I have been getting totally sick of my Linn wool mat picking up and holding onto dust. I have been light vacuuming it occasionally, but still a pain.
It finally occurred to me that I could just take it off and put it on an enclosed shelf, away from dust, between uses. When I use it, I also just give the platter a quick wipe with a damp rag.
When I had cats I decided turntable lids make great cat perches, well actually the cats did. Plus the last time I left a lid off several decades ago, I came back to discover a snoozing kitten on the platter of my Focus One. Fortunately, the kitten, turntable, arm and cartridge were all fine.
I must admit to abandoning the felt mat in favour of a cork mat. Even with the lid, simply playing records caused a dust issue. Yes, I do clean my records. In winter especially (Canada) static electricity attracts a lot of dust.
Sounds like you have a humidity problem. I’m in the NE US and added a whole-house humidifier for a range of reasons (not because of vinyl!). Can use the felt mat year round.

That sounds like a solution to our very low humidity when the furnace runs in winter. We have tried room humidifiers with only moderate effect.

As others have remarked, I also keep the lid on my LP12 when not in use and have experienced no great problems with dirt/dust . Inevitably though, some dust and specks of dirt accrue but I find these are easily dealt with by removing the mat and giving it a gentle vacuuming as you do.
One thing you should not do is to wash it. I found this out to my cost many years ago with the result that the mat shrank considerably and had to be replaced!
