Product review (5 stars): so that changing them is easy and fast
Exactly as described. The plastic tabs that hold them in place are fixed into the filter, which has a flexible plastic mesh cover, so that changing them is easy and fast.  For the past 2 years, the only comparable filters I have found were not the same quality (had sharp metal mesh and separate plastic tabs with hooks that had to be carefully reinserted any time the humidifier was cleaned).These filters fit my Bionaire humidifier perfectly and are well-made.
