and removes 99.97% of airborne particles as small as 0.1 micron. Testings at Kitasato Research
Center of Environmental Sciences of the Blueair 650E has shown that the unit actually reduces
the air from bacteria and viruses with 99% in only ten minutes.
The Blueair filters contain polypropylene, a hydrophobic material that prevents bacteria, viruses
and mold growth.
“How often should I change the filter in my Blueair unit?”11.
In order to maintain the high performance standard you expect from Blueair, it is recommended
that the filter be replaced every six months or sooner if the unit operates in a particularly dirty
environment. The amount of indoor air pollution can vary dramatically from environment to envi-
ronment. Without regular filter replacement, the air cleaner is operating at only a small percentage
of optimum performance.
Many air purifiers have longer periods of recommended filter change. But in time they will clog and
restrict the airflow which in turn lowers the CADR.
“How can I get the most from my Blueair air purifier?”12.
Blueair air purifiers are easy to use. Begin by selecting the right size unit that corresponds to the
room size. The filter should be replaced at the recommended 6-month intervals. Every air purifica-
tion system has limits to the volume of air it can clean, so it is important to follow these common
sense guidelines:
Close windows•
An air conditioner is not expected to work efficiently on a hot summer day with windows
open, as hot air would come in and cool air would go out the window. The same logic ap-
plies here even though contaminated air coming in and clean air going out the window isn’t
visible.
Close doors•
Just as the customer might expect to seal off part of their house when it’s cool outside to
keep their heater working more efficiently, they should seal off the room in which the system
is working for best results. This is especially important for people using a Blueair system to
ease nighttime asthma or allergy attacks.
Operate the system 24 hours a day•
Blueair systems are designed for phenomenally low power usage, so the system can be run
24 hours a day, seven days a week without an increase in electricity consumption. It costs
approximately the same to power one Blueair unit as it does to power a single light bulb
depending on the unit and the operating speed.
Vacuum “fluff”•
If visible “fluff” builds up on the outside of the air intake and outtake grids, it is simply vacuumed
away or wiped clean with a cloth. The air take grid is designed in part to intercept very large
