evapolar cooler

Coverage varies by model and is generally intended for personal spaces. Many listings show coverage under about 100 sq ft, and some smaller models specify coverage around 21 sq ft (≈2.5 m²) in the direction of airflow. Check the specific model listing for exact coverage.

Reported run times between refills vary by model but typically fall in the 3–8 hour range; some descriptions note about 6–8 hours on a single fill. Actual runtime depends on the specific model and its water tank capacity and settings.

Tank sizes vary by unit: smaller personal models list tanks around 27 oz (≈800 mL), while larger portable evaporative coolers in the results show capacities such as 1.3 gallons and 2.4 gallons.

They use evaporative cooling: incoming air passes through a water‑retaining medium so evaporation lowers the air temperature and adds humidity. Many models use an internal cartridge made from biodegradable basalt fibers that helps trap dust while retaining water for more efficient cooling and humidifying.

Noise levels vary by model and fan speed. Personal units report working noise roughly in the 25–50 dB range, while some larger portable coolers list a working sound level around 55 dB. Refer to the specific model’s spec sheet for exact noise figures.

Many Evapolar personal coolers are designed to be portable and easy to move, often featuring a carrying handle. Common power options shown in the results include USB power or USB‑rechargeable operation, making them convenient for desktop or small‑space use.
