VIVOSUN Electric Mini Dehumidifier, Ultra-Quiet Auto Defrost Dehumidifier with Timer, 2200ML Water Tank and Drain Hose for Basement or Closets, Bedrooms, Showers, and Other Small Rooms

I purchased this dehumidifier for a 4x8x6 tent (also Vivosun). I went with this model for the overall size of the unit. It takes up the least amount of space inside a tent of any other product I have been able to find. So far this dehu has done exactly what I needed. It does shut off when it reaches a specific humidity but does not turn back on when it drops below a specific humidity. I have not used the reservoir tank as it comes with a hose attachment so you never have to empty it.

Ok so working with this item for several months... I find that it does not function very well at all... I have it in a small room, like h3xl4xw2 and it just cant not keep up. That's not the worst.. it shuts off and doesnt come back on.... the fact that it has an led style digital power button,under the lights you cant tell if the unit is on or off... by the time you realize it...your having to vent the hole room, lastly even when it is working I cant tell that it's actually on... the air movement is so weak... I almost feel as it is not working at all... I just bought a manual dehumidifier just because this has caused me all sorts of problems especially with mold. I want to curse this item... I was a fan of vivosun but it feels like all they do is take an item previously made and slap a name on it... as in this is not for a legit grow room... I tried placing in different spot I'm bigger rooms, smaller... it just doesnt seem to do what it suppose to do which is dehumidify... the best use for this thing is as a gauge for humidity because that is the best feature... it reads humidity very well...I have a separate meter for that and this items gauge and my other seem to be on point with each other. But as mentioned dont buy for a tent ... this is awful even in a small tent.

This mini dehumidifier does exactly as it is designed for and well. No issue so far have just been emptying the water tray by hand. By far the quietest dehumidifier I have had. Works for an 9"×7" bedroom on the second floor facing the west side. It how ever was a bit larger then I intend for my space. New tent time!

At first I was a little undecided if I wanted to buy this unit based on all the negative reviews I had read. Most of the people who had bought this unit, had bought this unit to do a job it couldn't handle. This unit was not intended to dehumidify bedrooms and closets or basements. This unit was solely intended to be used in grow tents. This unit performs as it should in the space I have it in which is a 4x4x7 Ac Infinity grow tent. In the instruction manual it's says: When the ambient humidity falls below 60%, the dehumidification unit will not be as powerful and this is to prevent the grow space from becoming too dry. You don't want to dry your plants out you'll kill them. Secondly, it says, when the ambient humidity falls below 15C or 59F or the RH falls below 40% the unit will almost stop extracting moisture from the air. This is exactly what you want in your grow environment. Now, depending on where you live and what your environment is like will determine if this unit will work for you. I'll explain: I live up north in Buffalo, NY during the winter months i'll use a humidifier when the ambient air is too dry and that is usually when the temperature is 0c or 32F now 35F I'll start thinking about dehumidification. However June, July and August my ambient humidity is killer like 80%-95% and above at times so this unit will not perform in a situation like that I'll need a much more powerful unit something that can move 22-50 pints of moisture a day. Or run a AC unit and this unit it draws little power anyway. To sum up this review remember this if you're looking to cool a room or a basement. This is the wrong unit it wasn't designed for that purpose. If that is what you are looking for then buy a dehumidifier that can cover 1500 square feet. This dehumidifier is only for GROW TENTS. I highly recommend this unit it does the job well great product. I hope this review helps who ever is in the market for a unit.

It’s small - very small. Maybe ok for a tiny bathroom or closet. Definitely not for a bedroom. It doesn’t run on a compressor so it’s nice and quiet but that also means that it’s not as strong or at least not nearly as effective as the old school ones with a compressor. It does not seem to work well in areas that have “normal” humidity (ie 60% for us). I like to keep my room a bit drier in the summer - this dehumidifier just won’t do.

It's not bad but could corner the market if it included an onboard humidistat to set a desired humidity level. As it is, you have to run it for a few hours then check to see how it did. So this is not your unit if your goal is accuracy. If that's not important, go for it.

I received my dehumidifier today and it worked for 30-45 minutes then the display went nuts and moving super fast that you couldn’t read anything . No water collected as expected due to not running right. This item is junk. Wouldn’t recommend for anyone. Was using for an indoor tent 3x3x5.

Removed less than 8oz of water over a 2 week period from an area that was 85% humidity. Louder than expected. Does not work below 64° at all. Upon turning it on, gives accurate humidity reading, but then changes rapidly to much lower percentage than actual room humidity (I have 2 other gauges). The humidity sensor is on the output end, so it appears to remove moisture by the number, but its actually just reading the air that it blows out, not in. It does not remove moisture at all when humidity gets below 60%. If you want drier than that, dont buy it.
