Conclusion
MedicCleanAir^® Mobile HEPA Units reduce contamination with at least 75% over all, and between 90 and 100% in the isolation rooms. The MedicCleanAir^® Mobile HEPA Units were put – as per manufacturer’s instructions – at level 2.

Report University Hospital Bonn Germany – Hematology Department: effect of MedicCleanAir^® Mobile HEPA Units on contamination within the patient rooms

This organization wanted to know if the MedicCleanAir^® Mobile HEPA Units could constantly maintain the level of ZERO CFU/m³ for a long period of time, even when windows are often opened in the patient room.

The following documents can be obtained at the office:

• 3 a) DGKH Germany 2007 Hygiene bei immunsuprimierten Patienten – presentation by Dr. A. Simon: page 3: MedicCleanAir^® table with results
• 3 b) DGKH Germany 2005 – summary study Uni Bonn Germany – Dr. A. Simon

Conclusion
The University Hospital of Bonn came to the conclusion that they require 2 MedicCleanAir^® Mobile HEPA Units when they want to bring the level of contamination down to zero (ZERO CFU/M3) in a (cancer) patient’s room, EVEN WITH OPEN WINDOWS. Units were operating at level 2, although the Units have the capability of giving more then double the capacity at level 4.

Conclusion
MedicCleanAir^® Mobile HEPA Units reduce the contamination with minimum 75% to 100% as from a few minutes, continuously day in day out.

This organization has tested MedicCleanAir^®

Mobile HEPA Units and have come to the following conclusion:

MedicCleanAir^® Mobile HEPA Units are able to reduce the contamination of a room with size 3 x 5 x 3 meters height within maximum 30 minutes.

Drawing



Conclusion
The measuring device of the organization was only able to measure the reduction of the contamination by the MedicCleanAir^® units every 30 minutes. As from the first measuring point, contamination was already brought down to practically ZERO. Time lap in between the MedicCleanAir^® devices are able to reduce contamination is therefore between 0 and 30 minutes.

Institut Pasteur was asked by the University Hospital St. Pierre Brussels for testing several purification units (MedicCleanAir^® installed the units in 30 isolation rooms for infectious patients / Tuberculosis)

This Pasteur-organization is THE organization in France in relation to trustworthy testing of Mobile HEPA Units for medical facilities.
MedicCleanAir^® Mobile HEPA Units are able to reduce the contamination of a room with size 3.46 x 4.70 x 2.70 height meters within 7 minutes when put at level 2. Level 2 was the level that we recommended as manufacturer.

Conclusion
MedicCleanAir^® Mobile HEPA Units are able to reduce the contamination within 7.

Notre Dame des Bruyères – Operating Theatres

This test was done on particles as well as on Colony Forming Units/Bacteria

MedicCleanAir^® first installed 2 units in the O.T. and afterwards 1 ISO unit to create positive pressure. The hospital did not change any other settings of existing ventilation, HVAC or air conditioning devices (although we requested to clean these thoroughly)

Results with MedicCleanAir^® Units
Particle counts reduced from 8.297.495/m³ to 112.190/m³ (99% reduction)
CFU counts reduced from 31 CFU to 0 CFU (100% efficiency result)
The operating theatre was (without any other additional measures or changes other then MedicCleanAir^®) re-classified to ISO 7.

Shahid-Rajai Cardiovascular Medical Center, Iran, University of Medical Sciences: operating theatre

This test to particle readings in one of the operating theatres. There were 4 professors involved, including the Dean of the Surgery Center. There was only 1 MedicCleanAir^® Unit installed in the operating theatre and the readings were taken after only 10 minutes. Although this operating time is too short to take readings, the results are clear:

Results with MedicCleanAir^® Units
Average reduction of 80% over all sizes of particles: 0.3 – 0.5 – 0.7 – 1.0 – 2.0 – 5.0 µm

The MedicCleanAir^® Unit was placed in the ICU next to the operating theatre. The ICU is equipped with an existing Air Conditioning unit, taking air from outside the building and blowing it into the ICU without significant pré-filtration. (no integrated HVAC).

Results with MedicCleanAir^® Units
Reductions because of MedicCleanAir^®:
Everywhere to ZERO CFU (0) except on their instruments.

The MedicCleanAir^® Unit was placed in Operating Theatre nr. 2. – only one unit although MedicCleanAir^® advises always 2 units inside operating theatres.
The laminar flow system showed to contaminate the operating theatre severely. Although requested, no additional cleaning was performed, no change it normal ventilation settings.

Results with MedicCleanAir® Units
Reduction between 60 to 80% for particles of 0.5 micron to 5 micron – Classification of the Operating Theatre with MedicCleanAir® Units: ISO 6
