Product review (5 stars): Better than the original
The honeycomb design I think works better than the corrugated design of the filters that came with my humidifier. The original filtered never got my humidity over 33% and these easily get to 45% haven't tried higher. They don't quite fit the same, they are a little snug but not problematic. They also have plastic spikes going into the filter to secure it to the frame which works much better than the glue that was supposed to hold the original together.
