IMPORTANT!!! DO NOT plug in immediately when you receive it! Mine was delivered laying on its side so you have to sit it up right for 24+ hours before plugging it in. Amazon didn't put it in a box labeled to keep it up right but the original box says "do not lay down on side". I have an air purifier this same brand (KNKA) and now this dehumidifier. I got them because my chinchillas have to stay in cool/dry climates and with them using dust for dust baths and their fur shedding, these products have helped tremendously. This dehumidifier is half the size of my previous one but works better. It is so cute and isn't an eyesore like a lot of them are. It has multiple settings, dehumidify, dry, and continous, high/low fan speed, and/or you can set it to the humidity you want your room to be. Chinchillas do best in humidity below 40-50% and with my previous dehumidifier I had to set it on continuous and it could barely keep it below 45%. With this one I put it on the same setting and the few days I've used it so far it has kept my chin room 29-32% without a problem. It is a lot more quiet than my last one too. I really like this brand because of the price but mostly because of how well the products are made and how well they work. They have been packaged well and I don't think it was the company's fault it was delivered laying down because on the side of the original box says not to but Amazon put it in an unmarked box so the delivery people didn't know it was supposed to stay upright. Overall I believe it is well worth the price and in my opinion, works better than others its size.

Excellent Purchase - Quiet and Effective We purchased the KNKA 2500 Sq. Ft. Dehumidifier to improve comfort for our baby grandson, and it turned out to be a very good choice. The unit works quietly, and most importantly, it quickly reduces humidity to the level recommended by pediatricians. In our hot and humid climate, this makes a big difference. One of the best features is the continuous drainage option using the included flexible hose. This means we do not have to keep emptying the water tank, which is always inconvenient. It is also easy to move from room to room. The unit is not too heavy, and the leather handle on top provides a comfortable and secure grip. Overall, it is a quiet, efficient, and low-maintenance dehumidifier. This is exactly the kind of appliance we need in our home. A successful purchase - I highly recommend it.

My husband and I bought this dehumidifier specifically for a bathroom with poor circulation—it only has a small window and no vent—and it has made a huge difference. Even with a small plug-in fan, we were starting to notice slight mold on the ceiling, and this completely solved the problem. This dehumidifier works incredibly well. It’s honestly amazing how quickly the tank fills up, which really shows how much moisture it’s pulling from the air. Since using it, the bathroom dries out much faster and feels noticeably fresher. It’s easy to use, fairly quiet, and I appreciate that it’s compact and not ugly or bulky like some other units. The design blends in just fine. The wheels are a big plus—super easy to move around when needed. Overall, this has been a fantastic purchase and exactly what we needed for a high-humidity space. Highly recommend if you’re dealing with moisture, mold, or poor ventilation.

Giving this 4 stars - it's honestly a great machine, just not for 2500 sq ft like it says. I bought this hoping it would cover my whole floor, but that didn't work out. However, I moved it to my bedroom and it's been perfect there. Works great in smaller rooms - I'd say anything under 800-1000 sq ft and you're good. What I really like about it: The design looks nice and doesn't feel cheap. It's quiet enough that I keep it running while I sleep. The handle is actually practical and makes it easy to carry from room to room. The water level window is super clear so you always know what's going on. All the controls are straightforward, no confusing settings. My bedroom humidity is totally under control now and the unit just does its job without being annoying. The 2500 sq ft claim is definitely off, but for the right sized room this thing works really well. If you need something for a bedroom, office, or smaller basement space, I'd recommend it. Just manage your expectations on coverage and you'll be happy with it.

I couldn’t be happier with this dehumidifier! From the moment I turned it on, I noticed a difference in the air quality in my home. It works quietly and efficiently, pulling moisture out of the air much faster than I expected. Within just a day or two, the musty smell in my basement was completely gone, and the air felt noticeably fresher and more comfortable. One of the things I appreciate most is how easy it is to use. The controls are simple and intuitive, and the water tank is easy to remove and empty. I also love that it automatically shuts off when the tank is full, which gives me peace of mind if I’m not nearby. Another huge plus is how quiet it is. Even when it’s running, it’s barely noticeable, which makes it perfect for bedrooms, basements, or living areas. It’s powerful without being disruptive. Overall, this dehumidifier has exceeded my expectations. It’s reliable, efficient, and has made a big difference in the comfort of my home. If you’re dealing with humidity, dampness, or musty odors, I highly recommend this unit—it’s absolutely worth it!

I live in the Pacific NW, where it rains almost constantly during the winter months, so I really needed this quiet, powerful, whole-house dehumidifier that is only about the size of my carry-on luggage. Until I realized how powerful it is, I first used it inside a large travel trailer - but I soon discovered that was overkill; the best way to use it is inside your house. If possible, place it on a countertop near a sink, or on a bathroom floor near a walk-in shower drain, and run it in the CONT mode. It wrings a lot of water out of the air, so keep it near a drain and connect the included hose, because it is capable of filling the onboard tank in about 4 hours if the humidity is high - and it will keep shutting itself off with a full tank unless the drain hose is used. It has a quiet mode that slows the fan considerably, if you need to use it near a bedroom. It's heavier than I expected, but it's on wheels, and it has a very high quality handle. I'm glad to have this dehumidifier in my home, because the risk of mildew or mold is much lower now, and my family feels more comfortable. I highly recommend it.

Compact and power efficient dehumidifier. Got this to use in my basement. My mil stays on the lower floor of the house, but doesnt like to run the ac (she's 88 and likes it warm). Without the ac running, it can get a little damp in the summer (i live in the south). Got this to help keep humidity in check. So far, running well. It's been raining all weekend and it is holding close to the 50% setting i put it on. It uses about 100-200 watts, so not bad on electricity. It is also very quiet. It is a nice looking unit, so no issues having it out where people can see it. It does come with a hose you can run to a drain (then no emptying drain tanks). I also have a knka air filter and have good experience with it so seems like a solid brand.

This dehumidifier has some significant advantages. First, it's quiet! 48 db on low and 52 db on high (measured with NIOSH sound level monitoring cell phone app). Better than others, and good if you have a baby sleeping in the room. The reservoir is large, and it definitely takes the water out of the air - about 20% full after running on high for 12 hours in a large room that was at 64% humidity. The design is sleek and modern, accentuated with the faux leather handle. So it blends in well with modern home furnishing design. It's also assembled well. Even though it's mostly plastic, it feels solid and the parts fit together cleanly, without gaps (where there are removable parts, like the reservoir). What else should you know? If the room is extremely large, it may not make a material change in the room’s humidity level - even if it pulls a significant amount of water out of the air. So consider a more powerful option if you have a very large area to dehumidify - or buy two! The control panel buttons are simple. There are only six of them, but you might need to reference the instructions for some of the functions. For this, you can download an e-manual from the support website. Finally, I did not find a way to turn off the LED light, which is no problem for me, but may be an issue if someone is trying to sleep in a dark room where the machine is on. All in all, it works well.
