PhoneSoap’s viral TikTok video shows how unsanitary bathroom hand dryers are

Utah-based UV sanitizer company PhoneSoap just went viral for a mind-blowing video about keeping bathroom hand dryers clean.

Driving the news: The company recently posted a video on its TikTok account, asking how “sprouted” hand dryers are. The video has racked up nearly 7 million views.

  • The video shows someone taking samples from various dryers and putting them in a Petri dish to see what bacteria are growing on them after three days.
  • The end of the video reveals the petri dishes covered with different colonies of bacteria, supporting the idea that hand dryers aren’t very hygienic and that in fact “drying your hands is the best option”, as stated the TikToker.

What they say : TikTok users are both horrified and grateful to have witnessed the discovery, with one user saying, “Ohhhh. I wish I hadn’t seen that…I’m glad I did…but oh my god.

  • Another user commented that he always preferred to use paper towels anyway: “…so I can turn off the sink and open the door without touching.”

The science behind it: Researchers from the University of Connecticut and Quinnipiac University conducted a similar experiment in 2018 that unfortunately yielded the same disturbing results.

  • “Petri dishes exposed to bathroom air for two minutes with the hand dryers off grew only one colony of bacteria, if any. However, Petri dishes exposed to air hot from a bathroom hand dryer for 30 seconds produced 254 colonies of bacteria,” Harvard Health reported.
  • Another study published in the Journal of Hospital Infection found that hand dryers contained significantly more germs after scientists spent several months collecting samples from hospital bathrooms in three different cities in Europe.
  • “Cultures of these samples revealed that the total amount of bacteria in the air and on surfaces was consistently much higher in all restrooms when jet dryers were used. The most dramatic differences were seen between surface of the hair dryer itself and the surface of the towel dispenser: in Udine the dryer was covered with 100 times more bacteria, in Paris it was 33 times higher, and in Leeds it was 22 times,” IFL Science reported.

Details: PhoneSoap was founded in 2011 by BYU alumni and cousins ​​Dan Barnes and Wes LaPorte, according to its official website.

  • The company appeared on Shark Tank in 2015 and struck a $300,000 deal with Lori Greiner in exchange for a 10% stake in their company, according to Deseret News.
