How much of the info is hallucinated? All LLMs have hallucination problems. They are biased to givew confident, plausible answers regadless of whether they are true or not. So you need to already be a subject matter expert to be able to spot the hallucinations, which I am not.

I definitely do not need the siren for amber alerts.

I want to participate, but the loud siren that goes off no matter where I am or what time it is makes me more likely to turn off amber alerts than if I just got a regular notification. It's counter productive.

Thanks to @nukit.bsky.social for the use of the test sample and spectrometer.

I added the hours meter to the power supply cable, so no modification to the Lantern was made. The hours meter will count up as long as the Lantern is supplied with power. That means I need to make sure to leave the Lantern power button engaged to get accurate readings.

Nukit loaned me a UV spectrometer that includes the Far UV 222nm output by the Lantern. The spectrometer enables objective measurement of the exact output.

I've just added an hours meter to the @nukit.bsky.social Lantern I was sent. Now I can test the lamp life in a more robust manner.

Some of their older posts on Reddit at Masks4All are under an account that got deleted (Vasilisnp) for some reason, but you can still read them, and also recognize them by the detailed information and great organization.

Vasilisnp2 consistently posts some of the most insightful and well presented content about respirators from around the world. I have no idea where they get all the information they do as the industry is rather opaque to outsiders, but I highly recommend their posts.

Love 'em or hate 'em, there is a great new write up on the hows and whys of bi-fold respirators, the shape most people associate with KN95s by Vasilisnp2.

Both the Lantern and the borrowed UV Spectrometer were sent to me without obligation. I don't have any agreement to write anything specific, or anything at all, about the Lantern, but I try to be sure to disclose when I've been sent items for review.

This is my initial unboxing. I'll be working on a review, but that could take a while because this is my first time trying out Far UV.

You can read more about the Lantern at the Nukit site (regular web link - I do not get a commission).

Instead, Far UV needs to be thought of as a whole room treatment and you need enough Far UV lights to do that. How many lights you'll need depends on the room size and the power and the beam spread of the lights.

I think the most important thing to consider about Far UV is that it requires a dwell time to work, so it can't create a localized zone of instant clean air like some sort of SciFi beam weapon.

I've mentioned this issue in the past and @nukit.bsky.social was kind enough to loan me a UV Spectrometer that includes the 222nm Far UV spectrum.

For respirators, I have test equipment to measure how well they fit and filter, but for Far UV I just have to hope that the manufacturer's claims are accurate, leaving me with no way to differentiate between different vendor's products other than cost and manufacturer's claims.

So far, I've not posted about Far UV because I didn't have a way to talk about it objectively with UV measurements of my own.

Without being able to measure the invisible UV output myself, what can I say about a UV lamp? "It looks nice"? "Easy to mount and turn on"? And with UV, details matter.

Other companies make similar testing machines, including Accutec, OHD, Sibata and OpenAeros.

I have no financial interest in promoting PortaCounts. I use them, but have no affiliation with the manufacturer, TSI. They are just an all around better fit testing method. They are more accurate and not reliant on subjective impressions of taste.

PortaCount Fast Fit testing takes just 2 and 1/2 minutes (not including the time it takes to put on your mask and purge ambient air from it) and gives an exact numeric score. The score tells you if your mask currently protects you well or if you need to try a different model for better fit.

Sax either doesn't know what is in fit test solution, or doesn't care because he's fixated on casting it in the worst light he can invent without regard to the facts of fit testing.

If Dr. Sax is so against qualitative fit testing, he should advocate for PortaCount fit testing at his institution.

Qualitative fit testing uses a nebulized spray of either pure saccharine dissolved in distilled water or pure Bitrex dissolved in 5% saline solution. There is no fragrance. It is a taste test, not a smell test.

Dr. Sax either doesn't know that OSHA-approved quantitative PortaCount fit testing exists, or choses to pretend it doesn't so he can generically mischaracterize mask fit testing to try to falsely discredit it.
