What Is the 27.625×31.750×1.750 Exact Aluminum Foil Mesh Air Filter?

The 27.625″×31.750″×1.750″ Exact Aluminum Foil Mesh Air Filter is a premium, washable impingement-type panel filter manufactured by AMFCO. It is specifically designed to provide effective filtration in residential, commercial, and industrial HVAC systems, capturing airborne particulate matter and coolant mists. Its precise dimensions ensure an exact fit, crucial for preventing air bypass and maintaining system efficiency.

This filter operates on the principle of impingement, where airborne contaminants collide with and adhere to the filter media. Its unique construction features multiple layers of expanded aluminum foil mesh, arranged in a progressive-density pattern. Larger openings at the air entrance gradually transition to smaller openings at the air exit, ensuring that particles are trapped throughout the entire depth of the filter, rather than just on the surface. This design contributes to a dust arrestance of 53% average at a rated airflow of 350 FPM.

As a reusable filter, it offers a sustainable and economical alternative to disposable filters. Its durable aluminum construction allows for repeated cleaning and reinstallation, significantly extending its service life and reducing operational costs and environmental impact.

How This Aluminum Foil Mesh Filter Is Constructed

The AMFCO 27.625″×31.750″×1.750″ Exact Aluminum Foil Mesh Air Filter is engineered for durability and effective filtration through its thoughtful design and quality materials. Each component plays a crucial role in its overall performance and longevity.

Frame

The filter’s robust frame is constructed from .030″ thick aluminum, providing exceptional structural integrity and corrosion resistance. The frame features mitered corners, which are securely fastened with pop-rivet(s) to ensure a rigid and stable structure. Additionally, drain holes are strategically placed in three corners of the frame, facilitating efficient water drainage during the cleaning process and preventing water accumulation.

Filter Media

At the core of this filter is its advanced media pack, composed of multiple layers of expanded aluminum foil mesh. This media is arranged in a 7-ply, progressive-density configuration. This means the layers at the air entrance have larger openings, gradually transitioning to smaller openings at the air exit. This design ensures that airborne contaminants are trapped throughout the entire depth of the 1-3/4 inch filter, maximizing dust holding capacity and maintaining consistent airflow.

Face Grids

Protecting the delicate filter media and enhancing the overall strength of the filter are the 24 gauge aluminum face grids. These grids are positioned on both sides of the media pack, preventing damage from air velocity or handling. Their sturdy construction ensures the media remains in place, contributing to the filter’s long-term performance and reusability.

Installation Instructions for Aluminum Air Filters

Proper installation of your AMFCO 27.625″×31.750″×1.750″ Exact Aluminum Foil Mesh Air Filter is crucial for maximizing its performance and ensuring the efficiency of your HVAC system. Follow these guidelines for a secure and effective setup.

Before Installing

• Verify Dimensions: Double-check that the filter’s exact dimensions (27.625″×31.750″×1.750″) match the requirements of your filter slot to ensure a snug fit and prevent air bypass.
• Inspect Filter: Examine the new filter for any signs of shipping damage or manufacturing defects before installation.
• System Power Off: Always turn off your HVAC system at the thermostat and the main power switch (if accessible) before attempting to remove or install filters.
• Note Airflow Direction: While aluminum mesh filters often do not have a specific airflow arrow due to their design, it’s good practice to note the orientation of your existing filter if one is present.

Installation Steps

1. Turn Off System: Ensure all power to your HVAC unit is completely off.
2. Locate Filter Slot: Identify the filter access panel or slot in your furnace, air handler, or return air duct.
3. Remove Old Filter: Carefully slide out the old filter. Note its condition and orientation.
4. Insert New Filter: Slide the new AMFCO aluminum foil mesh filter into the slot. Ensure it fits snugly without forcing it, and that there are no gaps around the edges.
5. Secure Access Panel: Close and secure the filter access panel or door.
6. Restore Power: Turn the power back on to your HVAC system.
7. Check Operation: Briefly run your system to confirm proper operation and airflow.

Notes by System Type

• Upflow Systems: Filters are typically installed in a vertical slot, often at the bottom of the furnace or in the return air duct leading to it.
• Downflow Systems: Filters are usually placed in a horizontal slot above the furnace. Ensure the filter is fully supported to prevent sagging.
• Horizontal Systems: Filters are installed in a horizontal slot on the side of the air handler. Verify that the filter is securely seated and supported across its entire length.
• Grille/Return-Air Installations: For filters located behind a return air grille, ensure all clips, latches, or screws are properly fastened to hold the filter firmly in place.

Cleaning and Maintenance of Washable Aluminum Filters

The AMFCO 27.625″×31.750″×1.750″ Exact Aluminum Foil Mesh Air Filter is designed for easy cleaning and long-term reusability. Regular maintenance is key to preserving its filtration efficiency and extending the life of your HVAC system.

Washing Procedure

1. Remove Filter: Turn off your HVAC system and carefully remove the filter from its slot.
2. Rinse with Water: Using a garden hose or a strong stream from a faucet, rinse the filter thoroughly. Start by rinsing against the direction of normal airflow to dislodge larger particles, then rinse with the airflow to flush out remaining debris.
3. Apply Mild Detergent (Optional): For stubborn grease or heavy grime, you may apply a mild household detergent (e.g., dish soap) to both sides of the filter. Allow it to soak for a few minutes.
4. Rinse Thoroughly: Rinse the filter again with clean water until all soap residue and dirt are completely removed and the water runs clear.
5. Shake Off Excess Water: Gently shake the filter to remove as much excess water as possible.
6. Allow to Air Dry: Place the filter in a well-ventilated area to air dry completely. Ensure it is fully dry before reinstallation to prevent mold or mildew growth.
7. Reinstall: Once completely dry, reinstall the filter into your HVAC system, ensuring proper fit and orientation.

What NOT To Do

• Do NOT use harsh chemicals, strong acids, caustic cleaners, or abrasive brushes, as these can damage the aluminum media and frame.
• Do NOT bend, twist, or distort the filter frame or media, as this can compromise its structural integrity and filtration effectiveness.
• Do NOT reinstall the filter while it is still wet, as this can lead to mold, mildew, or corrosion within your HVAC system.
• Do NOT use high-pressure washers or power washers directly on the filter, as the force can damage the delicate aluminum foil mesh.
• Do NOT attempt to repair damaged filter media; a compromised filter should be replaced to ensure proper filtration.

Cleaning Frequency Guide

The ideal cleaning frequency varies based on environmental conditions and system usage:

• Residential Use: Typically every 1–3 months. More often if you have pets, allergies, or live in a dusty area.
• Commercial Use: Every 2–4 weeks, depending on the volume of foot traffic and external air quality.
• Industrial Use: Weekly or bi-weekly, especially in environments with high particulate loads, coolant mists, or heavy airborne contaminants.
• High Dust Environments: Inspect and clean more frequently as needed to maintain optimal airflow and filtration.
