Product review (1 stars): would not recommend
This filter fit correctly but would not wick water all the way to the top, hence the need to flip it with every refill.  I've had mine less than one month and it will no longer carry water more than a third of the way up rendering it useless.  The filter I replaced had a blue outer layer and lasted the entire season, I would not buy this one again and would not recommend it.

**edit**  ok, so I'm going to eat my words and re-order this model since it's either that or trash the whole humidifier.  But I will be looking for other options before next heating season, shame on Honeywell for changing the design of the original that benefited the consumer
