Don’t poz yourself, China is the only country in the world where you aren’t virtually guaranteed to get infected (although this may change). There is brain damage at stake. I don’t know how dangerous the current strain is, since most people in China have little herd immunity (and Sinovac’s contribution is unclear) and hospitals might be overrun.
In the US, the standard is P-100 masks which were recommended for SARS in 2014. You can get them at the hardware/construction store and they look like this (they are not electric and cost $10-15 at the hardware store in the US, probably more like $200 in China if they’re in stock at all, but one mask will last >6 months):
N95 and KN95 masks probably don’t work very well.
If you’re in an apartment, seal off the ventilation system by covering it up with a layer of Duct Tape, and use windows and a plug-in heater instead. If you share a door with a hallway, attach a fan to your window and have it blow air in whenever you open or close that door so that the hallway air does not enter.
Lastly, this is things you can do for people who get covid, yourself and others. I have no idea how many of these are available inside China, but the list is ordered properly.
Sort of! They don’t plug in or use batteries, but they do have an electrostatic charge which they use to catch small particles.

Why do you say this? For example, while microcovid is very negative on cloth and surgical masks they think N95 or similar are decent (and worth wearing if risk is not that high or you can’t get a better one): https://www.microcovid.org/blog/masks
Yeah, I just had a family member tell me that he was going to work while he’s pretty sure he has definitively tested positive for COVID. The symptomatic kind. This type of thinking doesn’t seem to be unusual among the people I know.
I don’t know how things are going to go, but people seem to have zero hesitation about causing super-spreader events if the alternative is interrupting their routine.
Not looking so good. I just don’t see how I don’t get infected in 2023 even if I take all precautions possible. If 20% of my office have active COVID infections in, say, February, how much does P100 help? I also prefer sporadic COVID infections for the rest of my life over perma-masking and no dating.
Thanks for the advice though. In hindsight, I will tape up the ventilation system in my apartment. It’s actually really gross since it’s in the bathroom and I can actually hear my neighbors through it.
Unlike disposable masks, P100 masks (found in the dust mask section of construction/home improvement/Home Depot/Lowes stores) are heavier and much less comfortable to wear for 8 hours. However I might be wrong about that because the structure of my face is unusual.
It might be worth it to look at the seal of the mask and see how sharp it is. A softer rubber edge, with a larger surface area, is more likely to be comfortable if you wear it all day (with a break every hour). I’ve worn 3 p100 masks total and two of them were pretty uncomfortable to wear for more than an hour. The key is to go outside, eat outside whenever you aren’t wearing it, to take breaks once every hour, and idk how cold it is in your city. It’s also hard to talk and be heard when you are wearing them. They’re an absolute must for crowded places though, and most people don’t know that the government/military actually have several capabilities that could theoretically allow them to halt the spread of the virus at any time, even at 30% of the population (especially when combined with targeted lockdowns), but the technology is new and secret so the odds of success are unclear. Furthermore, some of the strains might be mostly harmless and mainly give people immunity (like a vaccine), or might already have done so, maybe to 40% of the population for example. So it’s too early to tell whether it’s futile to avoid the current strain.
An elastomeric respirator or PAPR paired with N100-equivalent filters should provide the best available protection and should significantly reduce risk.
Here’s the reasoning:
You can’t get anything that can filter out more stuff short of using an oxygen tank.
There’s more recent quick-and-dirty evidence for covid and disposable N95s here. There might be even more such evidence, but I haven’t looked for it.
Elastomerics and PAPRs can provide more protection than disposable N95s.
Even if some tiny amount of virus aerosols penetrate the respirator, it would still be extremely difficult for them to actually produce an infection due to the different hoops they’d have to jump through (i.e., they would be extremely diluted, have avoid sticking to the walls of the respirators, and then have to reach the right cells and avoid getting stuck in mucus).
You could use a respirator until you get access to a better vaccine or other effective therapeutics.

Here’s the reasoning:

There’s some empirical evidence suggesting that elastomeric respirators have provided adequate protection for health care workers in a TB ward, whereas disposable N95s might not provide adequate protection in similar circumstances.
