Coleman Air Filter

Coleman air filter replacements are available at All Filters for a wide range of Coleman furnace and HVAC systems, including whole-house air cleaners and air conditioners. Coleman systems use 5-inch media filters in standard sizes including 16x20x5, 16x25x5, 20x20x5, and 20x25x5—designed to capture fine airborne particles before they accumulate in your ductwork or damage system components. Replacing your Coleman-compatible air filter on schedule maintains proper airflow, keeps energy costs in check, and extends the life of your system. Browse by part number or nominal size to find your exact replacement.

Shop Coleman Furnace Filter Replacements

Coleman furnace filters protect your HVAC system by trapping dust, dander, pollen, and other airborne particles before they reach the blower and heat exchanger. A clogged filter forces your system to work harder, increasing energy consumption and accelerating wear on mechanical components. Regular replacement keeps airflow at manufacturer-specified levels, which is essential for both system efficiency and indoor air quality. AllFilters carries replacement filters compatible with Coleman furnace and air conditioner systems, available in the OEM sizes your system requires. Our filters are a reliable, cost-effective alternative to purchasing through an HVAC dealer—and with free shipping on orders over $99 and seven-day customer support, stocking up is simple. Find your filters for furnace systems here.

How to Choose the Right Coleman Furnace Filter

Start with filter size. Coleman whole-house compatible filters use 5-inch deep-media filters, and the nominal dimensions are printed on your existing filter's frame. Common sizes include 16x20x5, 16x25x5, 20x20x5, and 20x25x5 and you can often match by OEM part number. Next, consider MERV rating. Most Coleman systems are designed for high-efficiency 5-inch media, which typically performs at MERV 11 or higher. MERV 11 captures pollen, mold spores, and pet dander, making it a strong choice for allergy-prone households. Confirm your system's rated MERV range before stepping up to MERV 11 or 13. MERV 8 is also available.

FAQs on Coleman Air Filter

How often should I replace a Coleman furnace filter?

Regular Carrier furnace filter replacement protects the blower, heat exchanger, and coils from particulate buildup that degrades performance and shortens equipment life. Replacing every 6–12 months, depending on indoor air quality, maintains proper airflow for consistent comfort and lower energy costs.
Coleman whole-house systems use nominal 5-inch deep-media filters in specific widths and lengths. Compatible replacement filters are widely available by size and OEM part number. As long as the filter dimensions and depth match your cabinet, a compatible replacement will perform equivalent to the OEM product.
The Coleman Mach is a rooftop air conditioning unit in ducted ceiling installations commonly used in RVs and manufactured housing. Their unique sizes and shapes fit specialized systems for RVs and capture dust and debris before air enters the system, protecting the evaporator coil and maintaining airflow efficiency. As with all HVAC systems, replace Coleman Mach AC filters regularly.
The easiest way is to check the label on the box frame of your existing filter. It will show the nominal dimensions and often the OEM part number. You can also reference Coleman's part number (such as FS1620, FS1625, FS2020, or FS2025) to match directly. All Filters lists compatible replacements by both part number and nominal size for easy identification.
Coleman furnace filters use an industry standard single-use pleated media design that is not meant to be washed. Wetting the media disrupts the fiber structure and permanently reduces filtration efficiency. Attempting to clean and reinstall a used filter can result in reduced airflow, degraded filtration, mold growth, and potential damage to your HVAC system.
