WebWhen measuring ions indoors, remember that if the air is not moving, it is also not mixing well. This may lead to ion quantities that differ drastically from one area to another area in a room, even over a distance of a few cm. A more uniform ion density will result if the air in a room is moving, such as from a fan, so it will be well mixed.
