UL Certified: What Does It Mean?

Want to know what does it mean by UL Certified? When you purchase an air purifier, you can find reassurance in seeing logos and certifications on the device’s box or package. However, not everyone knows what’s behind certain logos and certifications. 

In this article, we’d like to bring you behind the scenes the UL certification. What is it? And what does it mean?

UL Certified: What Does It Mean?

UL Certification: Where Does It Come From?

The UL refers to Underwriter Laboratories, which is a third-party certification company.

There is no general UL approval category, but products can be either UL certified, listed, recognized, classified, or performance verified. 

UL certifies products with the intent of making the world safer for consumers. They run safety tests on products that end up inside consumers’ houses.

They continually check products to ensure they meet standards and are constructed properly for the highest level of safety.

For example, UL testing can review whether a device can handle the proper amount of current and whether the wire size is correct.

Other than UL certified you could find another label: for example, you can find something like “UL listed.” What does it mean?

UL Listed: Meaning

The seal for UL-listed products is highly recognizable and features many consumer goods. It is highly recognizable because it’s a UL inside a black circle. 

The UL-listed seal goes on stand-alone products. It is usually used to ensure the safety of products that are consumer-ready and go on the market.

TO become UL listed, more product testing is involved when compared to the more simple UL certification. 

When a product is UL listed, not only it is safe for consumers, but it also meets sustainability standards.


The Difference Between UL Certification And Listing

For some UL marks, the term “certification” is used to communicate that the organization has run tests on a prototype that has been provided by the manufacturer and it meets certain standards of safety.

The term certification, however, does not imply that the product is approved for use in all potential applications.

UL listing refers to stand-alone products that have very specific functions and have been tested and recognized safe for a specific category of equipment and application.


Is UL Certification Mandatory To Sell Products?

The UL certification may not be mandatory, but most US retailers, for example, won’t sell products that don’t come with such certification.

If you are buying your air purifier from outside the US, you have two options:

  • You still ask the seller if the product is UL certified
  • You get informed about what is the correspondent agency outside the US and check that the air purifier you are purchasing is certified by them.
