Has anyone tried making a PAPR or HEPA stroller? A few people have mentioned the concept but the only source I've found is this one paper: https://www.researchsquare.com/article/rs-2430680/v1

I'd love practical tips. Right now I can't go into stores with my baby because she can't mask, having the ability to wheel her inside would greatly expand what I can do while caring for my child. Also useful during wildfire smoke.

"CHEPA is a free, easy-to-use calculator that helps schools and local authorities explore whether adding a HEPA filter unit could improve classroom air quality and what it might mean for energy use. It is independent, evidence-based, and co-designed with schools." https://www.sei.org/tools/chepa/ #AirQuality #Schools #HEPA

Outdoor air quality here is still terrible, so I trimmed some berry-laden branches from my sea buckthorn bushes (masked of course) and brought the branches inside to actually pick the berries. Bonus: I could sit down while harvesting indoors, surrounded by air purifiers! Then of course I had to sabotage all of that effort to take care of my health and bake a cake with my berries. #gardening #baking #airquality #HEPA @altbot

I facilitated an online workshop for @freetechproject tonight and it's the first time we tackled technology to fight #Covid (Co2 monitors, air purifiers, #HEPA, #CorsiRosenthal boxes, #NukitTempest, etc) as well as why this is important (what Covid is, how it spreads, etc) and the small (predominantly older) group was very open to the ideas, sincerely inquisitive about the topic, interested in reducing risk, aware of inclusion issues, and sensitive to my own experiences as carer for a partner disabled by Covid. I'm also realising that people genuinely refer to "Covid" in the past tense sometimes because they wrongly associate it with government policy, while at the same time they very clearly understand that #CovidIsNotOver. My point is, keep tackling the topic, and keep giving folks the benefit of the doubt -- humans are of course good at heart and state policies, and obviously the establishment media, may very well indeed not, in fact, reflect people's actual concerns about Covid.

Reducing Your Microplastic Exposure: D rinking filtered tap water rather than bottled water can reduce your microplastic intake by as much as 90%. #microplastics #bottles #containers #hepa

No sé si sabíais que he experimentado un retroceso importante de la alergia. No sabía qué era.

Ahora ya lo sé (movidas ambientales) y voy a tener que comprar un aparato con #filtro #HEPA en casa, al margen del deshumificador.

¿Me recomendáis aparatos no muy grandes, majos y no muy caros? Gracias.

Indoor air quality and ventilation folks… I need some help!

I’ve been dealing with terrible VOCs in my apartment that are making me sick. I’ve been trouble shooting for months but can’t figure out where they’re coming from.

My building has four MAUs (make up air units) on the roof that are supposed to pressurize the hallways and supply fresh air from the roof. They needed replacing, and when they were turned off the vocs in my unit dropped considerably.

Best as I can tell the pressurization must be causing excessive air leakage from someone else’s unit into mine.

I have to constantly keep a window open in order to run any exhaust fans, and they’re still high.

Here’s my latest dilemma. I’m in a tiny condo with just a living room and bedroom. Living room has a sliding door to a balcony and bedroom has a window.

I want to put a portable air conditioner in the bedroom as it runs ridiculously hot, but that will mean sealing off the window.

The portable unit comes with a hose to vent the unit out the window … so does that mean it will constantly ventilate as long as the unit is “on”?

If that’s the case it might actually help the VOCs, but I’m unsure if I’m understanding correctly.

I assume if the unit is “off” it would provide less fresh air than an open window, but appreciate any advice!

“Relying on #vaccinations as the measure of whether people are likely or not to transmit (#COVID) to vulnerable patients is a very dangerous strategy,” Gregory said.

Instead, he added, it would be best if everyone wore masks in public health settings whenever possible.

Mitigation measures such as properly worn #N95s, #HEPA air filtration, ventilation and avoiding high-risk areas like indoor crowded spaces are “all variant proof,” Gregory said. “No variant has evolved to circumvent an N95.”

In educational institutions:
* #HEPA cleaners and #UVC lights are effective, especially when properly sized and positioned relative to the infected and susceptible persons.
* HEPA cleaners could reduce #aerosol particle load by 85-95% within less than 20 minutes of operation.
* Implementing proper #ventilation and air cleaning strategies can create safer environments for students and staff, reducing absenteeism and promoting better learning conditions.

Today Swedish #masks brand #Airinum is launching #Hale, a portable #airpurifier. https://www.kickstarter.com/projects/airinum/hale?ref=discovery. It claims to remove 99% of airbone particles incl. virus. There are no certifications like #K95 or #FFP2 for purifiers, other than #HEPA, which doesn't give the same level of assurance. This piece of research from Aug22 is promising though https://pubmed.ncbi.nlm.nih.gov/35947419/, but Airinum stopped short of guaranteeing safety from #COVID for @longcovid sufferers. Thoughts? It would be a gamechanger for me

Well-invested startup funds – #HEPA air purifiers for all lecture halls and seminar rooms of our institute.

Why isn't our government mandating (& providing funding for) improved ventilation in public buildings? Study showed with 2.4 changes of the air per hour, cases dropped by 40%. With 4 changes of air every hour, infections dropped by 66.7%; when replacing the air 6 times each hour, infections go down by 82.5%! We need this in theatres, restaurants, schools...

