Product review (5 stars): Filter works, good price
Like another customer who has rated this product, I own a Honeywell HCM-890. That customer's claim that the filters do not work with this unit is a real head scratcher -- because in fact they work perfectly. How could it be otherwise, since the manufacturer claims specifically that the product works with the Honeywell HCM-890? Moreover, this is a good replacement for a higher-priced filter, so what's to complain about from any fair-minded customer?
