@lalitk ”While you can’t eliminate 100% dust particles, using a high MPR 1900 and MERV 13 rated filters in your AC / Furnace system will help pull and capture most of the air borne microparticles.”
Already on it - have been using those for years. Still have dust in my listening room, but Winex in-room filter helps.
As for a switching power supply for turntable light… that punched my obsession buttons also, but was too embarrassed to admit it. I currently have zero switching supplies on my sound system circuit, and immediately thought I would have to add another lps if I got one of those lights - LOL
