Which EMC (electromagnetic compatibility) devices are helpful for the design and modification of home ventilators?

Home ventilator EMC prioritizes low noise and interference immunity. The turbine fan should use a low-electromagnetic-noise brushless DC motor (BLDC), and its driver should employ sinusoidal FOC control technology to reduce torque ripple and noise. A ferrite core can be added to the fan power cord. The pressure sensor signal conditioning circuit should be properly shielded and filtered. The main control board's switching power supply should be a low-noise model, and an input EMI filter may be added. A conductive coating can be applied to the inside of the device's plastic casing to reduce radiation, and the data card (SD card) slot should have ESD protection (ESD5V0L4).
