Beware that Readimask is being recalled: https://healthycanadians.gc.ca/recall-a ... 7a-eng.phpcahk wrote: ↑ No one can tell you which one to buy, simply because there's such a flood of them coming from overseas. There's no way to guarantee the package of KN95 you pick up is actually legitimate and not a knock-off, which is why NIOSH has been very specific to indicate on their reports barring a certificate of authenticity from the manufacturer, they are not using the test result as a "yay or nay" certification.
You can easily find a list of FDA authorized, non-NIOSH approved respirators under Appendix A: https://www.fda.gov/medical-devices/cor ... pment-euas [And conversely under Appendix B for those no longer authorized]
BYD has plenty of N95s you can buy to your heart's content: https://bydcare.ca/store/ols/products
If money is truly no object, you can find US-made, NIOSH approved N95 respirators (with or without eye shield) at https://readimask.com/readimask-store/
Somewhat ironic that you are posting links to NIOSH reports of poor quality masks and at the same time recommending a product that is being recalled.
