@fergal_whatever @kprather88 Take hold from a single viron inhaled every single time? Seems very unlikely. The viron has to meet a cell. How does that happen 100% of the time?

@fergal_whatever @kprather88 每次都吸入一个病毒？似乎不太可能。病毒必须与细胞相遇。怎么会 100% 发生这种情况？

@fergal_whatever @kprather88 Not with humans. There is only a single reported human challenge trial where half of the (small number of) test subjects who all received the same dose became infected. Maybe with animals, but I'm not familiar.

@fergal_whatever @kprather88 不是人类。只有一次报告的人体挑战试验中，接受相同剂量的测试对象中有一半（少数）被感染。也许是动物，但我不熟悉。

@LazarusLong13 'Airline flights' why does that sound familiar.
Oh that's right.

@LazarusLong13 '航空公司航班' 为什么听起来很熟悉。
哦对了。

@DailyJLee @Walling_B @NanayCochran I'd bet a lot that it just stays green/yellow and can't get to orange. Which is mighty "convenient" for the bird's eye view because those rural counties are generally very large on the map.

@DailyJLee @Walling_B @NanayCochran 我敢打赌它只会保持绿色/黄色并且无法变为橙色。这对于鸟瞰来说非常“方便”，因为这些农村县在地图上通常非常大。

@MarvinH2_G2 @0bj3ctivity @3ris9 @RolandBakerIII She'll probably remove herself before long.

@MarvinH2_G2 @0bj3ctivity @3ris9 @RolandBakerIII 她可能很快就会离开。

@Ing30m @murchiston @FinchTH If the filter is on the intake side, air pressure will seal it well enough given a rough fit. That's been tested.

@Ing30m @murchiston @FinchTH 如果过滤器位于进气侧，则空气压力将在粗略的配合下将其密封得足够好。这是经过测试的。

@ghost_of_roger @twobluecats @lseward56 @DrEricDing If you're close enough to other people that you would smell a cigarette if they were smoking one, you should.

@ghost_of_roger @twobluecats @lseward56 @DrEricDing 如果您与其他人足够近，以至于如果他们在吸烟时您会闻到一支烟，那么您应该这样做。

@GainOfDystopia @FinchTH Right, so this thread.

@GainOfDystopia @FinchTH 对，所以这个线程。

@GainOfDystopia @FinchTH Not all homes use ducted HVAC either.

@GainOfDystopia @FinchTH 并非所有家庭都使用管道式暖通空调。

@GainOfDystopia @FinchTH Yes, for sure. But also doesn't fully address the need being suggested here. There are other spaces where people want to improve air quality. Offices, schools, retail, medical, etc. Often with limited or deficient HVAC and little or no practical ability to improve or modify it.

@GainOfDystopia @FinchTH 是的，当然。但也没有完全解决这里建议的需求。还有其他地方人们想要改善空气质量。办公室、学校、零售、医疗等。通常 HVAC 有限或不足，并且几乎没有或没有改进或修改它的实际能力。

@Lexisaurus @FinchTH @alexmeshkin The precondition for that determination are various types of emergencies (military, homeland security, health).

@Lexisaurus @FinchTH @alexmeshkin 该决定的先决条件是各种类型的紧急情况（军事、国土安全、健康）。

@jaystarjo @FinchTH You can probably raplace their cheap MERV10 filter with Filtrete 1900 MERV 13 which has lower pressure drop than many less-effective filters.

@jaystarjo @FinchTH 你可以用 Filtrete 1900 MERV 13 代替他们便宜的 MERV10 过滤器，它比许多低效过滤器具有更低的压降。

@ChloeLum @bearonwings @FinchTH It reports air quality as a graph on your phone and you can turn it on and off remotely.

@ChloeLum @bearonwings @FinchTH 它以图表的形式在您的手机上报告空气质量，您可以远程打开和关闭它。

@Ing30m @FinchTH It's this. Slightly more expensive (filter is about $100) but not much.
https://twitter.com/AeonCoin/s...

@Ing30m @FinchTH 就是这个。稍微贵一点（过滤器大约 100 美元）但不多。

@FinchTH @Rod_Crestwood 600-850 CADR in this peer reviewed paper. I think the Air King fan may be slightly better than the ones people get in big box stores.

@FinchTH @Rod_Crestwood 600-850 CADR 在这篇同行评议的论文中。我认为 Air King 风扇可能比人们在大卖场买到的要好一些。

@ewrigleyfield @FinchTH This DIY design using Lennox X7935 for the filter has carbon in the filter. How effective it actually is for gasses/odors, I don't know. It's been tested and is very effective for particles.

@ewrigleyfield @FinchTH 这个 DIY 设计使用 Lennox X7935 作为过滤器，过滤器中有碳。我不知道它对气体/气味的实际效果如何。它已经过测试，对颗粒非常有效。

@FinchTH If the idea is pathogens, and minimizing floor space, a ceiling fan with upward-pointing UVGI (not far uv which doesn't seem ready for prime time) might be better?

@FinchTH如果这个想法是病原体，并最大限度地减少占地面积，那么带有向上指向的UVGI（不远处的紫外线，似乎还没有准备好迎接黄金时段）的吊扇可能会更好？

@FinchTH The dirt cheap DIY option is a fan with a fat high-pleat-count filter attached to it with rubber bands. Of course you can manufacture a product but this gets the job done with no duct tape.
https://twitter.com/Read4Ks/st...

@FinchTH 便宜的 DIY 选项是一个风扇，上面有一个用橡皮筋连接的脂肪高褶数过滤器。当然，您可以制造产品，但无需胶带即可完成工作。

@Pravduh15 @DrEricDing Even in a home most commercial air purifiers are underpowered and/or very expensive. But either way can work, it just requires bigger/more air purifiers than people expect or buy and costs more.

@Pravduh15 @DrEricDing 即使在家中，大多数商用空气净化器的功率也不足和/或非常昂贵。但无论哪种方式都可以，它只需要比人们预期或购买的更大/更多的空气净化器，而且成本更高。
