BlueAir 250E Digital HEPA Silent Air Purifier
The new Blueair 250E in-room air purifier is the only air purifier with its room
capacity to use HEPASilent™ technology, a combination of the best features
of electrostatic and mechanical filter technology that allows delivery of more
clean air, at a faster rate, with less noise.
Digital Display Function
The 250E comes with an easy to use remote control and digital display system
that gives the user instant feeback of particle detection, air purifier speed
and timer operation.
The 250E is among the highest energy efficient and quietest operating air
purifiers in its class, with a room capacity of 165 sq. ft (11 x 15 ft room).
Blueair is the system for people living with allergies, asthma, or other respiratory
conditions, or for anyone who wants cleaner, more breathable air.
A revolutionary combination of advanced filter media and an encapsulated ion
particle charging chamber makes it possible for the Blueair air purification
system to achieve better results than either mechanical or electrostatic technology
alone. Our nontoxic polypropylene filter contains millions of ultra- thin fibers
that trap tiny particles as they pass through the pleats. One of the least
harmful plastics for human health and the environment, polypropylene works
without outgassing or shedding irritating microscopic fibers into the air.
It eliminates bacteria, viruses and mold naturally, without chemical additives
also captures more dirt than competitive systems. And as used filters are discarded
and decompose, the filter media converts into harmless carbon dioxide and water.
Particles a HEPA filter alone might miss are captured with an electrostatic
charge. HEPASilent™ technology moves particles through an enclosed ion
chamber, which attaches a charge to the particle itself. Charged particles
cling more easily to the filter media, resulting in higher filter efficiency
overall. Because most electrostatic air cleaners charge the filter media itself,
the charge dissipates over time and renders the filter less efficient. By constantly
charging incoming particles, instead of the filter, HEPASilent™ technology
keeps on working effectively and reliably.
*Standard HEPA filters measure efficiency at 0.3 microns. A typical HEPA filter
removes 99.97% of particles of the 0.3 micron size. HEPASilent technology removes
99.97% of particles at 0.1 micron on it`s lowest speed.
