‘Modern construction creates perfect virus chambers.’
Modern buildings are designed to trap heat, reduce airflow, and recycle the same air over and over again. These choices weren’t made for health, they were made for efficiency.
When a virus that spreads through the air arrived, it moved easily through the spaces we had created. Classrooms, care facilities, workplaces… all became high-risk by design.”

By the time COVID arrived, this knowledge wasn’t lost, it was documented. We had decades of research explaining how respiratory viruses spread, and a full century of lessons from past pandemics.
But instead of applying what we already knew, we sealed ourselves indoors and treated airflow as an afterthought.”

In 1918, doctors didn’t have advanced medicine or modern technology. They had observation, urgency, and a willingness to do what worked.
They noticed something simple: people got sicker faster indoors, and recovered better when they could breathe fresh, moving air. So they opened the windows.”

In 1918, doctors did something obvious. They opened the windows.
It wasn’t complicated technology. It was air.”

The filter furniture has computer fans on the front and back, to draw air through the MERV13 filters. From one end you can see through to the fans on the other end. 

The Nukit Lantern also has a mmWave motion detector, to try to protect the bulb from burning out when no one is there. You can see it dangling off to the side, but surprisingly it still picks up a lot of motion even when not facing the right way.
