The McPherson Reusable Air Filter is a permanent 14x20x1 HVAC filter with a washable MERV 8 polyester layer inside a corrugated aluminum mesh and aluminum frame. Instead of tossing a pleated filter every few months, you rinse this one and put it back. The metal frame and mitered corners are built to hold shape through repeated washing, and MERV 8 captures dust, pollen, pet dander and lint without choking airflow in most residential systems. It suits pet owners and anyone tired of buying disposable filters, though it filters less finely than MERV 11-13 media and needs a real wash rather than a quick rinse to stay effective.

Owners of reusable metal-frame filters like this generally value skipping disposable replacements and the sturdy frame. Complaints center on the washing routine and on MERV 8 being a modest filtration level.
This is a washable, reusable 14x20x1 air filter for residential AC units, furnaces and HVAC systems. It has a MERV 8 rating and captures dust, pollen, pet dander, lint and other common household particles without restricting airflow. It is made in the USA.
The filter pairs corrugated aluminum mesh with a MERV 8-rated polyester layer inside an aluminum frame with mitered corners. The frame doesn't bend or warp. The aluminum frame and mesh are built to last as long as the HVAC system. The polyester layer is consumable and holds up for 5 to 10 years, depending on air quality and cleaning frequency.
It slides into a standard 14x20x1 filter slot without tools, and arrows on the frame show the airflow direction. To clean it, remove it and rinse it with water from a garden hose or shower. Let it air dry, then reinstall it. It can be used in apartments, RVs, mobile homes and other residential HVAC systems.
