01
Starting from one section
Installation starts in the highest-risk room, usually a single operating theatre or an isolation room. Further rooms are connected later without intervention in the completed part.
For your role
Benefits for the facility and a documentable hygiene regime
Information for the director, the finance department, nursing management and the hygiene department: documentable benefits of implementation, the scope of investment and the relationship to the hygiene plan.
Benefits
Three key facts you need to know about the MEDIfogg® system
−95%
airborne microbial load
Lower airborne load in the rooms where patients are most vulnerable. The staff who work there for an entire shift share the same environment.
20 min
room preparation
No moving of equipment, no covering of surfaces and no waiting for ventilation. The cycle is started by a single member of staff.
Record
of every cycle
From the Professional level, every cycle has a record with the time, room and operator identification. It is created without any action by staff.
Capacity
Predictable time for room preparation
In practice, room disinfection is often carried out whenever operations allow. A permanently installed system turns it into a scheduled item with a fixed duration.
01
Fixed cycle duration
20 minutes from start until the room can be used. The duration is set during design for the given room and is the same every time it runs, so it can be factored into the operating theatre schedule.
02
No staff tied up
The cycle needs no supervision. Staff carry on with their work while it runs.
03
No moving of equipment
Equipment stays in place and in operation. The most time-consuming part of preparation is no longer needed.
Documentation
Evidence during inspections
An inspection assesses not only whether a hygiene plan exists, but also how compliance with it is documented.

Inspection and accreditation
An automatic record of every cycle means the evidence is created without any action by staff and does not depend on how much time they have.
02
Complaint or suspicion
When asked which cycles ran in a specific room on a specific day, the answer is available in the system history. At the Enterprise level, the archive is kept with no time limit.
Evidence
Clinically demonstrated efficacy
Efficacy was measured on a ward of a Slovak university hospital over six months. The results were peer reviewed and published in the scientific journal Antibiotics.
Demonstrated results: A reduction in airborne microbial load of 95% with daily application and of 71.3% with application twice a week after 180 days, statistically significant (p < 0.001). In the treated rooms, the load on surfaces also fell (p = 0.010); compared with the control rooms, the difference on surfaces did not reach statistical significance. Measured on an open ward in full operation, not in a laboratory chamber.
Hygiene regime
Relationship to the hygiene plan
MEDIfogg® complements existing hygiene and infection control measures with an automated step of clinically demonstrated efficacy. The hygiene plan remains in force; manual disinfection and existing protocols remain unchanged.
- Changes to the hygiene plan
- The system is added as a further step; existing procedures do not change.
- Position of the authorities
- In the public consultation on the new decree of the Ministry of Health of the Slovak Republic on the equipment of inpatient healthcare facilities (LP/2026/442), seven institutions supported the position that the germicidal (UV) lamp should not be the only permitted technology. They include the Public Health Authority of the Slovak Republic, the Health Care Surveillance Authority (ÚDZS), the State Institute for Drug Control, the National Institute of Children's Diseases (NÚDCH) and the Association of Hospitals of Slovakia. ÚDZS, NÚDCH and KOZ SR explicitly supported whole-room dry fog disinfection.
- Product registration
- Stabilised hydrogen peroxide 7.7% with ionised silver (Ag⁺). After the cycle, the peroxide breaks down into water and oxygen. Silver is present in the product only in trace amounts, below 0.02%, so no harmful or visible residues remain in the room. Biocidal product of product type 2 under the European Biocidal Products Regulation (EU) 528/2012.
- Certificates and patents
- • TSÚ Piešťany certificate of conformity No. 26TSU0002 under the Machinery Directive 2006/42/EC and the Electromagnetic Compatibility Directive 2014/30/EU, valid until January 2029
• TSÚ test reports on machinery safety, electrical safety (EN 60204-1) and electromagnetic compatibility
• Product efficacy verified according to European standards: bacteria (EN 1276, EN 13697), yeasts and moulds (EN 1657, EN 13624), enveloped viruses (EN 14476, EN 16777), Legionella (EN 13623), C. difficile spores (EN 13704), fogging application (NF T 72-190)
• Two European patents granted by the European Patent Office in Munich after substantive examination, covering the whole system and the hydraulic nozzle (EP 4678294 and EP 4678293). Patent protection in 28 countries, registered trademarks in 33 countries.
• For every installation, the official test, certificate and expert opinions from TSÚ Piešťany on the designated technical equipment, plus an inspection report
Legislation
Institutions' comments on the draft decree
In the public consultation on the draft decree of the Ministry of Health of the Slovak Republic on minimum requirements for the material and technical equipment of inpatient healthcare facilities (LP/2026/442), seven bodies proposed that the germicidal (UV) lamp should not be the only permissible technology for disinfecting air and surfaces. These are comments on a draft; the decree in this wording is not yet in force.
| Institution | Type of comment | What it proposed |
|---|---|---|
| Association of Hospitals of Slovakia (ANS) | ordinary | In addition to germicidal lamps, allow other technologies for the decontamination of air and surfaces (it cited ozone generators as an example); it rejected technological exclusivity. |
| Federation of Employers' Associations of the Slovak Republic (AZZZ SR) | fundamental | Permit other, more effective technologies instead of the exclusive use of germicidal lamps; do not hinder new technologies. |
| Confederation of Trade Unions of the Slovak Republic (KOZ SR) | fundamental | Throughout the text, add device-based decontamination by aerosol fogging with whole-room coverage alongside the germicidal lamp. |
| Public Health Authority of the Slovak Republic (ÚVZ SR) | ordinary | Replace the term “germicidal lamp” with the wording “germicidal lamp or other alternative technology for the disinfection of air and surfaces” and align the provisions with the decree on outpatient care. |
| National Institute of Children's Diseases (NÚDCH) | ordinary | It supported device-based decontamination by aerosol fogging with whole-room coverage; it highlighted dry fog, the short application time, effectiveness both in the air and on surfaces, and material compatibility. |
| Health Care Surveillance Authority (ÚDZS) | fundamental | It supported whole-room aerosol disinfection with dry fog and a technology-neutral solution. |
| State Institute for Drug Control (ŠÚKL) | ordinary | Add the option of using another device with the same purpose and the same or greater effect; it pointed out the limited effectiveness of germicidal lamps in practice and the impact of radiation on equipment. |
Investment
Scope of investment by department
The system is installed room by room and department by department. The decision therefore concerns a specific department, not the budget for the whole building.
02
How pricing works
The price is made up of the central unit, the number of sections and the number of nozzles. One central unit serves an entire operating suite or department, and each theatre or room is a separate section with its own nozzles. Adding another theatre therefore does not mean a new investment in the whole system, only the addition of a section.
03
Financing and procurement
The system can be purchased or leased; for larger projects we can also arrange financing through partners. We discuss how it is classified (medical technology or construction investment) and the procurement procedure with your finance department.
