Ozone Sterilization for N95 Mask Re-use What say you? | |
| Anonymous Coward User ID: 78452873  United States02/10/2020 12:26 AM Report Abusive Post Report Copyright Violation | I have read a bit about the efficacy of OZONE regarding the killing of bacteria and viruses, so I went ahead and bout a 10,000MG/Hr Ozone generator and a nice sized clear plastic storage bin I intend to use as a sterilizing chamber. I've read many articles and it looks very promising. Quoting: Travis Bickle Here's one such article: [link to tuttnauer.com (secure)] So far it looks like the only issue I will have is perhaps over saturation of O3 on the elastic straps for the masks. If this thing TRULY goes off the hook in the coming weeks, many may be forced to "re-use" their masks due to lack of supplies. Which is a total NO-NO when dealing with viruses and such. Anyway, for what it's worth, I figured I would pass this info out to all of you and see if any of you have any other suggestions or see a problem with this. I'll be operating the generator in none confined spaces (Outside, maybe the garage with ventilation if it's rainy) and plan to pipe ALL of the concentrated Ozone into the box, thus saturating the masks for something in the 30 minute range. What do you think? (BTW, just about to get on the road for a 3hr trip so, I might not be seeing any posts until later this evening.) Stay safe everyone! Just buy a cpac cleaner. |

I just read some interesting news about that. I used to test filters, including masks like the N95 mask in a lab using controlled introduction of particles and particle counters to test filter efficiency, calculate mean pore size and loading/capacity of the filters. If you wet, spray, soak or steam that N95 mask, the fibers will shrink/expand or depending on the liquid used and the material used for the mask, may even break down those fibers. IMHO, this will make the mask less effective or perhaps not even at all. The Ozone generator is our approach too. If we need to decom a room or the entire house, car/truck we can. We plan to just isolate the Ozone to the mudroom so when you enter the house, you hang up your mask, googles and tyvek suit and shoes and seal the room up, run the Ozone generator for 5 to 10 minutes and let set for an hour We also own rentals so it's a good way to freshen up an old rental house. I think you are on the right track and it has multiple uses. Thanks for your input! Yes, I too know that the masks are designed as a "filter" and therefore wouldn't soak or spray anything on them. The Ozone should, (in a heavy enough concentration) permeate all openings and thus do a better job at sanitizing the mask with minimal damage or impact. Agreed The one thing that's counterintuitive about filters is that as they load, the mean pore size gets smaller which means they become more efficient. But the differential pressure sky rockets. For a mask, that forces air around the mask, not through it. So beyond just sanitizing the mask, you do have to worry about it loading up at some point. Once that happens, throw it away. If the situation is really dire, I'd hand rinse it, one direction only from the inside to the outside trying to "blow" out the particulate. Let it dry, then ozone it. Better than nothing and like others have said, a constant reminder not to fiddle with your face. How will you know, that's a hard call but if you find it hard to breath through the mask you are probably getting close. The timing will also depend on how much particulate is in the air, if it's high, it will load faster. |

| Anonymous Coward User ID: 78458431  Iceland02/10/2020 03:23 AM Report Abusive Post Report Copyright Violation | Remember, light casts shadows, the object would have to be rotating 360 degrees on all axis's or the air would have to be pulled past the bulb continuously. Quoting: BFD That's how ozone generators work. Yes this needs more work, the light does reflect so thinking 1. get some spray glue and foil 2. glue alu foil with the shine side to inside of box & lid 3. make a false bottom with some mesh, not glass, it has UV protection. I decided i wont put a vent on my box, I asume the O2 in the box will be converted to O3 ozone and after 15min of blasting, to vent it outside. PLEASE DO NOT BREATH Ozone, it will damage you. also avoid plants and pets. It will damage it or worse kill. Do not look at the light, its pretty but deadly! Atleast if you foil up the box you wont see the light. |

Meaning. What ever you wipe down, those rags need to be put in a container and sealed. glass bottle sealed? Again, consider baby wipes, they are cheap and you can soak them with your favorite option of sanitizer or disinfectant. there is some links if you google it. |
