You ventilate to remove the extra indoor produced humidity and to exchange
it for new air with lower humidity and lower levels of carbon dioxide.
By comparing the amount of damp in the in- and outdoor air, you can
see if it is normal.
If the indoor air is abnormally damp you need to look for the source
of the damp, which can be due to a construction fault or a leaking plumbing,
alternatively not good enough ventilation.
Fungus is detected by bad smell, discolouring of surfaces, sagging floors
and rich occurrence of insects (silverfish, wood louse, spiders, mites
and others). To prove hidden occurrence of fungus, a fungal analysis
is necessary. Remaining smell after water damages is prevalent. Therefore
a smell sanitizing is often done. You get rid of much of the smell by
airing and increased ventilation. However, the ozone aggregates an effective
utility.
Ozone is a toxic oxygen compound that reacts with organic compounds.
Odorants in the air you breathe is oxidized –annihilated.
High humidity is a prerequisite for the Real House Fungus to establish
itself. Damp damages can arise as a result of many causes, e.g. unventilated
crawl spaces, wrongly insulated houses or as a result of a water damage
that have not been taken care of in the right way.
