Humidifiers Buying Guide

When the temperatures start to drop and the air starts to get drier – this is when you should start thinking about getting your hands on a humidifier. Whether you’ve caught the season’s flu or itching from dry skin, this appliance can help relieve a number of cold and flu symptoms, as well as physical discomforts. While humidifiers are most commonly brought out during the cooler, winter months, the air conditioning can take its toll on your skin and immune system in the Aussie summer as well. Read on for a full buying guide on the different types of humidifiers and where you can buy one in Australia.

What are humidifiers?

What do they do? how do they work?

A humidifier is a device that helps to maintain moisture in a room or in the entire home. There are three main types of humidifiers that are available in Australia:

  • Evaporative Cool-Mist humidifiers: use a fan to force dry air through a wet wick filter and water evaporates into the air.
    • Pros: generally don’t emit bacteria into the air and uses little electricity
    • Cons: noisier and require changing of filters every few months (depending on how often you use it)
  • Ultrasonic Cool-Mist humidifiers: use a small metal diaphragm that vibrates, converting the water into a fine vapour (without a filter). These can sometimes leave a white powder around the unit due to dissolved minerals in hard water but it’s not harmful and can be minimised by using distilled water. These are suggested for warm/dry areas.
    • Pros: quiet and uses less electricity
    • Cons: can omit bacteria into the air so it requires frequent cleaning (daily cleaning if you use it often)
  • Warm-mist humidifiers: heat water to boiling temperature and then mix the steam with the air. These are suggested for use in cool/dry areas as they can make the room a little warmer.
    • Pros: quiet and don’t have filters to replace (although some come with an absorption pad to collect mineral deposits, which do require changing)
    • Cons: use more electricity than cool mist humidifiers and can pose a risk of burns as the water in the unit is hot and thus, not suggested to use around children

Humidifier Vs Vaporiser

Humidifier Vs Vaporiser

In essence, vaporisers perform the same basic function as warm mist humidifiers, but these units also heat and evaporate medicine. A vaporiser is ideal for adding warmth to a room during winter. It can also be waterless and use pre-moistened pads, usually infused with particular oils or menthol as medicinal remedies.

Humidifier Vs Dehumidifier

A dehumidifier does the opposite of a humidifier – it removes excess moisture in your home. Both can improve air quality, as well as assist with chest congestion and asthma. However, if your home is too humid, opt for a dehumidifier as it can help reduce mould and mildew build-up.

Why buy a humidifier?

Humidifiers have come a long way since they first hit the market, becoming quitter, as well as easier to use and maintain. Benefits include:

  • Assisting to relieve colds, asthma and allergy symptoms
  • Reduces static electricity in the air so you don’t get a static shock when you sit on the couch
  • Helps sooth dry or itchy skin
  • Snoring partner? Helps ease intensity of the snoring sound
  • Retains heat inside the home with moist air, which can also reduce electricity costs from heating
  • Helps to protect wooden floors, furniture and musical instruments from cracking

Humidifiers for a baby

Humidifiers for a baby

A humidifier can also be found in a newborn’s nursery. As a baby is more prone to congestion and has skin that’s sensitive to dry climates, a humidifier can help add the moisture back into the air. There are certain precautions that should be considered when buying a humidifier for a child’s room, including burns that could occur with a warm-mist humidifier and the regular cleaning required to prevent mould and bacteria growth.

What size humidifier do you need?

Depending on the size of coverage you require, there are three main sizes of humidifiers to choose from:

  • Portable humidifier: cheapest of the range, ideal for single rooms or travel.
  • Room humidifier: usually portable but heavier to move around. It’s designed for medium to large sized areas.
  • Whole house humidifier: works with your home’s main cooling and heating system. It connects directly to the water line, not requiring any refilling.

It’s important to consider the size of the room you’re aiming to cover. If the humidifier covers a space larger than the room itself, it can leave too much moisture and condensation on windows, increasing the chance of mould. However, if there’s not enough humidity, it can also allow for dry air to damage furniture. Most humidifier manufacturers specify a square metre coverage range of the product, which you should look out for before making your purchase.

Features to look for in a humidifier

  • Low noise levels (generally humidifiers sit under 45dB, which is as quite as a human whisper)
  • Safety features to reduce mould and bacteria build up
  • Design for easy maintenance without hard to reach areas that you’d struggle cleaning
  • Digital controls and user friendliness
  • Easy to refill tank and carry tank
  • Convenience features such as auto shut off when water is emptied (with evaporative cool-mist models you want them to continue running to help the filter dry out, reducing the chance of bacteria growth)

How much do humidifiers cost?

In Australia, most humidifiers cost between $80 and $300, increasing in price with the additional range it covers. While most humidifiers max out at the $300 mark, the Dyson AM10 Humidifier sits at around $799, being at the high end of humidifiers with its sleek design.

Room coverage Price
<25m² $80 – $150
>25m² $150 – $300

Should I buy a humidifier?

While there are a number of benefits that come with a humidifier, there are also a number of aspects to consider before making the purchase. One of the main downsides of humidifiers is the regular cleaning required to ensure no growth of bacteria or mould. Certain models, such as the evaporative cool-mist humidifiers, also use filters and demineralisation cartridges that require replacing. It would be wise to factor in how often you’ll use the machine and the additional cost you’d incur from replacing these.

Humidifiers are claimed to relieve the downsides of dry air – congestion, sore throats and dry skin. They aim to weigh down dust and allergens, making it difficult for viruses to survive. They’re especially useful during the winter months and you’d hardly notice them in a room, with low noise levels. As there is a wide range available, look at how much moisture the humidifier pumps out, as well as the area it covers before jumping into a purchase decision.
