Can u explain what they are doing wrong? I’m fixin to buy some and I don’t want to miss apply them. I’m surprised by this because I figured anyone diligent enough to seek out n95s would know how to use them.

I think they’re uncomfortable if you wear them properly for extended periods. But you can certainly figure out how to fit them, even though half the people I see using them are doing it wrong. Mostly they have obvious gaps between the mask and their face. Perhaps due to using the wrong size, I’m not really sure.

Ty it’s amazing how many people can’t figure this out w any type of mask. The lack of common sense in usa#66 is frightening.
I got some of the Powecom from here: https://bonafidemasks.com/
Under $2/mask if you buy 50 or more. Shipment arrived very quickly.

How many times would you comfortably reuse one of those KN95 masks before disposing? I’ve been using either surgical masks or a cloth mask, but am considering getting some KN95s.
I found a better source than ebay for Raxwell masks: Raxwell RX9501 Disposable KN95 Respirator | Saf-T-Gard International
Under $2/mask even after the ridiculous $17 shipping.
I think the Raxwell fits slightly better than the Powecom. If I exhale heavily through the Powecom, the air breaks the seal on the back of my cheek, sending some unfiltered air behind me.

Their branding doesn’t exactly scream competence…
(just kidding, of course. thanks for the link).
Got the Powecom masks in the mail today, pretty good, better than I thought with the fit around the nose, but like @eeAWW said, breathe heavily and the seal around the cheek breaks. Going to continue doubling with surgicals until I hear otherwise.
Hah at first I didn’t trust them because with that name, it sounded like a website that popped up overnight to profit from the pandemic. But apparently they’ve been around for a long time and they have a big warehouse/plant in Illinois.
My raxwell masks from saf-t-gard came on Monday. Unlike the ebay raxwells, the ink markings on these actually match the ones on the raxwell site (I didn’t look closely enough before). The ear bands are also noticeably tighter, so the ebay ones might be counterfeit (which wouldn’t necessarily be the seller’s fault). I said the ebay ones had a great fit; the saftgard’s fit is even better (at the expense of some ear comfort) because the mask is pulled more tightly to one’s face. This is my go-to mask from now on.

This link is from a nypost article, 10 N95s for 89.99, thoughts? I’m hovering over the buy button atm.
Pulled the trigger, feels scammy but I’ll report back when/if they arrive. I don’t mind the price if they are legit, I had a few N95s at the start and prefer them to the KN95s that I’ve gotten so far, mainly in the tightness of the seal above the nose.
I bought masks and filters here. They’re incredibly comfortable.
A neighbor said she bought some of these, which claim to kill the virus by zapping it with cations until the enclosure decays, bursts, and the now-harmless virus guts spill out. Available in the U.S. under EUA, and submitted for FDA approval. I couldn’t find any real info about the science beyond the Mrs. Frizzle description.
$25-$30 each
What’s the actual science behind the technology?
The principle underlying our technologies is the ability of polycationic surfaces to inactivate microorganisms including bacteria, viruses, and several types of fungi, and to do so without leaching.
This principle has been described in scientific literature for two decades, but its understanding and practical applications have been limited. Livinguard has leveraged this principle to invent and patent a paradigm shift from conventional approaches:
- Range of methods to bind a range of cationic compounds to textiles and other surfaces
- Portfolio of optimized chemistries to inactivate bacteria and viruses, without using traditional metal based antimicrobial agents like silver, copper, zinc, etc.
- Methods to combine these with other properties, such as water repellency, hydrophilicity, etc.
According to the the scientific literature, it is probable that the inactivation mechanism of viruses is based on the distortion of the protein capsid by adsorption of negatively charged proteins to the positively charged surface, finally leading to the release of non-infectious RNA.
Tests have shown that after multiple rinses or washes, the treated material (specifically textiles as tested so far) maintains its properties without leaching. This lack of leaching is the underlying reason why the antimicrobial performance is so durable as well as why it is safe for skin contact.
Yeah, that’s what I found. “Patent a paradigm shift”, “optimized chemistries”, “probable”. I guess probable is OK, but the other stuff sounds like snake oil. If it’s patented, why not explain exactly what the compounds are, how they bind, why they don’t cause cancer, etc.

I bet it works great if everyone else is wearing a mask and staying 6 feet apart.
