Thanks to ultrasonic technology it is virtually silent when operating.

  • 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 (40-55%) 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.

Love, love, love!

I absolutely love this little humidifier! I get bloody noses every fall/winter when we turn our furnace on. I was looking for something without a filter that I would have to change every year. I really cannot believe I lived so long with my other humidifier. It was so loud, and the filters were really expensive. This little guy is so quiet, the only thing I ever hear is the glug of the water every now and then. I even had a friend over to visit, and the first thing she said when she walked in was how nice the air was in my house. She was so impressed with this unit, she asked me to text her a link so she could buy one. She's still talking about it 4 days later!

Lost a part to my humidifier similar to this, but the replacement wasn't online. I contacted the company and within a couple of hours they emailed me back saying it was retired but they'd keep an eye out for one that came in used. Again, the same day within another couple of hours they emailed me saying they found one! Sent it to me for free because it was used. I am a customer for life! One of the best customer service experiences I've had!

A woman's perspective

This is an attractive unit. I heat with a gas stove and it gets extremely dry in my living room. This little unit has been running non stop since a purchased it. It's quiet, fits on a small table and, as I said, is not unpleasing to the eye. I especially enjoy that it starts right up and the steam is visible. My house plants send their thanks along as well. The only reason I didn't give it a five star rating is the awkward manner of refill. It doesn't sit flat in the sink so I have to hold it to have it fit under my facet. It is heavy to care for an older person (66) and doesn't slid into place easily because of the weight. Why can't you make this wonder product with the refill cap on the top so I could carry a container of water to it? All in all, I love this. Best humidifier I ever had. In fact, I have the bigger model in my bedroom. This was my second purchase and I intend to purchase more as needed.

Love the humidifier

I bought this humidifier about 2 years ago. It is awesome! I use it for my baby and I'm so happy I spent money on this humidifier. It has a choice for warm or cold mist, I can't find that anywhere else. I had one issue with it and they replaced it free of charge! Amazing product!

Great product and early delivery

Product was exactly what we wanted and works great. Arrived ahead of schedule which was a bonus.

Works great, low maintenance, but.....

I love this product, it is the easiest humidifier to maintain that I have ever owned. However, I am finding that regardless of how far away I set it up from the smoke detectors in my home, it eventually sets them off. I have had to completely discontinue my use of the product and I am considering returning it if the store will take it back. I am disappointed that I will have to buy another brand/model after doing a lot of research and finding this great little model. The strange thing is that I have struggled to find others online that have had the same experience. I have moved the humidifier into multiple rooms (2 bedrooms and a living room) and I have had the same result after running the humidifier in that room for as little as a half an hour. The room does not appear foggy in any way, and I have the decalcification filter installed.

Tank needs redesign.

Unit seems to work very well. Tank is awkward to handle when refilling and a concern is possible damage to the humidity spout when placing tank in kitchen sink. Full tank at full 'throttle' (warm) is good for maybe 10 hours.

One thing that will help a lot is to purchase the replacement filters and change them every year. I always keep a spare.

Great humidifier

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.

Great product!

This is a great product! We have been very happy with it. I just logged in to purchase another one for my parents.

By: Readerease

So far — great

Expensive yet appears after 30 days use to be worth the money. Quiet, efficient and easy to use, good product

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.

Exactly what I was looking for

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!
