KuulAire PACKA45 Portable Evaporative Cooling Unit with 200 Square Foot Cooling Capacity, 375 FCM, Black

I read the reviews and was nervous about this, but went with it because I could afford. My elderly mother needs heat, but I die here, so I got this to cool just my room. The first time I used it I wanted to test it, so I left it on a high in an enclosed area for just the time it takes to shower and when I returned Whoo-ee! Hot and stuffy, has, like other reviews said. But now I will leave the window open (you only need a few inches of open window) and it works perfectly. I have it at the window about 6 feet from me and it feels like a nice spring breeze. It's 88 outside and 76 in my room, and there is no house a / c on. The side of the box specifically says it with an open window, so there is something to remember. I think the key is to have at least some airflow on the back of the machine, not a closed room. It will probably not always cool the whole room, especially in say Arizona in August. However, it will cool you. It is noisy, but less than my old window AC and the pitch is low, which is less irritating than a high frequency machine. You probably will not hear the dogs barking outside, but I can not find the noise to be a major problem. In addition, there are times where I really do not want to hear the neighbor's stupid dog anyway.

This cooler is small, but it is powerful. I took it out of the box filled the device with two gallons of water put it in, and cool air was abundant. And I use it in a room that is 440 sqft. It's 90 degrees outside and about 77 degrees inside.
And truthfully I do not find the device should be high for the amount of air it produces, and I have not disabled the low setting.
I'm pretty happy with my purchase and look forward to a cool summer with a lower cost than running my AC unit.
By the way, I live in the southwest, where humidity is low most of the summer.

PS: Hats off to the supplier since I received my order in two days ... Excellent service!

SPT SF-609 Portable Evaporative Air Cooler with Ionizer

I hate weeding through reviews of evaporative coolers, as it appears that most of the bad reviews are from people who have no idea what they are and what they will do a few are from people who can not follow basic instructions and there is only a handful of legitimate negative opinions, it is usually due to defective products.

I live in Denver, CO. It is dry here, and it's perfect climate for evaporative coolers. I have had the whole house cooler swamp in the former home, I have lived and know many friends with them. In my home, I have no option for a portable or window A / C air conditioning, which I spend most of my time in our finished basement and there is not a good option for the exhaust. Last summer we had offers for central A / C, but there are a lot more money than I want and I do not want electric bill that goes along with it. We have a whole house fan (not to be confused with a breath of wind) that we run into the early morning before it reaches 70 degrees, and that we are going again at night, usually after 9:00, or when it gets cold enough outside . Sometimes with an afternoon rain shower we turn it on before.

I purchased the evaporative cooler to complete whole house fan in reallllly hot days and / or mid-day when we we do not run it because it is warmer outside than it is now. House fan cools the ground floor a lot better than our basement because of the air flow from our cellar windows, as windows and cover we have. Also this summer I am pregnant with a due date 15 August and it does not help my comfort situation. Basically, an evaporative cooler exactly what I wanted and what is right for our situation.

Think of it as a fan on steroids. Cold air comes out of it. Today it's 88 degrees outside and the humidity is 16% ... a typical Colorado summer day. I have been cooler about 3 feet from me and 8 feet away from my husband. I have it on high and I'm actually getting cold. I feel the "swing" setting otherwise I would probably be shut down. It does not guzzle the water too fast and fill it once a day is enough, because I do not run it 24 / 7 I use one gallon jar to fill up faster, because it holds 10 liters (2.5 liters). I have an automatic icemaker in my fridge, so I have no problem running out of ice. I can not think of any features it lacks. It is not too noisy even at high - it's like a regular fan. There is no smell at all, but I can actually change the water frequently and follow the instructions for cleaning. Believe me smell things I can smell something from very far away because I have been pregnant. You can wash the air filter on the back, but do not use water to clean the wick. It's meant to be placed in direct sunlight to clean. I think that's why some people had problems with odors or mold. Follow the instructions, please. It has a remote control, timers, sleep modes, swing mode (just the fan blades inside the swing, not the entire drive), beep warning and visual indicators when it runs out of water (nice feature to avoid burn out the water pump), and an additional location of ice on top in addition to add ice into the water. You can adjust the blades on the front to control the air flow depending on which way you need vertically. It also has an ionizer, and you can run it as hell, if you want, so no need for another device just to get some air circulating.

