So, What Exactly Does a Humidifier Do?

Humidification is simply, the addition of water into air. Most people require a certain amount of ambient moisture in the air that is not too high and not too low in order to be comfortable.

By increasing the moisture in the air of your home, it provides a more comfortable environment, which makes it easier to breathe and sleep.

And Why do I Need One?

There are several reasons why you should use a humidifier, including the betterment of your health, help with skin and help with the upkeep of your homes wood — just to name a few!

Did You Know?

Humidified air can relieve the discomfort of colds and flu.

Proper humidity levels help to reduce the number of nosebleeds some people are prone to in the dry, winter months.

During the dry, winter months, keeping humidity levels up in the home (between 40–50%) makes the air feel warmer. This can mean you'll run your heat a bit less and save money on your bills!

Why Ultrasonic?

  • Ultrasonic Humidifiers produce mist by using a metal diaphragm vibrating at high frequency.
  • The water molecules that are produced are extremely small, about one micron in diameter.
  • The mist is almost immediately absorbed into the air.
  • Because this type of humidifier does not use a fan, it is very quiet when operating.

Short lifespan. Broke after normal use.
4 Stars
Short lifespan. Broke after normal use.
UPDATE: PureGuardian replaced free of charge and it wasn’t a hassle. New humidifier has been working well.UPDATE: It broke already! The button completely broke off after normal pressing of it.——-I had been struggling with mold build up with my Crane teardrop humidifier despite cleaning it regularly, and the Crane was a pain to clean because of the design. I decided to try this because of the silver clean technology, and I have found that it does indeed help prevent mold build up. It is also much easier to clean than the Crane. I use tap water in the tank. I do preventative cleaning monthly by shaking a few tablespoons of white vinegar into the tank and letting it soak for about an hour, then using the little brush supplied to clean around the base. So far, no mold! I have been using this in my bedroom daily with no operating issues.
