FAQs

FAQs

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 your skin and mucous membranes. Low humidity also 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?
It is recommended to wipe out the water tank and base of the product on a regular basis; approximately every 1–2 weeks (depending on use). The Guardian Technologies™ PureGuardian® Ultrasonic Humidifier has Silver Clean™ technology in the water tank, which helps to fight the growth of mold and mildew on the surface of the water tank.

When storing the unit, it is recommended to pour any excess water out and clean it with a soft, damp cloth. Let dry completely before storing.

Are there any wicks or evaporating pads to replace?
There are no wicks or pads to 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?
Silver Clean™ technology is small particles of silver 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 on a table or nightstand and not on the floor.

What is a comfortable humidity level?
Forty to fifty-five percent (40–55%) humidity is considered within the comfortable range. Any humidity level below thirty percent (30%) is considered dry.

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.

A great five-cent cigarReview by Bliss
Rating
This humidifier does an awesome job, is easy to operate, doesn't collect mold, fits nicely on any tabletop, and raises the humidity in my gas-heated home by several degrees. And it's priced right! I have purchased two of these; one for the bedroom and one for the living room and couldn't be more pleased. I've tried several others in the past but none can compare to this one. I highly recommend it. (Posted on 5/29/2014)
Quiet, effective, simpleReview by Kimball
Rating
My daughter is asthmatic, and we've been through several (4-5) different humidifiers over the last few years to help keep it in control. We've owned this one for quite some time now, and it has been great for us for several reasons:

1) My 6 year old is able to fill it up each night all by herself.
2) The water reservoir really does stay clean
3) Does not easily spill in a young, active child's room. (Posted on 5/29/2014)
Wonderful little machine! With antibacterial silver to bootReview by chelput
Rating
I love this little machine. It's quiet! It runs at various levels for use a 4 hour 6 hour and 10 hour setting. It also has a nightlight! This sits next to my bed every night. I have a humidity monitor as well to figure out what range to place it on.
I used it when I was sick placing menthol and peppermint air mist liquid in it.
It stopped my bloody noses.
I bought this for my father and younger cousins.
The antibacterial silver is amazing!
Also there is no pooling of water it's all vapor
So clean quiet and wonderful

Con - yes you do have to fill it every night but it's great for saving space (Posted on 5/29/2014)
Wonderful for the bedroomReview by B. Milberry

I love this little humidifier. It's perfect for my bedroom at night during the dry winter months. Lasts me all night and simple to refill. You can turn the light on and off. The ONLY thing I wish is that you could have the light stay on but not change color. But I highly recommend this. I'm buying a second one for my Mother's room. It's very quiet. (Posted on 5/29/2014)

Perfect for bedside!Review by Dawn Soponski
Rating
I got the first unit with relatively low expectations, thinking this would be fun for my son to have in his bedroom since it lights up as well. I was shocked at how easy it is to maintain and how long it has lasted!! It worked so well that I have since bought two additional units for our other bedrooms. On the low setting it does last the full 10hrs advertised. On the high setting it lasts at least 5hrs. My son loves filling these every night before bed, and it has replaced his nightlight, too :) With reasonable expectations this product is simple, effective and well worth the low price point vs comparable units. We've used this humidifier nightly for over a year and I'm very pleased. (Posted on 5/29/2014)

Effective and easy to useReview by Mr. Walker
Rating
We have been using this for a couple months. It is easy to fill and operate, and easy to clean. It is very quiet. The light changes color when that function is on, but we usually leave the light off. I can tell that the humidity helps our skin and breathing to be less dry this winter.

Overall it is compact, convenient, easy to use and fill, and decreases dryness. (Posted on 5/29/2014)
A quiet, effective humidifierReview by C. Scrivo "cms1230"

We were looking for a humidifier to use in the bedroom. The old one was so loud that it woke us up!
This model was surprising, because it sits on the night table, it's small, but it's virtually silent, and throws out
enough vapor to be very effective. And lasts all night. A great and inexpensive product. (Posted on 5/29/2014)

quiet, efficient, no filters!Review by mermaid babe
Rating
We use this in our apartment and it works great in both the large living room and bedroom. It's quiet and there are no filters to worry about. Very satisfied. This is the second winter using it. I don't think it mentions it in the description, but the night light changes colors...great for kids and cool adults :-) with this humidifier on, our hygrometer has no problem getting in to the comfort zone.

Perfect for overnightReview by Laura L. (CO)
Rating
I've owned numerous humidifiers over the years and always end up ditching them due to high-maintenance cleaning, mold, and causing me to develop a nagging cough. I've had none of these issues with the ultrasonic and in fact just bought a second one for my son's nursery.

The reservoir essentially only holds enough water to run while you're sleeping. This is perfect - just set it out to dry out during the day and fill it up again at night and you'll never have a mold issue.

There are four different settings for mist level and night light (which I find annoying but may be good for a child.) Mine sits right next to the bed. I would not advise this little machine for a large room - but it's perfect for smaller rooms, especially if you set it up near where you are sleeping.

The only negative: the second humidifier I purchased (same exact model) runs for more like 7 hours before it runs out of water. Not sure why this is happening. But for me the positives of this little machine outweigh the negatives. (Posted on 5/29/2014)

Best small one u can findReview by Kittylovescats
Rating
When I first received the humidifier, it did not work at all. I was going to send it back,but decided to give it another try. So, I refilled it and pushed the on button real hard, several times, and it started to work. So far it's been working for about three weeks. It also is VERY quiet. (Posted on 5/29/2014)
