SEOUL,South Korea (May 5,2025) – New research underscores the importance of hygiene practices in public restrooms,pointing to potential contamination risks from flushing toilets.
Toilet Plume and Airborne Particles
A recent study conducted in collaboration with Kookmin University examined the spread of airborne particles, or “toilet plume,” generated during flushing. The research, focusing on the pollution characteristics of this plume, aims to provide practical hygiene solutions for public facilities.
According to Kim Hyung-jin, a professor of biotechnology at Kookmin University, flushing with the toilet lid open can propel particles up to 92 centimeters (approximately 3 feet) into the air. These particles can remain airborne for about a minute, settling on nearby surfaces such as toilet paper dispensers and walls.
“If these particles come in contact with microorganisms or viruses in the air, special attention is needed for hygiene management,” Kim said.
Open Toilet Paper Dispensers Pose Risk
The study specifically addressed the risks associated with open-bottom toilet paper containers commonly found in public restrooms. Researchers noted that exposing toilet paper to the open habitat increases the likelihood of contamination.
Even when the toilet lid is closed during flushing, partial contamination of the toilet seat and surrounding areas can still occur. The researchers recommend wiping down surfaces with a seat cleaner before use.
Recommendations for Improved Hygiene
As an alternative to open dispensers, the study suggests using sealed containers that minimize toilet paper exposure. These enclosed systems reduce the surface area vulnerable to contamination from flushing.
Reconsidering Public Restroom Hygiene
An official from the Yuhan-Kimberly Seocho Research Institute stated that the study provides an chance to re-evaluate hygiene management practices in public restrooms.

key Takeaways on Public Restroom Hygiene
This Q&A article provides insights into a study highlighting the importance of hygiene practices in public restrooms, particularly concerning the spread of contaminants during toilet flushing. The study, conducted in Korea, emphasizes the risks associated with “toilet plume” and exposed toilet paper.
What is “Toilet Plume,” and How Does it Spread?
The term “toilet plume” refers to the airborne particles generated during flushing in public restrooms. This plume can contain various microorganisms and viruses that can spread throughout the restroom area.
How Far Can toilet Plume Travel?
According to Kim Hyung-jin, a professor of biotechnology at Kookmin University, flushing with the toilet lid open can propel particles up to 92 centimeters (approximately 3 feet) into the air. These risky particles can remain airborne for approximately one minute.
Why is Flushing with the Lid Open Risky?
Flushing a toilet with the lid open can significantly increase the spread of airborne particles, which can deposit on nearby surfaces. This increases the risk of contamination as microorganisms and viruses can spread and settle on surfaces like toilet paper dispensers and walls.
What Are the Risks of Open Toilet Paper Dispensers?
The study specifically addressed the risks associated with open-bottom toilet paper containers. Exposing toilet paper to the open habitat increases the likelihood of contamination from toilet plume and other airborne particles. Since it’s not fully protected, particles will fall and contaminate the paper.
What Recommendations Did the Study Make for Improved Hygiene?
The study highly recommends using sealed toilet paper containers. These closed systems minimize toilet paper exposure and reduce the surface area vulnerable to contamination from flushing. This offers a proactive approach to minimizing contamination in public restrooms.
How Can You Improve Your Hygiene When Using a Public Restroom?
Even with the lid closed while flushing, some contamination of the toilet seat and surrounding areas can still occur. Here are some general tips for improving hygiene and reducing exposure to airborne particles:
- Flush with the lid closed: This is the simplest way to reduce the spread of toilet plume.
- Wipe down surfaces: wipe down the toilet seat and surrounding areas with a seat cleaner before use.
- Handwashing: Always wash hands thoroughly with soap and water after using the restroom.
Summary of Key Findings and Recommendations
Here’s a summary of critical aspects of the research on public restroom hygiene and the recommendations:
| Area of Concern | Finding | Recommendation |
|---|---|---|
| Toilet Plume | Particles can travel up to 3 feet and remain airborne for about a minute. | Flush with the lid closed to minimize spread. |
| Open Toilet Paper dispensers | Increase likelihood of toilet paper contamination. | Use sealed toilet paper containers. |
| General Hygiene Practices | Partial contamination is possible even with the lid closed . | Wipe down surfaces with a seat cleaner before use. |
