Yup yup yup! The lack of investment in air purifiers/ literally moving classes outside in warm areas continues to show me that most of America is painfully stupid about air quality.
To this day, Americans hatred of air purification is so strong that they will actively spread FUD about how “stronger filters in your furnace filter are bad cus it’s not supposed to filter air and it’ll make your machine work harder”. As it turns out, an enormous amount of poor air quality comes from all kinds of heaters.
Americans deserved to reap what they sowed here. I lost a whole lot of my sympathy/empathy for my countryman due to this. I regret that I didn’t switch to one-way masks as a way to further revel in the low trust of my society.
