I like it alot!
Color: White Size: MAX 80 Pints
I like it a lot. I had no idea there was so much moisture in our house! The only problem that I have found with this unit is that when you go to empty the water water comes out of all sides when you’re pouring it, and therefore there is always a spill, no matter how hard you try not to spill the water when you’re dumping it because it is a large reservoir. Now that being said, I’m always glad to be dumping it because I’m glad that much moisture is getting out of my home. ... show more

Reliable Large‑Space Dehumidifier, Easy to Maintain
Color: White Size: MAX 80 Pints
If you need a dehumidifier for big rooms or basements, look no further. This 5500 sq.ft 80‑pint model is powerful and dependable. The drain hose makes continuous use convenient, no frequent tank emptying. Smart humidity control keeps air comfortable without constant manual adjustments. Sleep mode is perfect for nighttime in bedrooms. Energy Star certified for good energy efficiency. The unit is sturdy, easy to clean, and delivers consistent results day after day. ... show more

Inadequate for coverage of square feet advertised.
Color: White Size: MAX 80 Pints
The unit has one of the smallest holding tanks for water removed from the air I have ever encountered. The autonomic shutoff mechanism for when the tank fills up does not work. This seems to be a design problem more than a failure to my individual unit. The shape of the tank which wraps around the core of the unit is awkward and easy to mishandle. I would advise using it only with the drain hose attached, which is too short anyway. Struggles to reduce humidity in a less than 1000 sq foot apartment, much less a 5500 sq ft one. Needs to be emptied about every eight hours minimally if hose drainage not used. Unit has to be elevated to properly function in that configuration as well. Optional foldable overflow tank was a joke as well. ... show more

Works like a charm!!!
Color: White Size: MAX 80 Pints
This dehumidifier has been a game changer for our basement. We have an unfinished basement in our new home and it always felt so damp. Then we noticed a few things starting to get moldy so we started looking for a dehumidifier. After looking at dozens we settled on this one and boy are we happy. It made a difference right away. When we first turned it on, humidity was reading 64 and within 24 hours it was down into the mid 50’s and it consistently got drier and drier with each passing day. We got the external bucket so that is was easier to empty and we absolutely love that and highly recommend it. After a couple of weeks we decided to add a second unit and now our 1800 SF basement has a humidity reading of 34-35. No more mold. We are extremely happy with these machines. ... show more

Works like a charm
Color: White Size: MAX 80 Pints
This dehumidifier is fantastic, I run it on auto in my bedroom due to some serious moisture and odor problems from my upstairs neighbors window a/c unit. This worked immediately on not only the moisture but also the odor, it’s completely gone. I have zero complaints and highly recommend, especially since I was also able to buy it on a payment plan. ... show more

Heavy-Duty Dehumidifier for Serious Moisture Control
Color: White Size: MAX 80 Pints
Installed this KNKA 80-pint dehumidifier in my basement and it's tackled moisture problems that smaller units couldn't handle. The 4500 square-foot capacity means it works across large spaces without struggling; humidity levels drop noticeably within hours of running. The 80 pint-per-day extraction rate is legitimate—you're actually removing significant moisture instead of just running a fan, which matters in damp basements or high-humidity climates. The included drain hose eliminates constant bucket emptying; you can run it continuously into a floor drain or condensation line without intervention. The Energy Star rating keeps electricity costs reasonable despite the heavy-duty performance; efficiency doesn't sacrifice power. The smart humidity control automatically adjusts operation based on ambient moisture levels, so you're not running it full-blast unnecessarily. The sleep mode is thoughtful—reduces noise during nighttime operation without completely shutting down moisture removal. Works equally well for basements, large bedrooms, bathrooms, or any room where humidity is a persistent problem. Build quality is solid and the controls are intuitive without requiring a manual constantly. Essential for anyone dealing with dampness, mold concerns, or general moisture problems in large living spaces. ... show more

This dehumidifier does the job!
Color: White Size: MAX 80 Pints
Our basement does not feel like a swamp anymore! Running this unit keeps the humidity in the basement in the low 50s compared with the high 80s where it was. It worked quickly. I have to empty it every 24-36 hours, but the bin when full is not too heavy. You have to remove the bin carefully when it is completely full. But I got the hang of it and can empty it easily without spilling now. It is pretty quiet and easy to set up and use. ... show more

Good Choice!
Color: White Size: MAX 80 Pints
When our old dehumidifier went to appliance heaven we had to make a quick choice and it appears, at least as of today, that we made a good choice! We haven't had this dehumidifier very long yet, but it was easy to set up and so far it has been trouble free. It runs so quietly that we don't even know it's ON unless we actually go down stairs to check on it. It does a good job of removing moisture from our basement which we drain directly into a floor drain so bucket capacity really doesn't apply for us. ... show more
