Dobrich Hospital – Ambulances

Dobrich Hospital Install Airius PureAir Air Purification in their Ambulances

Ambulance Air & Surface Purification

Key Points:
  • Continuous 24/7 protection
  • Purifies both the air & surfaces
  • Neutralises up to 99% bacteria & viruses
  • Provides Protection for Medical Staff & Patients
  • Up to 99.99% effective against COVID19


Dobrich Hospital is a public medical facility in Dobrich city centre, Bulgaria. Following installation of the Airius PureAir system in their Orthopaedic, Surgical and ER departments in 2020 the hospital were eager to explore further high-risk infection areas, including ambulance vehicles.


Ambulances are a common source of contamination for hospitals. In an effort to reduce the risk of infections introduced to the hospital from ambulances, in particular the SARS-CoV-2 virus, Airius worked with Dobrich Hospital to supply an effective vehicular air and surface purification solution.


Dobrich Ambulance PureAir NPBI Air Purification Installation

The Airius NPBITM system from GPS was specified and installed into a pre-contaminated ambulance for testing. Within 20 minutes of the NPBITM system being activated airborne particulate matter had reduced by 98%.

Start of Test
397 μg/m3 – PM1.0
523 μg/m3 – PM2.5
606 μg/m3 – PM10

Air Purification Test Before Installing Airius PureAir NPBI

After 20 Minutes
008 μg/m3 – PM1.0
011 μg/m3 – PM2.5
012 μg/m3 – PM10

Air Purification Test After Installing Airius PureAir NPBI

The hospital was extremely impressed with the results and have since installed the Airius NPBITM system throughout their entire fleet of ambulance vehicles.


“We purposely planted microorganisms in one of our ambulances. We re-examined the contaminated areas after a week of normal operating conditions [with NPBI] and they came out completely sterile.”

Dobrich Hospital Head Manager

What is the PureAir+ NPBI Series

PureAir NPBI Air Purification Fan Shield & Product Banner

The Airius PureAir NPBITM Series is an air and surface purification and airflow circulation fan system, designed to deliver the highest level of pathogen, particle and odour elimination in any type of indoor commercial or community environment.

Featuring the latest in Needlepoint BiPolar Ionisation (NPBITM) technology from one of the world’s leading manufacturers of indoor air quality systems – Global Plasma Solutions, the PureAir+ Series uses the power of ions to provide continuous round-the-clock sterilisation, neutralising up to 99%+ of all known pathogens, VOCs and odours, in both the air and on surfaces

The PureAir NPBITM also provides all the features and benefits of the world’s most popular destratification and airflow circulation fan, balancing temperatures, improving comfort, reducing heating and cooling costs and cutting carbon emissions.

How does it work?

The PureAir NPBITM Series integrated GPS NPBITM system emits a high concentration of positive (+) and negative (-) ions, which are circulated into spaces via the fan

The polarity of the ions attracts them to all particles within the space, causing the particles to cluster together and make them filterable. They also bond with and neutralise pathogens, VOCs and odours by removing them of a hydrogen atom, breaking them down into their basic, harmless and odourless compounds, such as O2, CO2, N2 and H2O.
