Just before indoor “shared air” exposure I 1st spray home mixed antiviral 12% xylitol in PLAIN sterile filtered water into my nose and mouth to saturation and the need to blow my nose. (a scant tsp xylitol in a 30 mL nasal pump type fine metered spray bottle such as “Snoot” brand) I use birch xylitol. Cleans nose - improves biome - reduces viral binding - antiviral activity. Plain water, not saline, seems best here per published research and confirmed in a Steve Kirsch interview with the head of Xlear, a company that produces and sells products with xylitol.
Then a few sprays of home mixed antiviral 0.5% povidone-iodine in sterile saline breathed deep as sprayed into each nostril and mouth and from a bit of a distance (aiming between the eyes at bridge of nose) a couple of sprays on to open eyes and eye area. (1 part povidone-iodine solution 10% to 19 parts saline solution note: some prefer a 1% mix 1 part povidone-iodine to 9 parts saline) Kills the damn virus. I choose more sprays, 4 into each nostril and into mouth of 0.5% (perhaps I will go to 0.6% as 1 study found more effective than 0.5%) for perhaps better wetting and coverage vs fewer sprays, ie. 2 sprays of 1%. I ignore trials started 5 days after testing positive, perhaps 10 days after infection that show no benefit. Probably offers good protection up to 3 hours. 1 study showed viral killing was gone at 4 hours. I found one hospital system mixing it, 0.5%, fresh every day out of concern that in solutions less than 1% the iodine, over time, may be released from the povidone bond. I understand this would make the iodine stronger and more irritating as free iodine dissolved out of the povidone. note: in Japan a 0.23% formulation is marketed. They were using it in the hospital 5 times over the course of the work day from just before starting work to just after finishing work. I give it a good shake before use, I mix a little at a time and use it up, if I had older solution and found it irritating I would mix up a new bottle. I have found the 0.5% very easy to use.
I started out from Dr George Domb, ENT Redding Chico Eureka if it does not stay visible, refresh and rapidly click on the page as it momentarily appears. He used 1/2 tsp povidone-iodine solution 10% in a 44mL squeeze bottle of saline nasal spray. His cautions for its use (for prevention) “Do not use it if you are pregnant, breastfeeding, have hyperthyroidism, are being treated for thyroid cancer with irradiated iodine, or hypersensitive to iodine. It should not be used on children younger than 6.” I, personally, would certainly use it for all at the first sign of possible covid infection.
I wipe the spray nozzle and inside of the nozzle cap with a piece of tissue damped with a bit of bleach and clean out the spray bottle and sprayer using 70% isopropyl alcohol , spraying with the cap on loosely to rinse it out and shake out the bottle and spray out the sprayer then air dry before refilling. Xylitol in plain water will support mold growth spots inside the bottle. Before refilling I put a bit of bleach solution in the bottle put the sprayer back on the bottle, shake, spray let it sit a bit then rinse with sterile water
After the xylitol and PVI sprays I put on a 3M N95 and add the side shields to my normal looking safety eye glasses - any eyeglasses help. Comfortable breathable 3M “Aura” 9205+ N95 with weak straps that break or the Aura 9210+ with probably stronger straps, both which fits the most people and which have a filtration efficiency of, see test # 644, . Keeping out 99.68% - “total leakage” through and around the mask - of salt test particles with a median size the size of a smaller single sars-cov-2 virus and within the salt test particle mix particles 30 times smaller and twice as large approximating the size of a larger single sars-cov-2 per wickedpedia sars-cov-2 size data . see Aaron Collins testing masks on youtube. Also see there how easy it actually is to adjust N95 masks for fit. I also use the 8210+ with a filtration efficiency of 99.80% see test # 636 because it is so easy to put on and take off fast and wear for a few minute “encounter” for protection from the curb side pickup “close talker” or cough or sneeze in the face. Aaron Collins has said the 3M™ VFlex™ Particulate Respirators 9100 Series was his “new favorite” because it is exceptionally breathable. It is also the lowest cost and available in 2 sizes. Mask test data available here Master Mask Testing Data Set - Google Sheets note: the electrostatic charge fills all the space between the fiber of the masks so that very tiny particles with little mass are easily captured by the electrostatic charge which draws the fine particles to the fibers and sticks them there. These may also be quite effective against tiny toxic “shed” particles. note: the 95% rating is against a larger, heavier, “most penetrating” size and mass particle.
After indoor “shared air” exposure, when back home, depending on perceived risk from infected shared air exposure, I use 1% Johnson’s regular “no more tears” baby shampoo in sterile saline for nasal flush using a NeilMed 8 ounce nasal flush bottle, for eye wash from palm of clean hand or eye wash cup - blinking a lot and for mouthwash/gargle. (1 tsp/5mL baby shampoo per ~16 ounces/500 mL saline) then, as you will, a few sprays of PVI. The baby shampoo in saline is a viral killer and good cleaner. I may also nebulize a few mL (8 ml?) of regular vodka - easy to do after a few partial “diluted” 1/2 breaths. I use the Philips respironics “InnoSpire Elegance”, no prescription needed from some on line suppliers, low cost 100% duty cycle . I think this would be better, easier to breathe, if enough “saline mix” was added to the vodka to convert the 60% water fraction in the vodka to normal saline. note: A anti-covid ethanol nebulization study states that nebulization creates such tiny particles that the ethanol and water separate by rapid evaporation into very high percent ethanol and water. note: I think that if the right amount of baking soda / salt saline mix was added to dissolve in the water component of vodka, in addition to outright killing of the virus some additional inhibition of viral cell entry and inhibition of viral replication in the cell could be possible. note: Nebulation is a key to therapeutic delivery of covid-19 prevention and treatment including, per Dr Zelenko and David Scheim PhD, hydroxychloroquine where as few as 1 or 2 pills worth of HCQ nebulized almost immediately builds the therapeutic effect, and more, of a full course of pills without potential systemic side effects or contraindications.
For saline I use 1 part baking soda 3 parts salt which is close to the NeilMed formula for saline mix.
(by measuring a couple of NeilMed saline mix packs) to make 2 cups/16 ounces/500mL 1/4 tsp baking soda 3/4 tsp salt. I boil the water from a 500 mL bottle of filtered water for a few minutes, let it cool down then add the baking soda and salt. I let it cool till just warm because heat chemically changes baking soda.
IMO Very much worth the effort for the high risk. Actually simple after a routine has been established. Most all may actually be at risk over the long term from some “spike” pathology even from “mild” covid and also from the spike “vaccine” antigen.
ps. the 2 times per day nasal flush study that reduced hospitalization of covid sick older high risk people by 8 times added either 1/2 tsp of povidone-iodine solution 10% OR 1/2 tsp of baking soda to 1 cup/8 fluid ounces of “normal” (NeilMed) saline. Both the povidone-iodine and the alkalizing baking soda mix worked ~ equally well.
