J Murphy, Sr VP of Operations for Paul Davis National, tells his personal story of the Odorox vs. Titan experience:

“...we fell victims to the “you get what you pay for” syndrome. Not knowing much about hydroxyls, we thought any machine that said “hydroxyl” was the same, so we bought 4 Titan 4000 hydroxyl generators. Our first use of the Titan units was at a factory fire…After 24 hours, there was little to no change in the odor…so we let the units run for another 24 hours. Again, little to no change. We didn’t get to charge for the use of the Titans as the adjuster ended up total-losing the entire inventory of fabric…”

“...From that experience, we purchase a few Odorox XL3s and placed them on a fire project at a University…The XL3s worked like a charm! It was at that point that we became believers that hydroxyl and XL3s were the perfect combination…we purchased 30 more units to up our inventory to 60 units…I believe this equipment is a game changer in the restoration industry – it is for us!”

Odorox® - very simply, it’s the original hydroxyl generator first introduced to the Disaster Restoration Industry in 2008. It is Patented, Scientifically Confirmed, and Safety Tested by highly reputable independent labs. Odorox is the number one tool used by contractors to eliminate odors on all projects, no matter how large or small they may be. Odorox® eliminates any odor, any place, any time. Just plug it in and do your normal work. Yep, it’s that simple.

Ever use the Titan machine? Did you find it didn’t work? We hear that all the time, and even independent expert labs confirm this point.

Lovelace Respiratory Research Institute (LRRI), with the assistance of the leading atomospheric hydroxyl radical expert Dr.. David Crosley, tested and compared Odorox® vs. the Titan 4000 to see how many hydroxyls each produce. Odorox® was very impressive showing an 18% reduction in the VOCs in just a 2 hour period, and a measurable quantity of approximately 2,000,000 hydroxyls per cubic centimeter. (link to LRRI test results). Significant VOC reductions by Odorox® were also shown in the independent tests by Michael Pinto and Wonder Makers Environmental, Inc. that was done in a post-fire environment.

On the other hand, the exact same LRRI testing of the Titan 4000 showed that it did not reduce the VOCs at all, and therefore produced no measurable quantity of hydroxyl radicals. Nothing! LRRI decided to create a second test using a much easier VOC for hydroxyls to break down. Again, they got the same results – Titan showed no measurable reduction whatsoever!

It gets worse. The testing was done in a highly controlled environment and the humidity was 58.4%. When these results were released by LRRI, the manufacturer of Titan said it needed to have 60% humidity for it to work. Seriously?!? After more than 5 years, the Titan 4000 still hasn’t had one single test performed to validate that it effectively reduces any VOCs or that it produces any hydroxyls. Hmm, we wonder why….

How the research and science stack up

According to research conducted by the Lovelace Respiratory Research Institute (LRRI):

  • Under highly controlled conditions, there was no evidence that the Titan 4000 was producing hydroxyls using published analytics methods capable of measuring hydroxyl concentrations as low as 5-10 ppb. The Titan is unable to produce any measurable quantity of hydroxyls and was unable to make any reduction to either of the test VOCs in the air. 
  • Under the same highly controlled conditions, the Boss™ system generated hydroxyl radicals which rapidly reacted with n-heptane producing a measurable reduction in the n-heptane concentration consistent with a hydroxyl formation rate in the hundreds of ppb.
  • The average concentration of hydroxyls distributed within the test chamber produced by the Boss™ system was consistent with that found in nature, which effectively decomposes a vast number of organic and inorganic compounds as well as kill bacteria, viruses, and mold. 


After extensive testing of the Titan 4000, LRRI detected no measurement of hydroxyls at all, and concluded that if the Titan was producing any hydroxyls, they were too few to be measured. This research confirms the observations of contractors in the field who are unable to remove odors from surfaces and contents with this product. It is very important for the restoration industry and insurance professionals to understand the significant differences in these technologies.

