Inspect the chamber and look for water stains

If there is a water stain:

1) Find and fix the source of the leakage

2) Inspect the room by checking the walls and corners, especially vulnerable spots for mold contamination. (Where to look?)

3) If any trace of the mold is discovered, treat it carefully. Make sure you know how to treat the mold contamination safely or get professional help.

If there is no visible stain:

1) Inspect the room by checking the walls and corners, especially vulnerable spots for mold contamination. (Where to look?)

2) If any trace of the mold discovered, treat it carefully. Make sure you know how to treat the mold contamination safely or get professional help.

3) Try to improve the ventilation in the room.

Consider:

• Inspecting / fixing possible source of vapor (like air leakage from kitchen or bathroom ducts)
• Leaving doors or windows open
• Turning on / installing an exhaust fan
• Setting up a dehumidifier or putting a desiccant dehumidifier
• Keep an eye on the trend of changes in the graph section of the application to see if the effort was effective.
