1 (of 2) HEPA filters replaced (only 1 new filter of the correct size was available)
Grating from all trays sifted + vacuumed (pre-filters and charcoal)
Inside of filter box vacuumed, and remaining dust from nooks & crannies removed via damp rags
There were lots of HEPA filters nearby the filter box (and in the furnace room), but they were of too narrow a size to be used. The current configuration of the filter box had two HEPA filters, so one of them still needs replacing.
The filter packs come in 3’s from Home Depot. I usually just buy a new package of Hepa filters from Home Depot before changing the filters. It beats having the filters lie around for three months then go missing at VHS.
We should get a completely new set in there as it will help keep the air inside VHS cleaner which is important for those folks with breathing sensitivities.
A couple of questions.
Did you get a chance to check the seal around exhaust pipe in window?
Was all the activated charcoal changed completely? l.e. all new charcoal for all the trays?

Nope; wasn’t aware of this.

We didn’t – we weren’t sure how much charcoal is normal, but all trays were already at least 50% ~ 66% full, and (after sifting + vacuuming) still looked very dark black and pellet shaped.
