What Is Good Humidity & How To Measure It?

Humidity is the quantity of water steam in the air. The reason for the humidity is the water that evaporates and turns into tiny droplets that are suspended in the air. These droplets are tiny so they are characterized as gas rather than liquid. Relative humidity (RH) is the quantity of saturated air at its current temperature. When warm air can grab more water steam than cool air, the RH of the warm air will be lesser than the cool air will, even with the same quantity of water.

If the RH is high, the air is damp and sticky. When the RH achieves 100%, it starts to condense and fall as rain.

What Is A Good Humidity Level?

Generally, the recommended humidity level at home should be between 30% and 60% in each room of the resident. If the humidity level falls outside of this normal indoor humidity vary, you should find the dry air causes:

  • Damage to the wooden floor, and furniture, including cracking;
  • A boost in static;
  • Dry skin, eyes, and hair;
  • Dry throat and cough may lead to an inconvenient night's sleep;

If the RH level goes above 70%, it may lead to such issues:

  • Dehydration;
  • Fatigue;
  • Muscle cramps;
  • Damp and mold - generally an issue in the bathroom;
  • Respiratory condition flare-ups.

So, maintaining the proper humidity level is not only good for the building but also for the health of residents.

What Is A RH?

RH is the actual quantity of water steam present concerning the capacity the air has at a certain temperature. When it is a bit misleading, you should consider the capacity as the quantity of water steam that the air may grab, so it is generally incapable of physically grabbing onto the water steam as it moves too fast. While the specific water steam saturation point or capacity is maintained, the water steam in the air will condense as moisture, making the air feel damp. As water steam, RH may be expressed in terms of pressure or density. In both cases, it is expressed as the level percentage and calculated by dividing the actual vapor pressure by saturation vapor pressure or actual vapor density by saturation vapor density and then multiplying the quantity by 100.

Humidity VS RH

Humidity and RH are not the same. Applying the term humidity relating to the condition of the air is correct, but relating only to the quantity of water steam present in the air, which is also known as absolute humidity.

The quantity of water steam in the air is contingent upon the air temperature. The higher the air temperature, the more water steam it can grab, and the higher the potential humidity.

Water steam pressure is determined in millibar (mb, mbar), which is a measurement unit of pressure where 1.013 mbar is equal to the Earth's atmospheric pressure at sea level.

Water steam density is determined in grams per cubic meter of air at standard sea-level atmospheric pressure.

Note: Level aspects into atmospheric pressure - the higher the level is, the lesser the atmospheric pressure.

What Is A Comfortable Indoor Humidity Level?

Regulating the humidity level at your residence is more essential than most might consider. Having too low a humidity level leads to such issues as dry skin and a boosted susceptibility to bacteria and infections. Low humidity level also leads to damage to the wood floors and furniture. Nevertheless, the high humidity levels may cause mold to grow quickly and even damage wooden objects at home, cause discomfort and form a muggy living environment.

The proper humidity level differs according to the season with the severe climate changes in summer and winter. However, there is a general idea of what humidity level should be at your residence to maintain comfort.

The correct humidity level at the residence while the summer should be from 40-50%. If the humidity goes over 60%, it will lead the house to become moist and muggy.

The correct level of humidity while the winter should vary from 30% to 40%. If the humidity is less than 40 % it will avoid condensation from creating on the windows and forming excessive moisture.

Generally, the indoor humidity should be 45-55% year-round and slightly lesser during the winter months. If your residence is out of the required humidity, you may feel a dry or muggy living environment, which means you should get the proper equipment.

What To Use To Check The Humidity Level?

Analog Humidity Monitor is a simple, affordable tool to check the precise humidity level +- 1-3%. They may be effective if you simply want to check the humidity in the spring or fall, to consider whether to turn on or turn off the dehumidifier as the seasons change. You should set the humidity monitor in one place and wait for an hour to get precise readings.

