Dehumidifiers, JREAWD Portable Small Dehumidifiers for 320 Sq.Ft with Defrost Protection LED Light 40oz(1200ml) Ultra Quiet Dehumidifiers for Home Bedroom Bathroom Kitchen Closet Office RV

I've been using my dehumidifier for a full day and a couple of hours. I placed it in my bedroom. I'm surprised at how much water has been collected so far. I can definitely tell a difference in the air. The dehumidifier does make a little noise; however, it isn't obnoxiously loud.

I bought this item for my travel trailer and it works great! I'm currently on the west coast and very wet, this device is doing its job wonderfully. I would recommend for any small area and it even has night lights.

I got this little humidifier for my kids room and it stopped working after 2 months. It would fill up with water so it was doing the job, but after 2 months it stopped working ☹️

I've only had it 1 week and it's better than any other small ones I've purchased previously (mostly the 16 or 17 oz capacity ones). I live on the coast so humidity is a problem here. Worth every penny.

The square footage of my office (with the door closed) is appropriate for this model but I ran it for 3 days and it barely took any water out of the air. There was less than 1/2" in the canister and the humidity never went down. I'd give it zero stars if I could. The only upside is the pretty lights and the fact that people mistake it for a coffee maker.

I recently picked up several small room-based dehumidifiers for my home to test out. This is the smallest and least feature-rich of the bunch, but it actually works reasonably well for what it is.Now, your home air conditioner, your kitchen refrigerator, etc, use coolant, in a "fluid phase change loop" refrigeration system. Whole-house dehumidifiers also use this sort of system, but they don't permanently remove the heat... and dump it outside the area it's cooling... rather, they remove the heat temporarily, just to allow water vapor in the air to condense, then return that heat to the air again. This is a very effective cooling methodology, but it's not inexpensive, nor is it "trouble-free."That's where these devices come in. Instead of moving fluid, expanding and compressing it, and transferring heat into and out of the fluid, these use a "solid state" technology known as the "Peltier Effect." Discovered by the French physicist Jean-Charles-Athanase Peltier, the Peltier effect is the cooling of one junction and the heating of the other when electric current is maintained in a circuit of material consisting of two dissimilar conductors (the effect is even stronger in circuits containing dissimilar semiconductors).In practical terms, Peltier plates are found in little table-top beverage refrigerators, and in these. At one point, they were used to do electronics cooling, but modern electronics dissipate more power than the Peltier effect can manage, so you don't see this used much anymore.When you get this device, and plug it in, it will seem to not be doing much at first. It'll light up, and air will move through it, but no liquid will drip into the water tank. This is because it takes time for the plate to get cold enough to start condensing water out of the air. Once it's cold enough, and assuming that your air is humid, you'll start seeing droplets of water drip into the tank.It will work to remove excess moisture from the air, but it does so at a rate of a few droplets per minute at peak output. Given that more than that enters your house through window and door gaps, chimneys and vent fan exhausts, and so on, you should not expect little devices like this to handle much more than a small room (with limited airflow through).This device lack the "extras" some other units have... there's no room temperature or room humidity display, there's no "automation" (where the unit turns on or off based upon the room humidity). It's simply "on" or "off."This unit does have the most obviously visible TANK of any unit I've tested out, and it's the easiest to remove and replace, as well. So, putting this someplace very visible and often visited... say, on your bathroom counter... is a good choice.Most of these little Peltier-effect dehumidifiers have "lighting effects," but in this case, it's actually kind of useful, as a "bathroom nightlight." So, while my other units have the light turned off, I'm leaving this one on.It's a solid piece, but don't expect more from it than it is able to provide. It's a little supplement. You still need whole-house dehumidification, if you really want to manage moisture in your home.

I like the fact I can move them anywhere in the room and they work. Bought 2 of them, one for each bedroom upstairs.

This works great for such a small unit. I notice a big change in the room I have it in.
