It's so hot in my house I am watching AC videos instead of sleeping.
That's the boat I'm in right now too.
Tell me about it. I'm in the central coast of california, close to the ocean with perfect weather.
Moriah Reinholz lmao
thank you for the measured review!!
We should try to build this by ourselves.. It can be a nice work to do... And wish you are having a good day today on this occasion of America's Birthday
i think the "lowest temperature achieved" was rather a maximum delta T the unit can achieve.
the problem with those units is that they will increase humidity by a bunch and in worst cases cause mold in the house if you cant properly ventilate the room (if you do all the heat comes back in again =/)
That is a complete waste of money. It is a miniature evaporative or swamp cooler. A swamp cooler needs to move a lot of air to work. I have a room size one and it is about ten times the size of that one and uses about three gallons of water a day. Any cooling you feel in that video feel is the fan it uses. A properly working swamp cooler lowers the air it draws in by about 20 degrees. They make out like it is revolutionary technology. Swamp coolers have been around as long as electricity has been around, that is over 100 years. They only work in dry climates like deserts or the western states. They don't work at all in humid environments like the Mid West or the East coast. It will work kind of in L.A. which is more humid than you think because it is close to the ocean, but not NY. They work great in Phoenix, until it gets too hot, they only lower the air they take in by 20 degrees, that means when it is 110 they are blowing 90 degree air. They are counting on that when everybody got central ac they stopped using swamp coolers and most people don't even know what a swamp cooler is. I asked a kid in Home Depot about a swamp cooler and he didn't know what one is, I got mine online. You tend to put them on the roof or in a window where they can take in dry air. They make the air a little humid, enough not to work, but not enough to cause mold. For example they take the humidity of a room in the desert from 30% humidity to 80% humidity. The air in the Mid West tends to run 100% humidity. For a swamp cooler to work it has to move a lot of air and has a big fan. A fan run off of a USB cord can't move enough air.
Ok, thanks for your input.
Try cross ventilating air, I tried one in my camper van with fresh air from under the dash passing the cooler through to the rear of the van were a computer fan draws air out from behind my fridge out thru the vent.
Woke up cool and fresh on a 33 degrees Celsius day.
Tried having cooler turned off on the next day for comparison and woke up sweating!
I am almost 50 (and always williing to learn something new) and never heard of this.. So ty for teaching m something I never knew of! I have considered a giant shop fan.. My friend has one looks kind of like the round home floor models but about X3 size.. lol. Like being in a mild tornado when it is just on low too! 😂😂😂
@@seewhaticando3885 Don't feel bad. I am older than you, not a lot older, but older. To me it means the things that things that kids read about in books, I watched on the 5:00 news. The weird thing is I am older than the people I used to think of as old. This looks like an evaporative cooler which uses a fan running through a wet membrane to cool the air from the evaporation of the water. I think it uses the principle of convection cooling, it is a good idea to Google convection cooling. Sweat uses the principle of convection cooling. I used to work outside in Phoenix in the summer and literally drank three gallons of water a day and would sweat it all off. I could wear the same shirt the next day because it evaporated as soon as I sweated it. The evaporation of the sweat is what keeps you cool. Guys in the South with big sweat stains on their shirts aren't getting cool from the sweat. That is why when you get out of the pool you are cold. The drying of the water from your body makes you cold. Evaporative cooling has been around longer than electricity. People used to hang wet sheets on the porch in the summer and then sleep out there. The drying of the sheets cooled the air. Evaporative cooling requires a lot of air, something that small might cool your head a couple of feet away. Evaporative cooling requires a dry climate. It won't work in humid states east of Colorado. If you want a better value look for evaporative coolers on Amazon. They need more air than the manufacturer says. I recommend one about 3x what the square footage says. If it says it will cool a small room, it will cool a large closet. The thing is they work best with fresh air, like an open window and they need somewhere for the air to go, like another open window. They had lots of evaporative coolers in Phoenix. The dry climate there is good for evaporative cooling. If you live east of Colorado a desktop fan will work better and be much cheaper. The mid-west and east coast is much too humid for that to work.
