Product review (5 stars): Humidifier filter
Exactly what I needed for my whole home humidifier. I was concerned at first, because my model says that it needs filter HC26P  2001, however, I could only find on the manufacture website, which included a hefty shipping price. I ordered this hoping it was the same, and from what I can tell, there is no difference between the models. I have been using it for approximately a month now with no issues. Free shipping with prime is great!
