Best Humidifier For Plants: Non-negotiable Buying Facts
When choosing the best humidifier for plants, a very important factor to assess is the performance of the air humidifier i.e.
its operating time and the size of the room that it can humidify effectively.
autonomy is closely linked to the capacity of the tank and the possibility of adjusting different levels of vapor emission.
One observable feature is that the more water the tank can hold, the longer the humidifier will be able to operate without interruptions due to its exhaustion.
While the possibility of setting a low emission level makes it possible to further extend the duration of the water supply.
Indicatively, a 4L tank corresponds to approximately 12-15 hours of autonomy with minimum emission, at least for ultrasonic humidifiers.
Boiling devices, on the other hand, consume their stocks a little faster, and for the same capacity (4L) offer a slightly shorter autonomy, between 9 and 11 hours.
The size that a humidifier is capable of effectively humidifying depends on the maximum amount of vapor it can emit, measured in ml/h.
Low emission humidifiers, around 200ml/hr or less, are suitable for small rooms of less than 20m², while higher emission devices, 400ml/hr or more, can efficiently serve rooms of 50 to 60 m².
A major factor of interest to allergy sufferers and those whose respiratory tracts are particularly sensitive and irritable concerns the systems for sanitizing the vapor or air emitted.
The most sophisticated models of air humidifiers, usually ultrasonic, are often equipped with filtering systems or other means of disinfecting the water in the tank.
These can range from a simple coating of the internal walls with silver ions, effective in neutralizing bacteria, to microporous ceramic filters capable of capturing and retaining both microorganisms and mineral particles in the body.
Air cleaning Ability
Regarding the effects on the air, some models are equipped with a built-in ionizer, which negatively charges the emitted vapor so that it binds to particles and allergens dispersed in the air, favoring their deposition on the soil and surfaces.
However, it must be said that in recent years there has been some skepticism towards humidifiers with ionizers and all ionizing equipment for the treatment of air in general.
This is because the generation of negative ions by a humidifier with ionizer also has the side effect of producing ozone and this gas is harmful to health even when inhaled in small amounts.
Finally, some high-end models are also true air purifiers and adopt air suction and filtration systems in addition to water.
You should be able to ask, at this point, what is more, appropriate between an air humidifier or a purifier.
It all depends, of course, on what kind of problems you want to solve: a purifier is excellent for relieving people with allergic rhinitis (to pollen, dust mites, or animal hair), but in itself, it has no impact.
on-air humidity. On the contrary, the antiallergic action of an air humidifier is generally not as effective, since humidification is its main function.
Another very interesting factor to evaluate in a humidifier is the functions with which it has.
We have already mentioned how some models, usually mid-and high-end ultrasonic models, come with an ionization feature that helps clean the air of dust and allergens dispersed therein.
However, this is not the only function that can be found on an air humidifier.
The most common and easiest to find is an automatic shutdown, which allows the device to shut down and standby when the water level reaches levels too low to continue operating.
The other functions that you may come across are as follows:
In a humidifier with a timer, you can set a preset run time, even up to 12 consecutive hours or more
allows you to adjust the emission intensity to different levels, a useful function if you want to obtain a faster result or if you want to humidify a large environment
Regulation and maintenance of humidity percentage:
in humidifiers with an integrated hygrometer, you can specify the percentage of humidity you want to achieve in the room.
The presence of a hygrostat in parallel then makes it possible to maintain it automatically
this is a silent operating mode, generally with minimum emission, sometimes accompanied by an additional guide-me-home lighting function
more common in hot and evaporative humidifiers than in ultrasonic humidifiers, it generally consists of a tray in which aroma drops are poured (based on essential oils in many cases ) to diffuse in the air.
Humidifiers with an essence diffuser are often found on the market also under the name of essential oil diffusers.
In this case, they are ultrasonic models with a reservoir of very small size and capacity, but suitable for use with essential oils without the risk of damaging the transducer.