@@seewhaticando3885 One of the nice things about evaporative coolers is they have fans that keeps the air moving and air conditioners don't. Fans make it feel about 5 degrees cooler. I have air conditioning in my apt. I had to buy a fan for each room. Cooling is a big deal in Phoenix. You are always researching ways to reduce your electric bill, and it always was 450.00 in July.
Good review and test of the unit.
Unfortunately I bought a couple of these that were marketed under Cool Air. Everything with this unit is exactly the same as the two that I bought. The fits unit lasted about 2 months before the water intake got clogged and it didn't cool anything. Used it as a personal fan for a month or so.
The second unit lasted all but 2 days before it wouldn't turn on.
While it worked, it did a good job of cooling my space at the computer work area. Not sure wher ethis is made but, I'll wait to see if another product that is more reliable comes on the market.
Thank You for the review and test. Very good report.
A mini swamp cooler. How COOL! I have central air and keep it set to 68F. I live in the high desert in Oregon and the humidity is extremely low, I think today is supposed to be 14% so a swamp cooler is an attractive alternative to AC around here. Happy 4th and try and stay cool if you can, thanks for the video!
Happy 4th George. My house was built in the 1800's. Even had a coal celler. No central air here. My ex-house, where my ex-dog, and ex-pool lives has central air and a heat pump. Lol. Nothing is forever, eveything changes. No one gets out alive.
won't this type of water sponge cooler make the room all humid ? ps: why did you dump the dogo ?
Holy shit Oregon has a high desert? I'm looking that up right now I'm intrigued.
Read your bio, thank you for your service, And sorry to hear about the CHF!! You have an audience out here that loves what you do, thank you sir!
Thanks
Pretty cool gadget, happy 4th!
*Absolutely love tThis works pretty well for it's little size **Fastly.Cool** my bedroom I learned to soak the filter in ice water for best resultsThis is a lifesaver when the power goes out over a three day weekendhis thing. **Fastly.Cool** and air purifier perfectly this machine We set it up in the low air circulation basement where the dogs hang out (man cave too) and it made a HUGE difference in air quality.*
Happy 4th man! I actually thought this unit ran off a peltier module at firsthand. Upon watching I discovered that it works with the same principles that the cooler we use at work operates. We’ll take ice bags and put it in the water to obtain dramatically lower temps. Just melts so fast in Kentucky. Lol 😂
We are in the same part of the country my friend. Been over 90 last 5 days.
can you try it on a hotter day and see how well it works?
Swamp coolers don't really work here in the south as it is just too humid but in my filament dry box it will be 86f but 10% humidity and I stick my hand in it and it is very cool in there so swamp cooloers, like this one, would work in very dry climates.
From the time that you place your order how long will it take to receive your articair ,yesterday I placed my order 08/05/2020 how long does it take to receive my unit ?
Hey! Would this thing be good for cooling the inside of a gaming cabinet?? Or the humidity it release would be an issue..??
The consoles are getting pretty hot in there
No, way to humid.
yes...finally smart reviewer uses thermometer to test cooler.
Does notta for dehumidification. It can harbor mold, but good if you live in dry hot climate.
Thank you for the video, it was very helpful. Could you tell me how far away from the unit that the cooling experienced? And how long does the 2 cups of water last before you have to refill?
The water level depends on the speed you use. It down't last all that long if the unit is working properly. My experience with this cooler is not so good. bought two (2) units and the first one lasted about 2 months before the water intake got clogged. Wasn't able to resolve the issue.
The second unit last two days (2). It wouldn't turn on after that....Threw both of them away and chalked it up to "education is not cheap learning experience.
Does this thing breaks the laws phisics? Where is the heat going? Does it magicly disepear or is is it just blowing heat on the other side plus the 3 watts of heat. Sounds like it would heat up the overal temperature in a room.
We had a swamp cooler in our kitchen window 39 yrs ago when we lived in Kansas. It had a big, noisy fan. Because of the humid climate, it did not help all that much.
Yep, swamp coolers are better for dry environments, I'm in the Free State, South Africa, it rained all weekend, and today, on Tuesday, humidity is back to only 10% (lol), I think using swamp coolers in humid areas will likely lead to mold in the house, which is a bad thing!
