Product review (2 stars): "Holmes" filter
The filter as delivered was not really Holmes branded and the built-in meter on my Holmes humidifier has read "replace filter" from day one using the replacement filter. I think the replacement filter really doesn't work well because now the water consumption of the humidifier in operation is about half of what it used to be with the original"factory" filter. I have the brochure from the original humidifier package and there's a web address to order "genuine" Holmes filters. That will be my next step to see if I can get the humidifier's efficiency  back to what I hope it can be.