A digital hygrometer is a costly device, but it provides greater precision, closer to +- 2% on the continuum from 5% to 25% at the dry end, to 95% at the wet end of the spectrum, and also temperature measurement from 32*F to 122*F (0*C-50*C). There are various sizes and shapes of digital hygrometers. They may be portable, handheld meters, or be the size of a pen and include a pocket clip and built-in sensor. Several models allow setting the specific alarm to warn the user about too low, or too high a humidity level.

What Is A Humidifier And How To Use It?

A humidifier is a device that allows adding moisture to the air at your residence. There are various types of humidifiers:

Warm Mist Humidifiers:

The steam humidifier steams boiling water and then releases it into the air. As water is boiled before being released into the air, the humidifier tends to be one of the most hygienic types among others.

The central humidifiers are devices that are connected to the residence's central air conditioning/heating system. There are various types of central humidifiers, but several of them are from steam that is distributed back into the house's airflow.

Cool Mist Humidifier

An ultrasonic humidifier operates by utilizing vibration to release water molecules into the air. This humidifier is silent and as they don't apply boiling water, they are a safe solution for children.

Evaporate humidifiers release moisture into the air through the fan. These humidifiers are affordable and theirfilter allows for avoiding bacteria from the air.

Impeller humidifiers utilize a spinning disk that releases water into the air through the diffuser. The spinning disk makes a low humming noise, and the tank needs to be cleaned regularly to protect bacteria from being released into the air.

Tips For Maximizing The Work Of The Humidifier

To achieve the most out of your humidifier there are some tips on using it properly:

  • Set the device at the ideal level from 30% to 50%;
  • Change the water in the humidifier daily to prevent it from bacteria and other infections;
  • Use only pure or distilled water to prevent minerals of tap water from releasing into the air.;
  • Clean the device with hydrogen peroxide or disinfectant recommended by the manufacturer every few days;
  • If the humidifier includes a filter, change the filter following the manufacturer's instructions.

What Is A Dehumidifier And How To Use It?

A dehumidifier is an electrical device that allows for reducing and maintaining the humidity level in the air. This device is useful to reduce musty odors and prevent the growth of mildew. The device operates by removing water molecules from the air. The dehumidifier is an ideal solution for those who have allergies or live in a humid climate.

The dehumidifier allows eliminating the potential appearance of mold on furniture, curtains, bed sheets, and clothing. The device also allows reducing dust, as it can cause allergies.

Tips For Maximizing The Work Of The Dehumidifier

Improve the operation of the dehumidifier according to the useful tips:

  • Clean the device according to the manufacturer's instructions. If it is required, you may get the demineralization products;
  • Set the humidity level from 30% to 50% to make sure your residence isn't too dry or too humid;
  • Use a cool-mist humidifier in a child's room to prevent accidental burns.
  • The moisture the dehumidifier grabs from the air ends up in a tank. Try to clean the tank regularly, relating to how often you apply the dehumidifier and how long it operates with each session.
  • When you use the dehumidifier, keep windows and doors closed.

What Is A Humidifier-Dehumidifier Combo?

So, what if you need to regulate humidity, whether it is high or low, at your residence by applying one single machine? All these operations are possible with the humidifier-dehumidifier combo. This device is a combination of two, with all features and technologies of both.

The humidifier-dehumidifier combo is an ideal device for regulating and reducing humidity at your residence. The device has three options: reducing humidity, a cool or warm mist, and a medium or high level of humidification. According to the humidity level, they may be too small or too big for several rooms. In addition to maintaining the humidity at the optimum level, the humidifier-dehumidifier combo also helps to remove excess moisture in the room. Several models include LED displays to show the current humidity level in the area.


Too dry or too humid air can affect your health. Adding a few quantities of moisture to the air may be an easy and ideal solution to the problem. Be sure not to utilize one excessively so that the humidity level is too high, which may cause mood and dust mite problems.