Same, the summers here are so humid swamp coolers do next to nothing. Plus the toilet tanks in my house sweat enough as it is so I don’t need to be adding to the humidity in the air. I think I’ll stick to my window ACs.
I use 2 fans to flow air in my bedroom and a third on my tiny bench to extract the fumes from the solder. But this could do the job with less power, replacing one of the fans
is this particular cooler still available? if so a link would be appreciated
I purchased four units, three of which are liquid from the bottom of the device, the company ignores from my emails. I would not recommend the connection with them at all.
Imagine a PC cooling fan pulling air across a wet piece of expanded foam, then blowing it out into the room and you have this unit in your mind. It does have a small impact on the air leaving the box (the 7 to 8 degrees here is representative), but even in a small room (about 9' x 9') the overall cooling is minimal. It runs about 4 hours on a fill. If you can locate it say near the head of your bed with the air flow directed onto you, it can be of help in getting to sleep. Or if you can locate it near a fixed location (like a computer work location or reading chair), it can be of some benefit - but only in a relatively low-humidity location.
Paul how is the air output what kind of volume does it give out is it like a fan
It's about what you would expect from a 5V fan. It's been in my son's room for a week and he loves it. It does increase the humidity slightly, but it also lowers the temperature by about 7-8 degrees and that is substantial.
learnelectronics we can try using a fairly bigger motor.. Example a 12v motor,with a high current rating of 2A..that might be better
I've got mine today, working in low mode for 6 hours, and it will reach 7-8 I guess. It's a personal device, like a PC, is for you only, not to cool a room. So far, not bad, i would say for 29.99€.
Still working well? Are you in a humid climate?
I think the Professional Air Conditioning guys are the ones with the Negative feedback.. for the cost it's amazing
I think swamp coolers work great in DRY ENVIRONMENTS, I've seen many people test these with like 70% ambient humidity (lol) already in their areas. These babies are for dryyyyyyyyyyy areas, like
Happy 4th Paul, Question have you looked at getting a usb logic analyzer or already have one?? A few years back I got the LHT00SU1 from banggood and while the "recommended" software kinda of worked. I found a open source program to be better for me called Sigrok - PulseView. I'm still saving up my pennies to buy an O-scope and a bench power supply. Thanks Rick
Rick I did a review on that same unit a few months ago. I too was unimpressed with the software.
A swamp cooler will work good with low humidity
Did I miss the actual brand name of this unit?
Swamp cooler. Bought a big one some years ago. Made the room sticky. Hated it
Where do you live? They work well in the desert.
Hello is it thé original artic air or the copy ???
Copy
save your money. The Arctic Air units are so poorly built they won't last past a month or two. The connector on the unit alone will fail in a short period of time. You have to be within a foot or 2 at the most to feel anything as the fan is pretty weak. Spend your money more wisely, go to a Home Depot and pick up a larger unit with a larger fan and water tank if you want things to work
mine works fine love it, piss off
Lee Rothman has mine for 7+ months still blowing great!
hello thanks uploader , one thing though in the booklet it says that this is also a humidifier witch we all know thats the last thing
we need in a hot already full humid summer condition , Correct me if wrong but if we poor very cold icy wather or dry water into the thank
it will probably be more efficient
Where do you get this dry water you speak of :D
What is "dry water"??👺
Dry ice maybe
Could you use Ice water? What happens?
Yes
Could this make the whole room cold?
No. Those personal air coolers are only intended to cool an area up to 3 ft away.
It is hot here also! I t was 86 degrees American in my bedroom yesterday . with the AC on and fan. I gotta get moved! I have thought about building one of these. But much larger. There is so much humidity here I don't know how well it would work! Along with a dehumidifier. Likely quite well. With power use. Ac may as well be used! The evap cooler could be used with less power when there isn't much humidity, when I'm moved it will be much cooler there. I'm in a mobile home. With no shade! A temporary home since my house burned. It's time to move!
