Comments about Pure Guardian H4500 and H4600 Ultrasonic Humidifiers:

We use this unit in the bedroom. It is actually covers more area than we needed, but a previous unit made us caution to the larger to make sure of coverage. We use it on the lower setting and it does a wonderful job of humidifying the bedroom.

Quite heavy when tank is refilled.

Works as described. Produces humidity as you choose just by the turning of a dial. Easy to refill and maintain.

I bought the 4500 about a month ago. The primary reason I bought it was that it does not require replaceable filters. I found it is by far the quietest humidifier I have ever owned. However, if you are going to put out over a modest amount of moisture the machine has to be put on a pedestal to prevent the floor from becoming damaged by the moisture.

One of the first things we noticed was the air in our home was becoming cloudy (as seen through shafts of sunlight through the windows). Then there was fine white dust all over the house, upstairs and downstairs. The troubleshooting guide states the dust is caused by hard water. I have a water softening system installed so I don't have hard water. The guide also offers to sell you a decalcification filter that run from $20-$25 a piece (plus shipping) or recommends you use distilled water. Really, I have to buy water for my humidifier?

I am returning it. It still requires filters, which I have no idea how long they last, it requires a stand of some sort or it gets the floor wet, and it puts out a lot of dust that gets everywhere. It also drips a lot when you remove it from the bottom to refill it. Neat idea but still needs refinement.

I simply think this humidifier is GREAT

We are very pleased with the Pure Guardian H4600 Ultrasonic Humidifier we have it in a large room with cathedral ceilings, this same room also has a pellet stove which is very efficient but really dries the air out. Even though we have only had your unit for a short time we are very pleased and feel the output of the mist has really made a difference.

We are planning to purchase a bit smaller unit for our bedroom soon. Having said all this there is only one thing we found that has been a problem, the machine is easy to fill but heavy to carry when filled. It would be much easier if you could devise a way to fill the unit instead of having to carry it full. Also it really drips when you are carrying it to and from the water source, we carry a cookie sheet under it. The good really exceeds the bad but I would have to give it an above average rather than an excellent rating for that reason. Would definitely buy it again!

This is a very high quality humidifier. It's extremely quiet compared to other humidifiers that we've had. Easy to operate, and I like the low water light

Comments about Pure Guardian H4500 and H4600 Ultrasonic Humidifiers:

The Pure Guardian H4500 is extremely quiet and runs continuously for days on the low cool setting.
There are no added accessory costs and a big plus is the reduction of mold and mildew buildup.

Comments about Pure Guardian H4500 and H4600 Ultrasonic Humidifiers:

Mist is extremely fine and the unit is generally quiet. The night light is pretty bright and the little LED lights are too bright if one requires a dark sleeping environment. Warm or cool option is nice. One tank lasts a couple of days on low. Much better product than any others I have purchased.
