11 ft. x 18 ft. with 10 ft. ceiling non-insulated garage.
First 24 hrs.
80 -90 degrees temperature.
Product worked perfectly out of the box, fan is strong even in lowest setting, when cooling is turned on, fan power lowers.
Freezing 2 Ice Packs
2 Ice Packs included need 24 hrs of freezing before they solidify.
Ice Packs lasts 1 hr. each after 24 hrs of freezing.
Using regular ice cubes & cold water
Followed instructions & did not fill water tank to maximum, about 1/4 inch below maximum level with about 1/2 liter of ice cubes.
Using cooling setting significantly cools the air coming from the unit, you can feel it even in low setting. Once wet pad was soaked with cold water, air became moist and soft, very pleasing air blast that cooled the space to what felt like low to mid 70''s.
Using cooling setting creates a good amount of moisture in the space
Water tank filled with cold water & ice 1/4 inch below max line lasted 3 hrs before refill in 89 degree weather with 71 % humidity.
Next 72 Hrs
80-90 degree temperature
65 - 72 % humidity
2 Ice Packs & 1 Water Bottle frozen for 48 hrs.
Each Ice pack lasted 1 1/2 hrs.
Incorporated a frozen bottled water which is slightly taller than Ice Pack provided with unit, but still fits slightly tilted inside the water container. Frozen bottle also lasted 1 1/2 hrs
A good cooling solution would need more frozen water bottles or more ice packs so they could be replaced every 2 hrs. for continuous cooling days without having to use ice cubes.
Might be good to add more cold water to tank every 3rd Ice Pack or Bottle replacement, otherwise a 1/4 below Max level tank fill lasts 3 hrs. in mentioned temperature & humidity.
Water level sensor starts beeping at 3hr. mark to refill water tank, which is important to mention if you want the unit''s water pump to last.
Daily Cooling Schedule
I purchased this unit to cool an area in the garage for my dogs. Operating in the temperatures & humidity mentioned, garage side door is open at 8:30 am until 11 am or 12pm, then closed & unit is turned on for 3 hrs on low, then 3hrs. on medium fan speed, then 3hrs. on low or medium depending on the temperature in the garage after sundown.
This is an AIR COOLER, not an AIR CONDITIONER so I have used it WITH COOLING setting on at all times, otherwise it would just be a regular fan that blows whatever air temperature is available.
I am expecting the daily cooling setting & schedule to change as temperatures rise to 110 degrees in the summer here in the desert, changes might be putting more than one frozen packs in the container at the same time, adding more cold water & extending the cooling time.
While this unit might not have the handy thermostat other units have, it has a really good time setting that turns the air cooler off in mins. & hour increments, a thermostat in the unit could cost more and use more electric power. This Air Cooler is a blessing at the price with the power, convenience, efficiency, & comfort it brings.
95 - 99 degrees 67% humidity
2 blue ice boxes (included with unit)
3 frozen water bottles
1/4 Max line water tank fill
Fan on Medium Power setting
Anion, Cooling, Timer, & Swing settings all on
Garage with doors closed
Water tank refill every 2 hrs.
Ice pack replaced every 1 hr.
The CostWay Air Cooler EP23666 is the second or third size from the smallest unit. I wanted to test how well the unit would work with the garage door closed as they will be during peak heat days, & whether it provided enough cooling & airflow in the space for my dogs. I purposely angled the louvers downward about the waist down to provide cooling & airflow to specific areas where the dogs stay & the unit performs very well.
Waiting to test at higher temperatures to see where settings change, it might be 1 frozen box or bottle with Ice & water when temperatures go beyond 102 degrees, as the water tank can''t accommodate 2 frozen bottles. Using the 2 blue ice boxes together makes water cold for 2 hrs.
Long Cooling Periods
The water tank capacity does not go all the way to 7.5 hrs. don''t expect it to... other Costway Air Cooler models have larger water tanks but are also larger units.
Using the natural air or sleeping mode slows down water consumption but the best way is to not use cooling setting unattended overnight.
Sundown, Dusk, Early Evening
I open garage side door, use the high power setting for the fan to exchange air flow (hot air out, cooler air in) for 1-2 hrs. then use cooling setting for 2hrs, and repeat cooling if needed. Final evening setting is to run fan on medium with shut off time.

Cleaning The Water Tank
1 Month Continuous Usage with Unfiltered Water.
I checked the water tank of the unit today after 1 month of continous usage with cooling on & discovered the plastic water tank was lined with sediment film from our hard water here in the desert.
The sediments are very hard but not so difficult to clean off at this point.
I turned the unit off & using the drain plug at the bottom of the filling section of the tank ( the one closest to you when you pull out the tank -have a pan under the tank for draining) I drained all the water, tilted the unit so whatever water left in the reservoir (section of tank where water pump is) was also drained, then put the drain plug back in by pushing down until the rubber plug securely fit back in.
I unscrewed the small rectangular filter on the section divider of the tank & cleaned that with a soft scrubbing & dishwashing liquid then run it under hot water, to clear the filter.
taking a bowl of hottish water with a few drops of dishwashing liquid in the water & sponge, I softly scrubbed the water tank container to try & remove the sediments that were filming over the walls & bottom of the tank.
I scrubbed softly around the water pump inlets (diagonal holes on the sides of water pump) as well to clear sediments.
Filled the tank with enough hottish water to rinse all the the soapish debris & drained it all out by pulling the drain plug out again - have a pan under the tank for draining.
I re-installed the drain plug snug tight by pushing it in, slid the filter back in & secured the screw hand tight, then poured fresh cold water in the filling section of the water tank to 1/4 line mark of the 5 level marker making sure that all the water that goes into the tank passes through that filter and turned unit back on.
This might be a monthly thing for me to do since I use the unit with cooling setting everyday.
If the water pump starts working harder (gets louder) my next steps will be to unplug the water hose from the pump (the hose supplies water to the cooling pad that makes the air cool) fill the water tank to like 3 level, just enough water to run the air pump, put 3 table spoons of powdered citric acid in the water (get from AMAZON :-) or grocery store), turn on unit like you just put in fresh water & use cooling setting so the water pump cycles through with hottish water & citric acid for about 10 mins. turn unit off then drain all the water.
Plug the water hose back in to water pump connector, then re-fill water tank from the filling section of the tank so water filters through the reservoir.
