Buying Guide: Choosing The Best Down Draft Cooler Cover

Key questions to guide your purchase:

  • What are the exact dimensions of my cooler? Measure width, depth, and height precisely to match a cover that fits snugly.
  • Is the unit listed as “down draft” specifically? Some covers fit generic swamp coolers but may not seal well around down draft configurations.
  • What is the climate in my area? Regions with heavy rain or snow benefit from thicker 600D fabrics and reinforced straps.
  • Do I need easy access to pipes and wires? Velcro openings or adjustable straps help for maintenance without removing the cover.
  • How important is wind resistance? Elastic hems and windproof straps improve security in gusty locations.
  • What is my budget? Covers in this category vary by size; choose the best balance of coverage and features for your needs.

Material and Fit Considerations

  • Material: Look for heavy-duty 600D Oxford cloth for durability and water resistance.
  • Seams: Double-stitched seams improve longevity in harsh weather.
  • Fastening: Elastic hems and windproof straps help maintain a secure fit during storms.
  • Size tolerance: Many covers are designed a bit larger to allow easy installation; verify that the extra room does not expose the cooler to weather.

Installation Tips

  • Start by aligning the cover with the cooler’s top surface, then pull down evenly to avoid bunching.
  • Secure the elastic hem around the bottom and fasten wind straps in multiple directions to minimize movement.
  • For covers with openings for pipes or wires, ensure openings are properly sealed during severe weather.
