Defend 1050 Portable Air Purification

Product Information

The Defend 1050 is a free-standing, portable recirculating air
cleaning system designed for continuous 24/7 front-line protection
in healthcare settings. It is a Class II Medical Device that has
been FDA Cleared. The device utilizes NanoStrikeTM Technology and a
triple-stage medical-grade filter system to filter out and
inactivate airborne viruses and bacteria. In addition to
disinfecting the air, it also removes pollen, particulate matter
(PM), volatile organic compounds (VOCs), and odors. The Defend 1050
is UL 2998 and CARB validated for zero ozone and UL 867 safety
certified.

Product Usage Instructions

Find a suitable location: Choose a large room or indoor space
where you want to improve air quality.
Place the Defend 1050: Position the device in the center of the
room, ensuring that there is enough space around it for proper
airflow.
Connect the power: Plug in the power cord of the Defend 1050 to
a suitable electrical outlet.
Turn on the device: Use the power button to turn on the air
cleaning device.
Select the desired speed: Adjust the speed setting of the
Defend 1050 according to your preference. Higher speeds may be more
effective in larger spaces or areas with higher contamination
levels.
Leave the device running: For optimal results, keep the Defend
1050 operating continuously, 24/7.
Maintenance and filter replacement: Follow the manufacturer’s
instructions for cleaning and replacing filters to ensure the
device continues to function effectively.

Note: The Defend 1050 was tested in a hospital breakroom and
showed a substantial reduction in airborne bacterial bioburden.
While the device is primarily designed for healthcare settings, it
can also be used in other indoor spaces where air quality
improvement is desired.

PRODUCT BACKGROUND

The Defend 1050 is a free-standing, portable recirculating air cleaning system designed for continuous 24/7 front-line protection in healthcare settings to provide airborne infection control where the risk of Healthcare-Associated Infections (HAIs) and Surgical Site Infections (SSIs) are at their highest.

The Defend 1050 (NV 1050) is an FDA Cleared Class II Medical Device that

filters out and inactivates airborne viruses and bacteria for medical purposes

Defend 1050 Air Cleaning Device

within large rooms and indoor spaces. The Defend 1050 uses NanoStrikeTM Technology combined with a triple-stage medical-grade filter system to provide a combined solution for air disinfection and particle removal. It

inactivates aerosolized viruses, bacteria, and fungi and purifies the air of pollen, particulate matter (PM),

volatile organic compounds (VOCs), and odors.

The NV 1050 is UL 2998 and CARB validated for zero ozone and UL 867 safety certified.

OBJECTIVE
To test the hypothesis that the use of a portable stand-alone air cleaner in a staff break-room within a hospital environment is effective in reducing airborne bioburden in the environment.

METHODOLOGY
The levels of airborne bioburden were measured by collecting 100 litre air samples on TSA agar plates using an impaction air sampler.
An equal number of test and control samples were taken on different dates. Samples were taken in duplicate. Test and control samples were collected over 18 days each. 72 air samples (on to agar plates) were collected in total during the study. The air samples were analyzed by EMSL lab for bacterial counts and identification of three most prominent species present in each agar plate.
A Defend 1050 was operated at speed 3 in the environment during test sampling. The air cleaner device was turned off during the control sampling days.

RESULTS
There was an overall colony count reduction of 57.5% between control and test samples (p-value 0.053).
Bacterial species identification results reported a total 6 bacterial pathogen species and 21 bacterial opportunistic pathogen species.
A total of 2,670 colony counts of pathogens and opportunistic pathogen species were obtained in control samples. In contrast, a total of 1,000 colony counts were obtained in test samples. Therefore, in the pathogen and opportunistic pathogen count combined we observed a 63% reduction after the use of the Defend 1050.

CONCLUSIONS AND DISCUSSION
The use of the Defend 1050 portable stand-alone air cleaner in a hospital breakroom has shown substantial reduction in airborne bacterial bioburden overall.
