To remove the cabin air filter on VW Polo 9N, you look under the passenger foot well and see the cabin air filter cover.
Slide the locking tabs towards the center of the frame then pull the cover downwards.
Pull the filter down and either use compressed air to clean the cabin filter or wash it. You can reinstall a brand new filter too if you prefer or you cleaned it too many times. Usually you would clean it 2-3 times.
When you install the cabin air filter back into the filter frame observe the markings on the cabin air filter that say air flow direction or arrows.
The air flows from the passenger door towards to center of the car so you should install it the same way as the old filter was installed or if the old filter was installed wrong, replace the cabin air filter and install the new filter correctly.
Washing the cabin air filter is not ideal but only rinsing the filter with a bit of pressure from a garden hose might make it last longer.
New filter is the best way then compressed air then last option is to wash the filter.
