50-Ct BYD CARE KN95 Respirator

How can I know if the BYD masks will protect against the COVID bacteriums?

FDA didn't approve BYD is more because of political reason rather than its quality reason. //@Anonymous: FDA did not approve any kn95 mask, only authorized some kn95s for emergency use (EAU). In June 2021, FDA revoked EAU for all kn95 masks. So currently none of kn95 mask has FDA authorization at all. //@anonymous: If it's FDA approved, it should be roughly the same. Just a matter of quality control and comfortability. You will never get every single one of them lab tested anyway //@Anonymous: So you measured filtration efficiency of different masks? //@neuron66: Tried multiple brands of masks including current brand HoMedics from Costco. BYD is the best quality among these masks.

BYD KN95 is 3-layer vs most KN95 masks are 4-layer

So you measured filtration efficiency of different masks? //@neuron66: Tried multiple brands of masks including current brand HoMedics from Costco. BYD is the best quality among these masks.

Tried multiple brands of masks including current brand HoMedics from Costco. BYD is the best quality among these masks.

No 20% off shown for KN95 mask.

How to get 20% off? Don't see coupon there.

KN95 one doesn't have 20% Off coupon

I don’t see extra 20% off for the KN95. How to get it?

Look at the two end sides of the box: one has QR code, the other has expiration date and “ASTM F2100 Level III”. //@anonymous: There is no indication on the box that says ASTM Level 3. Level 3 is almost like N95, there are a lot of mis-represented information out there. I have tried to buy Level 3 masks and have found ones on eBay and/or Amazon to be almost 100% fake. Keep in mind, even level 1 masks are 3-ply. Level 3 is a whole different animal, do not be tricked!

ASTM Level-1 is >=95% filtration vs level-3 is >=98% filtration plus anti-splashing, when these masks achieve 100% sealing. This kind of mask can never be sealed 100%, not even 70-80%. So 3% difference on filtration doesn't matter much.

yes, at least from my local COSTCO, it says clearly LEVEL 3. Guess YMMV or it's very regional.

The green box is Level 3 surgical mask. Read the description on the box carefully.
The blue box is level 2.
The one sold in Costco is not surgical level that's why they are cheap.
BYD mask quality is so far the best I used. Have used more than 10, 20 boxes surgical BYD masks since pandemic started in 2019.

These are indeed ASTM Level 3 masks. It's said on the box that I purchased from Amazon.

Costco's are not Level 3. Costco only carries BYD masks for general uses which are much cheaper than Level 3 masks. //@Anonymous: Local Costco has BYD level 3 masks for $6.99 for a while.

3-Ply IS NOT Level 3. There is a huge difference!

but you can buy multiple times //@Anonymous: 15% for one item only:-(

I don't think the Costco one is the Surgical Mask, but it is general use only. //@anonymous: oh, man, Costco only 6.99 for adult. and kid buy 5 at $25.00 (out of stock)

This is ASTM Level 3 masks. Costco's is not. //@Anonymous: oh, man, Costco only 6.99 for adult. and kid buy 5 at $25.00 (out of stock)

15% for one item only:-(
