What Is Humidity?

By understanding exactly what humidity is, why our plants need it and how much humidity is enough, we can modify our plant’s environment properly, so they’ll truly grow up.

According to the Oxford dictionary, humidity is the condition in which the air is very warm and damp. In other words, humidity is simply a measure of a large amount of water vapor (the gaseous state of water) presenting in the air.

Why is Humidity Essential for Plants?

Every plant inhales carbon dioxide (CO2) through their leaves. This colorless gas appears in photosynthesis. When a plant expands its leaf pores to absorb CO2, an amount of moisture can escape out of it. This means the plants will sweat the water vapor (moisture) into the air every time they breathe.

Dry air causes the plants to drop moisture rapidly than the humid air does. No sooner does the water in the leaves evaporate speedily than the plant loses the moisture. If the leaves lose water quicker than the absorbing rate of the roots, strike happens.

It has to inflict on itself before starting this evil process. In order to prevent losing more water, a plant must close all of its leaf pores. This helps hold up the flow of water vapor from the plant, but it also decreases the intake of CO2. Therefore, the cells die and your plants will look tired and ill.

In contrast, when the plants live in the right humidity environment, they thrive. The moister the air is, the less water the plants lose from their leaves. In other words, humidity plays an important role in the plant development.

What’re the Benefits of a Plant Humidifier?

At its simplest, humidification is the supplement of water into the air. All of us also prefer suitable moisture in the air to be comfortable, so do the plants! The moisture shouldn’t be too high or too low in comparison with the air temperature.

By adjusting the moisture in your home, the best plant humidifier will provide you and your plants with the healthy and comfortable environment.

How to Buy the Best Plant Humidifier?

There are two major types of plant humidifiers: evaporative humidifiers and ultrasonic humidifiers. Each of them has its own features and functions. Here are some must-have characteristics of every plant humidifier that you need to know.

  • Anti-Bacteria: This is the most important factor. An anti-bacterium plant humidifier will pure your air and offer you a healthy living environment.

  • Running Time: The best plant humidifier has to run continuously in at least 12 hours (over 24 hours is perfect). You don’t want to refill the water constantly, do you?

  • Tank Capacity: Along with the running time, tank capacity should be considered. A tank that can contain a gallon (about 3.8 liters) of water or above is an ideal choice.

  • Safe Design: Since humidifier is an electrical device, it can cause burns whenever it’s running. A safe design will keep your family out of dangerous situations. Let focus on the material, original and plugs.

  • Whisper Operation: In order not to be bothered by the noise that the humidifier emits when it’s running, you should choose a product that operates quietly. About this feature, I highly recommend the ultrasonic plant humidifier.

  • Maintenance and Clean: A plant humidifier is easy to come dirty, so it’s better for you to have a model that can be easily cleaned.

Product Reviews – The Best Plant Humidifiers

1. Honeywell HCM350W Germ Free Cool Mist Humidifier

This product is scientifically recommended thanks to the Ultra-Violet Light (UV light) technology, which has a strong effect on disinfecting the water once it goes through the system.

With this technology, nearly 99,9% of bacteria, mold as well as virus are killed. So, you can have the peace of mind that the moisture that it emits into the air is completely free of germ. Additionally, the 3-speed settings on its body allow you to adjust the moisture output easily, and the sound level makes it even quicker to use.

What I also like about this unit is the tank. It fits the sink perfectly and can be filled without toppling over. If you don’t want to continually refill it, this large-capacity model is ideal for you.

What else? The filter needn’t be replaced too often, maybe every 6-7 months or so. Honeywell can run up to 24 hours after filling on low setting, so your plants will enjoy humidity all day. It’s not only superb easy to use but also easy to clean and maintenance.


Pros

  • Superb easy to set up and use
  • Large capacity
  • UV light technology
  • Has a 24-hour run time

Cons

  • It’s pretty bulky in a small space.
  • A misleading photo in the user guide

2. Vicks Warm Mist Humidifier

Vicks is a mainstay in plant humidifiers. This product operates by using tap water and electricity to create a heated mist, which works effectively for my tropical plants. Its tank has 1-gallon/3.8 liter capacity that allows operating for at least 12 hours continuously.

