What is UL 779?

UL 779 is a standard developed by Underwriters Laboratories (UL), an independent safety science company, to certify the performance of air purifiers. This standard provides guidelines for evaluating the ability of air purifiers to remove airborne particles and gases from indoor air. It sets forth specific criteria that air purifiers must meet in order to receive the UL 779 certification.

Main parameters for UL 779 certification

The UL 779 certification evaluates air purifiers based on several key parameters:

Efficiency: The air purifier must be able to effectively remove a specified percentage of airborne particles, such as dust, pollen, and pet dander.

Airflow capacity: The air purifier must have sufficient airflow capacity to circulate the air in the room effectively.

Purification methods: Air purifiers may use different technologies, such as HEPA filters, activated carbon filters, or electrostatic precipitators, to capture and eliminate pollutants. The certification ensures that these purification methods are effective.

Ozone emission: The UL 779 standard restricts the amount of ozone emitted by air purifiers to protect human health.

Importance of UL 779 certification

UL 779 certification is essential in determining the effectiveness and safety of an air purifier. By choosing a certified product, consumers can have confidence that the air purifier will deliver the promised level of performance and meet certain safety standards.

In addition, many building codes and regulations require the use of UL 779 certified air purifiers in certain applications, such as hospitals, commercial buildings, and industrial facilities. This ensures that the air quality in these environments meets high standards and protects the health of occupants.

The future of UL 779

As technologies continue to advance, the UL 779 standard is constantly evolving to keep pace with the latest innovations in air purification. New parameters may be added, and existing ones may be updated to address emerging concerns and improve the effectiveness of air purifiers.

Furthermore, in response to growing public awareness of indoor air quality, UL 779 certification is expected to gain even more significance in the future. Consumers will likely become more conscious of the importance of choosing certified air purifiers to ensure the air they breathe at home or work is as clean and healthy as possible.
