1.The particle removal test was conducted by KCL(Korea Conformity Laboratories)
The testing environmental conditions are followed by the Korea Air Cleaning Association standard (SPS-KACA 002-132:2018) that is complied with the indoor air purifier test evaluation.
1) Test method and process
(1) Measurement of the particle background concentration in a test chamber
- This test should be maintained that particle concentration in the test chamber is not more than 3X10⁵ unit/㎥ by applying the procedure of A.3 of Annex A to the Korea Air Cleaning Association standard.
(2) Measurement of particle attenuation rate
- The particle in the chamber should be generated until its concentration reaches 10³ ~10⁵ unit/㎥ while operating an air stirring fan.
Measure the natural attenuation and attenuation by the air purifier at a single test. Measure the natural attenuation for 40 minutes and then operate the air purifier until it drops to 99.99%.
- As the particle removal test was conducted in an enclosed test chamber with a size of 30㎥ for the duration of 40 minutes, the performance may vary in the actual living environment of customers.
