Short term? Cough, chest tightness, throat irritation. Long term? Studies link repeated ozone exposure to reduced lung function and even permanent scarring. You wanted a clean room—not a jury-rigged chemistry experiment.
I love that ironic moment when someone says “I can smell how clean the air is.” Newsflash: clean air has no smell. If you can smell it, you’re inhaling an irritant.
But the marketing says “green” and “chemical-free”
Oh, they’re masters of spin. “No chemicals!” they scream. But ozone is a chemical. It’s three oxygen atoms in a grumpy mood. Calling it “natural” is like calling a sunburn “natural skin improvement.” Technically true, but you’re still hurting yourself.
Look at the fine print: the EPA specifically warns against using these devices in occupied spaces. Yet they’re sold as home air cleaners. It’s like selling a flamethrower as a “rapid air freshener.”
