Electronic air cleaners do not remove:

Electronic air cleaners primarily function by utilizing electrical charges to attract and capture particles from the air, such as dust, dirt, and allergens, including airborne animal fur and carpet fibers. However, these devices are generally not effective at removing gases or odors.

Odors consist of gaseous compounds that do not have the mass necessary to be effectively captured by the particulate removal methods used in electronic air cleaners. While some advanced air purification systems may incorporate features capable of addressing odors through additional technologies like activated carbon filters, traditional electronic air cleaners focus on particulate matter and are unable to tackle the molecular structure of odors effectively. This is why the assertion that electronic air cleaners do not remove odors is accurate.
