This demonstration guide answers one field question about pollen mats that appear in weeks not months. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with filter restriction versus a new filter. That reading separates pollen mats that appear in weeks not months from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the air filter as the primary path. If it is in spec, do not replace the air filter just to complete a parts list.
Repair the failed system
The usual correction is the air filter, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about pollen mats that appear in weeks not months.
Stop before you make it worse
Do not blowing a paper filter out from the dirty side. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the air filter is corrected, convert the visit to a broader diagnosis rather than stacking parts.
