One common question that people have about using ozone is exactly how an ozone machine is able to remove odours from houses, cars, clothing, etc.
Basically, ozone removes odour by destroying the molecules, bacteria, and spores that cause unpleasant smells. Ozone (O3) is a highly reactive molecule and is very quick to chemically react with particles that it comes into contact with the air and on surfaces. The extra oxygen atom in the ozone attaches itself to other molecules, chemically changing their structure to create non-offensive molecules – eliminating the smell
When considering bacteria and mould spores the same process applies, with ozone attacking the outer shell of the cell causing it to break down. When the outer shell degrades, the cell itself breaks apart and dies.
One common scenario involves people who have “tried everything” to get rid of the smell but are still left with lingering scents that just don’t seem to go away. One reason that ozone is effective in these situations is because, as a gas, ozone effectively “cleans” any place that air can go. This includes air, walls, ceilings, ductwork, carpet fibers, gaps between floorboards, cracks in walls, and more. Ozone is able to penetrate into these areas and destroy odors that it finds there.
So how does ozone get rid of smells? It chemically breaks down odor-causing molecules in any area where the air is allowed to flow.
