Does Levoit Air Purifier Emit Ozone?

Understanding Ozone

Ozone (O3) is a molecule composed of three oxygen atoms, often lauded for its ability to neutralize pollutants and odors. 

However, at ground level, ozone is a lung irritant that can cause adverse health effects, particularly in individuals with respiratory issues.

Levoit Air Purifiers and Ozone Emission

Levoit air purifiers are designed with a focus on safety and health standards. The majority of Levoit models use True HEPA filters and activated carbon filters, which do not produce ozone. 

These filters mechanically capture particles and gases without any chemical reactions that might generate ozone.

Key Points:

  • HEPA Filters: High-Efficiency Particulate Air (HEPA) filters in Levoit air purifiers capture pollutants mechanically. This process does not involve ionization or any other ozone-generating methods.
  • Activated Carbon Filters: These filters absorb gases and odors. Like HEPA filters, they function without emitting ozone.
  • No Ionizers or UV-C Lights: Unlike some air purifiers, standard Levoit models do not incorporate ionizers or UV-C lights – both known for ozone generation.

Independent Testing and Certifications

Levoit air purifiers undergo rigorous testing and often receive certifications from organizations like the California Air Resources Board (CARB), which has strict standards regarding ozone emissions.

Certifications Include:

  • CARB Certification: Ensures that the air purifier meets strict ozone emissions limits set by this California-based environmental agency.
  • Energy Star Certification: Focuses on energy efficiency but also considers environmental safety standards, including ozone emissions.

Practical Usage and Recommendations

For users of Levoit air purifiers, the risk of ozone emission is negligible. However, it’s important to use these devices as per the manufacturer’s guidelines. Regular filter changes and maintenance are crucial for optimal performance and safety.


Levoit air purifiers, known for their efficiency in improving indoor air quality, do not emit ozone. Thanks to their mechanical filtration systems and adherence to strict environmental standards, they offer a safe solution for air purification. 

Consumers can rely on these devices for cleaner air without the concern of ozone-related health risks.
