  • Sleek and quiet, love it
Size: 145 Pints Style: Fine
The unit has a solid weight to it, but the handles make it easy to move around. While it's on the pricier side, it feels very sturdy, operates quietly, and looks sleek. It's comparable in size to most dehumidifiers and effectively removes water even in high humidity. I appreciate that I don't have to empty a bucket—the water drains automatically by gravity as long as the unit is placed higher than the drain. Great purchase! ... show more

  • Comprehensive Review: Moiswell 145 Pint Commercial Dehumidifier ... It's a Beast!
Size: 145 Pints Style: Fine
After dealing with persistent humidity issues in our crawl space, we decided it was time for an upgrade. Our previous dehumidifier, while functional for smaller spaces, proved inadequate for the demands of our larger, more humid crawl space. After some research, we opted for the Moiswell 145 Pint Commercial Dehumidifier, and it has been a game-changer. Installation & Initial Impressions Installing the Moiswell dehumidifier was straightforward. We mounted it securely onto the joists, a placement that not only keeps the unit out of the way but also allows for optimal airflow. The unit’s design is robust and feels like it’s built to last, which was one of the first things we noticed upon unpacking it. Once installed, we turned the unit on and monitored the humidity levels closely. At 10:30 AM, the humidity was a concerning 89%, which had been typical of our crawl space, contributing to issues like musty odors and potential mold growth. By 8 PM the same day, the Moiswell had already brought the humidity down to 64%, and by the following day at noon, it had further decreased to 59%. The rapid reduction in humidity was impressive and far exceeded our expectations based on past experiences with other dehumidifiers. Performance & Efficiency We set the target humidity level to 55%, and the Moiswell unit has been working diligently to maintain this level. The built-in hygrometer appears accurate and responsive, adjusting the unit's operation as needed to maintain the set humidity. The continuous drainage option is particularly convenient; with the drain hose attached, the unit consistently removes moisture from the air without the need for manual emptying. This feature is crucial for a space like ours, where high humidity is a constant issue. Noise Level One of our biggest concerns with a commercial-grade dehumidifier was noise. Given its powerful performance, we were prepared to tolerate some level of noise. However, we were pleasantly surprised to find that the Moiswell runs incredibly quietly. It’s so unobtrusive that we often forget it’s even on. This low noise level is a significant advantage, especially for those who have the unit installed in areas close to living spaces. Overall Satisfaction & Recommendation After using the Moiswell 145 Pint Commercial Dehumidifier for several weeks, we can confidently say that it has exceeded our expectations in every aspect. The humidity levels in our crawl space are now consistently within our desired range, and the air feels noticeably drier and fresher. The peace of mind that comes from knowing our space is protected from excess moisture is invaluable. In summary, if you’re dealing with a similar situation where humidity control is critical, the Moiswell 145 Pint Commercial Dehumidifier is a top-notch solution. It’s effective, efficient, and quiet, making it an excellent choice for both residential and commercial applications. We are extremely satisfied with its performance to date and feel that it fully deserves a 5-star rating. ... show more

  • A Lifesaver for Creekside Living! Awesome Machine replacing my old one!
Size: 145 Pints Style: Fine
Living near a creek is beautiful, but it comes with constant humidity battles, especially in the basement. This dehumidifier has been a total "lifesaver"! It pulls an impressive amount of moisture out of the air and keeps our finished basement to keep it dry and musty-smell free. It is amazing ! I couldn't believe it can draw out 85% of the humidity, and bring it down as low as 15%. Wow! The one I had running for 25 years ( that this one replaces) was larger, noisy and a big electricity draw. Not this one. It's quiet, smooth running. I love that it’s compact enough to fit in tight spots, but powerful enough to handle serious dampness. The drain hose setup makes it hassle-free, and the auto defrost and memory restart features mean I can just set it and forget it, even during storms or power flickers. If your home is near water or deals with seasonal dampness, this is built for tough jobs and absolutely worth every penny ... show more

  • Great so far
Size: 145 Pints Style: Fine
So I had this over 30 days now. It runs almost continuously. As a matter of fact, I only turn it off for cleaning. Highly effective. Seems to be energy efficient. I truly believe that it saves on my energy bill. I’m using this in my basement as I am remodeling. It helps keep the moisture levels down and helps drywall compound setup quicker allowing for better productivity. I took away 1 star only for the fact that it seems to struggles bringing the moisture level below 30 percent even though my basement area is under 1000 square feet…and maybe I am asking for a bit too much. I am very happy with how it works and the value it brings. I purchased it in the winter but I am very confident that it will bring great benefits to all seasons of use. It is quite, effective and efficient. ... show more

  • Nice 👍
Size: 145 Pints Style: Fine
So far so good ! This unit is super quiet and does what’s its supposed to! I own many buildings , garages and houses. I personally currently own 2 Santa fe commercial dehumidifiers and this Moiswell basement type dehumidifiers and several smaller in home type units , comfort for me is a must ! It’s very humid in TN ! Me and my family build large custom homes and small commercial projects in the Knox, Gatlinburg ,Blount , Sevier co. TN area . We use many of the Santa Fe commercial units in the homes we build in crawl spaces but there almost 3 times the price of the Moiswell unit ( for me and my team this is kind of a test to see how long this unit works ) . I’m impressed at this time , but time will tell! I’d say give it a try based on what I’ve seen at this point . It’s quiet , I love the detailed controls on the side and it looks nice also ! ( not that looks mean anything for something like this ) it also seams very energy efficient. This unit is in a very upscale garage with a lot of very nice tools and automobiles. So dry , nice smelling , mold and mildew prevention is a must . The size of the unit is not bad at all . I’d say it’s good value for the price ! I have this unit hard piped outside so there are no leaks at all . 👍👍 ... show more
