Intensive care units
Help reduce the risk of healthcare acquired infections
Inactivate airborne pathogens in ICUs
ICU and oncology patients are at heightened risk for healthcare-acquired infections (HAIs) due to the severity of their illness. Patients typically have a compromised immune system, long length of hospital stay, several caregivers performing multiple tasks, and a high quantity of invasive devices being used.
All of these factors contribute to a greater potential for contact with biological or environmental contamination.
Viruses
Inactivate airborne viruses before they infect vulnerable patients.
Particles
Remove fine airborne particulate matter.
Bacteria
Inactivate airborne bacteria including superbugs like MRSA, TB, and C.diff.
Air disinfection for healthcare environments
Wherever people are coming and going, pathogens and pollutants are being introduced to the indoor environment. WellAir's portable air disinfection devices and air cleaning systems use our patented NanoStrikeTM Technology to inactivate aerosolized viruses, bacteria, and fungi, 24 hours a day.
Our Defend range of FDA-cleared Class II medical devices combines our powerful NanoStrike Technology with a triple-stage filtration system. These devices not only inactivate pathogens but clear the air of pollutants such as pollen, particulate matter (PM), volatile organic compounds (VOCs), gases, chemicals, and odors.
Healthcare-acquired infections
Why Disinfect the Air
Healthcare-acquired infection (HAI) is a serious and widespread problem with an estimated 1 in 10 patients acquiring an infection during a hospital stay. In American hospitals alone, the Centers for Disease Control (CDC) estimates that HAIs account for an estimated 1.7 million infections and 99,000 associated deaths each year.
Over 30% of healthcare-acquired infections possibly involve airborne transmission at some point.
The Importance of WellAir Air Cleaning and Purification Devices in Intensive Care Units
This peer-reviewed study was published in the Journal of Hospital Infection reports on WellAir Air Cleaning and Purification Devices in an ICU. This first-of-its-kind study highlights the number of microorganisms in the air and evaluates the effectiveness of air purifiers in reducing the rate of nosocomial infections within the ICU.
The Defend 400 Significantly Reduces Airborne Bacteria in an Urgent Care Outpatient Facility
An urgent care outpatient facility located in New Jersey that was running at normal capacity and actively treating patients tested the Defend 400 at one of their three locations in November 2021. Testing was carried out in a breakroom, examination room, nurse station and waiting room.
During the 5 consecutive days, the Defend 400 significantly reduced total bacterial count by 52%, including a 60% reduction in opportunistic pathogens and a 43% reduction in pathogenic bacteria.

When we found out about WellAir and what NanoStrike Technology could do for our dental practice, we added multiple devices to improve our air disinfection protocols. We don’t have to pay for or dispose of replacement filters with the Protect 900 and Protect 200 units. The units have been very quiet, effective and show our patients that we take their safety and the safety of our staff seriously.

After reviewing multiple technologies, I chose the Protect 900 from WellAir. Their NanoStrike technology completely (and I mean completely) destroys airborne viruses, bacteria, mold, and fungi. Two units covered the area we needed. Once they arrived they were easily set up, not requiring any particular installation.
I was thrilled at their compact size and appearance, and especially at how extremely quiet they were to run! This is crucial to their success-- that they actually get used! I also don’t have to worry about buying replacement filters or maintenance costs. Having cleaner air for my staff is critical to workplace safety and I can highly recommend this solution.

In the case of the air samples collected during the period of operation of the system, the number of colony-forming units was up to 96% lower than in the case of air samples collected before the system started to be used for strains of both bacteria and fungi.
The hospital staff found the WellAir air disinfection system to be: tolerable, easy to use, and safe for patients and staff. The WellAir air purification system complements existing measures to combat infections and does not require additional interventions to ensure that it functions without interruption.

Uzsoki Hospital, Hungary
After the initial COVID-19 crisis period had ended, 60 pulmonology workers were screened for SARS-CoV-2 antibodies.
Nationally, 8% of Hungary’s healthcare professionals had been infected; in the Uzsoki COVID-19 department, not a single staff member tested positive for antibodies, an outcome the hospital’s chief COVID-19 nurse attributes in part to continuous air disinfection.

The microbiological tests of the air in the areas where the devices were installed revealed a significant reduction in the number of microorganisms. Moreover, the elimination of unwanted odors in the tested rooms was noted.
The devices tested in our facility deserve to be widely used in healthcare institutions, particularly in sites of high epidemiological risk.

Not a single infection occurred after the installation of the WellAir disinfection devices. WellAir helped to reassure mothers over safety concerns and contributed to increased revenue by differentiating us from other hospitals that don’t offer the technology.
Furthermore, during the periodical test by the Public Health Inspectors for air quality, WellAir exceeded our expectations and we managed to get approval without any problem.

St George’s Hospital, Mumbai, India
We installed and tested WellAir's Air Disinfection Units in St George's Hospital, Mumbai. The devices have been working 24/7 since early May 2020 in COVID-19 ICU wards. The Microbiology Department conducted bio-burden tests in the COVID-19 ICU wards at regular intervals (air settle plates method) for one month and found that the CFU count was always within permissible limits when [the WellAir] devices were working.
The devices are silent and safe for use around patients and effective in improving and maintaining acceptable air quality levels, reducing the chance of transmission of coronavirus, and protecting frontline healthcare workers.

The operation of the devices has clearly improved air quality, significantly decreasing and eliminating the unpleasant smells that were present previously. The noise emitted by the equipment is insignificant, it does not disturb the patients.
The [test] results reveal that apart from reducing the number of organic molecules causing the smells, the equipment also significantly decreased the quantity of pathogenic organisms.
