The PureGuardian® 90-Hour* Ultrasonic Humidifier guards against problems caused by dry air in the home, making life pleasant for those with cold, flu, allergies and dry skin.

A sensor monitors the humidity level in the room and adjusts accordingly to maintain a consistent humidity level. Unlike other humidifiers that grow slimy mold on the water tank surface, the 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. Thanks to ultrasonic technology, it is ultra-quiet when it runs making it ideal to have on while you sleep. The H7550 PureGuardian® Humidifier is equipped with the option for warm or cool mist, and a low water indicator light lets you know when it’s time to refill the water tank. The tank capacity is 1.32 gallons, and it runs continuously for up to 90-hours*. A timer allows you to customize the desired run time for up to 12-hours. This humidifier also features a soft glow night light that turns on and off and easy-to-use digital controls.

This ultra-modern, sleek new design was developed with you in mind. Order your PureGuardian® Ultrasonic Humidifier today!

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?
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 dry completely before storing.

Are there any wicks or evaporating pads to replace?
No. 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, allowing you to keep it on while you sleep.

What is Silver Clean™ technology, and why is it used in your humidifier?
Unlike other humidifiers that grow slimy mold and mildew, the Guardian Technologies™ PureGuardian® 144-Hour Ultrasonic Digital 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.

*DO NOT PLACE UNIT DIRECTLY ON CARPET, TOWELS, BLANKETS OR OTHER ABSORBENT SURFACES.

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.

GreatReview by Margaret M. Gibson "nutmeg3748"

I've tried a couple of different humidifiers, several Vick's and one Crane that are cheaper. I bought these for $130. I wouldn't pay $180 as the catalogue offers advertise. It's not over twice as effective as the large Vicks. However, I believe this is the best because of the feature automatically adjusting output with the selected humidity level. It works. I have another humidity monitor and they're both at the same level, plus or minus a couple of percentage points. I think it's fairly accurate.

The drawbacks are the convoluted control buttons and lack of directional steam top. Reading the manual to adjust the night light and all of that solves the problem, but what a pain. And then a little simple mcgyvering with some tape solves the directional problem. I bought another one of these for my office at work. When I buy something again, it's a solid product.

Being a resident of NJ, the air inside your apartment or home can become extremely dry. Like 28% humidity dry.
This product arrived yesterday and was plugged in right away with the hopes that it would provide a much needed good nights rest.
Whalla! I feel so much better this morning, that I felt compelled to right this review. I like this product so much and it has provided such immediate results, that I am ordering another one today. Considering how loud other humidifiers can be, this is a dream. It is very quite. The gurgling noise someone wrote about is not offensive to me. The warm mist setting is an excellent feature.
I highly recommend this product! (Posted on 5/29/2014)

This product has given me good service. I have been running it practically non-stop for a week. It has nicely helped me in my important work of devotional service to Lord Sri Krishna, the Supreme Personality of Godhead. (Posted on 5/29/2014)
Best Humidifier!!Review by Grandma Peachie

The BEST humidifier I have ever had. Found that using Distilled water works the best -- no residue at all. We have extremely hard water and even with a water softener -- it would destroy previous machines. Went to this one based on the ratings we saw and started right off with distilled water. Wonderful and I'm sure will last us for years to come! (Posted on 5/29/2014)

I love how much control the different settings give you. I had a previous model which I used for years but decided to upgrade. Glad I did. Once you get the hang of filling it up, it's a winner. (Posted on 5/29/2014)
