Product review (2 stars): NOT a genuine Honeywell Filter
For now, I'm giving this 2 stars because it is not a Honeywell filter. According to the box this is a "BestAir Extended Life Humidi*Wick Filter" that is compatible as a generic replacement for the HC-14.

I felt a little "bait and switched" because the title of this product implies this is a Honeywell product. It's not.

I've got 3 of these so I'll run through these and then update my rating.

UPDATE: Feb. 2009

I've now run through 3 of these filters. Don't let the earlier (2006, 2007) positive reviews of this filter fool you. It's far inferior to the genuine HC-14 filter with the blue outer covering. My humidifier was constantly running the entire 3 months I was using these filters. The humidifier could never reach or maintain my desired humidity level. Last week when I switched to the genuine filter not only did it reach my desired humidity level (40-45%) - it only needs to switch on half the time to maintain that level.

The difference in efficiency is astonishing.

Unfortunately, I couldn't find a vendor on Amazon selling the genuine filter. I needed to do a web search to find the product.
