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 95-100% purication level. Wood’s air puriers are of top quality and
capacity and are delivered with a 10 years warranty plan.
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.
Daily, we inhale larger amounts of harmful particles in our homes. Wood’s air puriers remove 95-100% 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.
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 400 lets you choose between two 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 Filter chapter.
• For best capacity, 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 400 Trouble shooting:
Workings of your
Wood’s air purier
The Wood’s ELFI 400 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 80m2.
When the air is circulated in the room and passed through the ionization part of the air purier they 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 ionized lter media is places in the next coming part of the purier. 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 purication. 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 400 with a carbon lters to rid the air from unpleasant gases and odours from to-
bacco smoke, wood burning, garages, garbage rooms etc. This combined method of air purication guarantees the clean-
est, healthiest and most pleasant indoor environment. The carbon lters are custom made to t the Wood’s ELFI 400 and
are placed directly outside of the particle 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.
