Benefits of a Humidifier

Humidifiers are great devices that can improve your quality of life. How? Prolonged use of a humidifier may provide benefits such as:

What to Look for in a Humidifier

Coverage

Consider the size of your space and ensure that the unit's coverage area matches your needs. Keep in mind that the more extensive the coverage, the more expensive the unit will likely be.

Capacity

Larger capacity humidifiers mean fewer trips to refill the reservoir. This doesn't matter if you live in a smaller space where a water source is only a few steps away. However, if you occupy a larger space, a larger water tank may help.

Size

Be sure to consider what size would interact with your space the best. The last thing you want is trip over a humidifier that’s simply too large.

FAQs About Humidifiers


Is it good to sleep with a humidifier?

Humidifiers can be beneficial for anyone, including those that live in drier climates, suffer from allergies, struggle with snoring or simply desire better air quality during the night. Several humidifiers offer additional features like essential oil diffusion and air filtration that can help tremendously for sleep.

Which is better: cool or warm mist humidifier?

Since both are highly effective at delivering humidity, the choice comes down to personal preference. Those who like to utilize aromatherapy tend to opt for warm mist humidifiers as they do a better job at dispersion.

What type of humidifier is best for winter?

The best humidifiers for all weather conditions operate using ultrasonic technology. These units are efficient at processing warm and cold air and producing a consistent stream of mist.

Where should a humidifier be placed in a bedroom?

Although humidifiers can be placed in various locations, it is important to avoid putting them in corners or flush with a wall. Doing so can drastically reduce the life of your humidifier and even result in overheating and possible damage to the space. The ideal location is on a table or nightstand.
