Manual Cleaning vs. Far-UVC

In our quest for cleaner, healthier spaces, manual cleaning has always been a cornerstone of hygiene. Yet, even the most diligent efforts can leave behind invisible threats—bacteria, viruses, and other pathogens that linger on surfaces, waiting to spread. What if there were a way to add an extra layer of protection to these efforts?

The solution is Far-UVC: a disinfection technology that works hand-in-hand with traditional cleaning methods to elevate hygiene standards. This blog explores how combining manual cleaning with Far-UVC can help create safer, healthier environments.

Far-UVC and Manual Cleaning: A Perfect Partnership

Rather than viewing manual cleaning and Far-UVC as competing solutions, they can complement each other, forming a comprehensive cleaning protocol. Manual cleaning addresses visible dirt and grime, while Far-UVC targets microscopic threats that might be missed.

For example, manual cleaning can be used to remove physical dirt and grime, providing an initial layer of cleanliness. Then, Far-UVC light can be used to ensure continuous microbial sanitation throughout the day, especially in areas that experience high levels of traffic and touch. This approach maximizes both cleanliness and sanitary safety.

The Strengths and Weaknesses of Each Method

Pros of Manual Cleaning

1. Proven Effectiveness

   Traditional methods—dusting, mopping, and scrubbing—remove visible dirt and grime while killing most bacteria and viruses using disinfectants, reducing the risk of disease spread. 

2. Versatility

   Manual cleaning can be applied to many surfaces—carpets, upholstery, tiles, metal, and more. It reaches areas that might be challenging for automated systems, through good old-fashioned elbow grease.

3. Immediate Visual Results

   A visibly clean space reassures residents, employees, and customers, creating an immediate sense of comfort and satisfaction.

Cons of Manual Cleaning

1. Microbial Buildup Between Cleaning Sessions

   High-touch surfaces can quickly become contaminated after cleaning, posing ongoing risks of disease spread. 

2. Labor-intensiveness

   Manual cleaning is time-consuming and physically demanding, requiring significant resources for large spaces.

3. Potential Health Risks

   Many cleaning agents pose risks to human health and the environment, and improper handling can damage sensitive equipment.

4. Human Error

   Thorough cleaning depends on the diligence of the individual, which means some areas may be missed or improperly sanitized.

Pros of Far-UVC

1. Antimicrobial Efficiency and Human Safety

   Far-UVC light effectively deactivates bacteria, viruses, and other microorganisms without harming human skin or eyes, making it ideal for continuous disinfection in occupied spaces.

2. Chemical and Mercury-Free

   Far-UVC offers a hygienic, chemical-free method for microbial sanitation, potentially reducing the need for harmful cleaning agents. Additionally, Far-UVC devices are mercury-free, aligning with the European Union's commitment to restricting hazardous substances and promoting environmental sustainability. 

3. Automation

   Far-UVC systems can operate automatically, ensuring consistent sanitation without requiring manual intervention. 

4. Sustainability

   Far-UVC is highly energy-efficient, delivering exceptional disinfection results with low operating costs. For example, a study demonstrated that far-UVC lamps achieved 184 equivalent air exchanges per hour(eACH), surpassing other methods of indoor disinfection.

Cons of Far-UVC

1. Not a Replacement for Manual Cleaning 

   Far-UVC cannot mechanically remove dirt, dust, or debris—it deactivates microorganisms and thereby increases hygiene levels. 

2. Limitations on Range and Obstruction

   Far-UVC works best on exposed surfaces and may struggle to disinfect shadowed or hidden areas

Conclusion

Creating safer, cleaner spaces does not mean choosing between old and new methods. By combining manual cleaning to remove physical debris with Far-UVC technology to neutralize microbes continuously, this synergistic approach ensures a comprehensive standard of hygiene.
