When you hear the word ozone, you probably think of the layer in the sky above us that helps filter out ultraviolet radiation from the sun. But it is also a molecule used in some air purifiers because it effectively reacts with and eliminates strong odors and airborne chemicals. The ozone can naturally turn a bad smell into a good one. But before you buy an air purifier or generator that uses ozone technology – you should understand what you’re considering and know the dangers.

Better Smelling Air with Ozone – But is it Safe?

Ozone is a molecule composed of three atoms of oxygen. It is an unstable molecule that reacts with anything it bumps into. The chemical effectively removes odors and kills mold and mildew because it can react with and break down anything it comes in contact with. Unfortunately, the very thing that makes ozone so effective at removing odors also makes it dangerous. If it is present in high enough concentrations to eliminate bad smells, then it is also reacting with your skin, eyes, lungs, and other exposed areas and causing harm. It has a pleasant smell, but if you can smell it, it reacts with you and can cause long-term damage to your respiratory system.

What are the Side Effects of Ozone Exposure?

If it’s inhaled, ozone reacts with compounds in your body and can harm your lungs. Even small amounts of ozone can cause coughing, shortness of breath, chest pains, and throat irritation. Ozone can inflame and damage your airway, make your lungs more susceptible to infection and aggravate existing breathing and lung conditions. It can even increase asthma attacks and cause Chronic Obstructive Pulmonary Disease or COPD. Everyone is at risk, but anyone with asthma or certain vitamin deficiencies, children or older adults has a greater chance of exposure problems. The longer you are exposed to ozone, the worse the damage to your respiratory system will be.
