Why isn’t “COVID-19 Isolation Space” listed as an application for the AIIR Watch Purifier?

The reason that “COVID-19 Isolation Space” is an application listed on the Negative Pressure Machine product page but not the Purifier product page is because isolation spaces use Negative Pressure. 

Using the purifier improves the air quality inside the space but without the negative pressure aspect there is nothing increasing the isolation capabilities of that space. 

The most effective isolation spaces, like Airborne Infection Isolation Rooms in hospitals, use negative pressure to ensure the air inside the isolation space does not escape.
