LPAC intake air passes through how many filters?

Explanation:
Two filters are used. The intake air for the LPAC goes through a two-stage filtration setup: a coarse prefilter to catch large dust and debris, followed by a high-efficiency final filter to remove finer particles before the air enters the compressor. This arrangement protects the compressor from damage and deposits while keeping the pressure drop reasonable. Using only one filter wouldn’t provide adequate protection, and having more than two isn't typical for LPAC intakes and would add unnecessary resistance and maintenance.
