AC motors are the safest. Choose the lowest wattage that will do the job. Mechanical is better than electronic. If it has a clock or lit up display it will emit all the time it is plugged in. Unplug it when not being used, don't just switch off. Get a EM meter and check its earthed properly ie no field. Keep as far away from it as poss.
Bought the top model of bosch with wi-fi but even turning the wifi off didn't help anything so that machine is clearly the worst machine/device even at long distance I've ever used. Didnt know white goods could be that bad since I've never encountered it before. Maybe its the wifi module is causing the dirty ef?
The motor will and so will any low voltage digital electronics, clocks etc. They will not run on mains so will be transformed. Use a radio if you get a chance. See how far away you have to get to stop picking up MW signals. Choose the lowest RF producer as it will make less dirty electricity. Do not be near it when it is on. Go out. Women suffer from illnesses of modern civilisation 3 times as much as men because of poor kitchen design and cooking at peak dirty electricity times.
