Gaseous removal efficiency
Fast reduction of odor and gaseous pollutants is best achieved by SmokeStop™ filters. Blueair
SmokeStop™ filters are particle filters enhanced with active carbon.
Background
The exposure to gaseous pollutants has increased with the usage of chemical-based household
and personal cleaners, indoor pesticides and aerosol. Also plastics, binders and glues in synthetic
building materials, carpets and furnishing are off gassing. The irritating gases may be factors in a host
of illness, from respiratory disease to chemical sensitivity. Odor causes negative effects as well as
unpleasant feelings. Strong odor has also shown to have significant negative effect on asthma.
Standards and certifications
Shanghai Institute of Measurement and Testing Technology tests air purifiers’ removal rate of formal-
dehyde and VOCs in accordance with GB/T 18801-2001 and GB/T 18883-2002.
Kitasato Research Center of Environmental Sciences (Japan) tests air purifiers’ filtration efficiency of
malodorous substances. Tests for tobacco smoke was tested in accordance with the standard JEM
1467.
Testing and results
Test results from both mentioned laboratories prove the very high efficiency of Blueair units
using SmokeStop™ filters in reducing gases and odors.
VOC filtration efficiency
In 2009, the Shanghai Institute of Measurement and Testing Technology tested Blueair 503 fitted
with SmokeStop™ filter in removing VOC.
Nature attenuates refers to the natural reduction of VOC in the air without an air purifer present.
Testings were conducted in a 30 m
3
(1060 cu. ft.) room with a temperature of 19-21 ̊ C (66-68 ̊ F)
and humidity of 45-55% RH. Initial concentration of VOC was 4.2 mg/m
3
(148 mg/ft

).. The unit was
tested on full speed.
