3 1 portable air conditioner

Most portable air conditioners are multi-mode. Many are described as 3-in-1 (cooling, fan and dehumidifier/dry); some models are 4-in-1 and add heating to cooling, dehumidifying and fan modes.

Most models include built-in mobility features such as caster wheels and side or integrated handles for rolling between rooms. Units typically ship with window-installation accessories too—exhaust hoses, sealing/window kits, and connectors that support either vertical or horizontal windows.

Many units have removable, washable filters for easy cleaning. Several models also include self-evaporation or auto-evaporation systems to reduce manual drainage and routine maintenance.

Physical sizes vary from compact units to larger floor models. Based on the listings, heights range roughly from about 26.5" up to 36", with widths around 16–17" and depths near 19"; weights in the examples vary widely—from about 13.5 pounds for small evaporative units up to roughly 153 pounds for larger floor ACs.

Noise levels in the product details generally fall around 50–56 dB for several portable AC models. One evaporative cooler entry lists noise as "lower than 58 dB."

Common controls include digital/LCD control panels and full-function remote controls, plus 24-hour timers and sleep modes. Convenience features often include auto-swing/oscillation, built-in handles and caster wheels, included window-installation kits and exhaust hoses, removable/washable filters, and self-evaporation or auto-drain options on some models.

Some listings show Energy Star certification. Efficiency metrics in the details include SEER values (examples: SEER 16 and SEER 20) and an "Energy Efficiency Rating: 5-Star" on one listing. An ETL listing also appears for at least one model.
