In today's pursuit of ultimate cleanliness and hygiene, ozone (O₃) technology, thanks to its powerful disinfection capabilities, is increasingly being used in restaurant kitchens, hotel facilities, garbage rooms, and even campus environments. Dubbed the "Swiss knife" of disinfection, it can simultaneously handle multiple tasks, including air purification and water treatment. However, controversy surrounding ozone continues: Is it an "angel" that ensures environmental hygiene, or a "devil" that poses potential health risks?
For every manager who cares about employee health, customer experience, and regulatory compliance, a comprehensive and in-depth understanding of this technology is essential before making a choice.
The benefits of ozone: Why it's so popular as "angel hair pasta"
The reason why ozone is widely used is due to its three incomparable physical properties:
- Powerful broad-spectrum bactericidal effect: Ozone is a powerful oxidant that rapidly destroys bacterial cell membranes, viral protein coats, and fungal structures, even more efficiently than chlorine. It effectively kills everything from E. coli to various influenza viruses, and can also break down odor-causing organic molecules.
- No chemical residue: This is one of ozone's most attractive advantages. After completing its disinfection and sterilization mission, the unstable ozone molecules decompose and revert to harmless oxygen (O₂), without the secondary pollution caused by chemical disinfectants. This property makes it extremely valuable in food processing and drinking water treatment.
- Permeable gas permeability: As a gas, ozone can diffuse into every corner, gap and surface of the space, which is incomparable to traditional liquid wiping and ultraviolet (UV) lamps that require straight-line irradiation, and can achieve true dead-angle disinfection.
On the surface, ozone appears to be the perfect solution to sanitation challenges. However, its powerful capabilities come with risks that should not be ignored.
Ozone Risks: The Devil's Side We Must Be Aware of
Any powerful tool is a double-edged sword, and ozone is no exception. Its disadvantages are as prominent as its advantages:
- Harm to the human respiratory system: This is the core risk of using ozone technology. It's internationally recognized that inhaling high concentrations of ozone can severely irritate and damage the respiratory mucosa, causing coughing, wheezing, and even lung damage. Therefore, all ozone-based air disinfection must be performed in a completely unmanned environment.
- Accelerated material aging and corrosion: Its strong oxidizing properties can not only kill microorganisms, but also corrode equipment, accelerate the aging of rubber seals, plastic products and some metals. Long-term improper use will increase the maintenance cost of the facilities.
- Strict regulations: Due to its potential harmful effects, many regions around the world, including Hong Kong, have strict laws and regulations regarding upper limits for ozone concentrations in public and workplaces. Exceeding these limits not only harms health but also risks violating regulations.
- Instability and secondary contamination: Ozone cannot be stored and must be generated on-site. However, under certain technologies (such as impure ultraviolet lamps), nitrogen in the air may react with oxygen to form nitrogen oxides (NOx), causing secondary pollution.
Common ozone technology and safety regulations
市面上，產生臭氧的技術主要有兩種：電暈放電法（常用於大型臭氧空氣消毒機）和紫外線照射法（特定波段如185nm的UV-C燈管會產生臭氧），常見於光等離子空氣淨化機。此外，臭氧水技術將臭氧溶解於水中，用於物體表面消毒，是一種相對更安全的應用方式。
If your scene really needs to use ozone, be sure to follow the following safety golden rules:
- Absolute isolation: The device can only be started in a closed, unoccupied space.
- Adequate ventilation: After disinfection, you must wait for enough time for the ozone to decompose on its own, and open the windows or start the fresh air system to ventilate thoroughly to ensure that the ozone concentration in the air drops to a safe level before people can enter.
- Professional monitoring: Configuring an ozone concentration monitor is a scientific means to ensure environmental safety before personnel enter.
Seeking a better option: When "human-machine coexistence" becomes a necessity
Ozone's characteristics make it a "terminal," "disposable" disinfection tool, suitable for thorough disinfection of empty kitchens or garbage rooms at the end of each day. However, for spaces that require 24/7 operation and frequent occupancy, such as restrooms, smoking areas, offices, and open restaurant lobbies, ozone is clearly not a viable solution.
The real challenge for managers is:Is there a technology that can provide powerful deodorization and purification capabilities while completely eliminating the safety risks of ozone and achieving absolutely safe "human-machine coexistence"?
The answer is yes. This is exactly where the value of the new generation of air purification technology lies.
PureZone®: Zero ozone, a commercial tool for continuous cleaning
Unlike traditional devices that rely on ozone, the PureZone® Bipolar Ion Air Purifier was designed from the ground up to eliminate the ozone path and is specifically designed to solve persistent air quality issues in challenging environments.
It uses a unique zero ozone emission design, the core of which is non-thermal plasma (NTP) and bipolar ion technology. This technology does not release harmful substances, but actively generates reactive oxygen species (ROS) inside the body, effectively and safely achieving the following:
- Actively decompose odor molecules: It can directly destroy the chemical structure of odor molecules such as ammonia (urine smell) and hydrogen sulfide (rotten eggs smell), decomposing them into simple odorless substances, achieving true "deodorization" rather than the short-term "olfactory masking" of ozone.
- Destroy pathogen structure: Confirmed by a third-party laboratory, this technology can eliminate common pathogens such as E. coli at up to 99%, providing reliable hygiene protection for public spaces.
- Full-effect filtration and purification: PureZone® is more than just a single technology. It incorporates a HEPA filter, simultaneously filtering out five levels of suspended particulate matter. Powered by a professional-grade turbine fan, it actively draws in air from the entire room, achieving a comprehensive "decomposition + filtration" purification process unmatched by traditional ozone generators or simple HEPA purifiers.
Ozone is an effective disinfection technology, but its application scenarios are limited and its safety management requirements are extremely high. For modern commercial spaces that strive for excellent service quality and protect the health of employees, exposing employees and customers to any potential risks is unacceptable.
Rather than choosing between the "angel" and "devil," choose a safer and more efficient path. PureZone®, with its zero-ozone, active decomposition technology, is designed to address this dilemma. It not only completely eliminates the problems of odor and pathogens, but also transforms past complaints about "poor air" into a showcase that demonstrates your unwavering commitment to service quality, employee care, and brand image.
