Product review (1 stars): From Amazon-Not a Honeywell filter !!!!
As titled in the Amazon.com web page, I believed I had ordered an HC-15 HONEYWELL Humidifier Filter. What I received was an RPS products knock off. Nowhere on the boxed filters I received  does it say Honeywell. Why? because it isn't!!! I'm not certain how this is advertised as a "Honeywell" product. Honeywell is a registered trademark, and to my knowledge not licensed to RPS Products "Best Air". Will the filters work? Perhaps.
