Quiet Comfort Cool Moisture Humidifier

The Honeywell Quietcare Cool Moisture Humidifier is efficient in establishing a clean breathing environment. This cool moisture humidifier utilizes QuietCare Technology that's 30% quieter than similarly constructed evaporative humidifiers. Discharging invisible cool moisture into the air in 3 moisture output settings, the Honeywell Quietcare Cool Moisture Humidifier features a run time of 24 hours per filling. Accessibility has also been addressed with the utilization of a wide tank opening that allows for easy filling and cleaning. An ideal fit for medium sized rooms, this Honeywell humidifier provides premier performance and accessibility.

Genuine Honeywell Wicking Filter A

This cool moisture humidifier works with Honeywell Replacement Filter A. Designed for optimal moisture output and inhibiting up to 99.99% of mold growth on the filter, this Genuine Honeywell Humidifier Wicking Filter captures minerals from the water and helps prevent the buildup of white dust. The updated version of the Honeywell Replacement Filter A features a blue pre-filter layer that helps capture large airborne particles from the air that passes through the filter.

Protec Antimicrobial Cleaning Cartridge

The Honeywell Quietcare Cool Moisture Humidifier can also use Protec Humidifier Cleaning Balls. Protec Antimicrobial Cleaning Cartridges feature a patented antimicrobial, Aquastat that continuously works to hinder the growth of bacteria and mold. They're also capable of preventing the buildup of slime in the water and humidifier surfaces. Protec Antimicrobial Cleaning Cartridges work in all humidifiers and are safe/non-toxic. Aquastat contains no harsh chemicals or harsh acids making the cleaning action just as gentle as water on your humidifier surfaces and components.

Helps Temporarily Relieve Dry Air Discomforts

  • Provides an efficient solution for counteracting the effects of dry harsh winter air by adding essential moisture to any room. Soothe dry skin with added moisture so hands and lips are no longer dry.

Helps temporarily Relieve Congestion and Cough

  • Maintaining an indoor humidity level between 40-60% can reduce the survival of flu viruses on surfaces and in the air.*
  • *Studies have shown that keeping indoor air at an RH level of 40-60% reduces survival of flu viruses on surfaces and in the air compared to lower RH levels.

Helps You Breathe Better and Sleep More Comfortably

  • Comfortable humidity helps purify the air and keep throat and nasal passages hydrated. This can help you breathe better and sleep more comfortably.

Helps Protect Wooden Furniture, Floors and Musical Instruments

  • Low humidity causes wood to lose moisture and shrink. Extreme changes can causes warping and cracking.

Helps Keep Indoor Plants Healthy

  • Symptoms of dry air include curled leaves and dry leaf tips. Flower buds may even turn brown and fall off. Using a humidifier can help return moisture to the air promoting improved plant growth.

Helps Reduce Static Electricity

  • Static electricity is even more active when the air is dry, especially in the cold months when people turn on their heat. Returning moisture to dry air assists in reducing static shocks and static cling.
I hear the fan turning, but I don't see any mist. Is my humidifier operating properly?
Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no "mist" emitted. When operating normally you will feel only cool air coming from the unit. Monitor the water level in your Tank/Base. If you notice a decrease in the Water Tank over 24 hours then the unit is operating normally.
My unit has been running for several hours. I hear the fan spinning, but I do not notice the water level in the tank decreasing.
First, check the filter to ensure it is wet. If the pad appears dry, remove it from the Base and gently rinse under cool water. Reposition wet filter in the Base. You may also want to note the current moisture level in your home. If the humidity level is over 60% the unit will not put out much moisture as your air is already saturated. Also verify the upper enclosure and water tank are properly seated.
My filter has turned light brown and rust colored. Do I need a new filter?
Probably not. Since your filter has been made with Protec antimicrobial, the change in color indicates only a mineral deposit. Soak filter in a sink full of cool water to help break up deposits. The discoloration may remain but will not affect the humidifier's performance.

highly recommend

This is a great humidifier. It replaced one that was quite old and it runs so quiet which is wonderful and uses a lot less water to produce the amount of humidity needed. It's also much more energy efficient.

We have been using it in the baby room for over a month now. We like it very much. It's pretty quiet on the lowest setting yet still provides the fan white noise which helps baby sleep. So we have put away the white noise machine. We especially like the simple and effective design. Though it takes quite some space on the nightstand, for now we don't mind it. We hope it lasts.

Cool Mist Humidifier

Many years ago I owned their larger twin tank model model and when I needed a new one did not hesitate to purchase another Honeywell product. Thus far, this unit is working flawlessly, very quiet, easy to refill and well made! Looking forward to many years of service.

Quite good

I wanted a humidifier that could go through the dishwasher and this was one of the few that fit the bill. It has a large tank, and I appreciate having a filter system for sanitation.
