We still have them... Making sure they are charged in case we have to go out.
I have several 850 CADR HEPA 13 air filters in the house, that are keeping the indoor air under AQI 25 in all this smoke. They usually read about 5 or 6 on smoke free days.
These are those portable HEPA 13 powered masks:

Good. I hope you don’t need them.
