Product review (4 stars): works and fits like original - will buy again
Pretty simple paper filter held together with industrial hot glue. This is basically the same filter that my MoistAir whole house humidifier came with. It fits inside the unit's plastic housing and fits like the original and does not fall apart. I use our unit only during the winter and am able to change the filter once per year. Ordering through Amazon I save enough to make it worthwhile.
