3. Using your Wood's air purifier
• Place the air purifier on a level ground in the middle of the room.
• Connect the unit to a grounded power outlet.
• Switch the air purifier on and choose fan speed with the fan speed knob on the back of the unit (see Fig. A). The Wood's GRAN 900
lets you choose between 4 fan speeds; a higher fan speed means higher air flow and faster purification but also slightly higher
power consumption and noise level. Please refer to Fig. A for more information.
• When the air purifier is running, you can feel the air flow from the sides of the unit.
• For best results, leave the air purifier running continuously, even during the night or when you leave the house.
• The filters in the unit need to be replaced regularly, at least once every six months. Read more about replacing the filter below.
• For best results, place the air purifier in the centre of the room. Make sure that the air flow isn't blocked.
4. Workings of your Wood's air purifier
The Wood's GRAN 900-series circulates the air through the room with two fans, taking in air from its front and exhausting clean air
from its sides. For optimum air purification, it is usually recommended that the air purifier is powerful enough to circulate the air
through the room twice every hour. This unit is therefore recommended for rooms up to 160m
a demanding environment, for example very dirty rooms or rooms 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. A demanding environment will also
affect how often you need to replace the filters in the unit. We therefore recommend that you check the filters regularly and replace
the filters when needed. Please refer to the filter chapter below for more information.
When the air is circulated in the room and passed through the ionization part of the air purifier, the particles in the air are given
a light electrical charge. When the air passes through the air purifier, the charged air particles are drawn to the Active ION HEPA
filter where they stick. This technique is not only very efficient, it also allows for a low filter density. 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 filters
of the same capacity.
Carbon filter (optional)
If the unit is equipped with carbon filters, the gases in the air are adsorbed by the carbon filters after the air has passed through the
Active ION HEPA filter. The carbon filters remove gases and unpleasant odour from the air. Place the carbon filters outside the Active
ION HEPA filters. Replace the carbon filters when they are expired according to step 1-5 below.
5. Cleaning and filter maintenance
Wood's air purifiers are easy to clean and maintain. If needed, use a damp cloth or vacuum cleaner to clean the outside of the air puri-
fier. Avoid using solvents or strong cleaners as this may damage the surface of the air purifier.
Filter change
The Active ION HEPA filters in the Wood's GRAN 900-series need to be changed regularly due to their ionization. To receive the full,
10 years warranty make sure to change the filters at least once every six months. However, the filters may need to be replaced more
often depending on the environment. The filters also have a status indicator that shows when they need replacing.
1. Switch the air purifier off and unplug it from the power outlet.
2. Open the air purifier by gently turning the top latch.
3. Remove the consumed filters.
4. Insert two new filters as marked by the arrows on the filter.
5. Close the air purifier and reconnect it to the power outlet.
Access the filter by turning the top latch of the unit. Please refer to Fig. B for more information.
6. 10 years warranty program
Wood's air purifiers are of the highest quality and capacity and that is why Wood's are able to leave as much as 10 years warranty on
all air purifiers. All you have to do is follow a few easy steps:
• Register your air purifier at warranty-woods.com
• Change the air purifier's filters at least once every six months.
• New filters can be purchased at your local retailer.
• For more information, please visit woods.se
NOTE: Make sure to save all receipts, even for the filters. These are needed for all warranty claims. If you don't wish to enter the
warranty program, you still have 2 years warranty on your air purifier. Please note that the extended warranty only applies to
the Active ION HEPA filters and not the carbon filters.
