5 Pack Evaporative Cooling Pad, 60″ x 12″ x 6″

Best for large-capacity swamp coolers and HVAC systems that require exact replacement size. Premium kraft paper construction with a honeycomb design delivers high water absorption and efficient air flow. Pack includes five pads, each measuring 60 in H x 12 in W x 6 in D. Use this option when your unit’s dimensions are in the 60″ tall, 12″ wide, 6″ deep range and you want a ready-to-install media for strong evaporative cooling.
- Best for large, high-volume coolers and multi-unit installations.
- Better for long-term durability in humid conditions due to kraft paper construction.
Caution: Kraft paper pads can be sensitive to prolonged exposure to moisture extremes; ensure proper drainage and avoid standing water in the media pockets.
DIAL 3437 Mastercool Cooler Pad

This pad is a straightforward option that emphasizes ease of use and durability. It is well suited for professionals who need a dependable replacement for standard evaporative coolers. The product is manufactured in China and focuses on robust performance in typical residential and commercial setups.
- Best for contractors and homeowners seeking a durable, no-fuss replacement.
- Better for units that match sizes around 40″ x 23″ x 8″.
Caution: Availability and compatibility depend on matching exact dimensions to your unit’s specifications. Check fit before purchase.
5 Pack Evaporative Cooling Pad, 48″ x 12″ x 4″

Best for mid-size applications requiring a compact, efficient media. These rigid kraft paper pads use a honeycomb structure to maximize water contact area and cooling efficiency. Each pad measures 48 in H x 12 in W x 4 in D, with five pads per pack for easy multi-unit replacements.
- Best for smaller or space-constrained coolers.
- Better for units built to the 48″ H dimension with standard 12″ width.
Caution: The thinner profile (4″ depth) may not fit deeper housings without clearance checks. Verify depth capacity first.
Champion Cooler Evaporative Media

Made in the United States, this pad is a solid option for mid-range to larger evaporative coolers. It emphasizes durable construction and compatibility with typical Champion hardware and assemblies. Use when you prioritize domestic manufacturing and a familiar brand footprint.
- Best for buyers prioritizing U.S.-made components.
- Better for standard mid-to-large sized evaporative systems.
Caution: Commodity sizing varies by model—confirm exact fit with your cooler’s dimensions before ordering.
DialManufacturing 3079 DIAL MFG INC Duracool Pad

Another Dial option, noted for ease of use and durability, aligning with U.S. manufacturing expectations for reliable performance. This pad suits units that benefit from straightforward installation and long service life, particularly in commercial environments.
- Best for projects needing durable, easy-to-install media.
- Better for standard industrial and commercial evaporative coolers.
Caution: Availability may vary; verify compatibility with your exact model and enclosure size.
Evaporative Cooler Pad, 35-1/2″ H x 36-1/4″ W x 2″ D

Designed for residential, commercial, and industrial applications, this pad provides a wider surface area with a modest thickness. It is a practical choice for systems needing a broader pad while maintaining a manageable depth for housing constraints.
- Best for multi-purpose installations requiring broad pad coverage.
- Better for installations with room to accommodate a 2″ depth.
Caution: Width and height must fit the cabinet dimensions; measure before ordering to avoid fit issues.
30″ x 36″ Synthetic Non Allergenic Pad

Tru Guard offers a synthetic, non-allergenic option that doesn’t shed fibers, making it a solid choice where allergen concerns are priority. Pre-cut for quick installation in standard-sized swamp coolers and smaller commercial units.
- Best for allergy-sensitive environments or where fiber shedding is a concern.
- Better for units that call for a 30″ x 36″ pad footprint with 2″ depth.
Caution: Synthetic pads can differ in water absorption characteristics from traditional kraft kraft pads; confirm the expected cooling performance for your climate.
Buying Guide: Key Considerations And Comparisons
- What size does my cooler require? Measure the existing media or consult the unit’s manual. Pad height, width, and depth must match the housing cavity.
- Material type: Kraft paper (high absorption, rigid, durable) vs. synthetic pads (non-shedding, allergen-friendly). Kraft is common for high cooling load; synthetic suits allergy concerns.
- Honeycomb structure: Denser honeycomb increases surface area for evaporation, improving cooling efficiency but potentially adding weight. Consider installation ease and airflow compatibility.
- Single-pack vs. multi-pack: Multi-pack options save on replacements for multi-unit setups. Confirm the number of pads needed for your system.
- Made in USA vs. import: Domestic manufacturing may matter for some buyers seeking local supply chains or perceived quality. Evaluate availability in your region.
- Durability and maintenance: Look for pads that resist clogging and maintain water flow. Regular cleaning and drainage help preserve performance.
Frequently Asked Questions
- Q: How do I know which pad size to buy for my swamp cooler?
A: Check your unit’s manual or measure the current media dimensions. The height, width, and depth must align with the enclosure. - Q: Are kraft paper pads better than synthetic ones?
A: Kraft pads typically offer strong absorption and durability for high-evaporative cooling, while synthetic pads excel in allergy-sensitive environments and fiber-free operation. - Q: Can I use pads from different brands in the same cooler?
A: Mixing brands is not recommended. Use pads with the same thickness and fit to maintain even water distribution and airflow. - Q: How long do evaporative pads last?
- Q: Do pads affect energy consumption?
A: Yes. Efficient pads improve evaporation rates, letting the system cool air more effectively with potentially lower fan speeds and energy use.
A: Lifespan depends on climate, usage, water quality, and maintenance. Inspect pads for fiber shedding, water flow, and signs of degradation and replace as needed.
