Good list of options. How many do you use on a daily basis? But I don't see masks coming back in any big way unless people really start noticing sickness all around them (even if mandated by government). I personally have filters in the house, vaccine (flu only this year), stay home when sick, and always use mouthwash. I have seemed to avoid any major sickness (maybe a fever for a night or two this winter)...let's hope I keep it that way.

I mostly wrote about the things I use myself.

Everyday?

Thank you!

I now have a name for the “Corsi-Renthal” box fan filters that are excellent for picking up the microfibers from polishing with synthetic cloth or from cutting and trimming of fabrics. If a process generates dust you can see and clean from surfaces later, you are breathing it.

Beautiful mockup of the cheap air filter box… as a fly deck technician I was shocked to find that many facilities will put workers in closed spaces with dry ice or tank carbon dioxide. Fast food places have better signage than some manufacturing facilities or college labs when it comes to the carbon dioxide tanks. The lessons never get old when the audience is forever young. Teaching is about high employee(student) turnover.

I was also surprised by the lack of CO2 monitoring in the homes of people being treated for poor sleep or repetitive morning headaches. A cpap does not improve the quality of the air.

OSHA for indoor offices? About 1500ppm. Standards for commercial airline cabins were improved thanks to work by the airline stewardess unions. It costs money to heat or cool outside air for passenger survival. More fresh air means less pathogen exposure too.

Free coffee not keeping the office hopping? Try fresh air. Get a cheap carbon dioxide monitor and check your office and the room where you sleep. The more people and pets in a space, the more outside air should be conditioned by your HVAC. Older systems may not have any outside air intakes. Your fresh air is then coming from leaks or opening and closing of doors.

Thanks. We are getting less and less in the USA.

Solid recommendations but unfortunately there’s very little solid evidence on nasal sprays.

They definitely cannot be relied on as a transmission prevention strategy, even as part of a Swiss cheese model.

A lot of the sprays are missing human clinical trials, have finished the trials but refused to publish results (suggesting perhaps disappointing results), have demonstrated no greater benefit than placebo, have conflicts of interest in their studies, are missing key information or clarifications in their studies, have procedural errors and omissions, and/or are making claims that are simply not backed up by evidence.

Some of the sprays have ingredients that can harm us and actually potentially destroy our cilia and mucosal lining. The FDA has also not approved any spray for prevention of covid.

They can also impact pcr and rapid test results which is concerning.

A friend of mine who is a biochemist has done incredible deep dives on nasal sprays and the mechanics behind them as well. I highly recommend these two posts from them if you have instagram: https://www.instagram.com/p/DBXTIeryTth/

and https://www.instagram.com/p/DEsx-u6zD8x/

Additionally, Dr. Hoerger (who is well respected in the CC community) also agrees that there is insufficient evidence on any of them (scroll down in this thread to see his comment on nasal sprays specifically: https://x.com/michael_hoerger/status/1834810693205274886)

I’m honestly quite sad because I bought so many and wanted to trust that they were another protective layer, but the science is just not there.

Hoerger is not a source I would consult.

Is anyone doing this on a daily basis? Nasal sprays? If it works, I might start it. Anyone have an experience with this?
