Humidifiers create pleasant conditions indoors by increasing the moisture level during cold or dry weather, but they are usually noisy devices. The best humidifier can produce the desired effect and do so quietly.

The Honeywell QuietCare Humidifier HCM-6009 has a noise level that is as much as 30 percent lower than similar models. Using a humidifier is often a matter of necessity to keep your skin and delicate membranes moist, and it is an option that can protect your furniture and your piano. Knowing what to look for can help you conduct a meaningful humidifier review.

Key Features of Honeywell Quietcare HCM-6009

Features on a humidifier can make you either love it or hate it, and assessing your preferences gives you a guide to selecting the best humidifier. In addition to noise control, the qualities that are often used for comparison include the presence of adjustable controls and multiple output settings, cleanliness, portability and tank capacity.

Controls and Settings

Adjustable humidity controls and multiple output settings are important features that let you regulate a humidifier so that it works the way that you want it to.

A humidifier that can adjust for moisture levels allows you to achieve the recommended average of 35 to 45 percent relative humidity. Multiple settings for output let you increase or decrease the amount of moisture in the air. The Honeywell QuietCare humidifier lets you customize the moisture output with adjustable controls and multiple settings.


The Honeywell unit uses an antimicrobial cleaning cartridge that helps produce moist air that is clean and fresh. It inhibits the formation of mold and bacteria that can cause odors, and it prevents slime from accumulating in a humidifier.

At a weight of less than 20 pounds, the humidifier is easy to move. The unit is designed to provide moisture to large spaces on one floor of a home when certain conditions are met.

The total coverage area must not exceed 1900 square feet, and doors must remain completely open to allow the flow of air from room to room. Furnishings and decorations that block the path of moist air tend to limit the effectiveness of the unit.

Homes that comply with the requirements for insulation as recommended by the American National Standards Institute (ANSI) are likely to get good results from the unit when other specifications are met.

When locating the humidifier, you need to place it on a surface that is not wood or ceramic to limit sounds that may result from vibration.

Tank Capacity

One of the most important features to look for when you conduct a humidifier review is the capacity of a unit to hold a supply of water. The Honeywell QuietCare model has dual tanks that make carrying and filling it an easy task.

Cleaning the tanks is convenient with a configuration that allows ample access to the interior, but they are slippery when slime forms on the walls. The unit can run for an entire day, depending on the humidity level that you select from three moisture settings.

It has a capacity of 3.4 gallons and can output nine gallons per day, but you need to refill the tanks to disburse that much moisture.

The Bottomline

Honeywell is certainly a name that is well reputed for producing some of the best-selling air purifier models. That alone offers strong enough reason for some to select the Honeywell Quietcare HCM-6009 in place of lesser known (not necessarily inferior) alternatives like Air-O-Swiss Ultrasonic Humdiifier.

One feature that makes this a worthy consideration is its customizable moisture setting and extra low noise operation. Last but not least, price may be a major determinant as it cost lower than its peers. But be mindful that compared to Roolen Smart Ultrasonic Humidifier, the look of Honeywell HCM-6009 makes you feel like running a ‘Pentium’ machine in today’s computing world.
