Ionizers are not recommended for use in enclosed spaces when someone is present. It is best to open a window or operate the ionizer when no one is home, and then turn it off when someone is in the room with it. Continuous or high-level use of zonal room ionizers can cause serious health risks. Ion generators work by charging particles in a room so that they are attracted to walls, floors, tables, curtains, occupants, etc.
This can cause abrasion and the particles to be resuspended in the air. Some ionizers contain a collector to draw charged particles back to the unit. However, no controlled study has confirmed that these devices provide any benefit by rectifying a hypothetical ion imbalance.A fan-based ionizer is a better option for cleaning up quickly. The fan also promotes good ventilation, although it tends to be noisier and consumes more energy than a fanless ionizer.When using an ionizer, it is important to be aware of the potential health risks and take necessary precautions.
It is best to use an ionizer only when no one is present in the room and to ensure that the device is turned off when someone enters the room.
