Keep Humidity out of Your Home In the Winter
When the winter months arrive, you might notice seasonal changes in your home such as condensation forming on the windows. Unlike other areas of the country, the Pacific Northwest tends to become more humid during the winter due to our famously wet weather. By knowing how humid your home is and how to control it, you’ll keep your home and family healthy and keep the air inside healthy.
Ideal Winter Indoor Humidity Levels
The ideal relative indoor humidity level for a home in the winter is between 30 and 40 percent. As a result, heating Portland homes becomes an important task to keep homeowners healthy. Humidity levels below 30 percent will make your home feel uncomfortable and can cause wood items to dry. Relative humidity levels of higher than 50 percent promote mold growth, dust mite infestations, rot, corrosion, and water stains.
Signs of High Humidity Levels in a Home
- Condensation forms on windows when temperatures drop
- The home feels muggy, clammy or sticky
- The home has a musty odor
- You or a family member experience allergy symptoms while inside the home
- Mold begins to grow on windows, around pipes, in the corners of walls, on the ceiling, or in the bathroom
- Water stains on walls or ceilings
How to Reduce Humidity Levels in Your Home during the Winter
The first step in reducing winter humidity levels in your home is to identify the source of the moisture. Knowing why your home is overly humid will allow you to have a targeted approach to resolving the issue. Excess moisture may result from:
- Poor or improper ventilation
- Not using exhaust fans in the kitchen or bathroom
- A leaky roof
- A damp basement
- Too many water-loving houseplants
- An HVAC system that is not the correct size or needs repairs
- The clothes dryer failing to vent outside the home
- Storing freshly cut wood inside the home
Once you’ve identified where excess moisture is coming from it’s time to look for ways to reduce moisture build up. While there are a number of natural ways to reduce humidity levels, there are also a number of steps you can take around your home to decrease moisture build up.
Heating Portland homes in the winter helps keep excess moisture at bay. Because warm air holds moisture, your home should not be overly humid to begin with or you’ll turn it into a sauna, which will only compound the problem. Use dry heat and ensure adequate airflow when warming your home.
Use a dehumidifier
Dehumidifiers dry water out of the air, speeding up the natural evaporation process. The units come in a variety of sizes. They’re available as portable units that you can move from room to room and as fixed appliances that are part of an HVAC system. Dehumidifiers are particularly useful in basements, laundry rooms, bathrooms and other areas that have high humidity levels.A good type of dehumidifier to use is one with a built-in humidistat. A humidistat is similar to a thermostat, but it measures relative humidity levels in the area and signals a humidifier to turn on or off accordingly. Use a hygrometer to learn if a space is too humid or dry before purchasing equipment.
Keep your gutters and downspouts clear. Verify that the downspouts and landscaping direct water away from your home.
Insulate your pipes
Upgrade your windows
High-efficiency windows, such as double pane windows or those with an insulating film reduce energy exchanges during the winter, so they’re less likely to fog-up. Similarly, ensure the weather stripping and caulking around windows is in good shape.
