I am EXTREMELY skeptical. This looks like a slick marketing campaign and a way to fleece (understandably) scared people = scam! Where are the clinical trials, data and FDA approval? (None of this is on their website)? This looks to me like it is being marketed as Medical Device, which should be approved, but it is apparently not. Here is their disclaimer (from their website):
“The Company does not provide any medical advice on the website or along with the product, and the information provided should not be so construed or used. Using, accessing and/or browsing the website does not create a physician-patient relationship, and no information is to replace the services of a licensed, trained physician or health professional or to be a substitute for medical or advice of a physician or trained health professional licensed in your state. You should not rely on anything contained in the website and you should consult a physician licensed in your state in all matters related to your health. You hereby agree that you shall not make any health or medical related decisions based on whole or in part on information provided on the website or along with the product.”
Any time that I see "Harvard scientist" (who is not listed as faculty on their website but as an "Associate"), no data, and someone trying to sell something I am skeptical. This is probably about as effective as a much cheaper and equally ineffective salt gargle that people were pushing at the beginning of the pandemic (I wrote about this on my blog).
It would be a LOT cheaper and data shows to be a lot more effective to get some good N-95 masks, make sure that they fit and wear them instead of this expensive BS.
