how to set humidifier in winter

Cold, dry air is a common complaint for people who live in Canada and constantly have to deal with harsh outdoor temperatures, and it may have a major effect on your comfort and health. If you want to keep your home air healthy during these months, you must use a humidifier and set it to the ideal settings to ensure the optimal humidity levels in your home.

In this article, we’ll go over why it’s so important to keep your home at a consistent humidity level as per the seasons and how to adjust your humidifier for better air quality in the winter.

Why should you maintain your home's humidity level?

Keeping the relative humidity in your home at an appropriate level throughout the harsh Canadian winters has many advantages:-

Maintaining an appropriate relative humidity in your indoor air helps keep your nasal and mucosal membranes from drying up, which in turn lessens your vulnerability to infections and makes the flu and common cold more bearable. In addition to making winter more tolerable, the right humidity can reduce the occurrence of bothersome dry coughs and sore throats.

Skin irritation, itching, and flaking can result from the loss of moisture caused by dry indoor air. Lotions and balms aren’t necessary as much when the humidity is just right because your skin keeps its moisture. You can save money and energy by turning down the thermostat when the air is humid since it feels warmer than dry air.

Paint chips, wood shrinks and cracks, and electronics are vulnerable to static electrical charges in dry environments. Preventing these problems and maintaining the structural integrity and attractiveness of your home’s interior is possible by keeping the indoor humidity at a prescribed level.

How can you maintain the humidity level of your home?

To keep your home comfortable, and healthy, and your possessions lasting during the harsh Canadian winters, it is essential to maintain the appropriate humidity levels inside. A comprehensive method for keeping an eye on and regulating the relative humidity is as follows:

You can't have a relative humidity (RH) monitor without this tool. With the help of a hygrometer, you can get precise readings and regulate your humidifier appropriately. Particularly sensitive sections, such as bedrooms or a study with wood furniture, should have a hygrometer in addition to the main living areas.

Keep an eye out for telltale signals of high or low humidity levels around the house. Signs of mold growth, such as condensation on windows, wet patches on walls or ceilings, and a musty odor, can be caused by excessive humidity. Conversely, elevated static electricity, dry, itchy skin, or worsened respiratory problems are indicators of excessively low humidity levels. When exposed to extremely dry circumstances, wooden furniture or flooring may also exhibit shrinkage or cracking.

Indoor air quality is susceptible to winter weather fluctuations. When the temperature drops significantly, it's extremely important to adjust the humidifier settings to the current weather. To avoid condensation on windows and possible mold problems, it is recommended to keep indoor humidity lower when the outside temperature is colder.

To keep the humidity at a constant level according to the readings from your hygrometer, utilize the automatic setting on your humidifier or link it to your smart home system. By eliminating the need for human intervention, this automation can make it easier to keep indoor temperatures stable and comfortable.

Ideal Humidity Settings for Canadian Winters

To stay comfortable, healthy, and home-protected during the Canadian winter, it is essential to maintain an appropriate humidity level, be it on your regular humidifier or your furnace humidifier. The amount of moisture that the air within your home may safely retain without leading to problems like mold or condensation is heavily influenced by the current external temperatures, which in turn determine the optimal levels of interior humidity.

Guidelines for Setting Humidity Based on Outdoor Air Temperature

Below -10°C (14°F): Indoor humidity levels of about 20% are recommended in temperatures below -10°C (14°F). By keeping it on a low setting, you can keep condensation from forming on surfaces inside your home, such as windows due to the cold air outside.

-10°C to 0°C (14°F to 32°F): If the outdoor temperature ranges from -10°C to 0°C, you may balance the demand for moisture with the risk of condensation by setting your humidistat to 25% when temperatures slowly rise. At this level, the air will be somewhat moistened without being weighed down.

0°C to 10°C (32°F to 50°F): At temperatures between 0 and 10 degrees Celsius, a relative humidity level of 30% is usually quite acceptable and even desirable when it comes to air conditioning. Without increasing humidity to the point that it could condense on surfaces like water vapor, it helps alleviate the dryness brought on by your heating system.

Above 10°C (50°F): You can set the humidity to 35–40% when the outside temperature is cool but not freezing, which is above 10°C (50°F). Typically, this range is perfect for making people feel more at ease and making sure there’s enough humidity and warm air to avoid issues such as dry skin, mucous membrane dryness, and static electricity.


Making sure your home stays a haven from the harsh Canadian winter requires proper humidifier settings. Your comfort, your health, and the longevity of your home’s contents can all be enhanced by carefully controlling the relative humidity levels. Since every house has its own distinct atmosphere, these rules should only be used as a guide; make any required adjustments to discover what suits your home the best.