"Fachleute warnen vor schlechter Raumluft: Mehr Infektionen"
https://www.sn.at/panorama/oesterreich/fachleute-raumluft-mehr-infektionen-150178543

"Schlechte Luftqualität in Schulen, Kindergärten und Arbeitsstätten senkt die Leistungsfähigkeit und hebt das Covid-19-Infektionsrisiko, erklärten Experten Freitag bei einer Pressekonferenz in Wien. Sie nannten es unverständlich und unverantwortlich, dass man in Österreich Lufthygienemaßnahmen wie Filter- und Lüftungsanlagen vernachlässige und bei der aktuellen, seit Pandemiebeginn höchsten Covid-19-Welle in Krankenhäusern und Arztpraxen nicht verpflichtend Masken trägt."

"Es ist medizinisch und ethisch nicht ok, dass sich Menschen in Krankenhäusern mit Infektionskrankheiten wie Covid-19 anstecken, wenn dies leicht vermeidbar ist"

@drclareharris 100% Clare! I absolutely agree.

As someone who is living with #LongCovid I’m uniquely qualified to tell people they do not want it. #CovidIsNotLikeTheFlu

#FilterYourAir 🌬️

Adequate #ventilation and #filtration are so important and not only for Covid.

Build a #CorsiRosenthalBox or

Buy a #hepa or BOTH!

Stay safe out there!

@MadisonMonkey Perhaps, after a repeat bad “Tripledemic” bout this fall/winter, which will have negative effects on both healthcare AND the economy, there will be more incentive for governments and businesses to pay attention to clean air.

They can’t live in denial forever. It’s just unfortunate that scientists and advocates have predicted and warned all along but governments wait to “learn the hard way” first. 🙄

#COVIDisAirborne #CovidIsNotOver #cleanair
#HEPA #CO2Monitors

Every anti-vaxxer should be a clean air advocate. Saw the argument that "the Black Plague disappeared without a vaccine". This is misleading as it is still in existence, it just doesn't spread like it did because we figured out how it spreads, and then made the proper changes.

We know how #COVID spreads, #COVIDisAirborne, so if we clean the air via #HEPA and #UVC, and #WearAMask, we stop spreading it –and that means those who don't want to get vaccinated will be more protected.

Hey #CovidIsNotOver people! I start a new job tomorrow (fully in person) & am a little nervous about keeping myself safe. Here’s what I’ve got in my toolkit:

1. #3MAura and #VFlex #N95 #Respirators
2. #Hepa purifier for my desk
3. #Co2 monitor
4. #Enovid #NONS nasal spray
5. #CPC mouthwash
6. #SipMask

I’ll only eat outdoors, weather permitting; otherwise I’ll find a private room & run the purifier before unmasking. I will use #NasalSpray several times per day.

Anything I’m forgetting? 😷

My indoor #PM25 reading is FINALLY as low as is measurable by the #AirPurifier!

At some points yesterday, it was up to 35 ppm even with all windows closed, air conditioners off/sealed, exhaust fans off, etc.

UPDATE: My brother stayed #COVID FREE according to all test results over the past 7 days!

How can we trust the test results given the evasiveness of #kraken?

Maybe we can’t completely, but the fact that he took #RAT on days 0 to 6, waited until 6+ days had gone by, THEN got his #PCR and #NAAT samples taken (all negative) seems good.

PLUS no development of symptoms. Slept in a #N95. #HEPA and #ventilation also helped keep him healthy!

#CovidIsnotOver #CovidIsAirborne @novid

@major

Well, we now know how to stop #airborne #pandemics.

(#CovidIsAirborne; #FluIsAirborne)

We stop it with #HEPA filters, #CorsiRosenthalBoxes. And with #N95 / #N99 / #P100 #elastomeric #respirator #masks.

But right now DOCTORS are blithely mass-infecting patients -- and of course nowhere else is doing anything either -- so our society is basically doing nothing and helping the virus spread.

We should try doing something.

I prepared a handout for doctors. https://nerode.org/clean-air

Q. What was the origin of the #pandemic?

A. The origin of the pandemic was:
- governments and medical professionals lying to the public about how Covid spread (#CovidIsAirborne by #aerosols) and refusing to tell anyone how to protect themselves (#N95 #N99 #FFP3 #P100 #P3 #elastomeric #respirator #masks, #HEPA filters, #CleanTheAir)
- and talking nonsense about handwashing instead

The origin of the virus is irrelevant.

HEPA filters and P100 respirator masks would have prevented the PANDEMIC.

@luckytran

I get really terrible PSAs from government agencies on my Facebook feed.

I comment on all of them telling them they need to talk about how #CovidIsAirborne, #InfluenzaIsAirborne, #RSVIsAirborne, it's stopped by #N95, #N99, #P100 masks, #HEPA filters, #CorsiRosenthalBoxes, and I drop a link to https://its-airborne.org .

Maybe I'll reach someone. I'm now doing more public health work than the CDC, WHO, or the state health department, which is ridiculous.

#N95 outdoors
#P100 elastomeric indoors
