The need & The Solution

Legionnaires Disease - Introduction to the Risk

Legionnaires Disease - Introduction to the Risk

Safe Shower invented a unique shower head, patent based, that minimizes the risk of Legionnaires' disease from sources of shower heads, By continuous disinfection in the shower head, with a small sized disinfection unit (such as chlorine pill or UVC LED unit).

Legionella is a parasite bacterium, disinfecting the water system does not prevent the spread of legionella in the shower head. In order to prevent the development of the Legionella bacteria we must continue to disinfect the shower head even when water flow stops. In regular shower heads, once the water stands, the chlorine evaporates and air enters the system. 

Legionella, the bacterium that causes Legionnaires’ disease, occurs naturally in freshwater environments, like lakes and streams. Generally, the low amounts of these bacteria in freshwater do not lead to disease. However, Legionella can pose a health risk when it gets into building water systems. To do this, Legionella first has to grow (increase in numbers). Then it has to spread through small water droplets (aerosolization) that people can breathe in. Safe Shower is invented the solution which minimize the risk for Legionnaires’ disease in Hotels, Hospitals and Other establishments from sources of shower heads.

Infrequent use of fixtures can effectively add “dead legs” to a water system. The water leading to an infrequently used faucet or shower head may sit in a pipe at Legionella growth temperature for days or weeks and bacteria growing in the "dead leg" can be shed into the flowing stream. Infrequent use of plumbing fixtures, like in a hotel luxury suite for example, encourages Legionella bacteria to live in biofilms where they can obtain nutrients and be protected from disinfectants.

In order to understand the solution of the legionella problem we must know a little about the microbiology of the bacterium,

The legionella bacteria is very small, almost like a virus and is a parasitic bacterium, these facts mean that it is very difficult to kill the bacteria relative to others microorganisms and if legionella enter to the stagnant water without residual chlorine Like a shower head the bacteria can multiply.


These facts have led me to change the perception in disinfecting endpoints, we must continue to disinfect continuously, at all times. our patent for the solution is by sealing the end point for air entry and then the stagnant water can be easily disinfected, the truth is, this is a very simple solution that I think will save a lot of life and save on high maintenance costs.


I will note that our patent claims include all types of existing disinfection units, all types of faucets and not just shower heads, we were able to innovate a principle, a new concept for disinfecting endpoints.

The need

Hotels are exposed to claims from guests exposed to the disease,

Hospitals and hotels spend tens of thousands of dollars a year to disinfection, which our solution makes better.

In 2011, The Aria Resort & Casino, located on the Las Vegas Strip, told guests who stayed during a two-week period between June 21 and July 4 that they may have been exposed to high levels of disease-causing legionella bacteria.

In 2016, dozens of guests at the hotel in Shfayim were evacuated from their rooms after the pollution was discovered, the hotel was sued for compensation.

In 2017, a resident of the central region of Israel went to the Daniel Hotel for a vacation and died six days later after suffering from the Legionnaires' disease. In his lawsuit for NIS 2 million, his lawyers claim that the hotel failed to test bacteria concentrations in the water system of the Ministry of Health.

According to the CDC, “about 6,100 cases of Legionnaires’ disease were reported in the United States in 2016. However, because Legionnaires’ disease is likely underdiagnosed, this number may underestimate the true incidence.”

About one in 10 people who gets sick from Legionnaires’ disease will die!!!

Dr. Paul Edelstein, a Legionnaires’ disease researcher, has estimated that more than 100,000 cases of Legionnaires’ disease could be occurring each year in the U.S.

The Solution is prevention

Safe Shower solution is a pendent patent with a working prototype chlorine based.

Hospitals and Hotel are required by regulation, to perform a routinely examination to detect Legionella in the bathing water. When bacteria are detected at a concentration higher than the permissible, the institution is required to perform an expensive disinfection process and then make a re-test to verify success of disinfection, this procedure take a lot of man hours and is very costly.

This patent will save a great deal on hotel or hospitals costs, save the maintenance personnel time, save a number of repetitive samples due to less Legionella-positive lab results, save on lawsuits for avoiding accidental Legionella and savings in preventive actions like disinfecting the water system in cases of Legionella positive results. But most importantly, it will save lives.

Safe Shower's showerhead connects to every standard water line as regular shower head like showerheads exist in hospitals, hotels and private homes, by doing so they provide an additional layer of protection, which in turn minimizes the risk of Legionnaire disease from sources of hot and cold-water systems.
