1. All reported specification values are nominal. 2. The sensible effectiveness is at a maximum flow rate of 21 CFM when the product is used in conjunction with an Inline Filter Box that is installed indoors. 3. The power measurement represents the minimum controllable level of an operating unit and excludes legacy variants that do not have dedicated fan controllers. The nominal power that is consumed by a unit can reach or exceed 16 W depending on the specific combination of supply and exhaust fans. 4. The recommended indoor conditions for the operation of the units are as per the winter and summer comfort zones that are prescribed in ANSI/ASHRAE Standard 55 – 2010. 5. Current MINI units feature four ports which can all be fully ducted whereas legacy units may have only two ports.
In terms of ASHRAE Standard 52.2, G2 is approximately rated to MERV4 whereas G4 corresponds to the MERV7 filtration level. In accordance with EN 779 and ISO 16890, G4 filters can capture 60%-85% of particles that are within 0.3 to 10 microns whereas G2 filters can trap the same size of particles at an efficiency of 30%-50%. On the other hand, our HEPA filters, which are based on EN 1822, can trap at least 99.5% of most penetrating particle sizes that are below 2.5 microns. * *
