              How To Choose The Best Small Humidifier For Plants?


              Humidifiers come in all different sizes, so it's important to choose one that's the right size for your needs.

              If you only want to humidify a small space like a single room, then you can get away with a smaller humidifier. But if you want to humidify a larger space, like an entire house, then you'll need a larger one.

              To figure out the right size humidifier for your needs, think about the square footage of the space you want to humidity.

              A good rule of thumb is that you'll need about 1 gallon of water per day for every 100 square feet of space. So if you want to humidify a 200 square foot room, you'll need a 2-gallon humidifier.

              Type Of Humidifier

              Humidifiers are divided into 2 major types: cool mist and warm mist.

              Cool mist humidifiers create a fine mist using ultrasonic technology.

              Warm mist humidifiers heat the water using heating elements to create steam, then release it to the air.

              When it comes to plant humidifiers, warm mist humidifiers are generally not recommended as they can raise the temperature of the soil, which can be detrimental to plants.

              Cool mist humidifiers, on the other hand, are a great option as they can help increase the humidity around your plants without raising the soil temperature.

              Run Time

              One of the most important things to consider is run time.

              This is because you want to make sure that your humidifier will be able to run for long enough to effectively increase the humidity around your plants.

              If you have a small space, such as a single room, then you will likely only need a humidifier with a short run time.

              However, if you have a larger space, such as an entire house, then you will need a humidifier with a longer run time in order to be effective.

              Moisturizing Speed

              The speed at which a humidifier can add moisture to the air can be an important factor, especially if you have plants that require high humidity levels.

              There are a few things to keep in mind when choosing a humidifier with the right moisturizing speed.

              Consider the size of the room you'll be using it in. A smaller space will require a lower output humidifier, while a larger area will need a higher output model.

              Think about how often you'll be using the humidifier. If you only need it occasionally, a lower output model will suffice. However, if you plan on using it daily or for long periods of time, you'll need a higher output model that can keep up with the demand.

              Take into account the type of plants you have. If they're delicate and require high humidity levels, look for a humidifier with a higher output. Conversely, if you have tough, low-maintenance plants, a lower output model will do the trick.

              No matter what your needs are, there's sure to be a small humidifier out there that's perfect for your home and your plants!

              Will a small humidifier work for plants?

              Yes, it will. A small humidifier will add more moisture, which is beneficial for indoor plants.

              How do I know if my plants need a humidifier?

              To know if your indoor plants need a humidifier, check these signs:

              • Do your plants have brown spots?
              • Are the edges of their leaves brown?
              • Are their leaves dried and dehydrated?
              • Does your plant have dropping or wilting leaves?

              If they have any of these signs, consider buying a small humidifier for them.

              What size humidifier do I need for my plants?

              If your indoor plants are in your living space, then the best humidity ranges are from 50-60%.

              If the room is larger than 500 sq. ft., you should opt for a large sized humidifier.

              399-499 square feet of room area, pick a medium sized model.

              Under 300 square feet, choose a small sized model.

              Can I use tap water as a humidifier for plants?

              No, you can’t. You shouldn’t use tap water as a humidifier for your indoor plants because tap water contains minerals and bacteria that are harmful for plants.

              Do plants need a cool or warm humidifier?

              While you can use both a cool and warm humidifier for indoor plants, it’s recommended using a cool model. The reason is warm humidifiers can increase the ambient air temperature—which is unnecessary for indoor plants.


              When it comes to keeping your indoor plants happy and healthy, there are many great small humidifiers on the market. We have highlighted our favorite options above. They’re the best of the best out there, so you will be able to find the best small humidifier for plants.

              Whatever size or style you choose, investing in a humidifier is sure to give your beloved houseplants the moisture they need while never taking up too much valuable free space.
