content: Ionizers will knock aerosols out of the air pretty quickly, so it can probably reduce aerosol infection (with the caveat that it's still not know for certain if aerosols are a significant pathway of infection for corona).Getting a small negative charge will however not inactivate viruses and their claim this isn't an ionizer is clearly bullshit.PS. actually it seems I jump to conclusion,chargedviruses can be substantially inactivated after they are captured and discharged. It's still just an ionizer though.PPS. not a fan of metal tips for ionizers, require too much voltage and they don't erode gracefully.

content: Very expensive ionizer sprinkled with a dash of pseudoscientific woo-woo - and nothing more. With the caveat that it isn't known whether ionizers actually do much with the covid-19 (as opposed to UV lamps, ventilation, masks and so on).You would probably do equally well or better by simply opening windows and ventilating the room. And also having everyone wear masks indoors, whichareproven to significantly reduce the amounts of aerosols in the air. Plus you won't get exposed to ozone and other nasty stuff that ionizers generate.See e.g. here:https://phys.org/news/2021-03-uncovers-safety-air-purifiers.htmlThat gadget is just preying on the desperate and not actually effective means of combating covid.Quote from: Marco on May 15, 2021, 04:12:00 pmThere is plenty of evidence that aerosols play a major role in spreading Covid, pretty much since the start of the pandemics already, especially with the asymptomatic/pre-symptomatic people who aren't coughing and sneezing (and thus generating droplets in any significant amounts).See e.g. this analysis:https://pubmed.ncbi.nlm.nih.gov/33153155/"Our results suggest that aerosols from highly infective subjects can effectively transmit COVID-19 in indoor environments. This "highly infective" category represents approximately 20% of the patients who tested positive for SARS-CoV-2. We find that "super infective" subjects, representing the top 5-10% of subjects with a positive test, plus an unknown fraction of less-but still highly infective, high aerosol-emitting subjects-may cause COVID-19 clusters (>10 infections)"

content: Quote from: janoc on May 15, 2021, 06:38:51 pmNot really ionizers ... trying to push both electrons and positive ions into the air is a stupid idea, they'll mostly just recombine. It's not going to be nearly as effective in giving particulates negative charge and making them precipitate on neutral or positively charged surfaces.I wouldn't be surprised if all the VOCs were simply a result of the thing heating up when operating.

content: Ozone will obliterate viruses though as it oxidises the membrane. If it generates enough ozone from ionizing it would be effective, but you wouldn't want to breath in too much ozone.Has anyone tested it's ozone output?

content: Quote from: Cyberdragon on May 15, 2021, 09:56:57 pmNo kidding. If it generates enough ozone to kill airborne viruses in a room, then your life expectancy if you are in said room will probably be pretty short. I guess you'll wish you had caught a virus instead.

content: They tested it themselves and measured no ozone.I choose to believe them, cold field electron emission can happen at field strengths below what's needed to create ozone.

content: I think we had this before.AFAIR this *does* work as advertised; by electrically charging up the aerosols and particles, they will cluster up and are easy to filter out. Virii react quite sensible to the environment, clustering them will effectively kill them. A good (mechanical) filter ist still required.It is built like an ozone generator, but with a little lower voltage, just below creating ozone.

content: Even without a filter they will be pulled out of the air ... and onto everything. The walls near that device are going to get dirty.
