Honeywell QuietCareâ„¢ HCM-631 3 Gallon Humidifier

Pros: Very quiet operation, compact size, easy to clean
Cons: Water tank cannot stand by itself when inverted for filling or cleaning.

Unlike our previous humidifier, the Honeywell HCM-631 is very quiet. The water tank, which holds 5 quarts, will last up to 14 hours with the humidistat set on maximum and the fan speed control set on high. Since my husband and I only use the humidifier in our bedroom while we are sleeping, the water tank capacity is sufficient for our needs.

OUTPUT CAPACITY
The manufacturer claim of 3 US gallons output per day can only be satisfied if you fill the 5-quart water tank twice in a 24 hour period.

WATER TANK
Due to the curved top design, the water tank cannot stand by itself when inverted for filling or cleaning. I found a way to prop up the water tank in the corner of my laundry sink so it could be cleaned following manufacturer instructions, but a flat top would make it easier.

DECISION CRITERIA
This humidifier met four personal requirements:
1. quiet operation
2. a water tank that wouldn't be too heavy to lift when full
3. output for at least 8 hours without refilling
4. ease in cleaning

Pros: Quiet. Air Washing Technology is antimicrobial. Size. Ease of filling tank.
Cons: Cold air may be bothersome. This unit blows cold air for quite a distance.

Don't let the size of this humidifier fool you. Like it states on the box this humidifier easily hydrates 1,000 sq. ft.

Very Quiet. I am a light sleeper and am able to run this humidifier at night and sleep soundly.

When I initially turned this unit on my kids were standing in front of it, felt the cold air and walked approximately 12 feet away from humidifier and were amazed that they could still feel the cold air. The cold air may be bothersome to some, for us not a problem.

For a household with allergy sufferers this unit is ideal and was recommended by our allergist. It features a Pro-tec water purifying ball that you install in water tank. Has Air washing technology that traps dust,pet dander, pollen, odors, and is antimicrobial.
