What does a humidifier do?

The ideal level of humidity inside a home is considered to be between 30% and 50%. Humidifiers and dehumidifiers can work to help your home achieve this level. While dehumidifiers work by removing moisture from the air, humidifiers add moisture to the air in dry environments.

Generally, air is drier during winter months and indoor heaters further strip the air of moisture. This can cause timber homes and furniture to warp and even crack. Dry air can also be damaging to your health.

What types are available?

There are two main types of humidifiers: evaporative and ultrasonic. Both styles can effectively add moisture to your home or office but they use different methods to do so.

How to compare humidifiers?

The first step in choosing a humidifier is determining what size you need. Common sizes include tabletop or individual room models, console units and central air humidifiers.

The price of a humidifier depends on size, type and features. Tabletop humidifiers typically cost between $30 to $200, whereas console humidifiers run from $100 to $300. Central air or whole house models start at around $150 and require an additional installation cost. Keep in mind, larger units also use more electricity and will increase your monthly electric bill.

How to clean a humidifier

The main thing you can do to extend the life of your humidifier is to keep it clean. Regular cleaning also prevents mould and helps keep your air safe to breathe. Look for a model with an easy to remove water container. Generally, a humidifier that is used daily should be cleaned at least weekly. When cleaning, it’s important to drain, rinse and fully dry the dehumidifier to prevent mould and other undesirable build-up. The specific instructions to clean each model depends on the manufacturer.
