How do I get rid of and prevent sigarette smoke in my room?

You cant get it out, it is the oil in the smoke and it will get into the wood.

If smoke can come up from downstairs from your floor, your building is fucking low standard, and is not worth saving.

There is no other way the smoke inside the room is from anywhere other than inside the room. Unless both have windows directly above, and both are open all the time to allow the smoke to go in from the outside.

Once the oil takes hold in the walls etc it will be impossible to mask it with any amount of plants. Perhaps with industrial sized air filters, maybe can mask it while it is on, but it won't get rid of it.

Wooden walls<--just replace the walls.

If renting, talk to your landlord, and bring up anything in the contract about smoke / non-smoking areas. If owning, scrub everything down with soapy water, dry, then fumigate with ozone. What kind of floors does your building have? OSB on wooden beams could let smoke through, but poured concrete wouldn't without openings. Check carefully for utility openings like electrical, data, plumbing, etc. Smoke might pass through a light opening on the ceiling below, work its way through the walls, and enter your room through an electrical outlet.

Thanks. I really hope you're wrong in that theres absolutely no way of washing it out, but I have little reason to doubt you.

But the smoke coming from downstairs doesn't come through the solid floor planks themselves but I'd guess through the numerous tiny gaps between planks and behind skirting. I hope lacquer and some other filling material can do the job.

I'm not replacing the walls, I'm sure I'd never be allowed to. If it has to come to that I'll just move out as soon as I can, but I'd prefer not to.

Thanks, I'll keep all those gaps and openings in mind. It's a wooden building I'm quite sure, as is usual here. But the building seems to be very old.

Fumigation with ozone, I did not know this was a thing. But I think I can't take such drastic measures here, I live with 3 others in an apartment.

If it's an old building with gaps everywhere, you won't be sealing it with lacquer. You'd need to install an airtight barrier across all routes the smoke might take to enter the room.

Ozone burns out the smelly chemicals left by smoke, and it infiltrates into materials like the smoke did. It's used for professional de-odorizing after fires and such. It's the most effective treatment available, but effectiveness takes several hours at a lethal ozone concentration. If the room were airtight, the other tenants wouldn't be a concern, but that's apparently the whole problem. There are also specialized soaps you might use, and specialized odor-blocking paint that goes over the cleaned surfaces, but with gaps remaining, that won't actually block lingering smells and new smoke from entering.

often the coffee stuff that remains after making coffee, that nasty wet stuff will be able to at least undermine other smells.

You're of great help, thanks a lot.
