When it comes to using an air ionizer in a room with high humidity, I would advise against it. Moisture can cause the device to malfunction, and the carbon filters may not work as efficiently. It is also important to note that air ionizers release negatively charged particles that attach to positively charged particles in the room. Today's air ionizers are often equipped with ozone sensors that help to control, suppress and prevent high levels of ozone from escaping into the air you breathe.
However, conflicting data related to the ionizer still persists, so I usually keep the ionizer option turned off. That said, in my experience, the vast majority of air purifying power comes from the unit's airflow and the HEPA filter. HEPA purifiers have been around for decades and have proven their effectiveness in purifying the air without adjusting the chemistry of the air. To prevent second or third hand smoke, I recommend leaving the ionizer on for only 30 to 40 minutes when there is no one in the room, and then turning it off before anyone enters. In conclusion, it is best to avoid using an air ionizer in a room with high humidity.
The HEPA filter is a much more reliable and effective way to purify the air without risking any malfunctions or ozone leakage.
