Description
AMFCO 6” × 16.5” × 0.25” Exact Reusable Open-Cell Foam Air Filter
The CMP04-00013108-RevB-1 is a 6” × 16.5” × 0.25” exact-dimension washable open-cell polyurethane foam air filter manufactured by American Metal Filter Company (AMFCO). Open-cell foam filters operate by impingement — airborne particles contact and adhere to the foam cell walls as air passes through, providing effective large-particle pre-filtration at very low pressure drop. The filter is washable and reusable: rinse with water, air dry, reinstall.
CMP04-00013108 Rev. B is an OEM part number cross-reference. This filter is manufactured by American Metal Filter Company (AMFCO) to match the factory foam filter specification and is available as a direct aftermarket replacement. No minimum order is required.
Exact-dimension foam filters are cut to precise tolerances matching OEM equipment filter tracks. The 6” × 16.5” × 0.25” actual dimensions install without field trimming or shimming. Applications include equipment cooling intake filtration, specialty HVAC pre-filtration, and aftermarket replacement for equipment originally fitted with open-cell foam filters.

Applications
OEM Equipment Replacement
The CMP04-00013108-RevB-1 is dimensioned to match original foam filter specifications in equipment that shipped with a factory foam pre-filter. Equipment manufacturers use open-cell foam as the primary intake filter where low pressure drop is more critical than high-efficiency particle capture — common examples include small fan coil units, packaged terminal air conditioners (PTACs), dehumidifiers, and specialty ventilation equipment. Replace the original foam filter with the same exact-dimension AMFCO unit.
Electronics and Electrical Enclosure Cooling
Open-cell foam filters are used in the intake vents of electrical enclosures, control panels, UPS systems, and industrial electronics to prevent dust ingestion while maintaining adequate cooling airflow. The low pressure drop of foam media is essential in gravity-convection or small-fan cooling circuits where available static pressure is limited.
Specialty HVAC Pre-Filtration
In applications where a low-resistance impingement filter acts as a first-stage pre-filter protecting downstream higher-efficiency media from rapid loading, an exact-dimension foam filter provides large-particle dust arrestance at the lowest possible resistance penalty to the system fan.

Cleaning and Maintenance
Washing Procedure
- Remove the foam filter from the equipment and take it to a utility sink or outdoor area
- Rinse thoroughly with warm water, working from the clean face toward the loaded face to push captured particles out — do not crush or wring the foam while saturated
- If heavily loaded, soak in a mild dish soap solution for 5–10 minutes, then rinse completely until water runs clear and no soap residue remains
- Gently squeeze (do not twist or wring) to remove excess water
- Allow to air dry completely at room temperature before reinstalling — do not use heat sources; elevated temperatures degrade polyurethane foam
- Reinstall only when fully dry; a damp filter restricts airflow and may promote microbial growth in humid climates
What NOT To Do
- Do not wash in a dishwasher — heat and detergent will degrade the foam cell structure
- Do not dry with heat — hair dryers, heat guns, or direct sun exposure at high temperatures cause the foam to shrink, stiffen, or crumble
- Do not use petroleum-based solvents or strong degreasers — these dissolve polyurethane foam on contact
- Do not install while damp — a wet foam filter restricts airflow, can cause corrosion on adjacent metal surfaces, and promotes microbial growth in humid environments
Replacement Indicators
Replace the foam filter when the cell structure begins to crumble or tear during normal handling, the foam no longer returns to its original shape after washing, or large sections of cell wall have collapsed. A foam filter that no longer maintains its dimensional profile will allow bypass airflow around the filter edges.
Frequently Asked Questions
What is a washable foam air filter?
A washable foam air filter is an open-cell polyurethane foam element that captures airborne particles by impingement — particles adhere to the foam cell walls as air passes through. Unlike disposable fiber filters, the foam element can be washed with water and returned to service repeatedly, typically providing several years of service from a single unit.
What are the exact dimensions of this filter?
The CMP04-00013108-RevB-1 measures 6” × 16.5” × 0.25” exact. These are the actual cut dimensions — there is no nominal-to-actual conversion. Order this SKU when the equipment filter opening matches these dimensions.
How do I clean this foam filter?
Rinse with warm water, working from the clean face outward. For heavy loading, soak in mild dish soap for 5–10 minutes, then rinse completely. Gently squeeze out excess water and allow to air dry fully before reinstalling. Never use heat to accelerate drying and never use petroleum solvents or strong degreasers.
How often should I clean the foam filter?
In clean office or low-use environments: inspect every 3 months, wash every 6–12 months. In dusty industrial or commercial kitchen environments: inspect monthly, wash every 1–3 months. Hold the filter up to a light source — reduced light transmission indicates particle loading that warrants cleaning.
What MERV rating does this foam filter have?
Open-cell polyurethane foam filters are not rated on the MERV scale. MERV ratings apply to pleated or fiber-based dry-test media per ASHRAE 52.2. Foam filters are impingement-type pre-filters used for large-particle capture at very low pressure drop — they are not designed for fine-particle filtration and should not be substituted for MERV-rated media where particle efficiency is specified.
Is this filter an exact OEM replacement?
Yes — CMP04-00013108 Rev. B is an OEM part number cross-reference. The CMP04-00013108-RevB-1 is manufactured by AMFCO to match the original OEM foam filter dimensions and is a direct dimensional replacement.
Can I order a custom size?
Yes. American Metal Filter Company manufactures foam filters to print specifications for custom OEM and aftermarket applications. Contact AMFCO directly for a quote on non-standard dimensions. No minimum order is required for custom sizes.
What is the maximum operating temperature for this foam filter?
Standard open-cell polyurethane foam is rated for continuous use up to approximately 180°F (82°C). For applications near heat sources or in non-air-conditioned environments in hot climates, confirm the foam media is suitable for the expected inlet air temperature. Prolonged exposure above the rated temperature causes foam degradation and dimensional loss.
