Edgestar High Velocity Evaporative Swamp Cooler / Portable Air Cooler

Authorized Dealer

The EdgeStar High Velocity Portable Air Cooler (EAC421) is powerful and one of the best cooling portable air coolers for home use on the market today. Unlike smaller air coolers, this air cooler boasts the power to provide relief from the heat for an entire room (up to about 250 square feet, based on our product tests), and because it has oscillating louvers, the EAC421 is sure to cool everyone in the room. EdgeStar teamed a powerful (yet quiet) centrifugal fan with a honeycomb water curtain to outperform the competition. The Australian-engineered honeycomb water curtain allows more water circulation with less airflow resistance, and the centrifugal fan gently and powerfully throws a jet of air up to 25 feet - the longest air throw for a cooler its size.

The EdgeStar EAC421 portable air cooler offers features and value that the competition can't match. In addition to the above design features, the EdgeStar high velocity portable air cooler also features 3 different fan speeds, the option to add ice for additional cooling, a long-lasting 5 gallon water reservoir, a remote control, a fan-only setting, and the ability to operate as a humidifier. Plus, it only uses 250 Watts to operate - about 1/4 the energy required by most air conditioners.

  • Coldest Airflow:

    We tested this EdgeStar portable air cooler against other units currently in the market and its airflow was as much as 5°F colder than the best-performing competitor. The oscillating louvers allow you to distribute that cool air to everyone in the room.

  • Just Add Ice:

    The EAC421 gives you the unmatched ability to add ice, further lowering the internal water temperature and therefore the outgoing air temperature.

  • Room-Cooling Power:

    With its powerful centrifugal fan, osculating louvers, and honeycomb water curtain cooling system, this unit can provide cool relief to multiple people in rooms of up to 250 square feet

  • Environmentally-Friendly:

    Unlike portable air conditioners, this unit uses no freon and no CFC's- and it consumes 1/4 the power of and air conditioner

NOTE: This unit is not a portable air conditioner. We tested this unit under varying conditions and found it helped relieve heat in rooms of up to 250 square feet. However, if you need true air conditioning, please see our full selection of portable and room air conditioners
