vQuality is an interactive platform that provides you with the as-made testing performance of the products you purchase.
Now that’s a stamp of trust.
Let’s show you how.
Oops. That didn’t work. Let’s give that another try below.
I have located the Lot Number on my package:
Can’t find the lot number? You can locate it on the packaging or on the mask itself.
The Process.

We don’t just make a face mask and toss it in a box. There’s a LOT more to it.


Samples from each lot are removed to be conditioned in a chamber for 24 hours. Kind of like taking a day–long nap.


Next, the sample masks get ready for the filter test, which checks to see if any nasty little particles can get through.


Now we stretch. The straps are pulled tighter than those pants you own that haven’t fit in 5 years.


Ever snap one of the straps? We test ripping force – that way we know your straps won’t rip off like those fake masks you’ve worn.

No performance anxiety here. Just quality you can trust.
Let’s locate that lot number and get to work.
Now that you know what to do, let’s stick you in front of some helpful performance stats.
