Wood’s air purifiers
Poor air quality -
a health hazard.
Using your Wood’s
air purifier
Wood’s proudly present ELFI, the all new, Swedish made, air purifier series! Together with Swedish experts with more than
40 years experience, Wood’s has developed truly unique air purifiers with very high purifications level and very low noise
levels and energy consumption. The filter technique used in Wood’s air purifiers has a Swedish patent and is used where
the demands of powerful and efficient air purification 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 purification levels and minimal maintenance, sound level and expenses.
Wood’s air purifiers clean the air with a light electrical charge. This means that Wood’s doesn’t have to use dense filters to
catch particles and air pollution. Therefore, Wood’s air purifiers 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 purifiers are made in Sweden and have a 95-100% purification level. Wood’s air purifiers are of top quality and
capacity and are delivered with a 10 years warranty plan.
Air purifier doesn’t start.
• Check that it is connected to power
source and that it is switched on.
• Check that the top latch is firmly closed
• Check the fuse on the back of the air
purifier.
No air flow from the purifier
• Check that the air flow isn’t blocked.
• Move the purifiers away from any
surrounding surfaces.
Noises coming from the air purifier
• Check that the air purifier isn’t in contact
with any surrounding surfaces.
Daily, we inhale larger amounts of harmful particles in our homes. Wood’s air purifiers 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 suffering from
allergies and asthma. People who aren’t sick are also affected by air pollution and will notice the different when the air is
kept free from particles and pollution using a Wood’s air purifier. Wood’s air purifiers 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 purifier from Wood’s guarantees a healthy indoor environment, no matter where you use
it and you can improve the air quality before it affects your health.
Wood’s air purifiers are very easy to use. Place the air purifier 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 flow and faster purification but also slightly higher power consumption and noise level.
• When the air purifier is running, the green light on the front of the machine is lit.
• When the light flashes in red, a filter change is due.
• Read more about changing the filter in Filter chapter.
• For best capacity, place the air purifier in the centre of the room. Make sure that the air flow isn’t blocked as this will
reduce the machine’s capacity.

Workings of your
Wood’s air purifier
The Wood’s ELFI 400 circulates the air through the room with a small fan. It is usually recommended that the air purifier
is powerful enough to circulate the air through the room twice every hour for best air purification. The unit is therefore
recommended for rooms up to 80m

.
When the air is circulated in the room and passed through the ionization part of the air purifier 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 filter media is places in the next coming part of the purifier. The electrical charge of the filter media attracts
and catches the charged particles. This technique allows low density of the filter media and a very high level of purification
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 filter to receive a high level of purification. This means that no noisy and energy
consuming fans are needed to circulate the air, which is needed in purifiers using traditional filter of the same capacity.
Carbon filters:
It also possible to equip the Wood’s ELFI 400 with a carbon filters to rid the air from unpleasant gases and odours from to-
bacco smoke, wood burning, garages, garbage rooms etc. This combined method of air purification guarantees the clean-
est, healthiest and most pleasant indoor environment. The carbon filters are custom made to fit the Wood’s ELFI 400 and
are placed directly outside of the particle filters. This ensures the longest operating life of the carbon filters as all particles
are caught in the particle filters before the air pass through the carbon filters, ridding the air from gases and odours.
