A New Weapon in the Fight Against the Spread of Bacteria in Hospitals

A New Weapon in the Fight Against the Spread of Bacteria in Hospitals

For years scientists have been telling us that germs are launched from our toilets every time we flush.




Scientists at Leeds University tested the air above toilets and found that the germ, C. difficile, which causes violent bacteria and vomiting can be sprayed up to 10 inches above toilet seats with every open flush. These germs were found on the sides of the toilet, on the top, and on the floor.

Their answer to this problem is quite simple but not entirely confidence inspiring–close the lid before you flush.

That’s great advice for the average person, what about our hospitals and other healthcare facilities. There’s got to be a better way to prevent the spread of bacteria like Staphylococcus, C. difficile and E. coli in these high risk environments other than just suggesting patients keep a lid on it.

Part of the solution to reduce the amount of infection could be the installation of vacuum toilets.

Vacuum Toilets Produce No Evidence of Bacterial Contamination from Flush Overspray in Testing Conducted by NSF International completed in October 2012.

NSF International conducted additional custom testing to compare the flush plume or overspray produced by AcornVac’s vacuum toilets with two common types of gravity flush toilets – a 1.28 tank style toilet and a common commercial wall hung toilet with 1.6 GPF flush valve.

Test Results: AcornVac’s vacuum toilets showed no detectable overspray or levels of bacteria on the toilet seat or in the area surrounding the toilet, while the gravity flush toilets had detectable levels of overspray and bacteria on the toilet seat and in the area surrounding the toilets.

Test Area NSF


The cistern flush toilet produced contaminated droplets in zones R and 2. The flush valve toilet had the highest concentration of contaminated droplets in zone R but also produced contaminated droplets in zones 2 and 3.

What should you do? Aside from considering where you store your toothbrush and razor in your home bathroom, we suggest getting more information on vacuum flush toilets.

And if the reduction in germs flying through the air isn’t incentive enough, consider a vacuum flush toilet only uses about a half gallon of water per flush.
