Product review (5 stars): The best filter for Honeywell HCM350 Humidifier!
This replacement filter output more than the original filter that arrived with my humidifier. As other reviewers noted, this filter is not as stiff as the original, but that doesn't lower the performance. In fact, this replacement puts out 1.5 times the moisture as the original filter, and is less in cost.

This filter works so well that I'm slightly annoyed that I have to fill the reservoir container more often. I use it in my home on the weekdays. On weekends, I drive several hours to my parents' home. Even on the lowest humidifier setting, this replacement filter would empty the entire reservoir in less than 30 hours. I actually had the problem of coming back to a dried out filter when I returned.

The problem with the dried wick, is once you re-wet it, it outputs a moldy smell. To try to salvage the filter, I froze it and tried to thaw it out (wondering if I could just freeze it at the end of the work week and thaw it at the end of the weekend). This did not work.

For my particular case, I've decided to try cutting it in half and seeing if that will last an entire two days. That way, I won't have to try replacing the filter each week, which would be WAY too expensive. I could use the other half after this one pulls enough allergens out of the air.