All in all ... This thing does exactly what it says it will do. That's exactly what I wanted. It came together, which was a big bonus. It is only 17 kg and has built-in handles on the sides, so I can actually carry it upstairs himself, if it is empty, even super-pregnant. It is on wheels to make it easier to drive around when I do not have to take it to another floor. It was less than half what similar units cost the same tank size and air outlet.

I just have this thing for a week. I will be sure to update my review when I've had it for a while.

UPDATE 6 / 24 - I've found that when I run this thing on high for 8-10 hours a day, we need to fill it every day or every other day at least (depending on if I fill the max level ... I usually just add 1 liter when I fill it). But when I run it on medium or low and do not use it so much (more like 5-6 hours per day), it can take about a week without needing a refill. I usually do not bother to put on the ice for long unless it is a day with temperatures above 95 degrees and I want the extra cold air. The only thing I wish it had was a simple way to empty it if I want to move it up when it is not empty. But I do not think any model, I looked at was this feature (or at least it was not mentioned). It has never made the room feel oppressive, even without opening the window, and honestly I do not feel any difference in humidity in the room. Almost every day there has been less than 20% humidity outside, and I've never seen it get over 30% off. I'm still happy with this purchase, and stand by my 5 stars. I'm glad I got this instead of spending much more on a similar device.

SPT SF-610 Portable Evaporative Air Cooler with Ionizer

As I write this, it is 103 off with 29% humidity. Inside, without the central air conditioner running, it is 102 and 30% humidity. I filled up this gizmo, turned it on and the air comes out in front of the unit is 91 with 45% humidity.

As this cooler works by stopping the change of water into gas, open your window and let the air circulate, so that moisture does not build up to the point where you are in a sauna and sweat that - UM - a person who is in a sauna.

It will not cool an entire room, but if you want to be typing away on your computer, as I do, you will sit in one place. So sitting next to the refreshing breeze with an ice tea and you will be happy as a clam.

Here are some figures on how it works and what is reasonable to expect from this cooler. . .

Everyone knows that to generate steam, you use lots of heat to the water. You will be pleased to know that if you dip a towel in water and hung to dry, the liquid water turns into steam, and in the process absorbs heat. How much heat, you ask?

Water weighs about 8.3 pounds per gallon. Turn over one kilogram of water to steam, you must apply for a 910 kJ heat. Multiply 910 times 8.3 and you get 7553 kJ. So if you can trick a swamp cooler to evaporate a gallon of water for an hour, it will be (approximately) in a cool place as much as a regular window unit is estimated at 7500 BTU.
But this machine pretending to evaporate about half liter of water (about one pint) in one hour. A pint is 1 / 8 of a gallon, which is about 1 kg of water, so you can go out from this machine will cool at a rate of 900 BTU per hour, which is about 20% of what a small window air conditioner will give.

Yet this is evaporative coolers significantly more energy efficient than a plug-in AC unit.
This cooler draws 60 watts. Compare with a window AC unit that draws about 20 times as much power (1200 watts and above).
If electricity costs 10 cents per kWh:
This chiller will operate at 160 hours (one week) for $ 1.00
A window AC unit that draws 1000 watts will work for 10 hours for $ 1.00

Think about what you need to cool down before choosing a cooler.
If it's just you and you are not too fussy about sitting next to what is essentially a fan with a little chill, this will do the trick. But if you need to cool the entire room from 100 degrees F to 85 or below, you must definitely an ordinary air-conditioning.

Another note. . . by ice helps a little but not a lot because
to melt 1 kg ice, it only takes about 140 kilojoules of energy compared to 910 kJ required to evaporate the water. So you get 6 times the benefit of the evaporation of water compared to just melt it. No doubt it helps, but do not worry too much about it unless you happen to work for an ice-making business and has plenty of free ice cream available.

