There seems to be no shortage of N95 type masks at this point. For people who seriously want to protect themselves from getting Omicron for as long as possible (although personally, I believe we're all going to end up getting this eventually), that would be the way to go.
Even the reusable silicon half-face respirators from companies like 3M have started becoming available for sale again. When COVID got going, supplies were highly limited and most industrial & safety supply companies restricted sales either to existing customers or only verified health-care customers. Rather than having to throw out a mask every day, you can buy one of those for $30-45, another $15 or so for the filter cartridge (N100 or P100 work, and are even better than N95) which are good for quite a while before needing to be swapped for new filters. I picked up a fancy 3M HF-802SD from a local industrial safety products supplier my workplace regularly deals with. As far as half-face respirators go, that's their top of the line right now.
