Product Reviews of the Best Humidifiers of 2018

1.     Our Top Pick: Crane USA Cool Mist

After spending countless hours on testing and researching, we concluded Crane Humidifier as our most recommended pick. The benefits of this humidifier overpower its drawbacks.

We have tried and tested plenty of humidifiers, Crane Humidifier supersedes all the qualities of the best humidifiers available in the market.

Benefit#1: Air Moisturizing Capacity

Are you wondering what Crane Humidifier can do for you? Why do we consider it as our top pick? The humidifying capacity, which is actually adding an optimal amount of moisture to the air, is up to 500 feet. You can keep your grow room humid up to 24 hours.

You don’t have to worry about your plants at night. The air moisturizing capacity of this humidifier lets your plants grow sleep smoothly. Your plant will not die because of the dry air in your room.

It is not wrong for us to say that Crane Humidifier will prevent your indoor garden from unwanted respiratory problems. We tried and tested the product ourselves before making this statement.

Benefit# 2: Automatically shuts off

One of the key features of this humidifier is that it has very convenient control settings. The auto-shutoff button allows the equipment to automatically shut-off when the tank runs out of the water.

When the water level of the tank is low, and the tank is empty, the auto-shutoff sensor shuts the humidifier off. This is an amazing benefit Crane Humidifier has over other humidifiers available in the market.

The auto shut-off sensor saves power and energy, which makes the humidifier energy-efficient. It is also very safe for you to use it in your grow rooms.

Benefit#3: 1-Gallon Capacity.

All humidifiers have different water tank capacity. Some of them have a big water tank capacity others have a small water tank capacity. It has 1-gallon water tank capacity which is large enough for you to keep your room moisturized for hours.

After filling the tank one time in a day, you don’t have to think about refilling the tank all day. You can totally forget about checking the water in the tank.

You can easily fit it under your bathroom sink to fill it with water. There is no hassle about filling the tank. The room stays humid for up to 24 hours and the water in the tank does not dry out.

Benefit # 4: No need to filter the water

This Humidifier does not require any filters. You can easily use tap water to get good results. You can get clean and pure vapors from the humidifier even by using unfiltered water.

We concluded that it is one of the major benefits because it saves your money from buying demineralization filters.

However, we cannot misguide if you live in a place where there is hard water. You will have to buy an additional filter to demineralize the water to get pure air from the humidifier.

Drawback#1: Leakage of water from the bottom

We have observed, that if not maintained and taken care of properly, the Humidifier might leak from the bottom.

After using it for a couple of times, you might face the problem of the water leaking from the tank. This could be disappointing for you, but it is not something which cannot be fixed.

If you clean the humidifier properly and use it carefully, you will not have any complaint about the leakage of the water from the bottom.


Crane USA Cool Mist Humidifier is the best humidifier we have come across, which is suitable for you if you want to improve the level of moisture in your grow room for any kind of plant. No other humidifier in the market can dare to compete with it.

2.  Our choice for indoor garden lovers: TaoTronics Humidifier

TaoTronics Humidifier is our second pick among all the humidifiers available online.

We can assure you that you can completely trust us about the features and specifications of TaoTronics Humidifier. It is the best humidifier for growing room to use in summers.

You can get most out of TaoTronics Humidifier in summers because dryness is at its peak in spring and the air conditioner takes out the moisture from the air in your room.

Benefit#1: Ultra-silent Humidifier

TaoTronics Humidifier emits vapors in the air to improve the level of moisture in your room. It is an ultra-silent and very quiet humidifier. The sound it produces is less than 38dB which is so little that it won’t bother you while sleeping. It is almost non-existent.

You will be surprised to see a humidifier so silent which does its job perfectly. You will even forget about having the humidifier in your room.

Benefit#2: Instinctive LED Display

TaoTronics Humidifier comes with a digital LED display. This is an amazing feature the humidifier has. While producing the mist in the air, the LED display tells you the current humidity level of your room.

You can easily keep a track of the level of humidity in your room by looking at the LED display. The LED also has a light which can easily be switched off at night time.

Benefit#3: Adjustable mist levels.

While using this humidifier we also found out that it has adjustable mist levels. You can easily adjust the amount of mist you want in the air. It totally depends on you how to adjust the humidity levels according to the nature of the plant.

You can count on TaoTronics Humidifier to make the air in your room fresh, pure, and clean.

Benefit#5 Cartridge Filter

It is no surprise that TaoTronics Humidifier comes with a cartridge filter to clean the water from harmful bacteria.

We found out that it is the safest humidifier to use because it exhibits the purest and cleanest air by decontaminating the water. It also frees the water from bad smell and odor and leaves a fresh odorless smell in the air.

Drawback#1: You cannot use essential oils and perfumes.

Sometimes you want to fill the air in your air with a nice odor. While using a humidifier, you expect that you are able to use essential oils and perfumes to have a nice fresh odor.

TaoTronics Humidifier does not allow you to use any perfumes or oils which we think is a serious drawback. Who doesn’t want a good fresh odor in his room? A smell of lavender oil won’t hurt anyone.


We compiled and analyzed that if you want a humidifier which is silent and efficient in keeping the air fresh TaoTronics Humidifier is a good choice.
