What can I put in dd room that isn't a candle and won't get knocked over?

[2anddone]

Dd (13) enjoys having friends round in the holidays, they go to her room and chat, TikTok etc. When they leave her room always smells...a little bit sweaty I open a window during the day especially when I know they are coming but does anyone have any ideas what I could use to get rid of the smell?
I don't want to use candles for obvious reasons, Reed diffusers have a chance of being knocked over and I am not sure how over powering a plug in would be as her room is a box room!
Anybody got any ideas please or do I just shut the bedroom door and leave it?? Before anyone flames need I haven't mentioned anything to dd and I definitely don't want to discourage them coming round as would much rather they were here than hanging around in town!!

You can get small battery powered oil diffusers. The oil is dropped onto a fabric disc and there’s a small fan that wafts the smell. So even if it was knocked over, there's nothing to drip.

Neutradol gel comes in a little pot absorbs odours, they work brilliantly.

Seconded! They are great 👍

Any and all fragranced things are just papering over the existing smell. Ventilation and dehumidifying are what you should be looking at - perhaps there's a pipe/roof/window leak and a damp wall?

Car air fresheners work for a small room- either hanging ones or the yankee candle stick things

Pou pourri or dried flowers with fragrance/essential oils on

You could use a reed diffuser with only a small amount of liquid- it'll mostly be absorbed by the reeds

I second Neutradol. It sucks up the smells and just leaves a non headache inducing, subtle scent.

We have electric fragrance oil diffusers with colour changing LED lights that would look great in a teenagers bedroom. DD16 has one in hers, we've one in the lounge and I have a beautiful glass one in my bedroom, but probably too fragile for a room full of teens!

Second PP suggestion of a catalytic lamp. Amazing!!!
I have an Ashleigh & Burwood.
Lampe Berger are the originals!

Ds's room smells like a hamster cage. I open the window and light a candle when he's out and set a timer for 30 minutes so that I don't forget it. The combination of the two things is the only thing I've found that actually works, anything else just masks it.

Yankee do the fragrance spheres. I use cotton smell for the hot press. This and opening the windows regularly should help. As a previous poster stated, ventilation and lighting a neutral eg cotton candle every so often should help.
