Can BBQ smoke be a problem for CPAP?

I am living in a small cottage in the backyard of my landlord's house. Just a few days ago, my landlord got a new BBQ stove and he has been having a BBQ feast everyday. Whenever he does that, the smell gets into my cottage. While it is not an intense smell (the stove is 10 meters from my house), I am afraid that it will somehow deposit in my CPAP machine and cause permanent odor (like tobacco's smoke). I could close the window when he grills stuff, but sometimes he grills before I come home and, per his request, I usually leave my window open when I'm away. I wonder if anyone has a similar experience and notice it affects the CPAP? I don't want to make a lot of fuss with the landlord if it will not pose any problem, but at the same time I don't want to have to replace my new S9 autoset just because there's an unremovable smell Thanks for any advices

Get a cover for your cpap machine, just a small plastic bin would work.
Add one of those charcoal based smell absorbers to the bin (NOT one of the febreze toxic thingies).

(Remove cover before using)

It may be worthwhile to ask if he would mind if you close the windows now that he is using the BBQ stove to avoid the smoke odors from effecting clothing and other items inside.

Change the filter often. If the smell gets into the machine it will linger for a long time after.

One issue with BBQ and other cooking smoke is that it contains fats and oils. These tend to deposit on stuff and you can smell it for a long time.

If they get into your machine and deposit in the internal sensors, this might cause problems.

So, follow the advice already given and cover your machine with something that will block the smoke completely. Close the windows when you are away and explain your landlord your concerns about damaging your machine as the motivation for closing them.

Try to make perfectly clear that these measures will be sufficient and you are NOT asking him to stop his BBQ actvities. No need to put your arrangement at risk.

It's not just about your machine smelling bad - smoke of any kind is bad for you!

Don't forget to point out that the smoke can get into curtians, furniture, even permeate the walls. Just tell him your concerns about the cpap machine, and the maintenance costs of the cottage
