Why is it bad practice to use the same socket as the TV/radio? The manual states doing so may cause picture flutter or noise and says the purifier should be at least 3 ft away from a TV or radio. Why would this occur using an air purifier and what risks are there if it's not 3 feet away, or even beside one? I have just received my AirMax8L and currently it’s plugged into a power strip which also has my TV and a streaming device and is sitting roughly one foot from my TV as that’s the best place for it in terms of air flow. Thank you in advance for any answer I receive.
