Apostrophe's'

Hi,
1.The astronauts out the cleaning in between their main duties;they clean the meal area, change the air purification system's filters, collect the rubbish.

No, because it's the genetive form of system. These are the filters of the system - System's filters It's just like: This is the book of Jenny - Jenny's book

Yes, that's fine.

It's the same as saying 'The bathroom door'' rather than 'The bathroom's door'.'

Thanks, Mister Micawber.

Is the '...air purification system's filters...' non-native as well?Does 'non-native' mean incorrect?

The form is possible but sounds odd in simple, common collocations. Here with the longer noun phrase ('air purification system') it sounds acceptable.