Bottom line - I'm glad it does what it must do because it's just me sitting beside my computer. And it is much more affordable for me and much easier on the environment.

KuulAire PACKA50 Portable Evaporative Cooling Unit with 350 Square Foot Cooling Capacity, 750 CFM

I think KA50 doing a good job at what it aims to do. Since I live in Arizona, it's very dry here. I quit using it all year. In the summer of his used to cool the house and in the winter to add moisture to the air side on the outside dry. When output is called the 350 sq ft, they mean it.

Since it has a lot of water, it can be hard to fill, so I use a hose from my laundry sink. If you do not have one, you can use a water fish trap in the opposite direction. There is a meter that tells how much water is in the unit (min - max). It's just a float attached to a piece of plastic to push up the meter. FYI, if the drive is empty or very low, the flow tends to get stuck and end up over the filling of the device, because it will still say my time fully. A simple push on the machine loses float and you're good to go. Something to think about, but would not deter me from buying.

The unit has five wheels on it and go with little effort on tile or carpet. (No complaints here)

Sleep: I can not see myself using it so much. All it does is to switch between low, medium and high fan, and prices can be a bit annoying with varying noise, there is a drastic sound difference between low and high.

Air direction is easy to control. There is a button that allows the system to swing left to right or desktop. The vertical control is manually adjusted by turning the vertical slats up and down in preset positions which they click on. (No complaints here)

Size: Large. By ownership, I was glad of his size. I know that the measurements are stationed, but when you look at it in a store vs. time in his room to change the perspective a lot. Not something that would deter me from buying, just something to think about. Measure of how its once before you buy.

It has a removable filter at the back. Basic construction. Snap off, clean and snap again. (No complaints here)

Hours: again, basic. You have an option for 1-8 hours to drive up an hour at a time.

The device can be used for cooling (water pump) or just as a fan (you guessed it, water pump off).

Has a remote and a cradle to hold it when not in use. (Reduces the change in the distant err)

It has a powerful fan and has a button you can adjust to control how much moisture to add air. My only complaint is that it is a bit on the high side.

All in all, it's a great machine and does what is advertised. If you use it in the same room you sleep in, you may want to use ear plugs, lol. As previously mentioned, it is not exactly the quietest part of the equipment in the house. The best use I'd probably use it when you're at work or have the machine in another room block some of the noise. You watch TV with this device next to you is not exactly an easy task. It is not intended for smaller spaces such as production of this machine is great. At very high volumes. It is more a lounge than a single room or an entire apartment. FYI, if you have high humidity in your area, no evaporative coolers useless. They are designed for dry weather.

SPT SF-608R Portable Evaporative Air Cooler

First and foremost, it is not an air conditioner. If you expect your room to be icy, it is not the product for you. It is a cooler, and it does its job very well. It works by evaporation of water. Try soaking a T-shirt, wring it out and put it to soak for efficacy. It does not work well in humid areas, but it works well where the air is dry.
I am in Southern California, where the humidity is quite variable. I sat on the cooler six or eight feet from my chair, and on the hottest days I'm pretty comfortable.
Advantages:
* It's about 1 / 5 the cost of an air conditioner
* Operating profit cost is a fraction of the cost of air conditioning
* Smart features! (Hours, sleep, etc.)
* Remote control

Cons:
* It is bitterly cold as air conditioning.

Low cost, highly effective in low humidity. Has a strong fan when not using the cooling function. Timer works well. Have an oscillating function, a "sleep mode" and, most importantly: a drain plug, washable filter element and a plastic that can not rust as they made of sheet metal or tin.
It is in the high 90s to the low 100 degrees here in San Fernando Valley in California with low humidity and it is held, which place it is cool enough not to turn on the AC.
There is no air conditioning, but it is low cost [to purchase and run] Alternatively, one can say yet was an "environmentally friendly" way to stay home this summer. But then my friends to talk me out of buying a wringer washing machine, so my opinion is based on my personal preference for simplicity and old-fashioned way of doing things.
Take my review as you wish. It does what it says it will. If you have frequent high humidity, it will not be effective and the company says it was warned. I think there must be a good buy, and go silent too.
