Is 70 Percent Humidity High

Controlling your home’s humidity level can greatly influence the overall comfort you experience and it can also help you reduce maintenance and save on your energy expenses.

70 percent humidity is considered high and your home is going to be most comfortable when you maintain the humidity levels at around 30 to 50 percent. 

You need humidity for your health and comfort but too little or too much can produce a lot of difficulties and struggles on the part of homeowners.

Humidity: What Is It, Anyway?

The relative humidity is the term used most of the time when defining the amount of water vapor present in the air.

Relative humidity refers to the percentage of the water vapor in air at a particular temperature as compared to the water vapor amount that the air can capably hold at that specific temperature.

Warm air tends to hold higher amounts of water vapor compared to cold air.

Once air at a particular temperature contains the highest water vapor amount it can carry at that temperature, the relative humidity is 100%.

If it just contains half the amount it can hold at that temperature, its relative humidity is 50%.

Concerns and Issues of High Humidity

Once the temperatures outdoors get warmer, you will experience higher humidity inside your home.

Excessive humidity can lead to condensation on your windows, moldy bathrooms, wet stains on ceilings and walls, musty odor, or a clammy feel to the indoor air.

Structural damage and rot can also happen as a result of long periods of high humidity inside your house.

There are also places where this can draw in pests. Bugs always search for water, and any amount of condensation can provide bugs with their required water.

High humidity can also prove to be very dangerous once it combines with high temperatures.

Drier air can provide comfort at increased temperatures so homeowners can turn up the setting of their central air conditioning systems, therefore lowering their energy use.

Higher humidity can also trigger some allergic reactions, lead to dust mite concerns, and contribute to constant allergies.

Mold can also produce easier when there is high humidity and they can pretty much appear anywhere and damage everything they grow on.

Mold spores can also pose a serious threat to asthma and allergy sufferers.

Dust mites also thrive in high humidity.

Concerns and Issues of Low Humidity

Once outdoor temperature falls, your furnace is going to work harder and run more.

During conditions of extreme cold, the humidity level of your home can drop to as much as 10%. By comparison, the relative humidity in the Sahara Desert is 25%.

If you consider how people feel most comfortable if the relative humidity is around 40%, you will understand how dry air indoors can take its toll on you and your family.

Low levels of humidity can cause static electricity, scratchy noses and throats, dry lips, hair, and skin, and chapping and itching.

Mucous membranes in the throat and nose dry out, which can worsen your discomfort and make you more prone to respiratory illness and coldness.

When the levels of humidity are low, the moisture in your body evaporates really fast that you will feel chilled even when you set your thermostat higher.

Your home is going to suffer as well. Low humidity can wreak havoc on furniture and woodwork.

You will notice hard floor warping and separation, shrinkage, wallpaper peels at their edges, the piano suddenly went out of tune, molding gaps appear, and drawers loosen.
