That "lightning storm" smell is ozone—a highly reactive gas. And those machines she bought? They’re likely EPA Ozone Generators, often marketed as "air purifiers" or "air cleaners." Here’s the kicker: the Environmental Protection Agency (EPA) has a very clear warning about these devices. They are not safe for indoor spaces where people or pets breathe.
Wait, Isn't Ozone Good? (Like The Atmosphere?)
Yes, ozone in the stratosphere protects us from UV rays. That’s miles above your head. But ozone at ground level—the kind you breathe—is a lung irritant. Think of it like this: a little bit of chlorine makes a pool safe, but a big whiff of pure chlorine gas will ruin your day. Same deal, just less dramatic.
The EPA doesn’t beat around the bush: ozone generators should not be used in occupied indoor spaces. Period. They warn that even at low levels, ozone can trigger asthma, chest pain, and coughing. You know that feeling after a smoggy day? That’s ozone at work.
