part of the air in the aircraft is recycled and that means that it must be cleaned. for that we used The air purification filters.

The air purification filter is the air filter for the lower recirculation system.
The 2 assemblies contain 3 high efficiency particulate absorbing (HEPA) filters. The filter system cleans the air pulled from the mix bay by the related
lower recirculation fan.

The outlet of the filter assembly goes to the related recirculation fan in the
related pack bay through a high flow shutoff valve.
The filter weighs 40 pounds (18 kg).

Reason for replacement: scheduled (every 3000FH)
