It includes the steps of implementation, where the mechanical valve in question (3), the range of movement of air inside the ventilation apparatus (100) by directing it to provide a first operating mode and a second operating mode 15 It has been adapted to; the first operating mode in question is from the air intake (1) The incoming air is filtered only by the odor filter (4) and from the first air outlets (2) for expulsion and the second operating mode in question, the air entering from the air inlet (1) with only the biocidal filter (6) or with both the biocidal filter (6) and the odor filter It is presented to be filtered by (4) and discharged through the second air outlets (5). 20 14. This is the method presented in accordance with claim 13; - also the presentation of a range hood (200) which includes a first control device, - checking the working condition of the fan (8) with the first control device and If the fan (8) is started while it is stopped, the mechanical valve (3) will be in its second operating mode 25 setting to the first operating mode and filtering related to the first operating mode If the first operation is performed or stopped while the fan (8) is running switching from the first operating mode to the second operating mode and regarding the second operating mode Generating a control signal to perform the filtering, and - Repeat step 2 if there is a change in the fan's operating status. 30 It includes the steps.

15. The method presented in accordance with claim 13 or 14, and also; - also at least one sensor and a control signal relating to the data received from that sensor. 35 of a range hood (200) which contains a second control device to produce presentation, - the condition of the air in the environment where the hood (200) is located with the sensor in question detection, - the level of harmful molecules found in the ambient air and cooking vapors If detected above a predetermined level, then the issue is... the sensor transmits this data to the second control device, and the second control device then transmits this data to the second control device. It generates a control signal related to the data, and - switching the mechanical valve (3) from the second operating mode to the first operating mode and It includes the steps for performing filtering related to the first operating mode.

16. The method presented according to claim 15, and also; 10 - the level of harmful molecules found in the ambient air and cooking vapors If it is detected below a predetermined level, then the issue is... the sensor transmits this data to the second control device, and the second control device receives this data. generating a control signal related to the data, - switching the mechanical valve (3) from the first operating mode to the second operating mode and 15 It includes the steps for performing filtering related to the second operating mode.
