Frequently Asked Questions

Why should I use a humidifier?
People need a certain level of humidity to be comfortable. In the winter, indoor humidity can be extremely low, and the lack of humidity can dry out skin and mucous membranes. Low humidity makes the air feel colder than it actually is. Dry air can also dry out the wood in the walls and floors of our houses. As the drying wood shrinks, it can cause creaks in floors and cracks in drywall and plaster. Dry air also increases static electricity.

Does the product require regular cleaning?
Regular cleaning is recommended; approximately every 1–2 weeks (depending on use). When storing the unit, it is recommended to pour any excess water out and clean it with a soft, damp cloth. Let unit dry completely before storing.

Are there any wicks or evaporating pads to replace?
No. There are no wicks, pads or filters to clean or replace.

What is ultrasonic technology?
An ultrasonic humidifier uses a metal diaphragm vibrating at an ultrasonic frequency to create water droplets. Thanks to ultrasonic technology, the Guardian Technologies humidifier is virtually silent when running, making it easy to have on while you sleep.

What is Silver Clean technology and why is it used in your humidifier?
Unlike other humidifiers that grow slimy mold , the PureGuardian® Ultrasonic Humidifier uses Silver Clean™ technology embedded in the tank to fight the growth of mold and mildew on the surface of the water tank.

Where should I use the product?
It is recommended that you place the product up and not on the floor. Placing it on a table or nightstand during operation is suggested.


What size room will the humidifier work in?
Thanks to the adjustable spray feature, this humidifier works well in both large and small rooms.

What is a comfortable humidity level?
Forty to fifty-five percent (40&ndash55%) humidity is considered within the comfortable range. Any humidity level below thirty percent (30%) is considered dry.

How do I choose warm or cool humidification?
Choosing warm or cool humidification is based on your preference. Warm moisture tends to make the air in the room feel warmer due to the warm vapor being released into the air. In contrast, cool moisture generally has the opposite effect, causing the air to feel cooler.

Therefore, if you live in a warm climate, you may prefer a cool moisture humidifier, while those who live in colder climates may prefer a warm moisture humidifier.

Do I need to heat the water first if I want to have warm humidification?
No. It is recommended to put room temperature water into the tank for humidifying. The Guardian Technologies™ humidifier will heat and maintain the water temperature for warm humidification.

Do I need to put in a certain type of water for my humidifier to work?
You can use either distilled or regular tap water. If you have a high mineral content in your tap water, it may be preferable to use distilled water. Since distilled water is likely to contain lower mineral content than most tap water, it will prevent less build-up.

How long is the warranty?
The warranty is 3-years limited. For detailed warranty specifications please refer to the warranty section in the instruction manual.

Great humidifierReview by sgb73
I purchased several humidifiers this season, and this is by far the best one. A tank lasts longer than the others with similar capacity yet it is more effective (even though we have a very large bedroom). I used to own a larger model from pure guardian which stopped producing steam after 2/3 years, so we will see how long this one lasts but so far I highly recommend this model. (Posted on 5/29/2014)
Great product!Review by madeleine
This is a great product! We have been very happy with it. I just logged in to purchase another one for my parents. (Posted on 5/29/2014)
So far — greatReview by Readerease
Expensive yet appears after 30 days use to be worth the money. Quiet, efficient and easy to use, good product (Posted on 5/29/2014)
Excellent!Review by Grace Martinsen
I read many reviews before purchasing and felt I had picked the best product.
It has totally lived up to my expectation of excellence.
There are no filters or extra parts to buy as with other humidifiers.
The tank is easy to refill and light enough when it's full to where I can easily carry it.
After a month of nearly continuous use, I couldn't be happier with this product. (Posted on 5/29/2014)
Exactly what I was looking forReview by Jr621
This humidifier was exactly what I was looking for! I love that it gives you the option of having warm or cool mist. It's the perfect size to sit on top of your dresser or side table! It looks sleek and stylish and does not make a whole lot of noise. I keep mine in my bedroom and it works wonders when I'm sick. You just have to make sure to check the light that tells you when to refill the unit with water. I've gotten Guardian products before and have never had any issues with them. I highly recommend this product! (Posted on 5/29/2014)
