ISO Class 5 results from Italy

In December 2019, environmental monitoring of Operio took place in the Hospital of Bolzano in Italy that demonstrated the effective area with the device on is ISO Class 5 compliant.

A particle counter was used for measuring the particulate count when Operio was turned off compared to turned on. The test demonstrated that both 0.3 and 0.5 μm particles fulfils ISO Class 5 with concentrations of 0 particles/m3 within two minutes after switching on the device.

How efficient are Toul’s air flow devices to prevent COVID-19?

Toul Meditech have been working for several years with clean air solutions using HEPA filtration which pay an important role in preventing air borne contamination. We have had many questions lately about the protection and safety with the use of our products in respect to Corona.

Toul’s products Operio and SteriStay uses HEPA filtration of class 14 which has an efficiency of at least 99.995 % to filter particulates of sizes less than 0,18 µm. Operio and SteriStay has an air velocity of 400 m3/h and a MPPS (Most Penetrating Particle Size) of 0,145 µm at that speed. See the graph below:


The graph shows that viruses of a size of 0,05-0,15 µm will be captured in the filter efficiently including the Corona virus (SARS-CoV-2) which is approximately 0.1 um in size. As long as the device is running, the number of airborne pathogens in a contained space will be continually reduced with each circulation of room air through the HEPA filter.

When used in conjunction with other anti-contamination practices, and operated as instructed in the user manuals, the Operio and SteriStay are recommended as a tool for healthcare and other facilities to minimize the spread of the Corona virus and other airborne contaminants between 0.5-0.15 um in size.

Statistics over infections from the Orthopedic clinic in Drammen Hospital in Norway show that the infection rate for 645 knee surgeries was 0.3% and 0% for 646 patients with hip surgery. The infection rate prior to the use of Operio and SteriStay was approx. 1.5%.

SteriStay has been cleared in the US

Toul Meditech recently got clearance from FDA to market the instrument table in the USA.

This opens up the market even further on the North American continent. SteriStay has been used successfully in Europe for several years as a standalone instrument table that protects the sterile instruments with HEPA filtered air. When both Operio and SteriStay is combined optimal effects can be reached in the fight against airborne contamination.

Published study on Operio in Neurosurgery

The study at Karolinska University Hospital involving Operio and SteriStay has recently been published in the Journal of Hospital Infection.

Read more

During the study a total of 233 samples were collected during 45 neurosurgical procedures. The use of MLAF units (Operio and SteriStay) significantly reduced the numbers of CFU in the surgical site area (P<0.001) and above the instrument table (P<0.001).

The name of the study is "Effect of mobile laminar airflow units on airborne bacterial contamination during neurosurgical procedures". To read about the result go to the following link: Journal of Hospital Infection.
