After cleaning, refiling a humidifier is arguably the most stressful task that humidifier users cannot avoid. For this reason, humidifiers with a top filling design are a gem and are extremely effective at making your experience more pleasant and seamless.
I put this article together after testing about a dozen of the most popular top fill humidifiers myself. Below, you will find my reviews of the best top fill humidifiers on the market today in order to help you make the right choice when selecting a product. Regardless of the ease of filling, a humidifier is still supposed to be able to do its basic job well, which is humidifying, so I made sure to keep that in mind.
My first place and most recommended product among the best top filling humidifiers is the Keecoon unit. Taking a quick look at some of its qualities, it has a neat top fill design and a 1500ml/h mist output with 4.2 gallons for over 24 hours of runtime.
On top of all this, perhaps its most impressive quality is being able to humidify up to 1000 sq. ft. of room size – much more than most users would ever need.

A Brief Overview
Before I get to the full-length reviews, here’s a quick overview of my top pick, as well as four other humidifiers that qualified for my recommendation after testing.
Top Pick
1) KEECOON Top Fill Large Humidifier
As previously mentioned, this Keecoon unit checked all of my boxes with ease. It has a huge capacity that will allow it to humidify continuously for 48 hours and the ability to humidify a huge space of 1000 sq. ft. or more.
It has a sleek design, a built-in air-purifier, and a range of neat controls to make sure it is perfect for your specific requirements. This is one of the very few top fill humidifiers that I tested that could humidify a whole house or greenhouse. It’s very impressive and should definitely be one of the first ones you consider.
Other Notable Mentions
2) Elechomes Warm and Cool Mist Top fill Humidifier
This unit takes the number 2 spot due to its sleek design, helpful remote control, and easy-to-use top fill design.
It is designed to humidify a slightly smaller area than the KEECOON unit but will still be more than powerful enough for most uses.
3) Honeywell Top Fill Tower Humidifier with Digital Humidistat
Automatic humidification is the standout feature of this Honeywell unit. I could easily set my preferred relative humidity and trust it to keep monitoring the space to ensure this level was reached.
It has a slightly lacking water capacity when compared to some of the others on the list, but it still gave me a solid runtime before I had to fill it up again.
4) MOSFiATA 5L Top Fill Warm and Cool Mist Humidifier
I loved the large 5L water tank on this MOSFiATA unit, and the top fill design made it a pleasure to use. This one’s suitable for medium to large-sized rooms, and one of my favorite features was the ability to use it in combination with aromatherapy oils.
5) GENIANI Top Fill Cool Mist Humidifier
Finally, this GENIANI humidifier has a smaller water tank than most of the others that made it to the list, but it still performed well. It was very quiet when operating and also comes with the much-coveted aromatherapy feature!
5 Best Top Fill Humidifiers – My Full Reviews
1) KEECOON top fill Large Humidifiers
Awesome design
Let’s forget this is a humidifier for a minute; the looks of this device would blow anyone away. It resembles a blend of a slender aquarium and some portable digital display devices at the same time.
Now let’s come back to the fact that it is a humidifier. It has a transparent body that allows you to see through the tank to monitor the water level easily, and also a digital control soft-touch interface on the front side.
This interface makes it easy to interact with the humidifier and perform basic tasks like varying humidity or using its installed automatic functions, which are discussed in the latter part of this review.
Capacity
In addition to its looks, the capacity of this unit did not disappoint. It has an incredible mist output rate of 1500ml/h on the highest setting. That’s just extraordinary and can conveniently cater to the needs of rooms up to 1000sq. ft. In the world of the best top loading humidifiers, this device is unmatched.
High capacity with poor water holding quality would put you through more stress than you can imagine. This is why I was extremely pleased with this KEECOON model’s 4.2-gallon water tank. After I had filled it up, I turned it onto its highest setting, and the water tank didn’t run dry until a full 47.5 hours later.
Top fill and energy saving
Of course, as I was only considering top fill humidifiers for this article, only top fill products made it to the list. This humidifier can be easily filled from the top by simply removing the cover and pouring in water. I could look through the transparent tank to easily gauge the water level and avoid an overflow.
For its size and capacity, energy consumption was something I was worried about. However, its energy-saving design ensures that you get this premium service at a low energy cost. It is energy-saving; therefore, that bill spike will not be a result of running this guy.
2-in-1 device
Aside from being primarily a humidifier, this unit also cleans the air while operating. Therefore, it is a 2-in-1 unit, where you get the effect of an air purifier and humidifier for the price of a humidifier. That’s one more reason why it claimed my top spot.
Automatic mode and easy mobility
This unit was also able to run intelligently. I could select a precise humidity range on the control panel and watch the humidifier increase or decrease its output accordingly. After choosing this, the unit continued to monitor the humidity and ensure it was in the target range – shutting off its output when it had achieved it.
One obvious appearance feature that we have not discussed is its wheels. It sits on 4 of them, allowing you to push it around depending on where you need it. I was very pleased with its mobility.
Remote control and safety auto-shutoff
Another digital convenience feature is seen in its remote control. With the 5-meter range remote, I could vary the settings of the humidifier from the comfort of my couch. The remote control covers just about every feature it possess
