If a smoker lived in your house, that smoke is embedded in the carpets, air ducts, and even the walls.

Pet urine

If a pet has done its business on the rug, even if the smell and stain fade, the odor will return whenever you have the carpet cleaned or the house gets humid.

Sink pipe

If the sour smell is coming from only one drain, the pipe under that sink could be obstructed. The bend in the pipe – called a P-trap – can collect hair, toothpaste, gel, dirt, and other gunk that will reek if it sits in there long enough.

The Water Heater

Check to see if your water heater’s anode rod is shot. Sometimes, a bad smell in the sink comes from the water and not the drain. Fill your sink with hot water. Let it sit for a minute, then put your nose close to the water and breathe deeply. If it smells bad, the culprit is probably the water heater.

How Does Ozone Remove Odor?

Basically, ozone removes odor 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 in 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 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.

With this in mind, it makes sense that a situation with a stronger odor (and more odor-causing molecules or particles) requires more ozone to remove the smell – there needs to be enough ozone to react with all of the offensive molecules it encounters. This requires either A) a longer ozone treatment or B) higher concentrations of ozone (a larger ozone generator). Check out this chart of common odors to see typical treatment times for common problems.

One common scenario involves people who have “tried everything” to get rid of a 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 that, 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. (source: http://www.ozonesolutions.com)
