- CommonFilter warped from washing and not fully drying flatWashable filters can warp if wrung out or dried on an uneven surface.
- PossibleWrong replacement filter purchasedSimilar-looking generic filters don't always match the exact dimensions needed.
- PossibleDebris in the filter housing blocking a full seatDust buildup in the housing itself can prevent the filter from sitting flush.
What to do
- Check the filter for an arrow or marking indicating airflow direction and orientation.
- Wipe out the filter housing to remove any dust or debris preventing a flush fit.
- If the filter is warped, try gently reshaping it or let it dry fully flat next time before reinstalling.
- Compare the filter's dimensions to the original if using a replacement, checking width, depth, and shape.
- Try rotating the filter 180 degrees to see if it seats differently.
- Purchase the manufacturer-specified filter model if a generic one isn't fitting correctly.
- Once seated properly, confirm the housing door or lid closes and latches without force.
