If you need the best humidifier for plants, but you don’t know where to start, this post will give you a headstart. I’ll share my pick of the very best plant humidifier and other great options including how to shop for them even if you have zero knowledge about humidifiers.
For starters, why would anyone need a plant humidifier in the first place?
We love our houseplants too much to let them struggle and die on us due to inadequate humidity – a problem which is made worse with closed-up homes with heating systems and all.
Besides, for those plants that prefer a high level of humidity, the low humidity commonly found in homes in winter can be a shedding experience as their foliage yellows, dries up, and falls off.
In fact, according to the University of Missouri, the average interior setting during winter has a relative humidity lower than that of the Sahara Desert!
Given, most houseplants do best at a relative humidity of 70 to 80 percent, a level that is often difficult to maintain in the home.
Thus, the only effective way to increase the humidity around plants and keep them healthy is to use humidifiers.
So, what should you look out for when shopping for the best humidifier for plants?
First and foremost, you should consider the size and capacity of the humidifier. This will depend largely on the size of your room. If your rooms are smaller, you’ll need a small humidifier and vice versa.
Keep in mind that a large humidifier in a small room is almost always a bad idea due to condensation of the extra humidity produced thus causing other problems like foggy window panes and bacterial growth on your plants.
Here’s more on how to shop for the best humidifier for plants:
- Check the basic operating design. Most humidifiers have several options such as ultrasonic which is considered the most effective with others like evaporative design and steam vaporizers.
- Choose the type of control. There are mechanical analog humidifiers that you need to control manually or digital electronics which work almost automatically.
- Determine whether you need cool or warm mist. Initially, the warm mist humidifiers were popular but the danger of burns especially children discouraged their adoption. Nowadays, cool mists are most common due to their efficient energy use.
- Consider the ease of operating and maintenance. Some humidifiers are easy to operate than others. Therefore, consider the ease of removing tanks to refill, filter changes, and the availability of those accessories.
- What’s your acceptable noise level. No humidifier is 100% quiet. Some are low noise while others are loud. All the same, ultrasonic humidifiers are the quieter of all.
Rest assured, whatever your budget, expectations, or needs, this guide on the best plant humidifiers will feature the perfect option for you. This is because I’ve sifted only the best options to confirm which ticks every plant humidifier box.
And, my outright pick at the moment is the Everlasting Comfort Cool Mist Humidifier - an ultrasonic humidifier with a 6L tank that works in rooms of up to 500 sq. feet and lasts approximately 50 hours.
Alternatively, the AquaOasis Cool Mist - an ultrasonic humidifier with multiple mist settings and a 360-degree rotating nozzle can still do the job for you.
However, if you’re tight on a budget and looking for something portable and efficient, then, you should check out this Portable Mini Humidifier that is easy to carry around whenever the need arises.
So, you can be sure you’ll find exactly the right plant humidifier for you.

The Best Humidifier for Plants in 2022
Everlasting Comfort Ultrasonic Cool Mist Humidifier (My Outright Pick)
The Everlasting Comfort Cool Mist Humidifier is an ultrasonic humidifier with a 6L tank that works in rooms up to 500 sq. feet and lasts approximately 50 hours.
This humidifier also contains an essential oil tray that circulates fragrant oils into the cool mist, giving you a pure and fresh smelling aroma throughout your home (added advantage) as you humidify your houseplants.
Moreover, this humidifier is filterless hence saving you from the ongoing filter replacement costs. In addition to its quiet operation, the Everlasting Comfort Ultrasonic Cool Mist humidifier has a LED-lit water level marker on the side (helpful).
Plus, it shuts off automatically when out of water hence safe to use in baby rooms and bedrooms.
When it comes to size, this humidifier has a perfect size for any space in your house. The humidifier is compact and isn’t too big so, it blends in perfectly well in any room next to other items.
Cleaning this humidifier is quite easy since there are no filters and you don't have to clean it too often. Also, you don’t have to use fancy products or special expensive cleaning products to clean it.
On top of all this, the Everlasting Comfort offers you a 2-year replacement policy should anything go wrong with the humidifier.
However, there are a few downfalls from this humidifier, though not necessary to call it a deal-breaker but worth mentioning.
First and foremost, although the humidifier operates quietly, expect some frequent and noticeable gurgling noise as the water runs through the base.
Also, refilling the tank seems hectic as compared to the top-fill humidifier.
This is because every time you want to fill it up, you have to take the entire thing apart (take the large container off), take it to the sink and fill it up then reassemble it. And every time you do this, the container leaks water everywhere.
All the same, this is the most solid plant humidifier you can get!
