MaxMERV9 Washable Furnace Filter vs Washable Electrostatic Media-Type Furnace Filter

Both are permanent, washable electrostatic filters, but they target different systems. The MaxMERV9 is a 1-inch panel filter rated MERV 9, the highest MERV claimed for a washable filter, with a rigid aluminum frame and corrugated grid. The MEDIA-TYPE filter is a thick-frame replacement for media cabinets in Honeywell, Carrier, Trane and similar units, rated MERV 8 but with far higher peak arrestance (94.7% vs 83.2%), much lower initial resistance (0.12" vs 0.252" WG) and more than double the dust holding (165 vs 68 grams). Owners of both praise fit, build and easy cleaning; both draw complaints about bent filters in shipping and slow, made-to-order delivery. Buy the MaxMERV9 for a standard 1-inch slot where filtration matters most; buy the MEDIA-TYPE filter if you have a media cabinet and want low resistance and long service between cleanings.

• Choose the MaxMERV9 if you have a standard 1-inch filter slot and want the highest MERV rating available in a washable filter, with a stiff aluminum frame that holds its shape.
• Choose the MEDIA-TYPE filter if your system uses a thick media cabinet from Honeywell, Carrier, Trane, Aprilaire or a similar brand, and you want low airflow resistance and long dust-holding capacity.
