evaCHILL Portable Air Conditioners - Portable AC Unit - Small Personal Evaporative Air Cooler & Fan for Bedroom, Office, Car, Camping, Grey

I cannot say enough good things about this. It has saved me in the heat since my ac is down in my apartment. Yes it’s only meant to be directly on you but it will cool you down significantly. Don’t listen to these reviews saying it doesn’t work. It does! 12/10

No good 👎👎👎

Update....dropping down to 3 stars because after a year the fan is unusable as a bedside fan. The first problem I had was the fan control just stopped. Further investigation shows an issue with one of the pcb traces. I fixed that and it worked for a while until the noises started. A rattle developed somewhere in the fan making it unusable for a bed fan. Also... Evapolar has poor quality control of the replacement media. 50/50 chance you'll get a good one or one that smells like feet. The product is an excellent concept, but lacks in reliability. I always thought the desktop evap coolers were gimmicky, and they mostly are, until I saw this one that actually uses media and not just a soaked sponge/mister. Remember, this is NOT an air conditioner. Performance and efficiency will depend on your environmental conditions. You can only cool down the the wet bulb temp, but it's not 100% efficient so it'll be a few degrees above. Positives: - Design and Build quality on this are excellent. The unit looks good and is well thought out.... This the price. - Noise -- this is by far the most quiet of any fan I tried. That are no annoying rattles or motor harmonic. Just the sound of the fan which has a pleasant white noise sound at all speeds. - No mist, true evap design. This will eliminate any "white dust" that comes with the low cost desktop coolers. Negatives: - I wish the water tank was slightly larger, at speed 2 I get about 5 hours. I'd like one hour more. - the louvers are very loose and may not stay in position at higher fan speeds. All in all a great purchase and I will be buying more to replace other fans in the house. Yes it is more expensive but I personally think it well worth the cost for the quality.

The compact base is stable. Even with the fan is on high it doesnt wobble or slide once placed on smooth surfaces

Bought last night to survive a heat wave near Seattle with no air con. I wasn't sure if it would work in my area, since we were at 60% humidity-- Swamp coolers don't work well in high humidity areas, and I didn't know if that was too high. I have a small room thermometer that was reading 82F in my room at 10pm when I was getting ready to go to sleep. Placed the evachill on my headboard and let it do its thing for an hour, then placed the thermometer in front of it. It read 75F, plenty cool for sleeping. Actually got cold in the night (didn't measure then) and had to grab a blanket. Literally when it gets this hot at night, I usually sleep in a tent in the yard. I think I won't have to anymore, this is great! I'm not seeing anything close to 25 degrees cooler as claimed, but I do live in an area of decent humidity. I would not be surprised if it performs even better in arid environments. I would say though, have reasonable expectations for <$100 unit-- this only cools about 3 feet directly in front of it. Put it on your desk or headboard, you will feel it and it will make a difference. Expect it to cool a room or two people sitting in different directions, it's just not made for that.
