Best Plant Humidifier Australia – Buyers Guide

If you are keen to learn more about plant humidifiers (1) and want to know what to look for when you purchase one, we have all the information you need in our guide below.

Understanding the Benefits

Plant humidifiers offer a wide range of benefits to your plants and your environment. From reducing bacteria and viruses by increasing the humidity in the air to helping plants heal when they have been struggling to thrive. In addition, increasing the moisture in the air will help your plants to grow well as it will create a warmer environment. 

Different Humidifier Types

There are a number of different options to choose from when picking a humidifier, however,  warm mist or cold mist are the two main models to choose from. Warm mist humidifiers help you to keep a constant level of humidity but they are often expensive to buy. Cold mist humidifiers are cheaper but they can be noisier too.

Looking After Your Humidifier

Anyone looking to invest in a humidifier needs to be prepared to clean their device on a regular basis! To keep your humidifier in the best condition, it is always wise to use distilled water instead of tap water and schedule a weekly clean of the unit.

Some humidifiers can be washed and sterilised in the dishwasher but if yours can’t then cleaning it thoroughly with bleach will help to kill off any bacteria that has grown.

Knowing When to Use Your Humidifier

Humidifiers should never be used in an environment that already has high humidity levels. If you don’t have any way of measuring the humidity, a good indicator is to check if there is any condensation or wetness on the walls or windows – if there is then the air is already humid enough.

In addition, never use a humidifier that has had water left in it or one that has not been cleaned. Ignoring these basic rules can cause damage to your plants.

Don’t Forget Your Outdoor Plants

Many people think that their cute plant humidifier is only good for indoor use but there are models that are perfect for outside. Humidifiers outside help to replenish moisture around your plants in areas that are very dry. However, take your time to find the right model as your standard indoor model won’t be much use to outside plants.

Frequently Asked Questions – Finding a Good Plant Humidifier

Humidifiers come in all shapes and sizes and you can expect to pay less for a small plant humidifier that you use indoors than a more powerful model for outdoor use. However, finding the cheapest option possible may not be the right way to go. Rather than basing your purchase on price alone, take the time to check the features and opt for a model that offers the support you need.

Typically, indoor humidifiers come in a range of shapes and sizes, helping you to find the right fit for your indoor plant collection, including electrical options. Outdoor humidifiers are less complex and can be anything from a tray of water that evaporates around your plants to a large pump action bottle that creates a mist.
