How do I change the Peugeot 308-filter?

To replace the salon filter, first, it is necessary to open the bonnet and on the passenger's side to remove the four clips that hold the element of noise insulation. Then we need to remove the clips and remove the noise-proofing material (fragile, easily broken). Under the latter is a plastic filler with a small handle to be removed. Then you need to change the filter and reverse the details.
