Review of BoiE Ozone Generators
Researchers at Fujita Health University confirmed that ozone gas in concentrations of 0.05 to 0.10 parts per
million (ppm), sterilized SARS-CoV-2 (technical name of the coronavirus which causes the COVID-19 disease), during
experiments using an ozone generator in a sealed chamber over 10 hours with 90 percent effectiveness. Efficacy
increased with higher humidity. The EPA safe limit for ozone in occupied areas is 0.05, while the OSHA limit is
0.10 ppm for 8 hours.
The Fujita Health University study reviewed by Dr. Takayuki Murata was the first published test confirming that ozone gas kills the novel coronavirus strain. The results suggest that ozone could be more effective against COVID-19 than it was against previous coronavirus strains. Experiments during the SARS pandemic showed that a minimum of 1 ppm was effective against the SARS strain, an ozone concentration 10 times higher.
“Transmission of the novel coronavirus may be reduced by continuous, low-concentration ozone treatment, even in environments where people are present, using this kind of system,” said Murata. “We found it to be particularly effective in high-humidity conditions.”
Fujita Health University Hospital in Japan has installed ozone generators to reduce infection in waiting areas and patient rooms.
The U.S. Army has reviewed the effectiveness of using ozone to fight the spread of COVID-19 within buildings and vehicles and has released guidelines for ozone generator use.¹ Below are the key conclusions from the U.S. Army Public Health Center:
"Considering the structure of SARS-CoV-2 (COVID-19), and how like viruses respond to ozone exposure, it is estimated that as little as 1 ppm concentration for a matter of seconds is sufficient to achieve as much as 4 logs disinfection." ²
When used with proper protocols, an ozone generator is a proven disinfectant that safely kills both airborne
viruses and those on hard and soft surfaces. Ozone reacts to contamination thousands of times faster than bleach
and leaves no harmful chlorinated by-products. Concentrated ozone can safely decontaminate an entire room, a vehicle,
shoes, clothing, air and surfaces, so long as people, pets and plants are not present during the ozone treatment
and adequate time is allowed to pass before reoccupying a treated area.
Motel rooms and cruise ship cabins are prime examples of spaces that are often cleaned with ozone when the rooms are turned over. People then return and use the sterilized room. An ozone generator can also be used to decontaminate delivered packages outdoors by covering them with plastic and adding ozone to the enclosure. Large garment bags make great ozone enclosures that can hold work clothing, shoes and masks as they are disinfected by ozone that concentrates inside the bag without having to use a washing machine or chemical sprays.
The Environmental Protection Agency (EPA) states that concentrated ozone can be used to disinfect vacant spaces. "High concentrations of ozone in air, when people are not present, are sometimes used to help decontaminate an unoccupied space from certain chemical or biological contaminants or odors." ³ The EPA further states that high concentrations of ozone in air may be appropriate if conditions are controlled to prevent exposure to humans and pets.
No, and here's why. Millions of air purifiers are sold in the U.S. each year. What air purifier manufacturers
won't tell you is that most viruses simply pass straight through. A virus is very small (.004 to 0.1 microns).
Air purifiers are limited to 0.3 microns or larger using high-quality HEPA filters, which is effective for trapping
larger particles such as dust and allergens, but too large to trap something as small as a coronavirus.
Air purifiers are also passive devices that can only act on air passing through, while much of the contamination that causes odors or sickness is present on surfaces the air purifier can never reach. On the other hand, ozone spreads and saturates the air along with fabric and carpets, breaking down volatile organic compounds (VOCs), mold, bacteria, viruses and biological contaminants.4 In the world of chemistry, ozone is a scavenger molecule, a search-and-destroy substance that removes or de-activates impurities and unwanted reaction products.
A virus has no defense against ozone, which had a 99.22% kill rate during the 2003 SARS coronavirus pandemic.5 Ozone has proven, wide-reaching sanitizing applications for homes and businesses. In laboratory experiments conducted by Kowalski et al, an ozone generator removed 99.99% of bacteria within 40-60 seconds of exposure to air ozonation.6 For serious odor elimination and virus disinfection of a large area in a short period of time, ozone generators far surpass air purifiers.
Ozone generators oxidize contaminants in the air, removing strong odors from chemicals, mold, smoke and decay.
