How to Tell if Unit is UL Certified
Date:May 07, 2019
Here is how to tell if someone is genuinely UL listed:
1) Go to UL.com and click on the link Certifications ul-product-identity
2) Enter in the UL file number in the bottom box and click search
3) Verify that the company information that comes up matches (the address must match per UL requirements to inspect the facility)
If this information matches, then you can feel comfortable knowing that these units meet the safety standards set by Underwriters Laboratories.
