Product review (1 stars): Even if they cost $5 a set they would still be horrible, at $18-25 a set it's criminal
Utterly deplorable filter quality!  Even if they cost $5 a set they would still be horrible, at $18-25 a set it's criminal.  I changed the filters exactly one week ago to the day and they're now only wicking water up less than 1/3rd of the way, yet they haven't turned orange at all.  After changing them I let them fully absorb water to the top before turning the humidifier back on.  I always use Holmes humidifier water treatment with every tank fill and always refill the tanks well before they're empty to make sure it never runs dry.  Even with all that the new filters only lasted one week set to 50% humidity on the low speed setting and now it's struggling to keep the humidity at 50% in a 12'x12' room where my guitars are kept (the whole reason for the humidifier).  Horrible product!
