Honeywell Filter Free Warm Moisture Humidifier Review

Dry air is a problem during winter. Humidity can drop to around 20% which makes breathing very difficult for people with sinus and allergy problems. If you have a cold, low humidity only makes things worse. A good humidifier can help increase the moisture in the air and make respiratory issues more bearable. If you need a misting device for a single room or studio, you might want to try the Honeywell filter-free warm moisture humidifier.

Honeywell has built a reputation for good quality appliances, and its latest warm mist humidifier adds another feather to its cap. The form factor of the HWM705B is perfect for a medium-sized room and its sleek, modern design complements any interior.

This humidifier produces a soothing warm mist that adds moisture to the harsh winter air, preventing cracked lips and stuffy nose. It has two output settings, a one-gallon water tank, auto shutoff function, and a built-in medicine cup.

Sleek and attractive design

The tabletop size of the filter-free warm moisture humidifier from Honeywell makes it easy to transport if you need to move it from your bedroom to your work area. Its unique shape and color stand out among the ubiquitous round white misting devices on the market.

A fine addition to any room, the Honeywell filter-free humidifier has a space-saving kettle-like contour with a clear frosted tank and a solid black finish.

Easy to use

The warm moisture humidifier has a manual selector knob with three power settings: off, low and high. This allows you to choose between two speeds to adjust moisture output and noise level. At its lowest setting, this humidifier can last for up to 24 hours straight.

While most humidifiers continue to consume electricity even when the tank is empty, this model activates its auto shutoff function when water runs out. This saves you money on your electricity bill and, more importantly, protects your device from burning out. The last thing you want is an overheating humidifier that sparks and starts a fire. Working in tandem with the auto shutoff function is a refill light that illuminates to remind you to fill the tank again.

The air that you breathe can get pretty dry when humidity in your room drops to around 20%. When you turn on the Honeywell warm moisture humidifier, it goes to work immediately. Switch the knob to the highest setting and within an hour the room will reach a very comfortable 40% humidity. Try to keep room humidity within 30% and 50% for a good sound sleep.

Integrated medicine cup

The Honeywell filter-free warm moisture humidifier produces a warm visible mist that makes breathing more comfortable during dry winters. However, if you are sick, sometimes you need more than just water vapor to soothe that clogged nose and sore throat.

On top of this model is a built-in cup for adding liquid medicine which you can inhale while the humidifier is turned on. Mix in a few drops of camphor, eucalyptus, cedar leaf or nutmeg essential oil to reduce congestion especially when sleeping.

You can also use your Honeywell warm moisture humidifier for aromatherapy. If you are suffering from insomnia or any other sleep disorder, infusing the warm vapor with lavender essential oil can help you relax when going to bed. Rose, sandalwood, and peppermint essential oils are great for adding a refreshing and irresistible scent to your room.

Easy to maintain

One of the most tedious tasks of maintaining a humidifier is the use of a filter. Dust and dirt can accumulate in the filter so you have to be mindful to clean or replace it regularly. The Honeywell humidifier eliminates that hassle with a completely filter-free operation.

The tank of this humidifier is also removable, making it easy to wash and dry. With the tank detached from the body, it will be also easy to clean the other components of the device.


Honeywell Filter Free Warm Moisture Humidifier is specifically designed to add moisture to a medium-sized room. If you need to humidify a large area, this will not work for you.

The internal fan effectively increases moisture in the air that you breathe, with the one-gallon tank capable of working throughout the night. The built-in medicine cup could be a big help to family members who have respiratory issues.

This Honeywell humidifier is very easy to use. Just fill the tank with water, connect the device to a wall outlet, and turn the knob to one of two output settings. It has removable parts that are easy to clean and you do not need to buy any filters at all.

Unlike most humidifiers that inhibit sleep, this Honeywell warm mist humidifier has a dim indicator light and operates quietly in the background.

If you plan on purchasing a humidifier, you need to choose a model that is easy to use, energy-efficient, low maintenance, and affordable. The Honeywell Filter Free Warm Moisture Humidifier certainly meets all of those requirements.
