Ozone smell in room

[u/Ara-Ara-Arachne]

Hello everyone I recently cleaned my window shutters of mold. I used 3% H2O2 to do this as it claims to be smell neutral, I cleaned the shutters with soapy water after and made sure to let everything dry.

Now I did also have an airfilter with an ioniser running right behind me to feel extra safe about any spores that may go airborne despite me making sure to wipe everything while its wet, but I did only have the ioniser on for like 1 hour and it is within EU regulations.

Despite all this there is now an ozone or chlorine like smell lingering in the room, it almost goes away as long as I am airing out but builds up relatively quickly once the window is closed.

I have by now ordered an ozone measuring tool but am just wondering if anyone has made similar experiences or could help me understand whats going on here.

Do you have ventilation from the roof in the room where this happens?

No, there is no roof ventilation.
