Buying Guide
- What size space do you need to cool? Look for BTU ratings that match room square footage. Higher BTU is better for large rooms but can consume more energy.
- Is self-evaporation crucial? Models with self-evaporation reduce or eliminate manual drainage in typical conditions, but some environments may still require occasional drainage.
- Do you need quiet operation? Sleep modes and low-noise fans improve comfort in bedrooms and home offices.
- How important is mobility? Check caster wheels, handles, and ease of setup, especially if you plan to move between rooms.
- Smart features and controls? Apps, remotes, and timers help automate cooling and optimize energy use.
- Maintenance and accessories? Ensure window kits, hoses, and drainage options are included or easily sourced.
