Being outside earlier today was awful, I had an appointment I couldn't miss, but I've got a MERV13 filter in my HVAC at home running non stop to circulate and filter, one HEPA filter on each floor of the house, and one in my office. Indoor AQI got up to 40 downstairs yesterday so I set all the purifiers to max overnight and I'm down to 10-15 this morning. We are not going outside today lol staying in our safe little bubble
