I recently had the opportunity to try out the Bluedeep dehumidifier and I must say, it exceeded my expectations. After experiencing issues with my previous dehumidifiers, I decided to do some research and came across the Bluedeep. Not only does it come with outstanding features, but it also comes at a much more affordable price compared to other brands like Santa Fe.
One of the features that I really appreciate is the auto shut down at cold temperatures. This prevents the compressor from overheating and ensures the longevity of the machine. Additionally, the remote control is a convenient bonus that allows me to adjust settings from a distance.
Last fall, I purchased the 145 pint dehumidifier and I was truly impressed with its performance. I had been struggling with humidity and mold issues in my finished basement and my previous 30 pint dehumidifier wasn't cutting it. The Bluedeep made an immediate impact and effectively brought down the humidity levels.
However, recently I encountered an issue with the machine. The compressor wasn't cooling the coils enough to condense the moist air and I suspected a refrigerant leak. I contacted customer service and they were extremely helpful. They asked me to provide pictures of the compressor and piping, and after confirming the issue, they promptly sent me a new dehumidifier without any hesitation. It's reassuring to know that the company stands behind their product and provides excellent customer service.

I recently purchased this dehumidifier for my basement, and I have been extremely satisfied with its performance. My basement, which is approximately 1300sq ft, now maintains a comfortable humidity level of 55% RH. Here are some of the features that I appreciate about this unit:
Firstly, the dehumidifier is compact in size, making it easy to place in my basement without taking up too much space. Additionally, it operates quietly, with a noise level of around 60-65dB, which is barely noticeable even when I am in the same room. This is a significant improvement compared to other units I have used in the past.
The dehumidifier is also relatively lightweight, considering it has a sturdy metal chassis. This makes it more durable compared to units with plastic bodies. I appreciate the inclusion of a port for a remote humidistat, as it allows me to control the unit from a convenient location even if it is placed further away.
I was impressed with the packaging of the product as well. The foam used for protection was easy to handle and dispose of, without leaving any messy residue. It shows that the company pays attention to detail and cares about the customer experience.
While there are a few areas where this unit could be improved, it is important to note that these are not deal-breakers. For instance, I would have preferred if it had a drain pump, but this was not advertised as a feature, so I can't fault the product for that. It operates on a gravity drain system, which still works well.
In comparison to residential-type units I have used in the past, this dehumidifier is a definite upgrade. It is more substantial in terms of weight, weighing just under 50 pounds, but it is no louder than the residential units I have used. It effectively removes moisture from the air, eliminating the need for continuous cycles and preventing the coils from freezing up. The unit also includes an automatic defrost cycle, which is a convenient feature.
A few observations about the unit overall: the product images on the Amazon page may appear gray, but the unit is actually purple. This might be a consideration if you plan to install it in a visible location. Additionally, the green digital humidistat always displays the current humidity level, even when the unit is powered off. To turn off the humidistat, you need to unplug the unit. The set level of humidity is only displayed when you adjust it using the arrow buttons.
The unit requires a drain for proper operation and cannot be placed directly on the floor. It is recommended to prop it up on cinder blocks or another elevated surface. The blowout from the unit is strong and warm, so it is important to consider the placement and orientation of the unit to ensure that the blowing air does not cause any issues.
3. Compact Sentinel Hd55: Ultimate Commercial Dehumidifier For Troubled Spaces
The Alorair H55 (Blue) Sentinel dehumidifier is truly one of the best products available on the market today, especially when it comes to its operating capacity. My past experience with dehumidifiers has been quite disappointing, as I have had to deal with multiple failures and poor quality from various manufacturers. I have tried brands like Frigidaire, Friedrich, and Hense, and they have all proven to be unreliable and designed to fail within a short period of time.
One of the main reasons why these dehumidifiers fail is due to their bad design. The evaporator coils, which operate under high pressure 410 Freon, are made with thin copper tubing and packed with aluminum cooling fins. These components, held together with carbon steel plates, are prone to formicary corrosion caused by the dissimilar metals in contact with each other in a damp environment. This corrosion leads to the failure of the evaporator coil within 24 months.
Another design flaw is the placement of the humidity sensor directly in contact with the evaporating coil. This causes multiple false starts for the dehumidifier compressor, as the coil remains wet even after the unit shuts down. The moisture released when the coil dries out triggers the sensor, leading to excessive cycling on and off. Moreover, these units are not repairable and are intended to be disposed of, which is quite wasteful.
Fed up with these issues, I decided to research crawl space dehumidifiers and came across the Alorair H55. Unlike most crawl space dehumidifiers that are overpowering for my needs, the H55 is compact and perfectly suited for my relatively small encapsulated crawl space. Its quality design stands out, with a coated coil that protects against premature evaporator coil failure due to formicary corrosion. The unit is held together with stainless steel plates, ensuring durability.
Another great feature is the separation of the humidity sensor from the evaporator coil. The sensor is located on the lower end of the unit, minimizing false triggering by evaporating moisture. In fact, there is even an option for a remote controlling sensor with a 25-foot cable, allowing for full separation from the evaporator coil. The unit also has a MERV 8 removable filter to keep the coils clean.
On top of its efficient performance, the Alorair H55 operates quietly. It is so quiet that I can only tell if it's running by putting my ear against the floor. Additionally, I highly recommend using the hanging unit installation method, as it minimizes vibration conduction and allows for more effective removal of humidity when running the gravity drain pipe. Placing the unit directly below the floor joists is also more efficient, as humidity rises and can be effectively removed during operation.
The accuracy of the humidity control is impressive as well. While the humidity sensor operates to the nearest 5%, the actual humidity setting can be adjusted within 1% intervals. I have a separate hygrometer sensor in the crawl space, and this unit is able to maintain a steady humidity level of 41% with a variation of only 1% when using the remote controller. When using the sensor on the unit itself, it maintains a steady 40% humidity with no variation. This level of precision is far superior to the other dehumidifiers I have owned, which operated with variations of +/- 5% at a 45% setting.
Although I did encounter some initial problems with the first unit delivered, the support staff was very responsive and arranged for a replacement unit to be shipped to me within two days. They even provided a return label for the defective unit at no cost. It is worth mentioning that it is advisable to save the shipping box for any future returns.

What are the signs that I need a crawl space dehumidifier?
There are several signs that may indicate the need for a crawl space dehumidifier. Firstly, if you notice musty odors in your home, it could be a sign of excessive moisture in the crawl space. Additionally, if you observe condensation on windows or walls, or if you see mold or mildew growth in the crawl space, these are clear indications of high humidity levels.
Another sign is if you experience increased allergies or respiratory issues when spending time in the home. High humidity can promote the growth of allergens such as mold and dust mites, which can have adverse effects on indoor air quality.
Furthermore, if you notice warped or damaged wood, such as sagging floors or rotting beams, it could be a result of moisture damage. In such cases, a crawl space dehumidifier can help regulate moisture levels, prevent mold growth, and protect the structural integrity of your home.
