I've cleaned the filters twice since the start of winter.
Right now, they still look pretty clean.
I'm about 99% sure they aren't holding any COVID19,
however I'm going to leave them alone until Spring maintenance around May.
No one but immediate family has been inside our home in the last 30 days.
My kid gave me her cold, and that seems to be all it was. It's gone now.
So far, no one in the family shows any sign of COVID19.
The Boston area is getting hit now, so we are about to go to Shelter-in-Place.
The kids are working from their home this week, and that might become a long term thing.
