This Hunter replacement filter by Magnet fits the following Hunter Quietflo air purifier models:
- Hunter 37025
- Hunter 30010
- Hunter 30025
- Hunter 30040
The approximate size of the filter is 4-1/4" x 10-1/4" x 1-1/2. It is recommended that you change this filter every 6 months, depending on use. There are three different layers to this filter. The first part is the mesh screen that captures the larger particles before they make it to the thicker filtration media. The white filtration media captures smaller particles and keeps them from entering your indoor air environment. And the third part of the filter is the carbon layer. The carbon layer absorbs unwanted indoor odors like cigarette smoke, animal odors and cooking smells.
