| Cleaning virus particles from the air. |
| 2020-04-06 |
| By 3dc For this think adding sticky particulates in the air: Waiting for a friend from Chevron to post his analysis of aerosols of virus like this one. It's wild.... BTW best thing NYNY could do is park smoky diesel buses on the street filling the air with diesel particulates . Pollen is also good. Inside candles burning is good. The airborne virus particles have too much surface tension to vaporize and are too small to be stopped by HEPA filters. The clue was stewardesses getting the virus on long distance air trips. The air on planes is too dust free and clean so the virus makes it through the filters. BTW he is one of the top industry experts on filters and aerosols. Works at the big Chevron plant in Houston. Aerosols and filters including masks are among his specialties. In order of help least to best: 1) dust 2) burning candles 3) pollen 4) Diesel exhaust without CO. Then add HEPA filters and facemasks. Somebody asked what about hospitals - Perhaps they should intake outside air before their filters. The interior air should be mixed with diesel exhaust and purged from the building. As to store cashiers: If tobacco smoke is sticky - Maybe the checkout people at stores should be smoking cigars? |

| #11 UV is pretty good at killing everything that requires a microscope(and/or stain) to see it. Reef tankers have been using them in aquariums for years. One speed(of water flow) to kill algae, another to take out parasites and bacteria. It works (UVC, that is) by wrecking DNA, so if you go that route put it in a box. If you can see the light, it is mutating your DNA and you will have poor results as regards personal health. |

| #10 Doing the same Mike but all our units can be dialed down. If you only have an on switch and a timer, that's pretty bad. We started using Ozone over 20 years ago for mold and virus mitigation. Fantastic and simple. But again they have to be dialed down. |

| #9 Yes. In very controlled situations, has been used in vivo for pneumonia. And mites found in bedding (and on your face but not a brilliant cure for facial mites as the host suffers). Seriously upsets ants too, the hardy little buggers. They die but most seek new horizons. |

| #8 You grandmother or great grandmother would put a pot of water on the stove and set it to simmer. Add cup of vinegar white or apple. When you smell it, it kills it. |

| #7 Just in case it should ever become relevant, Whiskey Mike, does ozone kill bedbugs, too? |

| #6 I use an ozone generator. I rotate it between rooms. You CAN NOT be in the room when it runs. But ozone kills everything. It is a gas (obviously) and penetrates / disperses like a gas. Besides the upside of killing everything in the air or on exposed surfaces, or even into the mattress of a made bed you don't have to worry about getting all the air in a room through it like you do a filter. Plus it self quenches. Just don't let it be you that is the quencher. |

| #4 Shortwave UV, the stuff that kills the virus, is dangerous to eyes. Installing 'em just downstream from HVAC economizers may be an effective prophylaxis, however. |

| #3 I wondered about U-V light too. There seems to be some uncertainty as to whether COV-19 is airborne/windborne. There also seems to be uncertainty about the "viral shedding" mechanism of COV-19. |

| #2 Maybe UV light? |

| #1 What about ionic air filters for trapping the floating virus particles? Cleaning might take some precautions, though... |
