Baldwin PA3957 FOAM Foam Pre-Filter Blanket for PA3957 Air Filter Element

The Baldwin PA3957 FOAM is a foam pre-filter blanket designed specifically for use with the Baldwin PA3957 oval air filter element. Acting as an outer wrap, this foam blanket provides an additional layer of filtration to capture larger airborne particles — such as dust, dirt, and debris — before they reach the primary filter media, helping to extend the service life of the underlying air element.

Key Features:

• Foam pre-filter blanket designed to wrap around the Baldwin PA3957 air filter element
• Adds an extra stage of filtration to catch coarse contaminants before the primary element
• Helps extend the service interval of the primary PA3957 air filter
• Oval filter profile to match the PA3957 element geometry
• Sold individually; also available in cases of 12
• Baldwin part number: PA3957 FOAM

Baldwin Filters are engineered to meet strict design parameters for durability and filtration performance. The PA3957 FOAM foam blanket is the correct OEM-style pre-filter accessory to pair with the PA3957 element in demanding engine air filtration applications.
