Don't know what country you live in or if in the USA, but do you have
fans to circulate the air?
Can you have her stay at someone's home while it is being aired out?

Have heard if you have a vanilla extract put in a bowl in the room
where the paint was, it can help with the smell. About a tablespoon or
two. in bowl or saucer.

To me, an air purifier would help.
I don't like seeing the house was built hastily, in one month.
May be other problems with the house building., Could she have the
asthma from what the house was built with? Materials used?
Maybe some others on this newsgroup can help with suggestions.

G'day, Evgenij, I regularly examine these kinds of circumstances and
although it may commonly be paint fumes, it is more often associated
with things like flooring adhesives and most especially carpets or
associated materials.
The worst problems are often caused by foam rubber carpet underlays as
against foam plastic.
This problem will often still be apparent up to twelve months later.
If it were my child there is no way I would allow her to live in that
environment full stop....
You can appreciate the worsening effect created by a sufferer with
constant exposure to these kinds of problems, sensitivity keeps
increasing, problem worsens for the sufferer, in the end only the
slightest presence of any typical fume will have adverse effect..
I would strongly advise biting the bullet and keeping the child
completely away from that environment, any filtering will be assistive
but once a sensitivity is present which is obviously the case, will
really be pretty useless.
By the way children with these kinds of problems learning Buteyko
principles usually respond well.
Cheers, Merlin.
