Ozone (Odor Removal)

Tips for a Successful Ozone Treatment

The ozone generator we provide supplies about 5000 mg/hr of ozone output.  For effective and responsible ozone treatment for the purposes of odor removal, experts agree that the general rule of thumb is about 5000 mg/hr output for every 500 to 750 sq ft you wish to treat.  This is a lot of ozone, and should achieve ozone shock level (odor removal) for that amount of space within the hour (depending on the exact nature/origin and intensity of the odor).  You want to be careful not to go overboard when using ozone.  Too much ozone for the space may cause a strong ozone smell that seems to last for a very long time. Excessive ozone can also result in off-gasing of materials such as paint or flooring in the premises.  This is why we always advise a measured and incremental approach when using ozone, rather than aggressively “bombing” a space with very high levels of ozone all at once.

Cleaning is always jobs number one.  Do not use ozone as your sole effort.  For maximum results clean well, vacuum diligently, and remove built up residues on surfaces.  Ozone is TOPICAL working from the outside in.  So, embedded odors and deposits (like pet urine or many 0ears of smoking) are removable but they do not resolve with ease.  We suggest a layered approach that starts with the very best cleaning you can provide.  If the carpet is a problem, get it cleaned with special attention (spot treatments) of pet urine deposits.  If the walls are dingy with smoke, wash them but DO NOT PAINT OVER smoke odors until they are fully remediated (ozone should be implemented before painting).  Painting over smoke stained walls is a bad idea because that odor will leach out for years.

When you have done a good job cleaning, ozone will be able to work most effectively and efficiently.  Ozone touches every surfaces with enriched oxygen.  This is why ozone works.  The process is called oxidation where a free oxygen atom drops off and attaches to anything it finds.  Organic elements are the most vulnerable, so cooking odors, bacteria, smoke, and mold will be quickly impacted by the oxidizing process. During this process, a molecular change (oxidation) happens; and the end result is an oxidized form of the threat that doesn’t smell.  The best example you might recognize is rust (iron oxide) that has been changed from what is was into something quite different.

Again, we always advise to apply ozone is stages or increments.  Too much ozone for too long a period may produce some unwanted results.  Many things in your home were manufactured with a compound akin to formaldehyde to cure the product.  It is used in paint, glue, carpeting, stains, drywall, plywood, particle board, and your furniture and cabinets.  Using more ozone than necessary (excessive ozone) for your space can draw the formaldehydes out, the results is another form of aldehyde.

Reports of “The Ozone Smell” for days, weeks, and months after an ozone treatment means that the user went way overboard in generating ozone (most likely ran the generator for much longer than advised for the size of space) and something else happened during the process.  Toxins that already existed in the building were stirred up as the ozone tried to resolve them.  The latent health issue already there presents itself in a more overt manner.

The solution is to treat ozone with some respect.  Use common sense and follow the guidelines for responsible usage that we have provided.  You don’t go around liberally spraying bleach everywhere in your home, but used in the right amount it is a very effective cleaner and sanitizer.  Bleach is literally more dangerous than ozone.  Ozone is an enriched form of oxygen, and oxygen is a powerful element in our world.   When giving oxygen to premature infants, too much can cause blindness. The foolish or ignorant use of ozone poses some concerns that can easily be avoided with responsible use.


Use the ozone generator in short cycles of no more than 2 hours at a time, depending on the size of your space (remember, the generator we provide produces 5000 mg of ozone per hour, and that amount will treat aprox. 500-750 sq ft. per hour).  Then, evaluate the results.  A measured approach is highly recommended.

Apply it incrementally.  It is better to repeat the process if needed after first evaluating the results of the treatment  than to crush it with overpowering ozone for an eight hour period.

If you overtreat the area you may force out the latent VOCs in the building causing a long-lasting ozone smell.  Excessive ozone production for a particular space may cause off-gasing of building or furniture materials.  The rare occasion when the ozone smell does not go away as expected means that a factor existed in the home prior to ozone application.
