Odor Removal with Ozone Generator

When it comes to odor removal, there are a few basic solutions.  Mask them with fragrances, filter the air, or treat the odor at the source.  We already know that fragrances are only a temporary masking device.  Every room deodorizer company silently rejoices about temporary solutions since it means a repeat business that never fades away.

Filters are only modestly effective.  They can clean the air that passes through, kind of ...  Most filters are not made for gases, but particles.  So, filters don't do the job as well.  

Ionic filters use a magnetic charge to cause very small particles to agglomerate (cling together) making them larger for filters to catch or heavier so they drop to the floor.  A good idea, but not as effective as a real odor problem requires. 

Nothing reaches out and literally attacks the odors where they live.  But, ozone does!  Ozone is a gas made with three atoms of oxygen, and the extra atom of oxygen easily discharges because it is unstable.  When the oxygen atom singlete drops off, it attaches to whatever threat it finds.  The oxygen atom then oxidizes the threat.  This is a molecular change that nullifies nearly any odor threat you can imagine.  Oxidation is like rust is to iron.  Rust is different than iron, but imagine doing this to smoke odors?  

Ozone is part of nature itself.  It is chemical-free and does not pollute.  So, this process would seem a thousand times more effective than cans of fragrance that deposit more chemical throughout the house.  Ozone is made from ambient oxygen (O2) that is converted to ozone for about twenty minutes until it reverts back to O2 again.  No resource depletion and no waste left behind.  It is the most effective odor treatment and sanitizer in the world.

So, the conclusions is pretty obvious.  However, there is more to the best uses of ozone.  There are a myriad of ozone generators on the market.  All of them making bold claims of effectiveness.  Most of these system are the 5000 mg/hr or so machines that are using dated technology, but promoting their units as though they were miracles in a box.  Well, here is the professional opinion on odor removal with ozone generators.  Professionals use massive amounts on ozone (ozone shock) for short durations of 3-6 hours to treat embedded odors.  Smaller equipment (if you find the facts buried on the website somewhere) suggest running their smaller machine for 12, 24, 48, and 72 hours to get results.

Ozone always works, it is the techniques used that make ozone work best.  Rather than prolonged ozone treatments, it is better to use cycles of intense ozone applications until the odor is gone.  Think of odors as layers.  Some odors will resolve in one 3-4 hour period of ozone shock.  Others, will take three or four of these treatments.  These extreme examples, however, are for really bad problems.  Unattended dead odors that are left behind, hoarder homes, and even the "renters from hell" odor problems.  The average family will do well with a standard 3-4 hour ozone shock treatment.

Ozone shock means pushing the ozone PPM levels above 6 PPM, which is a heavy ozone treatment.  People and pets cannot stay in the house during the treatment because ozone is a respiratory irritant.  After the treatment, the ozone is dissipated, and the "Pool-like chlorine smell" fades away quickly.  If a second treatment is required, it is because odors are embedded in carpet padding and fabrics.  

To be clear, ozone does not make thing "Like New", and they are rarely 100% effective.  Ozone is considered a success if there is a 90-95% improvement.  This is because houses and building are living spaces that are filled with the residue of our lives.  Dust and dirt are still throughout the house.  Animals and people return to the building.  And, daily activity is never pristine.  So, be realistic about ozone.  It is a tool, not a miracle.  View it much like other cleaning products.  They improve our lives, but our lives are in constant need of upkeep.  

So, use ozone as an annual treatment like it was a "Spring Cleaning" program.  To make the most of an ozone treatment, do your best cleaning before ozone is used.  Vacuum carpets well, clean and scrub everything you can reach.  Ozone works best when it is used after cleaning.
