I look away for two seconds and jokes are already happening? Classic Lloyd.

I just realized you are doing these daily videos now! So many masks to review! Thanks for this (and I thought your joke was funny).

[DivaWright]

Personally, I have these masks and they work just fine. I am taking care of my twins who caught Covid from school and I've tested negative each time I've been tested while using these masks. Wear them properly. If you don't feel safe wear a double mask.

Last year I wanted to buy those mask but I decided that they were not good and this video prove it thank you

Hello, hope everyone had a nice weekend! 😊💜

[julieloofbourow]

You did another review the other day on the Yuikio KN95 mask and that mask got 99%. This mask got a 63% but both these mask are made by the same company and look very similar. Can you comment on the difference in materials if there is any?

[PrimitiveGardens]

Important info here- thanks for posting it.

[abcegc]

They spent more money making the packaging pretty.

[dolphinsnshells]

lol a Barbie box innards …. You had to think about that one😷🤣

Do you have a list we can visit of real kn95 masks?

[coffee_]

I have noticed that the kn95s from well before do not have the standard printed on the side of the mask. Does this mean they do not meet the standard?

[jamesharold]

All of these kn95 masks sold today look to be identical in thickness and overall construction, the only differences I've noticed is one will say kf94 only and others will have both the GB2626-2019 standard and kf94. Seems like anything made in China is just not trustworthy.

You NEED to create your own facemask brand !!

[jasonsteinbaum]

Thanks for doing these reviews. helpful. Quick question: I purchased these YOTU masks before seeing your video. Based on your test, are they better than regular surgical masks or should I just switch back? On the screen of your device, I think I saw that they are about 65% effective which to my totally uneducated eye seemed better than a surgical mask. Did I read that right?

[MalcolmTheProfessor]

The 63.7% filtration was tested on what particle size, “respirable”, that is, less than 3 to 5 microns?? Or better yet, 0.075 microns, the N95 standard particle size?

[azncoolboii]

Should be more intervention by Amazon barring these products that just aren’t legitimate

How disappointing! Always hoping the underdogs do well. Thanks Lloyd.

[MadDog]

Thanks to the bad jokes we have you building quality masks. Otherwise if you had good jokes you’d be a comedian instead.
