How do I properly thread the strap through the buckle?

If the strap needs to be threaded through the buckle again, refer to the diagram below to make sure it is threaded properly. The portion of the strap WITHOUT Velcro should be threaded through the buckle. If the strap is not threaded properly, the Car air purifier may not be fully secured and could detach unexpectedly.

After routing the strap through the buckle, please use it to install your Car air purifier according to the installation instructions in your Car air purifier User Manual.
