    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 35 43
    Edgestar Portable air cooler I read the reviews on this product (Portable Air Cooler EAC421) and was convinced enough to buy it. It's a fairly painless setup but the Owner's Manual is somewhat vague on some functions especially in the specifications portion, seems to rely on your use of common sense (over cautious beware) but you eventually get the idea and it all seems to fall into place. The lettering on the remote doesn't have enough contrast especially in low light conditions, flashlight recommended. I am using it in a small area and even without using the cool mode, water circulation, it keeps the area comfortable (I used it on some 90 degree days). Not as dramatic as an regular AC but keeps the area cool. Also the fan is noisy but livable. The service from Living Direct was great and prompt. Yes I would recommend this unit. August 8, 2014
    Good stand in for broken swamp cooler We panicked when our swamp cooler pump stop working and ordered 2 of these. Very helpful for personal cooling; but with our poorly insulated vaulted ceilings and open floor plan, unable to significantly impact interior temps in main living area. So when sleeping we run our swamp cooler on high vent only (at night typically in 50-60s) to bring house temps down into the low 60-70s. Does cool south facing 12x14' bedroom well in the evening (when outside temps are still in the high 80s) allowing us to slip into a cool bed even when rest of house is actually warmer than outside temps due to accumulated solar gain. Obviously we like it very cold! We use ice to maximize cooling. Also helps a lot in the kitchen when cooking, especially /w fan on high, in swing mode. Only down side is noise level impacts our ability to converse and hear TV, (not as much as cooking noises do), but is not unpleasant (nice white noise effect). Initially had a funky plastic/chemical odor, that disappeared after several days of airing outside and running 2 batches of water through it. I have chemical sensitivity disorder and suffered no ill effects once odor stopped. Great for the price and convenient, much more environmentally friendly than A/C. Bonus: you can use as a 'humidifier only' when furnace is running. August 7, 2014
    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
