Formaldedyde filtration efficiency
In 2009, the Shanghai Insitute of Measurement and Testing Technology conducted tests on Blueair
503 fitted with SmokeStop™ filter in removing formaldhyde from the air.
Nature attenuates refers to the natural reduction of formaldehyde in the air without an air purifer present.
Tests 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 formaldehyde was 1.5 mg/m
3
(53 mg/ft
3
). The unit was
tested on full speed.

Deodorization Performance
In 2010, deodorization performance test was conducted by the Kitasato Research Center of Envi-
ronmental Sciences (Japan). The table shows how long it takes (minutes) to eliminate each tested
substance to 99% if operating the Blueair 650E fitted with SmokeStop™ filter on full speed in an
unventilated room.
