Pros
Pro Also acts as an air purifier
In addition to its dehumidifying capabilities, this device filters the air from allergens, mold, mildew, and pollen using a built-in HEPA filtration system. This makes the air around you fresher and healthier. You can select between using only the dehumidifier or the purifier functionality, or both.
Pro Saves space and money
This device is a great alternative to having two devices: an air purifier and an air dehumidifier. As it requires less maintenance, takes less space, and consumes less energy compared to two separate units, it's much more beneficial to have this two-in-one machine.
Pro Can be left unattended
There are several smart features on this dehumidifier that allow it to be left unattended. You can set the desired humidity level and once it’s reached, the machine will maintain it. If a drainage hose is added, you won’t need to worry about emptying the bucket. The unit will also defrost itself if the coils get frozen and if a power outage happens, the device will restart automatically.
Pro Comes with child protection
The unit has a child lock system, so that your children don't mess around with the controls.
Pro Excellent for use in spacious offices
This powerful air dehumidifier is excellent for office use, as it can cover a massive area and work fully autonomously. You can simply program it to start at the beginning of the workday, and stop after the office hours are over.
Pro Highly autonomous
Once an external drainage is connected and everything is set up via the control panel, the unit can run automatically, without supervision. It will maintain the desired humidity level and will turn on and off according to the timers. If there is any power outage, it will resume its operation with the previous settings, once the power is restored.
Pro Has an intelligent timer
A unique feature of this dehumidifier is that you can set a delayed start and a delayed stop at the same time. For example, you set a delayed stop and then have it start again after a couple of hours from that period.
Cons
Con Can't be brought to California
It isn’t CARB certified, so you can’t buy or ship it to California.
Con HEPA filter is hard to reach
In order to clean the HEPA filter, you need to be sure that the water reservoir is empty. Otherwise, you will not be able to take it out.
Con Can get quite loud
When the fan and compressor are running at the highest settings, it does get pretty loud, which can be annoying.
Con Generates lots of heat
Like many other large dehumidifiers, this one generates quite a lot of heat when running, especially in smaller rooms. While this can be a good thing in the winter, it is the opposite during summer.
Con Small water tank
Despite the large coverage, it only can hold ten pints of water in its reservoir. If you are planning to use it without the drainage, expect having to empty it often.
