Unistar 4-in-1 Desktop Fan/ Cooler/ Humidifier/ Ionic Air Purifier, DF158
No installation! Save 95% on your AC electric bill with this 4-in-1 cooler/ionizer/humidifier/fan with a power comsumption of 38 Watts only.
This year, beat high energy costs with the Kaito Air-Cooler-Ionizer-Humidifier,
yet the room temperature is reduced by as much as 12 F in the direct air way. The built-in fresh air
anion generator releases streams of negative ions that attract dust and other allergens down and out of
the air you inhale. Air feels as fresh as after a springtime rain. It uses the water to cool and humidify the air,
ideal for desert areas such as California, Nevada, New Mexico, Colorado, Arizona and etc. The drawer-type water tank
capacity is about half a gallon, which means the cooler can run for 8 hours continuously or even longer.
To achieve higher cooling efficiency, you can even mix water with ice or with included ice packs.
There are no expensive filters to buy; just rinse
the permanent filter. Other features include three air speed: H/ M/ (more…)










This unit is nothing to write home about but I guess it serves its purpose. I purchased this fan for my small studio apartment. To be honest I’m slightly disappointed. If you are looking for a medium sized unit for an office or small apartment this unit does help.
That being said, don’t be misled by the air cooling feature. This is not an air conditioner and will only give you slightly cooler air flow. The fan on high isn’t really powerful. The two reusable ice packs are nice so that you can rotate them in. The timer control works well so that you can set it to run when you leave or go to sleep and it will continue to run for 1, 2, 4, or 8 hours. The setup and controls are very user friendly. You can get this unit up and running within 2 minutes of opening the box.
I don’t think I would buy this unit again. I’d probably look for something with a higher speed fan or something that cools the air a little bit better.
This unit works reasonably well in my small bedroom that has large windows (no windows that open however) that face into the morning sun. The room can get quite hot and stuffy with no way to circulate air from nearby sources. This room does have darkening curtains to cut down the sun load and I am sure that gives the cooler some assist. I live in the pacific northwest state of Washington where the humidity is moderate. This cooler sits on a table at the foot of the bed. I ice it up and put it on high breeze and oscillate and it works quite well. I can sleep comfortably. That being said, I have awoken to some very hot mornings and the unit blowing warm air which makes me more uncomfortable. At this point if I add cool water and ice and the ice packs it will cool the room down fairly quickly. I don’t mind the hum of the motor noise and the wind sound effects. It helps mask annoying noises and is actually pleasing to me and helps me fall off to sleep quicker. I am not sure how effective the ion option is. It is not recommended for large rooms or very hot areas but for a small room, office cubicle or dorm, that you need to cool down to a comfortable degree, it works fairly well. It is small and streamlined and easy to port from room to room. It looks attractive. It tends to cool an area directly in front of it from about 1-5 feet. Oscillation will get you a few feet at the sides as well. The timer is a nice plus. I would not recommend this unit to cool down a large room…it simply won’t do it. But for a small room space and ice water added it should be effective enough to do a decent job for the money.

perfect for personal cooling
I bought this little unit for my office desk, which is in a completely mirrored and barely insulated building, giving it the “ant in magnifying glass” effect in the afternoons…
I was tired of sweating to death in my hot cubicle, and all my old fan did was blow the hot air around. This unit did the trick. I’m not sure it would cool off an entire room in a home, but it works nicely in my cube. Also, because it humidifies and oscillates, it doesn’t dry out my contact lenses like my old fan did. It’s a little noisier than the fan, but not enough to be heard by my fellow cube-dwellers. The little freezer bottles that come with it are just that, really little and don’t stay frozen for long. I find I have better cooling results when I refill the water reservoir with ice cubes and water a couple of times a day.

Satisfied
I was very satisfied with my purchase of the Unistar 4-in-1 desktop fan/cooler/humidifier/ionic air purifier.
The unit will hold up to three small dry ice packs.

Perfect for Your Prison Cell!
OK, maybe not for your prison cell, but a space of equal size. It’s small, it’s barely effective, it’s noisy, but it does have some cooling properties.

waste
This thing wouldn’t cool a room in a dollhouse, much less a room in my house. And, the shipping charges were outragious.
