  • The Guardian Technologies™ PureGuardian® Ultrasonic Humidifier uses a metal diaphragm vibrating at an ultrasonic frequency to create water droplets that are expelled out into the room to help maintain the desired humidity level. An ultrasonic humidifier 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 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.

Good product

It is really good and not very expensive. The small size is very good for office and small bedroom, easy to be cleaned. The blue lamp inside is very beautiful too.

good humidifier, without bells or whistles

I bought this for my 8-year-old who was having nose bleeds due to the dry air. It is so simple and easy to refill that he can do it himself. It has on on/off button, that's it. Very streamlined, cute and easy to deal with. There is a light from somewhere inside which illuminates the blue dome. My son likes that, but it would bother me at night, so you should know that before you buy it. I love that it has no filter and the silver micron technology keeps germs at bay. However, the manual says not to put any oil in it and I would like to be able to add a few drops of essential oil, but perhaps that would affect the silver element?

Manual says it can run 8 hours, but it takes ours a little more than 24 to empty the tank. And it really has made a difference in the humidity level in our home. Think I might buy another one for my daughter, or another product from the same manufacturer.

Efficient, long life, TABLE TOP humidifier (not for an entire room).

I love my Germ Guardian. I had it for nearly three years before it stopped working. Turns out, you're not supposed to put essential oils in it. I'd recently (within 6 mos) started putting essential oils in it. Bad idea. This will kill your Germ Guardian.

I get horribly dry skin (eczema), eyes (contacts), and hair in the winter, as well as nosebleeds. The Germ Guardian improved all of these conditions.

Just use your common sense when purchasing this- this is a table top humidifier. It's good to humidify the area around the table top, it will not humidify the entire room, it will not change the humidity in the air. However, if you've got it on a night stand next to your bed, you'll definitely notice the great results.

Even when I got my tonsils out this past year, I directed my Germ Guardian at my face each and every night as close as I could and it just kept my throat moisturized which totally sped up and eased the healing process.

The blue light is nice, but yes, it is very bright. As someone who loved sleeping in pitch darkness, it took a while for me to get used to it, but I did. Now that my Germ Guardian is gone, my room is too dark!

It does last the full 8 hours, sometimes even longer.

My only complaint is that after a few months it began to have a loud start up. This would last for maybe 10 mins, but then it would quiet down to its normal, barely audible hum. Not a deal breaker for me, but it is the reason it got only 4 stars.

Like I said, this will not humidify an entire room, but if it's right next to you on a desk, or right next to the head of your bed or baby's crib, you will notice the physical results.

Just to note: I purchased this item through Amazon, but for the people who've had defective items, perhaps pay attention to the Amazon Seller who sold it you. You have to wonder how many different places it was shipped to before it got to you and what affect this could have on the product if it wasn't sold directly by Germ Guardian.

FURTHERMORE, and this is an IMPORTANT NOTE, everyone- Germ Guardian has a limited 3 year warranty on this product, you can go directly to their website to see for yourself and to register the warranty. Most warranties are barely one year, so Germ Guardian seems to be confident with their product, and from my experience with it, they've got reason to be. I recommend registering your Germ Guardian as soon as you get it, and for those of you who are hesitant after reading about the defective/used/short lived ones, as long as you register for the warranty and understand the terms of the warranty, you should have no problem getting a good one.

great for nursery

we had a vicks room humidifier from the grocery store that was really too large for our daughter's nursery and soaked the carpet around the unit. we bought this one because of size and the fact that is is germ and mildew free. we have been running it about a month with no mildew (unlike old humidifier that we had to scrub every day) and no soaking of room. our daughter has been croup free for over a month and I no longer worry about germs or mildew spewing in to the room from the humidifier like the old one.

This is a tiny humidifier! I bought it for my son as he suffers from bloody noses at night. We live in Arizona and it is very dry. We have the full size Germ Guardian on our side of the house and we like it but I thought the lights would bother the boys at night. So we ordered this. It puts out a small amount of steam and only lasts about 12 hours in our very dry house. But it seems to be enough for my boys. The unit does get warm and doesn't turn itself off when empty. It has a light inside which makes the unit glow a very pretty blue which is a great night light.

Small and easy to maintain

I have owned the Pure Guardian TableTop humidifier for many years and use it in a small nursery when the grandchildren visit. It is very simple to use and to keep clean - in all the years I've owned it, there has never been any build-up of mold or scum, and there are no filters to buy. I recently purchased one for my Mom because it is easy to fill. She has arthritis and would not be able to handle a larger tank. Yes - it needs to be filled more often, but she USES this one because she can handle it!

Great little humidifier

I love this humidifier. It is quiet, stays clean a long time and is perfect for the bedroom or any small room.

By: Dan Pitt

Great Purchase

Great Buy at a great price, it works for a small area and last 8-10 hours and easy to use.

By: Sheryl Stoler

Best humidifier around.

Humidifier is quiet and doesn't require a lot of cleaning. You don't have to worry about mold or mildew. I own a few of them and now my children use them in their homes.

By: Dr. William R. Nirote

No filter and quiet!

Having had several humidifiers, the plus of this one are three-fold. It is easy to clean. There is no filter to clean/replace. It is quiet compared to others with motors/blowers.

This is just what I needed for dry winter weather. My sinuses are always so dry in the weather and this humidifier is just right.

By: inochka

great compact humidifier

It takes little space but works for even large rooms. I felt its effect when we were all sick and it helped us breath thru the night. Its great for Florida residents and for other humid climates, mold doesn't grow on this model.

By: LD-L

Great little impact!

I've had another Pure Guardian humidifier that I've been very happy with. I love that there's no filters to change. It works really well. I was surprised that I didn't need to fill it up each night. It's perfect for when our granddaughter spends the weekend as well as for the guest room. This little gem is great!

By: daijsmith

Works great on my nightstand!

I use this every time my boys or I have a cold. I set it up on the nightstands beside our respective bed and it really makes a difference.
If you are buying this to humidify an entire room, you'll be disappointed. If you're buying this as a tabletop humidifier you intend to keep close to you, you'll be happy with it! We have had ours for over a year now and it has done wonders for my sinuses and my children when they have coughs and congestion.
