Henry Schein recently announced an exclusive agreement with Radic8 to distribute the UK-based manufacturer’s air purifier systems in the U.S. and Canada.
The Radic8 Viruskiller is being marketed under the U.S. Food and Drug Administration (FDA) enforcement policy for air purifiers during the COVID-19 public health emergency, according to a press release. It is “intended to be effective at killing SARS-CoV-2 based on its demonstrated effectiveness against viruses that are similar to SARS-CoV-2 or are harder to kill.” The Radic8 air purifier has not been tested against SARS-CoV-2, but has been tested against harder to kill viruses, such as the adenovirus.
The systems show a 99.9999%, 6 log reduction, kill rate in a single air pass. The kill rate is used to describe what percentage of a given germ is killed by a particular process or disinfectant. Single air pass kill rates are critical to minimize the risk of cross contamination. Air purification systems can help improve indoor infection control, reducing the risk of exposure to certain pathogens.
When using technology to reduce airborne and droplet virus exposure, the key is controlling the airflow to take the danger away from the breathing zone and purifying the air as it passes through the unit in a single air pass. Controlled airflow drags contaminated air away from the breathing zone, replacing it with purified air. That air is released from the top, pushing contaminated air to the floor. The fan drags it back toward the unit that creates laminar airflow.
The Radic8 air purifier is available in three different versions:
The Radic8 Viruskiller 401 (VK 401) is designed for medium to large rooms. It is suited for spaces up to 645 square feet. The purified air is released against both sides of the wall to maximize distribution and create controlled airflow within the space. Its air exchange capacity makes it best for dental operatories, waiting rooms and sterilization rooms.
The Radic8 Viruskiller 103 draws contaminated air away from the breathing zone in the patient waiting area up to 1,076 square feet. It creates controlled airflow within the space and can be used to regulate positive pressure for medical and health care facilities. Its air exchange capacity makes it well suited for large dental waiting rooms and large open operatories.
The Radic8 Hextio is a compact air purifier for spaces up to 215 square feet. The Hextio has an optional directional airflow hood and a quiet night mode. The light indicators show when the air is purified. The desktop unit is well suited for reception desks and small offices.