JAMES! Since the 70's A swamp box and humidity don’t go together
Bruce Woods yea that's what I was saying. Use a dehumidifier to dry the air in my home then this to help cool it. But if you were to do that. I may as well use AC to cool. It may work in spring when it isn't as humid it may be OK. Plus it isn't as hot then! The best thing here. Is shade or AC. Or both. Maybe live in a cave!
If you live in a humid climate a swamp cooler won't work. When they do work they use a lot less electricity than a.c. essentially the same as a fan. They are essentially a fan and evaporation of water causes the air blowing through them to cool. When water evaporates it uses heat. It is not the water that cools the air, but the evaporation of water that cools the air. When you sweat it is not the sweat that cools you, it is the evaporation of the sweat that cools you. That is why they say it is a dry heat, in a humid heat sweat doesn't evaporate and you don't get cool.
Im.also.from.Pittsburgh
take it apart!
It looks like Arctic Air from As seen on TV.
is 24°C is Hot!!!???
Faaak
i woodbe sneezing like hell at That Temperature..
I Get Sweat Without any movement at 36°C
at Summers It Reaches 43-48°C And Those Air Cooler Are Only Support to middle Family..
it cools like less 6°C at Peak at Ambient Temperatures
Old time swamp cooler
Does it work
I need your help
It works for keeping one person cool. It will not keep a room cool.
Tnx
How much air temperature that gives ?
And does it works yet,
Does you replace filter or how many months or day it takes
You're doing a test in a room that is already 77 degrees. we don't know what the humidity is in the room that would have been a very important factor. But that's it if it's didn't do kind of a good job. I would put it outside in the dogz house to keep him happy.
And HAPPY INDEPENDANCE DAY!!! I changed my name a bit. Just in case you haven't seen it before. I am wondering if you know of Adam Welch's channel. He is working on a diy BMS. For lithium ion batteries. I was wondering if you would be interested in helping me with a project like it. I can't do anything with a computer at the moment. About all I can do is solder . simple stuff like that. I can offer some funding. And you can make videos of it if you want. Just an idea. Thanks
77 is hot? we have hit over 90s few times this week. with humidity in the 50%-80% range, last thing i want is more moisture in the air. in the south, we just do fans. and would use a heater version of this for humidity in the winter.
in order for it to be a proper AC, it would need to do a heat exchange and remove hot air out of the room. thinking peltier device, fans, and ducting.
77 in my house with the ac on? Yes thats hot. It was 95 today and has been over 90 the 5 days in a row.
looks like ad I just saw for something called polaire.. I mean down to the buttons on the top it is identical..lol
I suggest you monitor the room humidity. These coolers work using the latent heat of evaporation of water. If the weather is hot and humid, it will not make much difference to room temperature. I don't recommend running in a room with electronics as the high humidity will result in corrosion of metal parts, and worst case water on circuit boards if dew point is reached.
Prolonged use with poor ventilation may result in the growth of mould on absorbent materials, such as wall paper and unpainted wood and plasterboard.
Some types of mould may represent a serious health risk, there is a particularly nasty species called aspergillus niger.
Check out moldpedia, this has details of the dangerous moulds and links to evaporator air coolers.
Its for my son's room. Thanks for the info.
learnelectronics these really only work in very dry heat. When it is already humid, the water will not evaporate very well and will quickly change back to liquid water releasing the heat energy it absorbed as it turned into vapour. I suspect there may also be a risk of growing legionella, the cause of Legionnaires Disease, if the filter and water container is not well maintained, though this is pure speculation on my part. It is possible the filter used to hold the water for evaporation has a antibacterial treatment, such as silver loading to stop such things growing on it.
But my comments about damp and mould I am confident are correct, as I have practical experience with a similar unit, this used a water dipped carbon foam filter with air blown through it.
You might like to run some tests and check how room humidity changes as it runs.
Like all these air quality improvement devices, there always seems to be a draw back if the price is low. Do you remember those negative ion generators that was a fad a few years ago? They did improve the air quality, providing they did not generate too much ozone, but at the expense of the room decor.. The big drawback was they negatively charged the dust in the air which promptly discharged on any grounded surface, such as the room walls, turning them a premature black colour. The clue was that the corners of the room would remain clean, showing the original colour as a narrow band. This is because of the electric field in oblique angle, (90 degree) corners is lower, making the charged dust less attracted to them. This is the reverse of the point discharge effect.
