These are by far the best furnace filters weve ever used. Filter Buy makes filters that are more expensive and might be necessary for those with severe pollen allergies but for most households the MERV 8 is just fine!
[This review was collected as part of a promotion.] Very fine furnace filter product: with a change of said filter every three months, the house is dust and allergy free; the filter does trap dust far better than the previous lesser quality filter. Ron
The filters seem fine enough, but the structure of the filter box seems kind of flimsy. The spacers? between the accordion pleats weren't spread out and so a lot of the pleats are on top of each other or not evenly spaced. It's like they were rushed in manufacturing.
