In my various explorations of next-level masks I found this one on Amazon (Via Rolling Stone, the acting public health division of the US government ):
Currently $4/each with Prime. That price is typical for next level masks, prices are falling fairly quickly though.
Powecom shows up on the FDA n95 alternative list: Appendix A: Authorized Imported, Non-NIOSH Approved Respirators Manufactured in China (Updated: August 14, 2020) as Guangzhou Powecom Labor Insurance Supplies Co., LTD
We keep these for higher risk situations, such as visiting people even older than us (apparently they exist) or taking a drive share ride.
I think availability is rising quickly and prices are falling, I expect they'll drop below $3/mask in the next few weeks.
After months of seeking better masks we are now getting the sort of thing China has had since January. We are learning about our options not from the failed American state, but through the efforts of the last remnants of American journalism.
 Contrary to this article physicians reuse N95s. We wear them one day, leave them in a hot dry place for a week, and wear them again.
