Impressive unit
By 'Rajveer Rosario', Reviewed on February 22, 2021
The unit runs well, is relatively quiet, and well ventilated. The function matches the description and is cheaper than other similar units. I have been running it for 2 months and it is still very powerful. My crawl space is not as musty as before. As it will be affected by rain and weather, what impresses me is that it is still running. Will buy another one in the future.
Effectively control the humidity level of the garage
By 'Lacy Thornton', Reviewed on February 07, 2021
I finally managed to reduce the humidity in the garage. I live in a very humid place and this fan is very useful for dehumidifying the space. I like the accuracy of these sensors, although I do not expect them to achieve such accuracy, this is a surprising surprise. It is installed on the vent of the garage, so I really don't have any problems, because once the garage door is closed, I can't hear anything. I am satisfied with the overall purchase and would recommend it to anyone.
If it continues... it will be the best item I bought
By 'Ezekiel Dunne', Reviewed on February 01, 2021
I got this fan today, I have connected it to the power supply and took it out of the packed box...this fan left a deep impression on me. This will be a basement exhaust fan, and the programming of this fan is great. I will not take full advantage of it until summer, but I think it will be great. My main problem is humidity, so it should be summer before full use.
Great product
By 'Tulisa Hutton', Reviewed on January 25, 2021
The product works as advertised. Easy to install. My application is a 3.5-foot crawl space under the house, about 600 square feet. When I have vents on 3 sides of the house, my goal is to use this fan system to draw the air out and dry it to reduce/eliminate the musty smell.
Exactly what I need
By 'Sabiha Simon', Reviewed on January 18, 2021
High-tech, high setting, suitable for general basement ventilation. I made custom wooden window panels to install two units in the basement windows. Even when smoking, with these dual fans, all the smoke can be ventilated outdoors without the smell of smoke upstairs! They minimize the impact of cigars on the family and the cigar house itself. Living in Minnesota is not a viable option for smoking outside! Love them!
Elaborate crawl space fan
By 'Ameer Knapp', Reviewed on January 11, 2021
I need a fan for small crawl space under a building that has a hidden air leak for several months. To install the dehumidifier, I will have to crawl about 60 feet in the mud. This product is very suitable for the ventilation holes of standard buildings and has a foam seal to prevent air leakage from around the equipment. It contains a built-in switch that will automatically turn off the fan once the desired humidity level is reached. It is made of sturdy stainless steel and has two sturdy fans.
Humidity insurance
By 'Libbie Lloyd', Reviewed on January 04, 2021
I have a new long and narrow house with crawl space. This kind of foundation has a greater risk of damage from moisture (including mold) than a slab or basement foundation. I installed two of the fans in the crawl vents as a relatively inexpensive form of high humidity protection. The DC motors in these fans have significant design advantages, and the fans are indeed very quiet. Besides, the system reduces the humidity level to prevent the growth of mold while expelling odors and other harmful pollutants from the home.
