Disclaimers
(1.) Energy- saving fully automatic functions Auto mode: if the air purifier detects pollutants in the air, it adapts the fan speed to the room air quality and filters up to 5.9 m³/h - for an ideal room climate! Eco Mode: If the Mighty detects no pollution in the room air for 30 minutes, the fan stops to save energy. It starts again as soon as the air deteriorates again. Filter replacement indicator: The filter replacement indicator shows when the carbon filter or HEPA filter needs to be replaced - so you don't have to keep an eye on your filter.
(2.) 99.9% of viruses, bacteria, fungi and pollen could be proven to be cleaned from the air by the Coway air purifier with the GreenHEPA filter applied, according to tests by Japan Food Research Laboratories (JFRL) under the JEM 1467 standard
(3.) Tested with Influenza A virus (H1N1) and Staphylococcus aureus on Coways GreenHEPA filter medium by Japan Food Research Laboratories (JFRL). After 24 hours of testing at room temperature, no growth of the material could be detected.
(4.) The CADR (Clean Air Delivery Rate) of particles is tested according to GB/T18801-2015 by a certified third party laboratory.
- The measurement specifications are defined in GB/T 18801-2015, which requires two particle concentration decay rates to be determined within a test chamber of defined volume (Vchamber): a natural decay rate with the air filter inactive (knat) and a decay rate obtained when measured in a 30th ㎥ test chamber is performed. This test chamber is empty except for the air filter placed on a table. Two fans mix and circulate the air. In addition, there are also some measuring devices (mainly hoses) in this chamber.
The chamber is maintained at a temperature of 25 (± 2 °C) and a relative humidity of 50 (± 10%).
Cigarette smoke is used as the test aerosol and the number of particles > 0.3 µm is measured using an optical aerosol spectrometer using the indoor air filter (kAC).
The decay rates "k" are determined from the measured decay of the particle concentration C (t) over time, starting from the initial concentration C0:
(5.) Room size is calculated according to the NRCC-54013 standard. The CADR is tested according to GB / T18801-2015.
- NRCC (National Research Council Canada): method for testing air purifiers
- Room Size Formula): Room Size = 0.26 * CADR
Test results may vary based on customer's actual usage environment.
