H5N1 looks like it could be dangerous?

Thank you so much for this. It makes me feel less alone. ❤❤❤

I don't want to diminish how excellent PAPRs can be, nor discourage folks from using them if they want to. It's awesome for folks to have this tool available as one of many and folks should absolutely consider using it. But, I am concerned that there are some potentially misleading discussions in the initial presentation: - APF is not the right metric for understanding the level of protection a mask provides you as an individual. APF is an anticipated minimal level across a group of people, not the level of protection you will receive. Your protection is function of filtration and fit, not filtration and APF. - There is a lot of work being done by "may" in the discussion of respirator protection levels. When we conduct fit testing, we routinely see filtration efficacies on N95s well in excess of 99.5%+. Similarly, we've tested P100s with virtually no protection because of various failures. "Where can you go in a high quality, well-fit respirator" is the same answer: Basically anywhere. - While it is true that a PAPR does not need to have a seal/fit around the edge like a mask, PAPRs still need effective seals/fit (e.g., when installing the filter in the device, when ensuring components of the device are connected correctly, via ensuring the battery does not die to fail providing positive pressure, etc). All technologies - respirators, elastomeric, and PAPRs alike - require correct use and ensuring correct function... PAPRs are not an exception to this. Again, PAPRs are a great technology... but folks should be cautious with the information presented in the opening slides, which I worry risks being misleading.

Thank you

This is what I want for our family. We can't afford it right now, so we still just stay away from people, but this would give us so much opportunity to go participate with people. ❤ Thanks for sharing all of this experience and for doing what you do to stay out of the transmission chain.

It may be effective but it's not cheap!!!!

Just discovering this spray…on the point that was mentioned about e coli, is e coli a nasal virus?

I appreciate this so much. Thank you

Thank you for the video

Thank you

Does this product have an expiration date and how long can you use one bottle.

Thank you

Thank you!

This video has been paid by the manufacturer of this spray?

Just a heads up, I don't think the coupon codes are supposed to be displayed anywhere that is considered public.

I have a question: can profi be used after/alongside other nasal sprays like Covixyl?

Thank you for the video

DIsheartening to hear that OpenAeros went to "mask optional".

Can these PlusLife tests detect the new clades of MPox?

Kara, Thank you for sharing your journey through masking. Very creative. Excellent description of formal fit testing. I was a Chemical Engineer for 40 years, specialising in air filtration and masking. People have little understanding of masks or filtration. I wore masks of all types industrially. Fit testing flexible nasks is difficult. Your solution is excellent. For full and half face respirators formal fit testing is similar to your procedure as part of training. Informal fit testing done with every donning of the masks is easier. It involves using your palms to cover the air path in the cartridges and inhale. With the air path covered and no leak, the mask pulls in against your face. If it doesn't you have to adjust the mask and try again. Repeat as needed. With practice and experience, it is quick and nearly always passes on the first try. Be careful with the P100's (or N, or R). They are excellent, however the pore size is so small that moisture buildup inside the mask becomes quite a problem, quite rapidly. So does heat and CO2. The CO2 buildup can be minimized by learning to breathe differently - long slow deep inhalations and exhalations. This forces the trapped volume inside the mask out more thoroughly. Air pressure resistance is also a problem for a lot of people. Because of the moisture buildup (liquid), it is vital to wipe out and sterilize the masks after every use, and to periodically wipe them down with fungicide. There are lots of kinds of forced air respirators (PAPRs). The same criteria for fit and filtration efficiency apply. There is much more to know to truly understand filtration. One of the key ideas is called "most penetrating particle size". Air filtration works somewhat differently than liquids. There are four major mechanisms involved. These combine in an interesting way. If you plot efficiency versus size you see a particular particle size range that most passes the filter. At lower sizes, nearly everything is removed. At larger sizes the vast majority are removed. By layering two filter media with vastly different MPPSs, the efficiency is better, and flow resistance is less. By choosing different media with different charge and chemical characteristics removal is vastly improved as well. In total I spent the equivalent of about 5 years 24/7 "on mask. Like many of you I will mask for the rest of my life. I have 5 autoimmune diseases. I will not risk reactivating any of those, or adding a new one. As one more layer of protection... I do recommend you check on the recent science about second generation (non-sedating) antihistamines ability to bind to and block the virus. Obviously, talk with the doc about whether those are reasonable for you. Azelastine tested as having the strongest binding to the virus. This is not for everyone, and has risks.

This is so incredibly helpful! Thank you!

Thank you! 🙏🏼

Is there a link to the other more technical video that’s discussed in this video? And the Nature article that was mentioned?

Norizite (from Birmingham Biotech) is an iota carageenan spray that also uses gellan, so it traps like Profi does. just FYI. but Profi also sounds awesome, thanks for this.

Thank for you this discussion. I also subscribed to your channel because I'm still COVIDing and very few others around me are, so it's great to find likeminded folks!

Thank you for this Kara!

Thank you for this.
