ScentLok Technologies’ OZ500 neutralizes organic odor in outdoor gear and can clear the air inside RVs. 

Picture this: It’s spring, and the time has come to open the RV for the season. You unlock the door, step inside and — whoof! — the smell of mildew, food and pets knocks you on your keister. What to do?

The first step is to eliminate the root cause of the odor. Excessive moisture leads to mildew, and even though you might resolve the water issue, the odors can linger, requiring advanced procedures to neutralize any offensive smells that can lead to unpleasant surroundings and even health issues. One way to tackle the problem is to use an ozone generator.

ScentLok Technologies specializes in making odor-neutralizing clothing and devices for outdoor enthusiasts. Organic odors in clothing that are undetectable by humans can be smelled by animals and scare them off. This is especially important when hunting or photographing wildlife. The company developed its OZ500 ozone generator to be used with a special bag to “deodorize” clothing before adventuring outdoors. The same system can be employed in a larger space, such as an RV, without the bag.

The OZ500 consists of a housing with a switch panel and backlit LCD display on the front, and an ozone blower port on the side, which can be hooked up to a hose to direct the flow. The control panel has two arrows and a power button to activate the device and set the run time. The system includes an AC power cord, along with a 12-volt DC plug for use in a vehicle or an RV.

To test the system, we used it in an 8-by-15-foot room that contains a cat-litter box, and in a 33-foot trailer that, through aging and use, has developed odors of its own. In both cases the OZ500 was effective, destroying organic odors and leaving a fresh, clean-smelling space.

The back of the unit has screw mounts for hanging on a wall near a power source.

It’s important to note that high concentrations of ozone can be hazardous, and some people can be sensitive to even small quantities. Because of that, ozone generators must be used in unoccupied spaces, and those spaces must be fully ventilated before they are reoccupied. Ozone generators should also be used with caution in the presence of rubber and elastics, which can be damaged by exposure.

We operated the OZ500 for five minutes in the room with the kitty litter and achieved an ozone concentration of between 90 and 150 mcg/m3. This is a relatively low level but still may be irritating to some people with acute sensitivities to ozone. Running the unit for a longer period in the enclosed space will result in higher concentrations, which are more effective at killing the odor-causing pathogens. Note that ozone generators may not be legal in all jurisdictions. Be sure to check local and state laws before purchasing.
