Innovation in Air Disinfection
The Defend 400 is an FDA-cleared medical device that inactivates aerosolized viruses, bacteria, and fungi, and purifies the air of particulate matter (PM), volatile organic compounds (VOCs), gases, and odours. The device is designed for airborne infection control in small to medium-sized rooms where the risk of infection is elevated. The Defend 400 device combines NanoStrike™ Technology with a triple-stage filtration system from Camfil® to deliver healthy indoor air.
The Defend 400 is UL 2998 and CARB validated for zero ozone and UL 867 safety certified.
NanoStrike™ Technology rapidly inactivates airborne contaminants to help ensure they are no longer a threat of infection.
Medical-grade filters capture debris, small particles, VOCs, gases & odours.
Antimicrobial paintwork reduces the need for regular cleaning.
No emissions and no harmful by-products from our medical-grade components.
Defend 400
The Defend 400 (NV 400) uses WellAir's patented NanoStrike™ technology, combined with a triple-stage Camfil® filter system, to provide a powerful solution for air disinfection and particle removal.
The Defend 400 is a free-standing, portable recirculating air cleaning system designed for continuous 24/7 protection in healthcare or other commercial settings to provide airborne infection control.
The FDA has cleared the Defend 400 as a Class II Medical Device to filter out and inactivate airborne viruses and bacteria for medical purposes within medium to large rooms and indoor spaces.
The Defend 400 inactivates aerosolized viruses, bacteria, and fungi and purifies the air of pollen, particulate matter (PM), volatile organic compounds (VOCs), and odours. Proven to reduce and inactivate:
Our Technology
Novaerus Technology Explained
Used in the Defend 400, NanoStrike has been independently tested and proven effective at inactivating the smallest of airborne viruses, bacteria, mould spores, and pollen. Watch our videos to learn more about NanoStrike Technology, the Defend 400 and our TRUE HEPA filtration.
Help Reduce the Threats Associated with Dirty, Sick and Toxic Air
Indoor air can be up to five times more polluted than outside air – teeming with viruses, bacteria, fungal spores, volatile organic compounds, particulate and allergens. Exposure to these pollutants can lead to many virus-based illnesses, bacterial infections, asthma, allergies and a host of long-term health issues.
This is why the Defend 400 was designed to clean the air via a four-stage air disinfection and purification process, inactivating and reducing a wide range of pollutants and pathogens.
The Defend 400
Independently Tested and Proven
The Defend 400 achieved a net LOG reduction of MS2 bacteriophage virus, a surrogate for SARS-CoV-2 after 45 minutes of 5.31 which is equivalent to a net percent reduction of 99.9995%.
Why Indoor Air Matters
Humans spend between 80–95% of their lives inside inhaling more than 10 m3 of indoor air every day.
Pollutants and pathogens suspended in that air can be absorbed into our throats, eyes, lungs and bloodstream, negatively impacting our health, wellbeing, cognition, and performance.
