[Costco] KN95 Disposable 5-layer Face Mask, 20-pack - $64.99

Costco now has these hard to find KN95 masks. Let's not forget the fact that these are available now and its $3 shipped. I received these in the mail 3 days after the order despite the delay message title.

It is $59.99 at Costco store. (Thanks Teneur!)

A bit more expensive that price found at foodyworld/T&T and other Asian supermarkets but the question is how is the quality.

It was as low as $20 for 10 as far as I’m aware at those stores and the price has being trending downwards.

Has anyone actually tried these? I wonder if these are more effective then the other kn95s you see floating around on living.ca or amazon etc...

How to try and test effectiveness? Talk to a covid patient? :))

Joke aside, do we really need n95 if we just go grocery kind activities? If you have high risk people at home or visit long term care or hospital, it's different story

Are these even worth 65+3 bucks? Guarantee to protect me from COVID-19?

Definitely not guarantee, even if you're using N95, it is not guarantee.

Personally don't think it's worth, but that's because I stay 6ft away from others so what disposable mask i use is sufficient. But if you interact with more people more often, could be.

These are researchers from the Department of Materials Science and Engineering, Stanford University, Stanford, and Stanford Institute for Materials and Energy Sciences, SLAC National Accelerator Laboratory, Menlo Park, California, United States.

Heating at 85*C, 30% humidity for 20 mins allows them to be re-used many multiple times. Donning/doffing the masks can also reduce efficiency over time. Presumably N95 masks have a better fit than surgical masks, too, so fiddling around with the mask will also disrupt the barrier over time. But apparently, lowering the humidity (eg. in an oven) also does not affect the efficiency, which they tested at 20 cycles.

https://pubs.acs.org/doi/10.1021/acsnano.0c03597

This research was funded by the NIH.

This study found significant degradation after just two cycles of heat treatment, however.

Overall, it seems that N95 is better if you intend to re-use them by sanitizing with dry heat. I'd say this is potentially worth it if you re-use each mask at least 6 times. The studies likely have methodological differences but perhaps if you average it out and throw each one out after at most 10 dry heat cycles, you'd be way more efficient than buying any of the disposable masks I've seen sold at Costco or elsewhere.

If anyone is interested home hardware also has 20 packs of kn95 for 49.99. Item 1637046. Never thought we'd have something cheaper than Costco.

As I recall, the batches of defective masks that the Canadian government got scammed into purchasing were KN95 masks that look remarkably like the ones from Costco. Could these masks be rejects from the same manufacturer that are now being resold as "non-medical" masks?

Thanks O.P.
Saw that fda approved hospitals for use of kn95 but given the review by niosh, seems questionable if people that already use any other type of face masks need these... No specifications from Costco on who manufactured or if Niosh approved the 95 claim. Usually a fan of costcos purchasing team for the quality items, but wonder if they just couldn't say no to picking these up deeply discounted and turning a huge profit.

Honestly i think they obstruct your breathing way too much, but that's me. I get it, surgeons and doctors use them, but they're not running around a grocery store while using them.
