Amaircare 4000HV 'Airwash' Filter Change Instructions

Please read and follow the directions below to replace any filter(s) on your Amaircare HEPA Air Filtration System.


Removing the Filter Assembly 1. Unplug your unit from the power supply outlet. 2. Unlatch retaining clips and lift off lid. Some units will also have a safety screw that needs to be removed before the lid can be lifted off. 3. Turn HEPA filter counter-clockwise and lift out. 4. 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.

Hepa Cartridge Replacement 1. Remove and carefully discard the old HEPA Cartridge. (Filter Assembly) 2. Install the new HEPA Cartridge. (Filter Assembly) see: ‘Re-Assembling the Unit’

	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.

Re-Assembling the Unit 1. Place the foam ‘O’-ring into the unit on top of the Motor Assembly (if a new foam ‘O’-ring is available, use it in place of the old one) 2. Place the Filter Assembly into the unit, on top of the Motor Assembly and firmly twist the Filter Assembly clockwise until the filter is locked tight. 3. Place the lid back on top of the unit an clamp it down with the retaining clips. Replace safety screw if one was removed while opening the unit. 4. Plug the unit back in, and turn it on.
