Wood’s air puriers
Poor air quality -
a health hazard.
Using your Wood’s
air purier
Wood’s proudly present ELFI, the all new, Swedish made, air purier series! Together with Swedish experts with more than
40 years experience, Wood’s has developed truly unique air puriers with very high purications level and very low noise
levels and energy consumption. The lter technique used in Wood’s air puriers has a Swedish patent and is used where
the demands of powerful and ecient air purication are very high, without compromising with energy consumption
or noise levels. Our customers can be found in a vast variety of businesses and walks of life; from the food industry and
healthcare to private households and small business owners. In short, our costumers are everybody who takes their health
seriously! Our extensive experience of research and manufacturing results in patented air-cleaning products with maxi-
mum purication levels and minimal maintenance, sound level and expenses.
Wood’s air puriers clean the air with a light electrical charge. This means that Wood’s doesn’t have to use dense lters to
catch particles and air pollution. Therefore, Wood’s air puriers are very low on power consumption and noise level, as no
large and noisy fans are needed to circulate the air in the room.
Wood’s air puriers are made in Sweden and have a 99,98% purication level. Wood’s air puriers are of top quality and
capacity and are delivered with a 10 years warranty plan. Read more about our warranty plan in the Warranty chapter.
Air purier doesn’t start.
• Check that it is connected to power
source and that it is switched on.
• Check that the top latch is rmly closed
• Check the fuse on the back of the air
purier.
No air ow from the purier
• Check that the air ow isn’t blocked.
• Move the puriers away from any
surrounding surfaces.
Noises coming from the air purier
• Check that the air purier isn’t in contact
with any surrounding surfaces.
Wood’s air puriers are very easy to use. Place the air purier on a level ground in the middle of the room. Plug it in to an
earthed power source and choose preferred fan speed. The Wood’s ELFI 900 lets you choose between four fan speeds; a
higher fan speed means higher air ow and faster purication but also slightly higher power consumption and noise level.
• When the air purier is running, the green light on the front of the machine is lit.
• When the light ashes in red, a lter change is due. Read more about changing the lter in the Filter chapter.
• For best results, place the air purier in the centre of the room. Make sure that the air ow isn’t blocked as this will
reduce the machine’s capacity.

Technical data Wood’s ELFI 900 Trouble shooting:
Workings of your
Wood’s air purier
The Wood’s ELFI 900 circulates the air through the room with a small fan. It is usually recommended that the air purier
is powerful enough to circulate the air through the room twice every hour for best air purication. The unit is therefore
recommended for rooms up to 160m2, depending on the environment. In a demanding environment, for example very
dirty rooms or rooms in where people smoke, you need to circulate the air more often. The maximum working area might
therefore be smaller than in a less demanding environment.
When the air is circulated in the room and passed through the ionization part of the air purier the particles in the air are
charged with a positive charge. The particles in the air now have a positive charge, which makes them stick together. This
increases their size and makes them more easily caught.
The Active Ion HEPA lters are placed in the next coming part of the purier. The Active Ion HEPA lters are ionized and
the electrical charge of the lter media attracts and catches the charged particles. This technique allows low density of the
lter media and a very high level of purication at low energy consumption and noise level. By using an electrical charge to
separate the particles from the air, Wood’s doesn’t have to rely on the density of the lter to receive a high level of puri-
cation. This means that no noisy and energy consuming fans are needed to circulate the air, which is needed in puriers
using traditional lter of the same capacity.
Carbon lters:
It also possible to equip the Wood’s ELFI 900 with carbon lters to rid the air from unpleasant gases and odours from
tobacco smoke, wood burning, garages, garbage rooms etc. This combined method of air purication guarantees the
cleanest, healthiest and most pleasant indoor environment. The carbon lters are custom made to t the Wood’s ELFI 900
and are placed directly outside of the Active Ion HEPA lters. This ensures the longest operating life of the carbon lters as
all particles are caught in the particle lters before the air pass through the carbon lters, ridding the air from gases and
odours.

Daily, we inhale larger amounts of harmful particles in our homes. Wood’s air puriers remove 99,98% of all pollen, dust,
sot, exhaust fumes, bacteria and mould spores from the indoor air and provide an instant relief for people suering from
allergies and asthma. People who aren’t sick are also aected by air pollution and will notice the dierent when the air is
kept free from particles and pollution using a Wood’s air purier. Wood’s air puriers also remove radioactive radon daugh-
ters from the indoor air and prevent diseases from spreading in the workplace or in your home.
High amounts of particles and pollution is unfortunately a common problem in most cities and inhaling these pollution can
impair the lung capacity of children and even lead to serious diseases for adults. The problem increases when the outside
air is dry during the winter. An air purier from Wood’s guarantees a healthy indoor environment, no matter where you use
it and you can improve the air quality before it aects your health.
