SUBJECT Test of Naturion Ioniser NA50 for Its Performance of Clean Air Delivery Rate (PM2.5, PM10) CLIENT Serumi International Private Limited 36 Armenian Street #02-02 Singapore 179934 Attn: Mr Sean Gan PY TEST DATE 23 March 2015 DESCRIPTION OF VACCUM CLEANER The photograph and specifications of Naturion Ioniser NA50 were listed in Annex A. METHOD OF TEST The Naturion Ioniser NA50 was tested in a chamber of 200 L (Annex B); Initial particular matter concentrations were adjusted to around 400 µg/m 3 to 450 µg/m 3 for PM2.5 and PM 10; Fan was powered on during ioniser operation; The PM2.5 and PM10 concentrations were monitored under conditions with and without Naturion Ioniser NA50 operation. AHAM AC-1-2013 Method for Measuring Performance of Portable Household Electric Room Air Cleaners was used as a reference (Annex C). Laboratory: TÜV SÜD PSB Pte. Ltd.

RESULTS (Continued) 3. Calculation of Clean Air Delivery Rate (CADR) By referring to AHAM AC-1-2013 Method for Measuring Performance of Portable Household Electric Room Air Cleaners, the Clean Air Delivery Rate (CADR) in terms of PM2.5 and PM10 removal was calculated by: CADR = V chamber (K ioniser K natural decay ) (Annex C) Where V chamber = 200 litres K ioniser = linear regression of Ln (PM2.5/PM10- Naturion Ioniser NA50 Operation) Vs Time K natural decay = linear regression of Ln (PM2.5/PM10- Natural decay) Vs Time The CADR calculation result were listed in Table 3 and Table 4 Table 3 CADR of Naturion Ioniser NA50 in terms of PM 2.5 removal Values V chamber, litres 200 K ioniser, 1/minute (R 2 = 0.97) 0.2744 K natural decay, 1/minute (R 2 = 0.99) 0.0686 CADR (in terms of PM 2.5 removal), litres/minute 41.20 CADR (in terms of PM 2.5 removal), litres/hour 2,470 Table 4 CADR of Naturion Ioniser NA50 in terms of PM 10 removal Values V chamber, litres 200 K ioniser, 1/minute (R 2 = 1.00) 0.3529 K natural decay, 1/minute (R 2 = 0.99) 0.0520 CADR (in terms of PM10 removal), litres/minute 61.08 CADR (in terms of PM10 removal), litres/hour 3,611 Page 4 of 10
DISCUSSION The PM2.5 concentrations decreased from 418 µg/m 3 to 7 µg/m 3 in a 200 litre chamber after 15 minutes operation of Naturion Ioniser NA50 or decreased by 98.3%. The PM10 concentrations decreased from 445 µg/m 3 to 2 µg/m 3 in a 200 litre chamber after 15 minutes operation of Naturion Ioniser NA50 or decreased by 99.6%. The Clean Air Delivery Rate (CADR) of Naturion Ioniser NA50 in terms of PM2.5 removal was calculated to be 41.20 litres/minute or 2,470 litres/hour. The Clean Air Delivery Rate (CADR) of Naturion Ioniser NA50 in terms of PM10 removal was calculated to be 61.08 litres/minute or 3,611 litres/hour. DR.