As in these cases, the main function is to perfume the room.
An ultrasound diffuser has a generally very low flow rate and is not able to humidify effectively except in a very small room.
Finally, it may be useful to assess the heaviness and complexity of cleaning the air humidifier and whether there are recurring costs, for example for the periodic replacement of certain filters.
Firstly, we have to understand what type of humidifier we have because of course, the cleaning and maintenance operations are different depending on the type.
One thing remains the same for everyone: cleaning the tank.
Regardless of the humidifier, the tank should be cleaned once a week.
This will prevent the growth of mold, and prevent it from being dispersed into the air by the humidifier.
This is because breathing in mold spores are harmful to health!
How to use an air humidifier?
Examine your device’s battery charge status before using it
If your model is running on a battery, check to see if the battery is fully charged before using it.
Otherwise, your device may suddenly stop while humidifying.
To overcome this problem, opt for copies that are powered by mains. They have unlimited autonomy.
Remember to wash the tank of your air humidifier before using
For first use, we recommend cleaning the tank of your device before using it.
To do this, you need to remove this component and unclog it with water and mild soap.
This action ensures that you get rid of manufacturing odors from your humidifier when you turn it on.
Put water in the tank of your equipment
Before turning on your humidifier, don’t forget to pour water into the compartment provided for this purpose.
The most recommended is distilled water because it does not contain additives.
Also, you can run physiological saline in it instead of water.
This is recommended especially if you have small children. As a result, the risk of lung diseases will be reduced to a minimum.
Clean your device frequently to continue using it healthily
Over time, bacteria can grow in your device. To eliminate them, wash them at least twice a week. With this in mind, water and a mild detergent will do just fine.
To effectively kill germs, add little white vinegar and hydrogen peroxide.
Best Indoor/Outdoor Plant Humidifiers: Buying Question
How to make an air humidifier?
To build an air humidifier, start by creating spirals of wire. Then wrap each one around a test tube.
Prevent these two components from coming into contact by using insulators, such as beads. Connect the containers with another wire, taking care to hold them.
Then place everything on a radiator, using both ends to secure it. Finally, pour water into the tubes and turn on the radiator.
Are Air humidifiers needed in my house?
To find out, use a hygrometer already. You will then know the humidity level in the room to know if this type of device will be necessary or not.
Of course, you will also find it necessary to use it when you feel that your throat is drying up.
The same goes for the nostrils when you are in the house.
How does an air humidifier work?
Most devices generally work automatically. Its design gives it the ability to detect humidity levels in the ambient air and to raise it if the need arises.
The water in the tank will then be vaporized, which will mist the entire room in which the device is located.
You have to choose the location carefully, such as the center of the room.
Ultrasonic or steam air humidifier?
With the steam model, the water is evaporated and diffused throughout the room, usually through a radiator.
But many people today use ultrasound humidifiers.
The latter does not require the use of an additional device, which ensures better ergonomics.
It uses a specific plate that transforms water to spread it into space.
Why buy an air humidifier?
This type of device is mainly used to improve the health of people living in the house.
This is because it helps fight the germs and bacteria that cause colds and flu.
Air purification especially by an ultrasound model promotes the well-being of people suffering from respiratory disorders, sleep problems, regular coughs, and other illnesses.
It also lowers the temperature in a room in the case of hot weather or climate.
Where to place an air humidifier?
For this device to work optimally, find the right place for it should be of high importance.
Be aware first of all that it should not be installed near a wall or furniture. This would inhibit the broadcast range, making it less reliable.
To ensure the correct use of this device, remember to place it in the center of the room.
This will therefore optimize its efficiency. Be careful to avoid any obstacles, especially wooden ones, as moisture will quickly deteriorate them if they are too close.
To protect the health of your plants as well as yours, you should consider getting only the best humidifier for plants.
From the list above, we have selected 13 humidifiers that are certain to meet your needs or requirements.
These devices are each endowed with amazing features that will make your purchase worthwhile.
