IVADM45

I live in Arkansas in an old Victorian home that was converted into small apartments. The weather in Arkansas can get brutally humid and the air in my bedroom has always felt heavy and stale (a fan didn't help at all). After several years of living there, I started noticing mildew spots that were concerning me. Cleaning them up was only going to be a temporary solution so I did some research and purchased the Ivation dehumidifier, which was listed on several reviews as being one of the best and was definitely the best buy for the money. I really thought I needed a bigger one but, frankly, I wasn't about to pay the high prices. I figured whatever this dehumidifier could do was better than nothing. Needless to say, I didn't have real high expectations.The first thing I noticed was that the look of it is pretty sleek and it turned out to be the perfect size for the spot I needed it in. I didn't really notice any difference in the air quality until the next morning... but, Wow... what a difference. The soft hum of the machine lulled me to sleep and for the first time in a long time I slept like a rock. The air literally felt lighter that next morning (even my dog slept in). The dishrag smell was gone, too. I couldn't believe it. I've had it for about a month now and I absolutely love it. I just keep it on because it turns itself off once it reaches the relative humidity I set it for (I'm originally from California, so I keep mine set to 45% RH).It may be important to note that it doesn't cool down the room any (but I never expected it to). It does, however, makes the heat bearable now that I'm not wearing the weather.I honestly can't imagine living without it now.

I've used this in camper while it is in storage. Has worked great for that and only uses like $5 in electricity running non-stop in a month. Used it for two summers now. Removes about a quart of water a week.Where people are mistaken about this unit is using it in large rooms are rooms not well sealed. Its going to be useless in a shed that is full of air gaps. It is going to be useless in a room that is constantly having the door/windows opened.For reference, a central air conditioner removes GALLONS of water per day out of your average southern home. This unit is only capable of maybe a cup per day depending on the conditions. If your central A/C isn't removing enough moisture then this dehumidifier isn't going to fix that problem with its cup per day of capability.

They're not kidding about 100 sq ft maximum. In this size room, starting at 60% RH, the unit condensed a cup of water every 2-3 days, lowering the RH by 2 percent compared to similar rooms in the house. So 58% instead of 60%. Not much different. The humidity control feature works, although the hygrometer reads 5 to 10% lower than other hygrometers. So to kick on at 50%, you need to set it for 40%. At a distance of 1 m, the fan noise is 46 dB (A-weighted). That's quieter than a compressor unit, but it's loud for such a small fan. Not adequate for my application, but maybe for a closet or for much higher starting humidity level.

Quite honestly, I am not impressed.I have an 12x13x8 (1240 ft^3) work room where I keep my 3D hydrophilic printing filaments.I originally purchased the Ivation IVADM45 (which is advertised to handle a 2200 ft^3 room) to keep the RH at or below 40%. It didn’t perform the expected task. In fact, it only condenses about 4oz-6oz of water per day - not the advertised 20oz. So, I added the Ivation GDM30 (also advertised to handle a 2200 ft^3 room). I expected, between the two at each end of the room, that my goal could be achieved with the two running. They didn’t seem to be performing as advertised so I purchased an AcuRite 00613 indoor Humidity Monitor specifically for that room. I checked it against another hygrometer in the house and they were in agreement so, I am assuming the AcuRite 00613 indoor Humidity Monitor works fine. The end result is that they are not performing as expected. I believe I would have been in a better position had I used the $200 spent on the Ivation equipment on a bigger typical dehumidifier.I have had both the Ivation IVADM45 and GDM30 running since I received them and have yet to have either of the reservoirs reach half full or have to empty them. I received the Ivation IVADM45 on Feb 27th and the Ivation GDM30 March 6th. The room itself is fairly hermetically closed with one new window - double pane, inert gas, uv protection - with a closed blind. The door is a basic room door that I have fortified with weather stripping keeping it closed as often as possible. I have remote cameras in the room so I do not need to go in and out as often.I complained and promptly, and courteously, received two brand new units to replace the others that apparently were not working. The new units had the same result. In all the time I have had these (3 full months now) they never performed better than a 7-10 percent drop from the rest of the house with ALL FOUR running. Definitely not suitable for my needs. I plan on getting rid of these and getting the expensive unit I should have in the first place!!!
