Honeywell HRFB1 Premium Odor Reducing Air Purifier Pre Filter
Item #: HONHRFB

For a pre-filter that goes the extra mile in performance, the Honeywell HRFB1 Premium Odor-Reducing Air Purifier Pre Filter available at Allergy Be Gone does more than just eliminate irritating particles from the air. It also employs activated carbon and zeolite to deodorize the air much more effectively than a standard carbon filter could. And it also keeps your air safe from potentially harmful gases, including volatile organic compounds like Ammonia. For the best maintenance of freshness, you are advised to change the pre-filter every three months.
