Inspect and Pre-Clean Air Filter

What happens here

Start by removing the dirty air filter from its housing. Visually inspect the filter for any obvious damage, tears, or excessive blockages that might indicate it needs replacement rather than cleaning. Place the filter, open-end down, onto a stable surface like a sturdy bucket or directly on the ground. Gently but firmly tap the filter several times against this surface. This initial tapping helps to dislodge large, loose debris, heavy dust, and clumps of dirt from the filter pleats. Observe the amount of dust being released; this preliminary step is crucial for making the subsequent deep cleaning more effective.

Goal: Remove initial loose contaminants and assess filter condition.
