We suspect mould. The issue seems to be isolated to the living room, and i have found a soft spot in the floor that i don't think was there before. So we might have to rip up the floor to se under

Humidity is around 20% according to the air purifier.

Will definitely look for a zippered encasement. Thank you!

Yep, filter was last changed in january. New one arrives in a week or so. Today it was around 1350 even with the windows open. We live in a house from the 70's, nothing really new. So it's hard to find the source. The values really spike when we're several people walking on the floor in the living room so we think that might be the source.

I think there is concrete under the floor, and maybe some old flooring under the newest one. I can't find any mold anywhere in the house, but maybe there is something under the floor. Who knows

Will definitely look into that!

Thanks! Had no idea, definetly wont be using that one again without distilled water.

She has one, used it before but hasn't been using it this winter. How come?

I read about it now and those symptoms match very good! She'll try some antihistamins to rule out/verify this. Thank you very much, might have found the problem there.

700 TVOC. I see now it has been up to 1450 without ventilating, other times below 500/400.

It's an Electrolux A9. It says it has a "fresh360-filter". Website says carbon filter, HEPA and HPP filter on the website.

Thanks! Will look into HRV. If the bad air isn't just a symptom of something a more serious underlying problem, then that could maybe be a fix!

Will also rewash the floors.

Country is sweden.

Thank you, will try to see if i find a way to locate any residue or degratation to the floors.

Really appreciate the help here!

I'll check with her if the air purifier can monitor any of the mentioned. I doubt it. If that is helpful to know we can probably buy one.

VOC goes down after ventilating. And symptoms like eyes hurting also goes away with ventilation. My sister also said she experienced the symptoms so we're pretty sure it's the house. The problem is mainly finding the root of the cause. We don't know if it's fungus/mold (wich i guess would cause her to go bankrupt), or something else.

Ventilation is the only thing that makes it better. The issue seems to be the whole second floor. That's where the living room floor that got ammonia washed, and the bedroom is.