I did a quick bit of research and found that aspergillus fumigatus is even more dangerous than the black mould aspergillus niger.
Both are found growing in damp rooms, commonly in bath and shower rooms, both can result in fatal pulmonary disease.
I think that manufacturer suggests that you change the filter every 6 months or so
Skyline4017 the filter may contain anti mould and bacteria chemicals. I cannot comment on it or how long the filter remains safe.
It must be assumed that the manufactures are fully aware of the potential problems and take the necessary steps to protect their customers.
I found the instructions that came with mine(Rovus Arctic Cooler) it looks identical as the one in the video...they say that they recommend cleaning the filter and the insides of the water container once a week...and to change the filter every 6 months,even sooner if you notice that device isn't working properly.
You got the point about humidity...it can be a problem and a health risk if not carefull
Sorry for my bad english i hope you can understand what i meant to say :)
So, how did your son like it?
He was quite happy
We're also in the middle of a heatwave. Boy our climate really seems to be screwed up! I considered a similar unit but didn't fancy the increased humidity especially here in Scotland! I suppose that wee unit won't do much harm especially in drier parts of the world. Proper air conditioning units are just so expensive and we seldom need them over here, normally!
No no, be careful, I ordered a product called Arctic Air, it has leaked water, defected, but the company has not wanted to replace. I must just throw it.
Put crushed ice in it! Bet it gets cooler!
@mad ass You get a minor benefit from the sensible heat of the additional heating of the cooler water (maybe 3% or 35 btu/lb water), but the latent heat of vaporization of the water (roughly 1000 btu/lb) is far more that that. The air mass far exceeds the water mass so the effect on the water evaporation rate is very small.
@@billcameron7375 Not to mention that your freezer had to work to make that ice, by adding heat to your room.
Becareful of the fake ones, that looks like the fake one I have, it blew my electric.
Swamp coolers don't work in high humidity.
Is it powerful?
Not really. Its good for one person
Sort of like a desk fan but cooler?
NO!!!! and it has a paper filter which is always in water and will quickly MOLD potentially making you sick. NOT a good idea
Ofcourse ist powerful!
If your in danger and you need help it will become optimus prime or bumblebee based on the RGB color that u use 🤓

try ice water with ice inside the tray
I am here in China , I tested evapolar which is similar it is so bad and returned it to the shipper
Ok, thanks for sharing that. Im not familiar with that brand,
Waste time with small air conditioner
Air Conditioner??? Not even close LOL
In my country, 77f is cold. Lol
Cold here is -20F

I’m sorry to hear that.
that is 37 W heater, not cooler, you can not cool enything with electricity if all of the parts is in the house, you can just heat, I was thinking that you know simple stuff of electric and termodinamic..... your fridge is also heating, not cooling your house
You have no concerns over pouring water into a device like this on your bench with all of your electronic test equipment right there? Seriously?
No, I'm pretty steady.
I just saw the commercial for this scam product. Doesn't work at all
Yes it does.
it not work leak water
I hope you are not going to sit inside the cooler. Show the temperature of the area and not inside the cooler. ICE + Fan = cool air. That's common sense. What you should have reviewed is... How long does it maintain the same temperature which will at least help someone before buying this thing.
One year down the road. It will keep one person cool.
@@learnelectronics okay man.. :=)
Try filling it with Isopropyl Alcohol (Caution Extreme Fire Hazard). I would try this outside in a safe place.
Doug or just saturate yourself with Petrol and playing with matches either is good to change your temperature.....
What if i fill it with beer?
why not put some ice cubes in there?
It hardly makes any difference with how the science behind it works. As long as it's somewhat cool water, it should work in the right conditions.
Charlatan ! attention ne fonctionne pas ⚠️⚠️⚠️⚠️⚠️⚠️⚠️
Scam product.
None of these work. They all work of the same concept. You got 2 choices. Buy one and be ready to take it or send it back or go buy a $2 dollar store fan. Same cooling results. Total POS.
Wow, a knock off of a total shit product. What will they make next?
Works well for needs.
