Opening the cabinet

1. Unplug your unit from the power supply outlet.

2. Open the front door of the unit by pushing up and lifting outwards, to gain access to the filter compartment.
(you may need to remove a safety screw from the top of the door first)

Removing the HEPA Cartridge

1. Turn HEPA filter counter-clockwise and lift out.

2. Remove the HEPA cartridge from the unit. NOTE: The sponge (or carbon) pre-filter and the HEPA filter will contain contaminant's. Remove them slowly from the unit in order to avoid dusting.

Replacing the Foam Pre-Filter

1. Gently pull the foam pre-filter upwards to remove it from the assembly.

2. To replace with a new or washed* pre-filter, carefully spread the foam filter around the outer edges of the filter assembly and gently pull it down to it's original position (covering the exposed steel mesh)

* In order to increase filter life, foam pre-filters may be hand washed, allowed to dry, and re-used. Over time and increased washings the filter will eventually need to be replaced.

Replacing the Inner Blanket

Caution: When completing the following steps, please use extreme care not to inflict pressure on the underlying HEPA filter when replacing the Inner Blanket

1. Look inside the Filter Assembly to locate an end of the Inner Blanket.

2. Without applying pressure directly on the HEPA filter located behind the Inner Blanket, fold the ends of the old Inner Blanket in and remove it from the unit.

3. Insert the new Inner Blanket inside the HEPA Cartridge with the edges overlapped by at least one inch. Once it is in position gently spread the Inner Blanket against the HEPA filter until the two ends of the blanket meet.
