It's generally considered safe to sleep with an ionizer turned on. Using an air purifying device while you sleep can help minimize allergies and promote restful sleep. However, there is speculation that ozone released by ionizers may be harmful to health, and you may want to limit your exposure to it. If you want to enjoy better air quality, running the air purifier at night is highly recommended.

Contaminants and allergens are still present during the night, so the ideal is to filter them from the air continuously. While purifiers may not have an immediate impact on your overall health, as they are designed to remove contaminants and allergens, air purifiers can help make the air in your home much safer to breathe.

Today's air ionizers are often equipped with ozone sensors that help to control, suppress and prevent high levels of ozone from leaking into the air you breathe. Ionizer air purifiers are generally safe because the ionizers aren't energized enough to be harmful to your health. Some studies suggest that people with seasonal affective disorder (SAD) might benefit from using an ionizer in their home.I recently bought an ionized air ) purifier with a HEPA filter and it has started to produce a sweet smell, almost like that of baked goods.

Conclusion: Is It Safe To Sleep With An Ionizer On?
