Product review (1 stars): Not really extended life
I just replaced my original filter (which I was using for the past two and a half months) last week and already this filter has developed a pinkish color on it as well as some brown around the edges.  I make sure that I air out the filter every morning and we only use the humidifier at night.  I am very disappointed because I thought that this filter was for an extended life.  I do not think that within a week I would be seeing changes to the filter.
