i have been searching for days what is the difference between the 1873v and the Aura 9332+, i can't tell the difference. Is there any?

From the paper: The 1873V+ and the 9332+ masks are the same mask design and shape, branded for different industries. When one has been face fitted to, the face fit test is valid for the other. These masks are different from the 3M 1873V mask and as such require a separate fit test. The two masks are not interchangeable.
