Think about all the places your shoes go in a single day. From public restrooms to busy sidewalks, your shoes come into contact with all sorts of things, some of which you’d probably rather not think about. Shoes, unfortunately, can be carriers of all kinds of germs and pathogens, and that’s why footwear hygiene is becoming increasingly important.
Infection prevention and control (ICP) is a growing concern for both public and private spaces. Hospitals, schools, food processing plants, and even homes are looking for ways to minimize the spread of illness, and one area that’s getting more attention is the cleanliness of our shoes.
That’s where the shoe disinfectant machine comes in. These devices are designed to sanitize footwear, reducing the risk of tracking unwanted germs into clean environments. There are several different types of shoe disinfectant technologies available, including UV-C light, ozone, and fogging systems.
This article explores the world of shoe disinfectant machines. We’ll take a look at the different types of technologies used, discuss their effectiveness, and help you understand whether a shoe disinfectant machine is right for your needs.
How UV-C and Ozone Shoe Sanitization Technology Works
Shoe disinfectant machines often use ultraviolet C (UV-C) light and ozone to kill germs. Let’s take a closer look at how these technologies work.
UV-C Light Disinfection
UV-C light works by messing with the DNA and RNA of microorganisms. DNA and RNA are like the instruction manuals for how living things grow and thrive. When UV-C light scrambles these instructions, the microorganisms can’t reproduce or cause infections.
UV-C light is most effective at certain wavelengths. Different pathogens respond differently to various wavelengths of UV-C light. Reputable shoe disinfectant machines will be designed to emit the most effective wavelengths for the pathogens they’re designed to kill.
Ozone Disinfection
Ozone (O3) disinfection works through oxidation. Ozone molecules are unstable, and they react with microorganisms by stealing their electrons. This process damages the cell walls of the microorganisms, causing them to break apart and die.
UV-C and ozone can work together to disinfect even better than they do on their own. The UV-C light weakens the cell walls of the microorganisms, making them more vulnerable to the oxidizing effects of the ozone.
What are the Advantages of UV-C and Ozone Shoe Sanitizers?
Broad-Spectrum Efficacy
UV-C and ozone sanitizers are effective against a wide range of pathogens, including viruses, bacteria, and fungi. In a time when concerns about hygiene are high, it’s reassuring to know that these machines have been proven to kill common pathogens such as:
- MRSA (Methicillin-resistant Staphylococcus aureus)
- C. diff (Clostridioides difficile)
- E. coli (Escherichia coli)
- Norovirus
- Coronavirus
Non-Chemical and Environmentally Friendly
Unlike traditional chemical disinfectants, UV-C and ozone sanitizers don’t leave behind harmful residues. They’re also less likely to contribute to antimicrobial resistance, which is a growing concern in healthcare settings.
The active ingredient, ozone, is naturally derived. It’s created when oxygen molecules (O2) are exposed to UV-C light or an electrical discharge. For these reasons, UV-C and ozone disinfection is a good choice for people who are concerned about the environment and want to reduce their exposure to toxic chemicals.
Ease of Integration and Maintenance
UV-C and ozone shoe disinfectant machines are easy to integrate into existing facility management protocols. They don’t require special training or equipment to operate, and they can be easily incorporated into existing cleaning schedules.
These machines also have minimal maintenance requirements. The UV-C lamps will need to be replaced periodically, but this is a simple and straightforward task. Ozone generators may also require occasional cleaning or maintenance, but this is typically a quick and easy process.
UVZone® Shoe Sanitizer: A Case Study
Let’s take a closer look at the UVZone® Shoe Sanitizer as an example of how this technology works.
Technology and Features
The UVZone® Shoe Sanitizer uses ultraviolet (UV) light to kill microorganisms on shoes. UV light damages the DNA and RNA of bacteria, viruses, and fungi, preventing them from reproducing and causing infections. The UVZone® unit passes shoes through a chamber where they’re blasted with this germ-killing light.
UVZone® partnered with Corning® HPFS® to develop its technology. Corning® HPFS® makes high-quality glass that lets UV light pass through it easily. This glass is used in the UVZone® unit to make sure the UV light can reach all parts of the shoes.
Performance and Validation
The UVZone® Shoe Sanitizer has been tested in a number of labs and real-world settings. Testing shows that it can reduce microorganisms by up to 99.9993 percent. These tests were done by NSF International, Microchem Laboratory, CREM Co. Labs, and the University of Minnesota.
Here are some examples of how UVZone® has been used in healthcare:
- Norton Audubon Hospital
- AdventHealth Connerton
- Gaylord Specialty Healthcare
Facilities like these have used UVZone® to reduce healthcare-associated infections (HAIs).
Practical Application and Maintenance
UVZone® stations are typically placed at the entrances of facilities. People simply step onto the platform, and the unit automatically starts a disinfection cycle. These cycles can be set for 6, 8, or 10 seconds, depending on the level of disinfection needed.
Maintaining the UVZone® unit is pretty simple. Regular maintenance includes:
- Wiping down the unit to keep it clean.
- Replacing the UV bulbs once a year to ensure they’re working properly.
Shoe Fogging Sanitizer and Deodorizer Machines
You may have seen shoe disinfectant machines at gyms or even in people’s homes. They use a fogging method to sanitize and deodorize shoes, and here’s what you should know about them:
Technology and Features
These machines use fog, rather than a spray or liquid, because a fog can reach all areas inside the shoe, even the toe box. The key ingredients in the fog are typically thymol and silver ions, which are known for their dual-action when it comes to eliminating bacteria, fungi, and odors.
The fogging solution is formulated to be gentle on shoe materials, so you can use it on leather, suede, canvas, and other common shoe materials without causing damage.
Applications and Benefits
You can find these machines in a wide range of locations. Many people use them at home, but they’re also becoming popular in gyms, locker rooms, and shoe stores. Athletes like them, and so do people in healthcare settings.
The fogging solution is designed to be corrosion-free, so it’s safe to use on shoes with metal components, like cleats or eyelets. You can also use the fogging cleaning solution on helmets, hospital footwear, and other gear that’s prone to bacterial growth.
Hospital-Grade Sterilization
Some machines have the ability to provide hospital-grade sterilization. They integrate fog disinfection, sterilization, deodorization, and hot air drying into one process.
These machines can be especially helpful for shoe rental businesses, like bowling alleys or ice rinks. Using a shoe disinfectant machine helps maintain hygiene and extends the lifespan of rental shoes.
