Product review (4 stars): Skuttling along nicely
Stupid me!  I didn't know our humidifier contained filters, let alone that they had to be replaced periodically.  This news was imparted to me during a home inspection so the pressure was on to get a replacement, once I had cleaned out the bit where the filter goes with white vinegar.  There was a considerable amount of white, chalky sediment to be scraped off and cleaned up before I could do anything else.  These filters were half the price that Sears were quoting me and took about 2 weeks to arrive. They were both a little dented (maybe look at the packaging materials, please?) but are working just fine.  I would have liked basic instructions for installing them (remember, I am the pink, sparkly girl) as I had no idea where to put the wick thing or if there was a right or wrong way up.  This was solved by a little internet research.
For price and delivery, great job!
