Product Specs

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.

Its important to have a humidity monitor so you can see if your humidifier is a good fit for the room and what setting it should be on. Haven't had a chance to compare to other hygrometers but it seems accurate.

We live in a changeable climate. Indoor air in cold winter months can be very dry, but much of the rest of the year can be humid. I need to monitor indoor air carefully, and this item is unobtrusive and can be moved from room to room as needed.

We bought 2 Honeywell Humidity Monitors, in order to manage the humidity levels in our home. I don't know if they are 100% accurate, but they do help to give us an idea of what the humidity level is in the living room and bedroom. We bought a 2nd Honeywell Humidifier, since our apartment is so large. I think once we start using the bigger humidifier in the living room and the smaller one in the bedroom, we will be able to get a more accurate reading. Just one suggestion. It would be nice if the monitors were lite up, so we could see the numbers in the dark.

This seems to be pretty accurate from what I can tell. I got it for the humidity reading more than the temperature. My HVAC has a humidity sensor which is in another room and this device is in my bedroom where I run the humidifier. From what I can tell this is giving me a pretty accurate reading.

The display on this product is easy to read and it is a good way of knowing when you should use your humidifier. I found out that the humidity in my room was too low, which makes sense for the symptoms I was feeling. I would recommend this product.
