Best Value Portable Swamp Coolers to Buy Online

If you want a portable swamp cooler that offers great value for money with effective, easy-to-use cooling capability, here are some low price examples that work well in most dry conditions.

When you’re looking for economical ways to stay cool during the hot season, it’s not much use looking at small air conditioners to solve your problems because no matter how you look at it, air conditioning is expensive to run. The cheaper alternative is to look at evaporative or swamp coolers because they use a mere fraction of the energy (typically 1/20th of the power consumption of AC) and can also be found for a surprisingly affordable price tag at some of the best online stores.

Here’s an image of one of the best portable room cooing devices I’ve ever seen:

But why is the best? What made me decide to feature this model over all the others that are priced at surprisingly low levels? Well, here are a few reasons you might be interested in:

What Makes this Appliance the “Best”?

Take a look at these key features of a simple to use yet powerful and effective cooling unit that is lightweight and portable with no trailing vent hose to worry about:

  • Effective room cooling and humidifying in dry climates
  • Evaporated water cools the atmosphere via powerful fan: oscillating louvers give even distribution
  • 23 feet per second flow for fast cooling
  • Controllable with 3 speeds and 1/2-hour to 7-1/2-hour timer + sleep mode and remote control
  • Unparalleled value for money: low, economical running costs

How Does it Work?

This indoor room cooling unit works by endothermic reaction (which is a reaction that consumes heat), which I’ll explain in every day terms:

The unit sucks room temperature air through a wick that has been saturated with water. As the air flows through the damp wick, some of the moisture evaporates into the room which literally consumes the heat that was in the air.

A nicely chilled breeze is then blown out through the front of the unit, which is a lot cooler than the room’s temperature. That’s what reduces the temperature in the room making it feel comfortable and pleasant to be in.

Note: The unit works best in dry climates (with low average humidity) but it is not so effective in areas that have high average humidity. The reason for this is that the unit utilizes moisture to cool the air and if it is already saturated with moisture, the chill effect is greatly reduced.

On the plus side, since this is not a regular air conditioner with no motorized heat exchange and refrigeration process, it uses much less energy to do its job. That translates into a lot of dollars you save when you choose this kind of device over a traditional aircon unit.

More Choices of Great Value Evaporative Cooling Units

While the example above is in my opinion the best in its price range, there are some other units that come a close second in terms of purchase cost, features and effectiveness when used in the right climate (which is low humidity). Here are some alternative choices that you might be interested in looking at in more detail:

    Can you give me some idea of areas this would be good for.
    What % humidity are we talking about.

      These coolers work best in under 50% humidity. They’ll still work at higher levels but you need to remember to keep a window and a door open to allow air to circulate. I’ve heard of people using them at 80% humidity and still getting cold air, but that’s not the norm.

      It’s surprising how many people buy these coolers thinking they’re AC when they’re not. So they send them back because they didn’t perform like an AC. Or they ran them with all doors and windows closed tight (increasing the humidity inside until they stopped giving out cold air).

      On the flip side I know plenty of people (me included) who use a swamp cooler and get great performance from it. The trick is knowing what it is, how it works and what it can and cannot do. When you use them right, they are pretty amazing yet cost next to nothing to run when compared to AC.

    They work great to cool outdoor areas even in high humidity areas such as the South.
