TREATMENT SPACE

The ActivePure® Medical Guardian, model F170A is a device intended for medical purposes that is used in professional healthcare environments. The device

is designed to treat a space approximately 3,000 cubic feet that would have 8' to 10' ceilings. Recommended mode of action is to operate the device on the

highest speed possible continuously. The device recirculates ambient air continuously through the device where the filter using straining and attraction reduces

airborne contaminants from the air. Hydroxyl radicals and super ions created by the photo catalyst ActivePure® are mixed with the contaminant reduced air

which then enters the treatment space. The ActivePure® photo catalyst reduces the viability of microorganisms 4-6 log such as Staphylococcus epidermidis and

MS2 as tested, shown in Table 3. Larger spaces or operating on lower fan speeds may require multiple devices. Operational guidelines are provided to users in

the form of an Owner's Manual. The length of time required to reach optimal reduction varies as a function of space volume and the dynamics of what occurs

within the treatment space including:

• Degree of contaminants in the air or being introduce by activities in the space

• Movement of people or equipment within the space

• Rates of ventilation

The device is intended to result in a 4-6 log reduction of airborne microorganisms from initial concentrations in 60 minutes as shown in Table 1. The ActivePure®

Medical Guardian, model F170A is not a sterile device and is not intended to create a sterile environment.

The information on the device CFM performance and air exchanges for the different speed settings is shown in Table 2, to illustrate the influence of treatment

space to air exchanges on different fan speeds. These are provided to assist in determining the number of devices or fan speed settings necessary for a given space.
