Excess humidity or dry air can have adverse effects on your household items. In this section, we will explore how high and low humidity levels impact your furniture and appliances and what you can do to prevent damage.

Effects of High Humidity on Furniture

When humidity levels are high, your furniture may absorb some of the excess moisture, causing it to warp, swell, or crack over time. Wood, in particular, is prone to damage from high humidity because it naturally expands and contracts when exposed to moisture. As a result, high humidity can cause valuable wooden furniture pieces to lose their shape, warp, and age prematurely.

Moreover, high humidity levels can lead to the growth of mold and mildew on upholstery, carpets, and curtains, causing unsightly stains and unpleasant odors. Mold and mildew can also trigger allergies and respiratory issues, making it a potential health hazard.

Effects of Low Humidity on Household Appliances

Low humidity levels can also be harmful to household appliances, especially those that depend on moisture to function correctly. For example, dry air can cause wooden piano keys, guitar frets, and other musical instruments to dry out and crack. It can also lead to static electricity buildup on electronics, resulting in device malfunctions and reduced lifespan.

Moreover, low humidity can cause air conditioning systems and refrigerators to overwork, resulting in higher energy bills and reduced efficiency. Dry air can also cause cracking and peeling of painted surfaces, especially on walls and ceilings.

Preventative Measures

To prevent damage from high and low humidity levels, it’s essential to monitor and control the air moisture levels in your home periodically. Here are some tips to help maintain optimal humidity levels:

  • Install a dehumidifier to reduce excess humidity levels.
  • Use air conditioners and fans during warm, humid weather to circulate dry air.
  • Seal all windows and doors to prevent moisture from entering.
  • Use a humidifier during cold, dry weather to add moisture to the air.
  • Store wooden furniture and musical instruments in a cool, dry place to prevent warping and cracking.

By taking these preventive measures, you can help preserve your household items and ensure their longevity. Regular maintenance and monitoring of air moisture levels can help protect your investments and maintain a comfortable and healthy living environment.

7. How to Measure Humidity Levels in Your Home Accurately?

One of the most critical steps in managing indoor humidity levels is accurately measuring it. Knowing the humidity levels is essential to determine whether the air in your home is too dry or too damp. Fortunately, you don’t need to hire a professional to measure the indoor humidity levels. Here are some ways to accurately measure humidity levels in your home.

Hygrometers: Hygrometers are devices that measure humidity levels. They have two types- analog and digital. Analog hygrometers look like old temperature gauges with a needle that points to the humidity level, while digital hygrometers have a digital display. Using a hygrometer is relatively simple- just place it in the room you want to measure, and then read the humidity level.

Thermometers: While thermometers are not specialized devices for measuring humidity, they can still provide accurate readings of it. Many modern digital thermometers have a humidity sensor build in them, which can show both the temperature and humidity levels. However, only trust the readings of thermometers that are designed to measure humidity levels as using a standard thermometer’s humidity measurement may not be as accurate as a specialized hygrometer.

Non-electric Method: You can also use a more traditional and non-electric method to measure humidity. It involves the use of a bundle of hair from a horse or cow and a ruler. The hair bundle is usually about ten inches long and 2-3 inches wide and is tied with a string to the ruler. The bundle is placed in a room for about an hour, after which the hair is measured with the ruler to determine the humidity level. Such non-electric methods may not be as accurate as their digital counterparts, but they can be useful in a pinch.

No matter which method you choose, the most important thing is that you have an accurate reading of the indoor humidity levels in your home. It will help you take necessary actions and make sure that your home’s humidity levels stay within a healthy and comfortable range.