Jay Murphy full Story Odorox® vs Titan


As you know, our PDN Op’s Team members are huge fans of using hydroxyl, and in particular your XL3 units, for any number of applications where odor elimination is required. Many years ago (when the use of hydroxyl gas was still new) we fell victims to the “you get what you pay for” syndrome. Not knowing much about hydroxyl, we thought any machine that said “hydroxyl” was the same, so we bought 4 Titan 4000 Hydroxyl generators. Our first use of the Titan units was at a factory fire where large numbers of bolts of fabric were contaminated with odor from a fire (no visible soot or char). We spoke to the adjuster about placing the bolts of fabric into a room and let hydroxyl run to eliminate the odor. The adjuster was not in favor of us charging for this type of application – he referred to it as “voodoo-science” and didn’t want to pay our daily rate. To this objection we made him a deal, if we couldn’t get the odor out, we wouldn’t charge him anything.

We proceeded to create a “containment room” and placed the bolts of fabric on racks (to allow hydroxyl to flow over and around the individual bolts). After 24 hours, there was little to no change in the odor appearing to come from the bolts, so we left the units run for another 24 hours. Again, little to no change. We didn’t get to charge for the use of the Titians as the adjuster ended up total-loss’ing the entire inventory of fabric. Our next job was a large furniture store/warehouse which had a small fire with lots of soot and odor throughout both the showroom and warehouse. We used your trailer mounted Odorox® hydroxyl units to “pump” hydroxyl throughout the building. It was that job where we started to understand what hydroxyl is and how it should be used.

From that experience, we purchased a few Odorox® XL3’s and placed them on a fire project at a University. Odor from the fire traveled inside numerous adjacent buildings in the immediate vicinity of the building which had the fire. Because there were so many rooms, we needed more XL3’s than we had and needed to “rent” several from Odorox®. The XL3’s worked like a charm! It was at that point that we became believers that hydroxyl and XL3’s were the perfect combination.

As we became more and more comfortable with what the XL3’s were capable of, we began to “look outside the box” at other ways of utilizing the XL3’s as a tool and not just a machine to produce hydroxyl. We were called to a large school fire which had a fire in the gymnasium and left a heavy odor throughout the 285K building – in ceiling systems, behind locker banks, and anywhere air could go, the odor was strong. When we (school staff, our Op’s team, the adjuster, and consultants) first entered the building, there was such a strong odor that people were complaining that they couldn’t stay long (mostly school staff). We explained that we would place hydroxyl units throughout the immediate area to help eliminate the odor. The first question the consultant asked is “what is hydroxyl and what is it going to cost?” Obviously we explained what hydroxyl is and why we felt it was the right product for the odor – they reluctantly agreed. When everyone returned the next day (to the same location in the building) the odor was all but eliminated (one of the staff commented “this smells great” and referred to our XL3’ as “magic machines”). It was at that point that the consultant became a believer!

Throughout that school fire, we used the XL’3, and in fact, you’ll recall that we purchased 30 more units to up or inventory to 60 units. One of the most difficult areas to eliminate the odor was behind the locker banks throughout all of the halls. Lockers have numerous “ventilation holes” inside the lockers and vents in the door. This abundance of ventilation is needed to help air-out the items people store in lockers. This amount of ventilation also allowed the odor to get behind the locker units themselves. Removing locker banks is difficult, time consuming, and expensive, so we had to get creative and come up with an alternate solution – that’s where the XL3’s came into play. We developed a way to “tent” each bank of lockers and pump hydroxyl into the area (lockers) inside the tented area – we ran the XL’3 units for 72 hours. When completed, there was no odor detectible! We then developed ways to pump hydroxyl over, small and hard to reach, ceiling cavities (to eliminate having to remove plaster ceilings).

These unique uses of hydroxyl was made possible because of the design of the XL3’s and the use of an air mover to “pump” hydroxyl over an area. I believe this equipment is a “game changer” in the restoration industry – it is for us! Needless to say, we have no problems charging for and collection (a reasonable value) for the use of hydroxyl these days…..
