    Oh yeah this isn't plastic crap…

    Not worth it for a 5V USB fan blowing some air through a wet filter. Just raises humidity, with little cooling effect.

    • Like every tool, its how you use it that determines how useful it is.

      If used for cooling in a closed room, then these are of little use. But if you use them in addition to an air conditioner, they work quite well.
      AC's suck humidity out of the room, and these put it back. You can also use them in winter, because heating the air drops the relative humidity as well, so it serves to balance it out there as well.

      However they're very simple devices, basically just a computer fan and a filter. They sell them on ebay for $15 posted last time I checked.

        AC's suck humidity out of the room,

        Which, in most cases, is exactly what you want.

        It's the humidity that makes a hot day unbearable.

  • Just a note - this will do SFA in a high humidity environment. Measure your RH before you go buying one.

    • What about using metho instead of water for a cooling effect in higher humidity??

    • Just check summer humidity for your location online

      • Yeah no, the outside humidity can be totally different to the inside humidity, if you want a remotely accurate reading you need to get it from inside the place you are wanting to cool.

        • Accurate humidity figures aren't necessary to work out if evaporative cooling will be useful for your location. Average weather records are an easy place to start.

          Where I am with hot wet summers, (outside) average summer humidity is 69 - 75% & at times much higher. Indoor readings haven't been much different. So evaporative cooling is useless with humidity that high.

          Had tried a powerful mains evaporative cooler I was given - failed, used it as a fan.

          • @INFIDEL:

            Accurate humidity figures aren't necessary to work out if evaporative cooling will be useful for your location.

            I am actively disagreeing with this point, the inside humidity of a room can vary greatly to the humidity of the environment outside. There are lots of variables to take into account, it shouldn't need to be said but just because you haven't seen much variation in your specific circumstance that does not make it the rule for everyone else. You are welcome to take the gamble but I am giving people actual information that is important to them making a decision on this product.

    I love it and purchased second one, (WA) Thanks!

  • the world needs more landfill i heard

  • I’ve had one of these for a few years as my desk fan. It works pretty well, usually dropping the air temperature from the front by 6-8°.

    Any evaporative cooler will work better when the air is dryer. I find mine works well whenever the humidity is below 40% - anything higher and it just feels damp instead of refreshing.

    You do need to change the filter every so often (I find once a year before summer starts is fine.

    The build is pretty simple. But you don’t want a lot of unnecessary complexity.

    I paid a couple of hundred when I for mine and I'm still pretty happy with it. Definitely worth 70 if you're looking for something like this.

    • Wouldn't recommend.
      Much more powerful & effective mains powered evaporate coolers are often sold around this price when on sale

      There are different summer conditions around Australia.
      Some areas are hot & dry (especially arid areas - best suited to evaporate cooling, to a lesser extent Mediterranean climate areas of Melbourne & Adelaide)
      Many others are hot & extremely humid (eg Northern coastal areas - don't add extra humidity with these!).

      Where I am in Brisbane, average summer humidity is 69 - 75% & at times much higher. Making evaporate coolers useless. Often a room smells musty & damp using them.

      People here realised how useless they are & throw them out. Used to pick up mains powered evaporate coolers with powerful fans. So I converted them to operate as great free fans.
