Hi all,

I moved into an old apartment last week.

Something in the apartment is irritating my throat.

I started by hoovering and washing everything to see if it was dust. There was no significant improvement so the probable culprit is mold(?) I took some things apart yesterday to try to find signs but there is nothing, so I am now thinking this issue could be out of sight i.e it could be behind the walls.

I will buy an air filter as an interim solution and hope that this might improve things but I would like to get to the underlying cause. Does anyone know of companies in Zurich that would visit my apartment and assess this issue?

Thanks in advance for any help.
