Without using refrigerants, it relies on evaporative cooling to lower temperatures naturally. It’s eco-friendly, quieter (below 55 dB), and easier to move than bulky AC units.

Best Portable Aircon For Large Spaces
- Massive airflow cools big indoor/outdoor spaces quickly

If you’re in need of cooling for a garage, sunroom, or big family room and don’t want the cost or hassle of a refrigerant AC, this little air cooler clocks in at an impressive 3,500 CFM airflow, with five fan modes, a massive 114 oz water tank, and 90° vertical plus wide horizontal oscillation. Its eco-friendly design avoids refrigerants and uses evaporative cooling to reduce temperatures several degrees—if humidity levels are moderate.
