    The EAC421 provides cool relief for rooms up to 250 square feet

    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

    Edgestar High Velocity Portable Air Cooler 4.2 5 32 38
    Works as described I was skeptical that this unit would do the job, but after reading all of the customer reviews, I decided to take a chance and purchase it. It cools two rooms in my home enough so that I and my dog are extremely comfortable. I have already recommended this product to a friend, who is also very satisfied with it. Excellent product for the price -- and it makes life comfortable here in the southwest. July 21, 2014
    Edgestar High Velocity Portable Air Cooler EAC421 I have been extremely pleased with the Edgestar High Velocity Portable Air Cooler EAC 421. I owned my first of this model and used it for more than 5 years before the motor froze up and said its goodbye. I recently purchased this newer model and it's equally as good, but much quieter. It has a couple of quirky additions that I don't care for as much - the clasp on the side door where you add water is sticky, the top lid doesn't lift well with the handle, I just push it down from the back of the flap and it opens smoothly. There is also some potential for losing the plug on the bottom since it's not attached - it was kind of hard to find and in a different location than the picture in the manual, but easier to use than in the last version of this model. It is much quieter than the last model - no trickle noises from water. It cools our bedroom at night and a very large living space during the day. There is flexibility for the amount of moisture that it puts in a room, keeping the humidity levels low and comfortable. I add ice in the top reservoir for additional cooling when it's really hot. One change I would recommend to the manufacturer would be to make the side handles more usable. When you try to roll the cooler, there really is no grip to hold onto making it rather difficult to move (something we do most days!) Also, the silver color is a little tacky-looking, but I imagine it will prevent the yellowing that happens when you have white plastic. To express how good a machine this is - we bought one. My dad and his girlfriend came to visit and each ordered one on their first day. Then my father-in-law was having health struggles because of the heat so we bought him one too. He loves it and is finally able to sleep without the heat-related health struggles. (Maybe we should get a commission for all those sales!) Thanks for the product. July 15, 2014
    Portable Air Cooler We live in a new house, regardless, the 3rd floor just gets too hot. This is a problem for many in our area. There just is not an easy way to install a traditional unit for many reasons. Prior to purchasing the air Edgestar Air Cooler my daughter was sleeping in the family room. It is simple to use, we pour water in with a gallon container and push start. The noise level is equivalent to that of a fan on high. Will be easy to put in a closet when the season is over.

    Very Happy with Unit I searched every place online that offered or sold evaporative coolers. When I came across this site and saw this unit for the price it was worth a try. I read all the reviews which is what sold me. This unit is wonderful! We have had some triple digit weather and I have not had to run my A/C in my window since I have gotten this. Even when not using the water/cooling function my master bedroom is so comfortable. The unit is a bit bigger than I expected so it does hold a lot of water. Make sure you have it where you want it because once its full it is not easy to move around on carpet. And man does it blow, I have only used the low setting which is plenty. It is louder than I would like but that is something I can certainly adjust to for the amount of cooling it provides. July 8, 2013
