The IPMA has released a very interesting statement detailing the potentially major threat Storm Charles posed and why it ultimately failed to reach that potential.
The article: ipma.pt/pt/media/noticias/ne…
I’ve already mentioned a lot of these points in my last few updates, but it’s interesting to see it written from the perspective of the IPMA and how it affected their issuance of Red Warnings for both rain and wind.
I commend the @ipma_pt for the way they handled this storm, even though the impacts were nowhere near as significant as they could have been. This is how lives can be saved when the next major storm like Kristin actually affects Portugal.
This was very difficult to read. But a useful reminder that everything is not as well as the Twenty-Nineteeners insist.
Resist.
The Covid Chronicles.
An older cousin blocked me on FB back in 2023 after I posted about Covid-related illnesses and the steep increase in Cancer. She called my mother to tell her that I was “Fear Mongering” and “everyone just wants to enjoy their life.”
Fast Forward-Her husband was diagnosed with Multiple Myeloma in 2024.
She tells my mother that there isn’t a family history of Cancer in his immediate family and everyone is puzzled.
After completing Chemo in January 2025, they celebrate by going on a 10 day cruise.
They, along with two sisters all come back sick. They test positive for Covid on the cruise.
Her husband ends up in the hospital upon returning to Florida.
February 2026, Cancer has returned.
Chemo is completed in June or July.
My cousin plans a cruise and a send off party for 4th of July to celebrate.
In September, she tells my Mom that one of our cousins has died of “Natural Causes.
She was 63.
She then mentions that each time she goes on vacation, everyone ends up sick, and they suspect that her husband’s Cancer has returned.
He died on Tuesday.
My mother’s conclusion is “This is why we need to go to some of these celebrations Chuan!”
The Covid Twilight Zone continues….

I sincerely apologize; since leaving Zimi, I have had no control over how they choose to handle issues. Following our departure, our team immediately established Ziga, with the goal of producing superior masks as quickly as possible—incorporating all the experience and technical expertise we have accumulated over the past few years. Our greatest wish is for everyone to be able to use the new Ziga masks.

Zimi mask quality control issues with some recent production:
"Following some feedback I received last month, I reached out to Zimi to have their masks tested at a laboratory, which helped them identify the underlying issues. I suggested that Zimi publicly disclose the situation and the steps they are taking to address it, though they ultimately chose not to follow this advice. That said, it is certain that the vast majority of their mask models and production batches are completely free of any issues. Zimi has information regarding the specific batches affected; you can contact them via email (at zimiair.com) to verify which batch your masks belong to."

Note that Zhou Liang left Zimi earlier this year and is no longer officially associated with them. He has since formed Ziga which is currently creating improved frame masks.
The quality control issue seems to be limited to a batch of masks made over the summer from filter media that had not been properly transported or stored. The filter media isn't filtering to its rated specifications. It is still filtering, but not quite as well as it should be.

Vsak dan so milijoni bolnikov izpostavljeni prepričljivim okužbam s strani zdravstvenih delavcev. Tisti, ki zaradi posledic umrejo, so vsi po vrsti žrtve uboja iz malomarnosti, pri čemer zdravstveni delavci ne morejo uporabljati neznanja kot izgovor za ogrožanje bolnikov.

Jin Asia obtained the European certification with their Bibari ffp2 and ffp3 masks. Hopefully, we'll see NIOSH N95 and N99 cup and inner frame respirators the next couple of years in the US from Korean companies.

Leaves are falling and airborne pathogens are circulating.
Wear a well-fitted respie if you want to work and walk as much as you did before.

After continuous, successive rounds of iteration—each building on the previous one—it now looks like this and has earned AHAM certification.
The main improvements over the original version are:
1. Four 14 cm computer fans replace the exhaust fan, providing greater airflow and quieter operation. Low-voltage DC power replaces high-voltage AC, making it safer.
2. Four more pleated E11 filters (equivalent to MERV 16) replace the less pleated MERV 13 filters. And also provide the option that activated carbon filled in the filters to absorb VOCs.
3. A plastic casing with built-in magnets has been added around the filters, so tape is no longer needed, and the filters can be removed at any time.
4. A display screen and a PM2.5 sensor have been added, so you can check the air quality at any time.

In response to the Covid-19 pandemic, @JimRosenthal4 and @CorsIAQ designed the Corsi-Rosenthal Box — a low-cost air purifier with major performance. The duo shared it as an open-source, DIY project which snowballed into a global, grassroots movement of air purifier construction.

Behind them is a collage of headlines discussing CR boxes on a yellow background. Text reads: The box that swept the globe. In response to the COVID-19 pandemic, two friends, Dr. Richard Corsi and Jim Rosenthal, designed a powerful air cleaner that rivaled commercial air purifiers in both cost and performance. The duo released their findings as an open-source, DIY project for anyone to build, which quickly caught on across the world. Their work brought clean air to classrooms, workplaces, homes and even the White House. In October 2022, the Corsi-Rosenthal Foundation was created, with a mission to improve human health by promoting clean indoor air and supplying air purifiers to those in need.

After one week, please visit Ziga’s purchase website, zigaair.com. We will begin rolling out sales of our third-generation frame-style masks.

Nobody in my life listened to me about protecting themselves even though they knew I’d been sick and struggling for more than 25 years w/o even a proper diagnosis. They figured they were “healthy” not a disabled loser like me and now some have chronic issues and some have died.
This is why I gave up on actual medical *help* arriving for me anytime soon.

We conducted internal testing among Zimi consumers in China, and they rated Ziga significantly higher than Zimi—technology is advancing. This is also the culmination of my work over the past decade.

J’ai déposé une proposition de loi pour en finir avec l’invisibilisation et l’abandon des malades du Covid long !
Les chiffres sont inquiétants : en 2022, Santé publique France recensait 2 millions de malades, dont 700 000 atteints de formes sévères. Une personne atteinte sur cinq cesse de travailler, et un grand nombre de celles qui poursuivent leur activité ne peuvent reprendre qu’à temps partiel ou finissent par être licenciées. Des jeunes sont radiés de leurs établissements d’enseignement, et les enfants malades restent sans repérage à l’école, faute de formation des médecins scolaires.
Voilà ce que contient ma proposition de loi 👉
Zimi users, anyone?
I don't think you tried the water thing with a Zimi, right @AdvancedTweaker ?
