How to Naturally Reduce Humidity in Your Home

How to Naturally Reduce Humidity in Your HomeIn our region, high humidity in the home can be a problem. In summer when the air is warm, it will hold more moisture and make us feel warmer than we need to. That means turning the air conditioner down just to feel comfortable. Any time of the year, high humidity can encourage the growth of mold, mildew and fungus, which can destroy paper, drywall, paint and other materials — plus, it’s unhealthful to breathe these pollutants.

The best way to control humidity is to install a whole-house dehumidifier. Under most circumstances, your A/C performs that function adequately, but if you have an excessively moist home, it can be overwhelmed.

Learn how to reduce humid conditions with the following tips and maybe you’ll see results that will help you until you can plan for a dehumidifier.

Tips for Reducing Too-Humid Conditions

  1. Sequester plants. Having lots of plants in the home is a lovely way to decorate and to improve air quality, but plants also raise moisture levels. Round them up and move them to one room.
  2. Keep your air filter clean. A dirty air filter won’t do as good a job allowing proper air flow into your HVAC system. Slower air flow can mean the system won’t dehumidify the air as effectively. Change the air filter frequently.
  3. Take shorter showers. If you live with several people, long and frequent showering can up moisture in the air significantly. Ask people to take shorter showers. Crack the window and run a fan so the humidity can escape.
  4. Install kitchen or bathroom ventilation. Ventilation exhaust fans are not expensive to purchase or install, and they do a a great job of removing moisture from bathrooms and around the kitchen range.
  5. Fix leaks asap. As soon as you realize a faucet, a pipe, the attic or ceiling is leaking water, fix the leak so you prevent flooding and lower moisture levels. Also be vigilant about the HVAC’s condensate drain; a plugged drain can also boost air moisture.

Solve Problems With a Humidifier Throughout Heating Season

Solve Problems With a Humidifier Throughout Heating SeasonWinter in the Portland area has its own set of challenges. One problem that doesn’t have to be too difficult to deal with is dry air from your heating system.

A good level of humidity inside a home ranges from 30 to 50 percent. When you use your heating system, it naturally removes humidity, lowering it as far as 10 percent.

How to Tell if Your Home’s Humidity is Too Low

Obvious symptoms of too-dry air include:

  • Dry, cracking skin on your hands and feet
  • Chapped lips
  • Sore, dry nose
  • Bloody nose
  • Itchy skin that is soothed by lotion

Additional Low Humidity Problems

In addition to these minor discomforts, having low humidity can create the perfect atmosphere for certain types of viruses. It can also worsen the symptoms of people who suffer from allergies and eczema.

Your house can feel some discomfort from low humidity, too. When the air is too dry, you can start to see peeling and cracks in your paint and wallpaper. All the wood in your house needs a certain level of humidity to stay in good condition.

The Solution: A Humidifier

If you’re seeing signs of dry air in your home, there’s a simple solution. You can get a humidifier to help add moisture to your air.

There are two choices in humidifiers. Individual units cost less but don’t allow you to have much control over the amount of humidity in your air. You also have to be careful to keep them clean. The damp environment inside the unit can be a good growing place for mold and mildew if not properly maintained.

A whole-home humidifier is a bigger investment, but it allows you to set your humidity where you want it. This can be particularly useful when you have family members with breathing problems. Whole-home humidifiers release their water vapor into your ducts, allowing the humidity to reach all parts of the house evenly.

Maintain Proper Humidity in Your Portland Home for Year-Round Comfort

Maintain Proper Humidity in Your Portland Home for Year-Round ComfortCorrect home humidity levels are not simply a matter of comfort. Real health issues for your family, your home’s value, and HVAC equipment condition are all affected by home humidity.

Understanding Humidity

The amount of moisture—water vapor—in the air is humidity, but that may be less important for your family’s health than relative humidity. Relative humidity is a measure of the actual humidity versus the theoretical maximum water weight the air could contain. Strive to keep your home’s relative humidity in a comfortable range, generally 35 percent to 45 percent.

Health Concerns

If your home is too dry, family members may suffer nosebleeds, sinus trouble, headaches and itchy eyes. Too moist a home and you face unpleasant risks:

  • Increased insect activity, including dust mites, psocids (booklice), silverfish and grain beetles
  • Mold and mildew
  • Peeling wallpaper
  • Doors that cannot close
  • Condensation
  • Increased allergic reactions, difficulty breathing, and sickness

Equipment issues

Home appliances, HVAC components and any electrical devices can be harmed by high home humidity. The freezer in your refrigerator may not fully defrost and electrical contacts can corrode. Low home humidity increases static electricity, which can fry the circuitry of laptops.


Humidifiers add water vapor to the air, using either portable models or whole house units that are integrated into your house HVAC system. Whole-house humidifiers have several advantages:

  • Your home is humidified whenever the HVAC system is on.
  • Every room of your home is humidified.
  • The humidified air has been cleaned by the HVAC filters.


Too much home humidity is solved with a dehumidifier. Again, you can choose small portable models, or opt for professional installation of a whole-house dehumidifier by your HVAC contractor.

Help your mechanical dehumidifier with a few steps:

  • Always run exhaust fans in bathrooms and kitchen.
  • Limit shower lengths to five minutes.
  • Keep only a reasonably small number of houseplants.
  • Open windows when you know you will be generating humidity (boiling water, steam-ironing, or showering).
  • Run the dishwasher only when full and when the central air conditioner is not on (generally overnight).
