Product review (4 stars): Holmes Humidifier Filter for Sunbeam Humidifier
We bought a humidifier earlier this year. Because we live in a small town an hour away from a city with brand name stores, I shop primarily online.  These filters are not fancy colored, but they keep humidity in our home and the humidifier needle in the "blue" area over 30 days.  I have found that purchasing filters in multi-packs is a major savings to our budget account.  The retail bargain stores do not sell this type of item in 5-packs or 10-packs, and the savings makes a major difference.
