2. Key Features to Consider

• Usage: Decide if you need a fixed or portable unit based on where you’ll use it.
• Noise Level: For bedrooms or quiet spaces, choose a cooler with silent operation.
• Budget: Balance between features and cost. Desert coolers offer high performance but cost more, while personal coolers are budget-friendly.

4. Maintenance and Care Tips

• Regular Cleaning: Clean the water tank, cooling pads, and exterior regularly to prevent mold and odor.
• Water Quality: Use clean water to prevent mineral buildup. Consider using distilled water if tap water is hard.
• Storage: Empty the tank and dry the cooler before storing it during off-season months.
• Cooling Pad Replacement: Replace pads when they become hard, brittle, or ineffective.
• Check for Leaks: Inspect and fix any leaks in the water tank or pipes to maintain performance.