The oxidation process breaks down and removes the contamination rather than masking the odor. Unlike chemicals
that leave a residue, an ozone generator leaves nothing behind. Environments that are treatable with ozone include
homes, basements, crawl spaces, hotel rooms, apartments, offices, gyms, sports equipment, fitness centers, locker
rooms, vehicles, boats and much more. Ozone generators can deodorize individual items by simply enclosing or tenting
them in plastic, then connecting the ozone generator to the enclosure. An ozone generator can disinfect viruses
and bacteria from any space then can be left unoccupied during the treatment.
BoiE ozone generators are essential tools for flood and fire restoration, mold remediation, crime scene clean up, sanitizing trash dumpster rooms, and to sterilize bacteria, viruses and mold spores at sensitive places including daycare centers, schools and medical centers. Ozone can also be used to clean and disinfect odors from clothing and foot wear, a process called ozone dry washing. Hunters use ozone generators outdoors to alter their scent in order to stay hidden from wildlife. Water ozonators sanitize and purify drinking water in minutes. For examples of ozone generators that treat a variety of situations, read BoiE's ozone generator treatment guide on this website. You can buy the best ozone generator for every type of use from BoiE.
Advertisers often market low ozone-producing air purifiers as powerful ozone generators. However, these devices
generate roughly 0.05 parts per million (ppm) of ozone, which is too little ozone to reduce contaminants. Rather
they mask odors temporarily with ozone's pungent scent. In EPA laboratory tests, 5-10 ppm of ozone was needed to
kill resistant mold species in low and high humidity environments respectively,7 an amount 100-200 times
higher. Few ozone generators will ever reach the level of ozone needed to perform useful cleaning and disinfection.
You need a BoiE shock ozone generator for that.
Ozone generators that produce high levels of concentrated ozone can effectively oxidize VOCs, mold and other contaminants in unoccupied areas. That is why professional restoration service companies use ozone generators to reduce mold levels and bacteria during mold remediation and water clean-up projects. Most commercial fruit and vegetable crops are cleaned and disinfected of bacteria using ozone because it is the most effective method of killing germs on surfaces. The FDA approved ozone for food use in 2001. While ozone generators are highly-effective at disinfecting and deodorizing, beware of devices that produce a small or unspecified amount of ozone as they don't compare to BoiE ozone generators.
A shock ozone generator can kill mold in the air and on surfaces. However, it takes approximately 1,000 milligrams
of ozone per hour (mg/hr) to kill airborne mold spores and surface mold in a typical 100 sq. ft. room. Since the
ozone starts to dissipate in minutes, ozone will not concentrate enough to kill mold in a space that is too large
for the ozone generator's output, no matter how long that machine runs. That is why it is important to understand
ozone generator output before buying one. When you look at an ozone generator, the first question should be how
many milligrams of ozone does it generate per hour, and is that enough output for the largest space you may need
to treat? The greater the ozone output, the less time the ozone generator will need to run to complete an effective
Low-power ozone generators leave an ozone scent in a large space, but they won't kill mold. The same musty odors will return within hours. Some ozone generator manufacturers attempt to mislead consumers into believing that under-powered ozone generators can remove mold from an entire house with a small or unspecified amount of ozone and rely on the consumer's trust and lack of understanding to sell their products. An ozone generator that produces too little ozone for a particular space will plateau before reaching a high enough ozone concentration to clean and disinfect.
Any responsible person who observes precautions and follows the manufacturer directions can safely perform an
ozone treatment of an unoccupied space. A shock ozone treatment refers to an enclosed area that has reached a high
enough level of ozone exposure to perform a useful amount of cleaning and air purification. In testing conducted
by the EPA's National Risk Management Research Laboratory, an ozone concentration of 10 parts per million was needed
to kill toxic mold specimens in a low-humidity environment.
The ozone treatment may take anywhere from a few minutes to over an hour depending on the size of the space and the power of the ozone generator. People, pets and plants must not be present when an ozone treatment is performed. After the ozone treatment, the air recovery time can take anywhere from 30 minutes to several hours depending on the air temperature and amount of ventilation. The warmer the air the faster the recovery. BoiE has published an ozone generator treatment guide that outlines how an ozone treatment can be performed in a variety of situations and which BoiE ozone generators are recommended for each type of job.
