145 Pint Commercial Dehumidifier with Drain Hose for Crawl Spaces, Basements, Industry Water Damage Unit, Large Capacity, Compact, Portable, Auto Defrost, Memory Starting

Amazing machine!
Picked up the Moiswell Defender M145 and it’s honestly been a game changer. Super easy to set up, way quieter than I thought it would be, and it pulls moisture fast. The air in my place feels cleaner and less sticky within a day. Solid build, great performance, and worth every penny. Would definitely buy again.

Excellent dehumidifier (so far). UPDATE – expensive to run!
UPDATE 08/21/25After running this dehumidifier for a full month, we received our first electric bill. To my surprise our bill was a good 25% higher than “normal” for this time of year! 25% is huge! In fact, it was the highest we had ever had in the past decade while owning this house! In addition, for 2 weeks of the month, our temps and humidity were actually significantly lower than average. Therefore, I expected the impact of this unit to have a minimal effect on the power bill! During this time, nothing else was different in our electricity usage other than we were using this dehumidifier, so I am confident the increase was due to running this unit. It did (does) keep the humidity level at the 50% set point, but it seemed to run almost constantly. In order to try to lower our costs, I have increased the humidity level set point 5% to 55%. We have noticed that the unit now cycles on and off more frequently, and we are hopeful this will lower our monthly cost. How much remains to be seen. Just be aware you may have significantly higher electrical costs while using this dehumidifier.ORIGINAL REVIEW:We live in an extremely humid area. We have used standard consumer type dehumidifiers in the past, but they always seem to break down within 3-5 years. We got tired of replacing them, so decided to try something more expensive that is designed for more heavy duty use. Since this is designed for crawl spaces, we thought this might be a good choice for the inside of our home.While this does not affect the rating for this unit, I do have to mention that delivery was terrible. This is very heavy, and I heard and felt the “thump” when it hit the porch. Looking at my Ring doorbell, I saw they basically dropped it onto the porch. Not only that, it was upside down, despite the warnings on the box to keep it upright! Luckily, the unit does not seem to have suffered any ill effects from the abuse it took during shipping/delivery.The first thing I did was to turn the unit upright, and allow it to sit for 24 hours to let the Freon settle. Failure to do so can introduce air bubbles into the line which can cause problems with the compressor. Similar to an air bubble in a vein when it gets to the heart.I made sure to message the seller/manufacturer about the delivery, and they sent me specific instructions about startup to insure there were no issues. After installing the drain hose, I plugged it in, and set the humidity at 20%. This caused the unit to run continuously so we could test it was working properly. At the time it was started, the room temp was 78° at 61% humidity. It took around 1/2 an hour for us to see water start to trickle from the drain hose. 6 hours later, the humidity was at 53%, and got stuck there for the next 2 days. When the humidity finally hit our preferred level at 50%, we changed the set point to 47%. That has been keeping an approx. 1800 sq. ft. space at an average of 50% for almost 2 weeks now.Be advised, this unit has no collection bucket, or pump. It has a gravity drain only, so you need to elevate the unit at least a few inches off the ground, and run the hose to a floor drain or outside (or external pump if you have one ie. sump pump). The hose they provide is quite long, but can be cut to length. However, it is on the thin side, and can be crushed easily. This is my only negative with this unit. The drain is a simple push on type, and does not have a screw-on garden hose connector. I would prefer to use a garden hose as it is stronger, and will not crush if stepped on. I have passed this suggestion on to the seller.This dehumidifier has been running now for almost 2 weeks, and it is working flawlessly. Our home is much more comfortable, and it feels like the A/C is not working as hard. That could just be the optimist in me talking though, as I have no hard facts to back that up. This unit does take up more floor space than others we have had, but it’s worth it if it continues to keep us comfortable. The 2/5 year warranty is also reassuring.I do want to mention that the seller/manufacturer has been extremely responsive. They have provided us with recommendations that have been very helpful. They respond to questions quickly and with detailed answers. I can’t speak more highly of their customer support. It gives me reassurance they will be there if there are any problems in the future.

Great so far
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.
