivering the air through at least one filter element, by way of which the air is filtered; and introducing the filtered air into the passenger compartment via at least one outlet of the filter apparatus, wherein by way of the filter apparatus, at least one signal which is made available by a mobile terminal is wirelessly received and the delivery device is activated as a function of the signal. ### Claim 14 A method for operating a filter apparatus for a motor vehicle, the method comprising the acts of: operating a delivery device of the filter apparatus independently of a ventilation system of the motor vehicle; drawing in air from a passenger compartment of the motor vehicle by way of the delivery device; delivering the air through at least one filter element, by way of which the air is filtered; and introducing the filtered air into the passenger compartment via at least one outlet of the filter apparatus, wherein by way of an electronic computer device having a memory, data which characterize at least one time are stored in the memory, and the delivery device is automatically activated and/or deactivated as a function of the stored data.
