Moiswell is a newish dehumidifier brand from Kentesh LTD, based in London, UK, with connections to China. The company was first registered in February 2021 and sells another brand of traditional residential dehumidifiers called Colzer.
The Moiswell brand offers crawl space and commercial dehumidifiers at 145 pints per day and up to 320 pints for its largest devices.
They aim to bring commercial-level dehumidification without the usual high price from leading brands, such as AprilAire, which costs $2000 for a similar dehumidification performance. The Moiswell 145 costs $599.99 without a pump and $699.99 with a pump. This review is for the pump version.
|Why You Should Trust This Review|
As with all the dehumidifier reviews we produce here at HouseFresh, we bought the Moiswell 145 pint with our own money and tested its water removal ability and performance over time. We often will update our reviews if things change, such as when our pump died on our hOmeLabs 4000 dehumidifier last month.
This is our process:
1. We turned on our unit in our basement, the most humid area in our home.
2. We used a Govee WIFI humidity sensor to track the dehumidifier’s performance over time, recording regular humidity levels every minute.
3. Our electricity meter shows how much energy is used at the maximum usage.
4. We exported all our data and use Flourish to provide data visualization to show how well it performed.
TL;DR A Powerful Crawl Space Dehumidifier for Even the Largest of Damp Basements

Designed With Crawl Spaces in Mind
Its height is 13.3 inches, which is small enough for even the tightest crawl spaces.
I am currently using it on my basement floor as I haven’t got around to mounting it on my floor joists. It weighs 70 lbs (or nearly 32 kg), so I will need help from someone else to mount it.
That being said, I was glad to see Moiswell added handles at the top of the dehumidifier, making it easier to move around – yes, it is still heavy but the handle bars make picking it up A LOT less challenging.
When I first unboxed the Moiswell 145 Pint Dehumidifier I immediately noticed how much smaller it is when compared to the other residential dehumidifiers we have tested here at HouseFresh.
Just to show you one example, check out the hOmeLabs 4000 – a residential air purifier that is super popular right now:
It looks nice but the honest truth is that the hOmeLabs 4000 would be way too big for any crawl space, so if you’re looking for a dehumidifier for a tight space, then the Moiswell is your best bet:
The control panel is really straightforward. It has four buttons, one for switching on/off, two for adjusting the humidity target and a timer function, so you can set it up to work for a specific amount of time.
I have connected the Moiswell to a Philips Hue Smart Plug, which means I can treat it like another smart home gadget. This allows me to fit the Moiswell into my existing automated routines for the house, plus it means that I can turn the dehumidifier on/off from anywhere as long as I can access the internet.
|💡Pro Tip: If you are into building a smart home, the Philips Hue system is a cheap way of turning any gadget into a smart appliance.|
Washable Filter + A Pump, Drain or Even External Pump
All dehumidifiers need to keep dirt from entering the unit, as it can cause damage and lead to failure in the future.
The Moiswell Defender XP70 avoids this by making the washable filter slide out easily for cleaning.
After using this dehumidifier in my basement for two months, I have to say that the Moiswell has a good-quality filter. It is much better than what you get with most of the residential dehumidifiers we have reviewed.
I look forward to using the internal pump. You can use the gravity drain to connect a hose that will flow if you don’t go against gravity.
With the pump option, you also have an internal pump that can move the water vertically up to 16.5ft, which is excellent for use in basements where the drain is often higher than the basement floor.
The Moiswell 145 Pint dehumidifier also offers you the option of using an external pump, allowing you to move water anywhere, depending on the pump’s power.
It’s worth noting that these commercial-style dehumidifiers save space by not having a water bucket, so you will need a hose to remove the water. There is no option just to have the unit collect internally.
I am excited to see over the long term how well the pump performs, as after less than 12 months, our hOmeLabs dehumidifier pump failed and I saw that this happens quite a bit with residential-style units.
|🤓 I have noticed that many of the more prominent brands (Honeywell and Frigidaire) don’t have as many residential-style dehumidifier units with pumps, which might be due to returns.|
I hope this dehumidifier has a higher-quality pump and won’t fail me, but I will update this review if it does.
Keeps My Humid Basement Dry
I tested the Moiswell Defender XP70 in my very damp basement built in the 1890s. This space regularly gets very damp, reaching up to 74.1% humidity. Since the hOmeLabs pump failed, my basement had accumulated a lot of humidity so it REALLY needed drying out. This set the perfect conditions for a test.
I used the internal pump to move water to an external drain outside my basement and was glad there was no water bucket to change. It would likely need changing multiple times a day.
To measure the humidity levels over time, I used my Govee WIFI humidity sensor that tracks current humidity every minute. Using this data, I can share below how the Moiswell 145-pint dehumidifier helped to reduce humidity levels to a comfortable level:
Noise Levels Test Results
When running, the Moiswell 145 Pint dehumidifier generated up to 58dB, so you can’t hear it on the ground floor. I liked that the sound was continuous as it helped to blend into the other sounds around.
But sound levels are a personal thing, so feel free to check out the video of the Moiswell Defender XP70 running in my basement:
Electricity Costs Associated To Running a Moiswell 145 Pint Dehumidifier: $541.37 Per Year
Dehumidifiers use a process similar to air conditioners and can use much more electricity than expected. It’s a little tricky to measure the exact amount of electricity a dehumidifier will use, depending on the current humidity conditions and settings you set up.
The dehumidifier must run harder to reduce the humidity if it’s very humid. When it reaches the target level, it will stop until the humidity levels increase again.
When we tested the Moiswell 145 pint when it was in humid conditions, it pulled 514.96 watts, which, if we assume it will run for 24 hours per day every day of the year, will be $541.37 which I think is likely much higher than will be your usage but worth keeping in mind as these large commercial units do use a lot of energy.
I am impressed with how well the Moiswell Defender XP70 dehumidifier reduced the humidity in my 2000 sqft damp basement. The product looks well made and while it doesn’t have any smart features, I could turn it smart by connecting it to my Philips Hue system.
If you have a sizeable damp basement, this commercial unit would be a better investment in the long term, especially considering how many residential-style units with pumps fail.
If any issues arise, I will continue to update this update, but as of now, this is a powerful, well-built unit for a price that makes it much more affordable than better, well-known brands.
We calculated the monthly energy consumption costs with the help of the Department of Energy’s appliance energy calculator. We calculated yearly costs associated with running Moiswell Defender XP70 for 24hs a day for 365 days. We ran this calculation utilizing the U.S. average utility rate of $0.12/kWh as of September 2023.
