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.

Defend 400 | Air Cleaning Device
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 cleaning process, inactivating and reducing a wide range of pollutants and pathogens.
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 & odors
Antimicrobial paintwork reduces the need for regular cleaning
Medical-grade components generate no emissions and no harmful by-products
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.
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%.
The First Line of Protection Against Airborne Viruses and Bacteria
Developed by the WellAir team of scientists and engineers, NanoStrike technology harnesses a range of physical concurrent pathogen inactivation process to safely dis-infect the air. NanoStrike coils provide a powerful strike that works to burst airborne pathogen cells, rapidly inactivating them, ensuring they are no longer a threat of infection.
