What do people place on their platter for dust protection


Just wanted to hit everyone up for some responses. I'm tired of worrying about taking my pristine VM cleaned vinyl on a platter thats been idle for a week. I have a TT in which a dustcover woukd be inpractable. I hadnt googled for it yet. I just wanted to ask here. Plus I'm recovering from surgery and have some extra time.

Whatever happened to air purifiers? However many it takes. There’s no reason to have dust in the room to begin with. 
I use a Michell Engineering GyroDec (full plinth version, not the SE) and always keep the lid closed when not in use or playing an LP. I have no problems with dust accumulation on the platter. I just dust the lid about once a month.
@geoffkait But if you switch off the purifier to listen, some cells escape and land.
An old 1960’s comedy record works for me.  No plans on ever playing it again.
