Product review (4 stars): Bigger, better, faster more (than honeywell)
Much better than the Honeywell brand, all day, every day, and for much, much longer.

When the filter gets funky I put a cup of bleach in 2" of sink water and roll the filter slowly around to kill EVERYTHING.

This highlights the one and only complaint I have about this filter. I wish the metal reinforcement inside the filter were ABS plastic because the metal reacts badly to both bleach and vinegar (or lemon juice). The bleach actually makes the filter absorb water even faster, and make the filter even more effective, but the aluminum mesh corrodes badly, so at some point I no longer feel comfortable having air blowing past aluminum oxide as that could be a health hazard. I'm not saying it IS, as it might not be, but at some point I feel more comfortable replacing the filter instead.