Moreover, it has a capability of turning off automatically once being out of vapor to protect itself from unit damaging. Additionally, there is an unobtrusive night light switch that has 2 settings: high setting for maximum moisture in large rooms and low setting offering a comfortable humidity in average-sized rooms.

Its design also omits up to 95% of bacteria and prevents maximum white dust. It works when the steam combines with the dry air in the cooling cavity; then the warm air will be released into the room and contact to your plants.

Besides, using Vicks is really convenient because of its quick installation, just by 3 simple steps: remove packaging; remove water tank, rinse and fill; place back on the base and turn it on. Cleaning is also relatively painless. All you have to do is unclipping and removing four components, then cleaning and putting them back together. However, weekly and end of season maintenance require a little more work.


Pros

  • Quick set-up
  • Easy to clean
  • Automatic shut-off
  • Reasonable price
  • Can be carried

Cons

  • On the high setting, it makes a bit of noise
  • Low output

3. PureGuardian Ultrasonic Cool Mist Humidifier

This humidifier is ideal for medium and small rooms. It’ll guard your plants against the matter caused by the dry air. The tank contains a gallon of water, which is pretty good. However, what make its tank special is the Silver Clean Protection feature.

Unlike some other humidifiers that increase the amount of slimy mold on the water surface in the tank, this one can find and clean any mold thanks to the Silver Clean feature. It also disperses a fine mist steam into the air without making any noise thanks to the Ultrasonic technology.

That’s not all. With a light indicator, PureGuardian is great as it lets you know when you need to refill the tank. On its base, there are 2 buttons. While the left one has 4 functions: low, output, mid power and off, the right one will turn the light off.

The medium-high will run up to 18 hours, whereas the high setting can operate within no more than 14 hours. Remember that its running time also depends on the speed level as well as atmospheric conditions. Especially, I usually keep the blue night light on as it gives my humidifier a nice look without being disturbed.


Pros

  • Simple and elegant design
  • Ultra-quiet
  • Silver Clean Protection tank
  • Ultrasonic technology
  • Two output settings

Cons

  • It’s quite bulky.
  • Some customers have problems with cleanings

4. Aroma Oil Diffuser, Ultrasonic Cool Humidifier

This unit is good-looking, compact and nicely-made. It comes with a good stone filter that offers a soft, pure mist. The filter also eliminates the bad smell as well as the mold of the water. With the 2.8 liter tank, it can run over 15 hours without refilling. Highly recommend it for medium or large rooms.

Interestingly, the Ultrasonic model features a seven-color night light, so you can leave it on whatever color you like! Moreover, it has an extremely low running sound. If you want to adjust its vapor flow, let control knob do it. Besides, the longer mist stream will provide your floor with the perfect coverage and leave no condensation.

In comparison to my previous humidifiers, this one has aroma diffuser; therefore, we can both humidify the air and enjoy our favorite oil at the same time. There are 2 dispensing trays for the essential oils. One is at the bottom of the side of the tank and the other is at the top where the mist comes out. This diffuser gives you so much more scent from the oil.

Smart design with automatic shut-off function will turn off itself as long as the water level is low or when the water tank is removed. It is also easily cleaned thanks to three components. What should be considered? The price is so good!

  • Nicely-made

  • Seven-color night light
  • Aroma diffuser

Cons

  • The tank sometimes is imbalance once being refilled.

This humidifier is totally pleased me! One of its superior features is the LED display, which has 5 modes: ON/OFF, TIMER, ANION/SLEEP, MIST +/- and HUMIDISTAT. This convenient display provides useful information such as the humidity level and modes you’re using.

Once being out of the water, an icon on its display will notify you. Despite having only 1.1 gallon/4 liter capacity, it can work in 15 hours and lasts well the whole night with a chockfull tank of water.

Moreover, it comes with a microporous cartridge filter. Thanks to it, micro-organisms as well as the bad odor in the water will be absolutely omitted. It’s also convenient for you to refill the water because of two handles on the top and the bottom. Additionally, this unit runs quietly (just produces approximately 38 dB of noise).

Besides superb easy-to-use, this humidifier is simple to be cleaned. You just turn the tank upside down, unscrew and fill the filter with water, then screw the filter back in. As an added bonus, it has the night mode that can be adjusted up to your mind.
