Product review (4 stars): I wish they'd left in the stripe.
The Holmes Cool Mist Humidifier is really a great humidifier.  I've used one in my daughter's bedroom for 3 years now.  The filters are treated with an antimicrobial agent to keep harmful bacteria at bay longer.  We usually go through a filter a month, on average, during the winter months.  My only complaint is that they took out the blue/red strip that used to tell you when it was time to change the filter.  That really came in handy.  Overall, though, the filter and the humidifier work great.
