ShueBee 2-Pack MERV 13 Air Filters, 20x20x4
Retailer ratings4.6 · 13 ratingsOne of these is on the shelf, waiting its turn in the inspection queue. That price is the most it will list at, never more. Anything we find comes off it. An inspection can also find a unit we will not sell, and then this one never goes on sale.

We move it to the top of the inspection queue and email you the results, usually within a few hours.
Nothing is held for you. When it goes on sale the first person to check out gets it, and emailing you first is the head start.

About this item
These replacement filters use a collapsible frame design made up of four side panels and two folding filter elements, allowing flat storage before installation. Once expanded, the frame locks into a rigid structure meant to fit 20x20x4" furnace filter slots, with an actual measured size of 19.99" x 19.99" x 4.59".
The filter media is rated MERV 13, intended to capture fine particles such as dust, pet dander, smoke, and PM2.5 down to 0.3 microns. The listing states the filters are built from high-efficiency synthetic material meant to hold more dust and last longer than standard filters.
Installation is tool-free: the filter element expands, the plastic panel slots align with the frame edges, and clips lock it into place before sliding into the furnace with the airflow arrow facing the unit. The listing suggests replacement every 6 to 12 months depending on air quality needs.
