So, I live in a basement.

There's two windows in the basement.

So, the idea is that there's a bunch of old air that needs to get pushed out, and new air that needs to get pushed in.

So, I bought an air circulator off Amazon to move air around.

It takes in new air, and pushes out old air.

By doing this, it keeps co2 levels down. Cause, like, you breathe in oxygen and you breathe out carbon dioxide. Too much carbon dioxide makes you think slower!
