Aircare 20x25x1 Washable Electrostatic Filter vs Web 25x20x1 MERV 8 Furnace Filter

The Aircare is the better-documented filter: a rigid galvanized frame, a stated 3/8-inch undercut, tight size tolerance, and a MERV 8 rating with capture down to 1 micron. The Web is a plainer washable MERV 8 filter with little published detail beyond its nominal dimensions. Both are reusable and save the cost of disposable filters over time. Buy the Aircare if fit and build quality matter to you; buy the Web only if you want a basic washable filter and its listed size matches your slot.

• Choose the Aircare if you want a rigid, precisely sized washable filter with a clear MERV 8 and 1-micron spec and a long track record of owner ratings.
• Choose the Web if you just need a simple washable MERV 8 filter in a 20x25x1 slot and don't care about frame rigidity or detailed specs.
