I’ve been using the SEAVON 21 Pint Dehumidifier for a bit now, and honestly, it’s been great. It’s small, lightweight, and super simple to set up—basically plug it in, pick your setting, and let it do its thing. It pulls a surprising amount of moisture out of the air. Within a few hours you can actually feel the room is less stuffy, and it helps get rid of that damp, musty smell. It’s also pretty quiet, which I appreciate. I can run it at night or while watching TV without it being annoying. The only downside is the water tank isn’t huge, so if you’re dealing with a really humid room, you’ll be emptying it more often. But if you hook up the drain hose, it’s not a big deal. Also, this isn’t a big heavy-duty unit—better for bedrooms, bathrooms, or small basements, not huge spaces. Overall, it’s a solid little dehumidifier for the price. Easy to use, works well, and keeps the air feeling a lot more comfortable.

First impression is that it was a lot heavier than I imagined. But that’s a good thing. It means it’s powerful! Medium sized dehumidifier. Not like the smaller counter top ones but not a huge large basement type one. Perfect for what I needed it for. I went thru two other smaller ones and they just weren’t powerful enough for the conditions it would be in and what I’d need it to do. I have a small pop up greenhouse and adding a hot sink to it caused the humidity in it to skyrocket to 90%-95% - it’s a 5 gallon bucket with an immersion heater that keeps the water at 110 degrees to release heat into the greenhouse along with a smaller regular heater. Didn’t think it thru and next thing ya kno the humidity levels in there shot up! The first two dehumidifiers just weren’t powerful enough to get it from 90-95% down to 75% tops. It’s not the fault of the smaller Dehumidifiers - they just weren’t strong enough to deal with the high humidity in there and the constant humidity that was continuously being added into the atmosphere from the hot sink. I decided to get this medium sized one to see if it would work better. I don’t have the data quite yet but based on the look, size, and feel - I’m sure this should do the trick! I also like how it has a clothes drying function. I might even end up using it outside of my greenhouse in the winter and use it to dry things in the summertime! I like the drain pipe so I don’t have to constantly empty a container and I can even recycle the water and put it back into the 5 gallon bucket hot sink to be re-used! Ill try and update this once I have some hard data but keep in mind I am using it in extreme conditions in my greenhouse. I’m sure the smaller ones that I got were fine too - they just didn’t suit my specific needs for the extreme conditions. Since it’s so heavy the wheels on the bottom add a nice touch! Edit: it’s been running for several hours now and even tho it’s rainy outside and more moist - this has kept the humidity down in the greenhouse to exactly where I want it to be - as I expected. I have it set for 70% and right now, my temp gauge and hydrometer is recording 74% and it’s kept the humidity down to the 70% range, which is what I wanted. Even if the devices hydrometer reads 70% right now it’s still all within the range I wanted it to be which was above 60% but below 80% and definitely no more than 85%

I purchased this Seavon AS280-W 21 pint dehumidifier at the suggestion of a friend who used one in the past and had a good experience with it. This instructions were very easy to follow and after plugging it in I noticed that its extremely quiet. It seems to be working well in my basement which is about 1500 square feet. It reduced the humidity significantly within the first week. It comes with a plastic hose if you choose to empty the water into a pump pump or you have the option to empty the water receptacle when it becomes full. A bright red light will tell you when it is full. It is easy to remove the water receptacle from the front and empty it. I would absolutely recommend this model to anyone needing a dehumidifier.

UPDATE: Since posting my review, the company reached out and offered a replacement. I am awaiting the replacement but in the meanwhile have updated to 4 stars. I will run the new unit and see if it lasts this time! Worked great for the first summer. The 2nd not so much. Immediately would run but not work. Instead of draining into the internal container, it just freezes up behind the air intake. I was initially impressed but do not buy if you want something that lasts. Used in a controlled, finished basement. Never abused.

I’ve been battling dampness and that musty smell in my basement for years, and this 500 sq.ft dehumidifier has been a total game changer! It’s compact, lightweight, and surprisingly powerful for its size. Within just a few hours of turning it on, I could already feel the difference — the air felt fresher, and the humidity level dropped noticeably. The water tank is easy to remove and empty, and I love that it shuts off automatically when full. It’s also very quiet — just a low hum that’s easy to forget about, even when I’m working nearby. The sleek design fits nicely in the corner and doesn’t take up much space. I’ve been running it daily for a few weeks now, and my basement feels dry and comfortable for the first time ever. No more condensation on the windows or that “wet basement” smell. Totally worth every penny! Highly recommend for anyone dealing with moisture in small to medium spaces — this little machine really delivers!

I've been running this dehumidifier in our little travel trailer for several days now and so far I'm thoroughly impressed with how much water it can pull out of the air given its small size and low energy consumption. This seems like about the perfect little unit for a smaller RV/camper/travel trailer. I don't have solar panels on my trailer just yet, but this would be a great addition to a solar setup since even a small to moderate system should easily be able to handle this thing running around the clock. It would be perfect for me since I don't have an outlet where I store my trailer and the humidity here can get fairly high. A couple other things that impressed me about this dehumidifier are its quiet operation and solid build quality. Time will tell how well it'll hold up to frequent use, but so far it seems to be of a higher quality than some of the other units I've owned in the past. If I had to come up with any 'desired changes' (I won't call them 'problems' because I'm being nit-picky here), it would be to add the option of turning off the light on the front of the unit (it's easy enough to throw a piece of tape over it, though), and also add the option to silence the beeps when pressing the buttons...again, nit-picking, but it would be nice to have the option. Overall. I'd consider this a solid little performer!

Amazing Dehumidifier, but not for 1500 square feet. This is the second of these dehumidifiers I have bought. The first was for my bathroom and it works SO well. So, I bought a second for my living room which has some humidity problems. Now, my total house is 1600 square feet and I keep the bathroom and bedroom doors closed, so there’s no reason a dehumidifier claiming to work on 1500 square feet shouldn’t work on a less than 1000 square foot living room? But it doesn’t. It can’t get it below 75% humidity which is not at all what I was hoping considering it regularly maintains 40% in my bathroom. I guess just be mindful that this is only going to work in a small, confined space.

This works well for a garage. I use it draining into a condensate pump which allows the water collected to be sent outside. As long as all of the instructions are followed, this will work well. I had an issue and the company responded very well and resolved my issue. The unit is not heavy but if you have to drain the tank depending on how much humidity is collected, you may need to drain it once a day like I had to do before getting the condensate pump. The noise level is very low as I barely notice it's even on without any other sound. My two-car garage at about 600 square feet is usually around 65% humidity in the state of Georgia but with this, it's consistently kept at about 45% during spring and summer months. As many of you may know, 60% or higher is what mold likes. This unit is good for mold prevention. There are two different speed settings for the fan. I keep it on high because the power usage isn't bad. It's kind of like having half the power of a laptop running. I like the design of the unit but recommend a condensate pump if the water needs to flow upwards at all from where the dehumidifier is placed without tank drain. Otherwise the tank would need to be drained regularly. The value is worth it and pays for itself over time to keep mold and possibly any bugs away that like a high humidity environment. I have a second one of these in my bathroom which drains into the sink. That one helps with humidity in the bathroom as well as the bedrooms near it.
