Agreed. A Rivnut is held in place by a very thin top flange. A 1/4’ drill bit (or slightly larger) bump on the top flange and it will just fall out.

Retro-fitting HEPA filter in Model Y

Got it installed today. The holes didn't actually line up perfectly so it took a little finessing to get the bolts in. But I did get it on and aligned to wear it needs to be. I also ended up cutting off the alignment tabs from the the part rather than cutting holes into the car. Works great. Now I just need to convince someone at a service center to give me the software button…
Just a heads up. I also have the Unplugged Performance Dirt & Snow Adjustable Coilovers installed. There are knobs on top of both suspension areas to adjust the firmness of the suspension. With the HEPA retrofit they're still accessible but it's not as easy to adjust them as before. Espeicially the one on the right side under the windshield wiper fluid intake.

I did the retrofit on my ‘21 MYLR last year when this thread was starting. Thank you everyone for posting the part numbers. I was not able to convince them to program the car with the BioDefense mode after installing it but today I took in my car to replace the 12V battery and asked before I left if they could program my car to include BioDefense mode. The service manager was really cool and told the service tech who was helping how to write it up on my ticket. It did cost me a whole $10.50 to have them reprogram my car but now I do have BioDefense mode! Pretty stocked that I could install this and have them upgrade the software!

That’s awesome you got the button added! Just had service appointment today for something else and asked as well about the button but they said they could not. Will just have to try again next time I need service I suppose 
Just submitted an service request for the parts via mobile service and got this reply:
Looks like it’ll be an uphill battle to get the BWDM software setting/update. A previous request that included the BWDM item was rejected, and after some back and forth they said I could order parts, so I guess at least there’s that.
It does seem silly they won’t charge like $50 and update the software, unless there’s some legal or liability thing.

I give up, service center will not order parts since my car did not come with HEPA from factory. I kept requesting to please order but they stopped responding to my text via the app.
Where exactly were the tabs you ended up cutting off? I just retrofitted the HEPA filter on a pre-threaded hole 2020 built MY, and didn’t see anything that seemed like it would need to be cut off or needed holes drilled? The filter is a different model number now so I wonder if they’ve changed it.
Please report back! I already did mine but would be cool if they’re officially doing them now. I doubt it’ll be free, though

Sure, I will report back. In fact, they changed the date and told me they are missing parts and payment estimate is wrong. I think the reddit poster got lucky. I told them my parts are already installed, I just need the button, they then changed the appointment to next Thursday and changed payment estimate to $153…. I don’t think software configuration should be $153. I will try to talk it down in my appointment.

Given other hepa retrofits were $500, you’ll still come out on top to be fair…
Well, I already paid for parts and DIYed the installation. The button is just an OCD thing, will I pay $153 for OCD? I think it will depend on my mood during the appointment.

Parts were around 200-250 right? I got lucky getting the button for free, but personally I would paid $150 for it.
Reporting back. Today I was waiting in the car and the fan felt extra strong. I went to turn down the Fan and saw the Biohazard button! Yes! Tesla did it remotely and free of charge. There is also a message in my Tesla app from a nice technician explaining that the work has been done and no need for an appointment. If you haven’t got the button, now it is time to message Tesla.
