The Novaerus Defend 400 is a portable, recirculating air cleaning system designed for continuous 24/7 use in healthcare and other high-risk environments. This FDA-cleared Class II Medical Device is engineered to inactivate airborne pathogens and purify indoor air, making it an essential tool in settings where infection control is critical.

At the heart of the Defend 400 is WellAir’s patented NanoStrike™ technology, which provides a multi-stage inactivation process. NanoStrike technology works by rapidly inactivating airborne microorganisms at the DNA level, preventing them from causing infection. The NanoStrike coils create a powerful burst that perforates pathogen cell walls, leading to their destruction through a combination of osmotic pressure and electroporation by electromagnetic fields. This process ensures that the pathogens are no longer viable, offering reliable protection against a wide range of airborne threats.

The Defend 400 combines NanoStrike technology with a triple-stage filtration system from Camfil®. This system includes a pre-filter for capturing large particles, a HEPA H13 filter for trapping bacterial debris and fine particles as small as 0.12 microns, and a carbon/molecular filter for neutralizing volatile organic compounds (VOCs), gases, and odors. Together, these components create a comprehensive air disinfection and purification process that is both effective and efficient.

Designed for use in medium to small-sized rooms, the Defend 400 is ideal for environments such as operating rooms, outpatient surgery centers, ICUs, dental practices, and other areas where the risk of airborne infection is high. With its portable, plug-and-play design, the Defend 400 can be easily moved to different locations as needed, providing consistent and reliable air quality wherever it is deployed.

This device represents a key line of defense against airborne pathogens, ensuring safer indoor environments for both patients and healthcare providers.
