What Humidity Percentage Should It Be Inside Your Home?

Humidity Percentage

According to you and your family, your home's appropriate humidity percentage level will vary. It will largely rely on the season and the location in your home where your family likes to gather together.

What Should the Proper Humidity Percentage Level Be in Your Home?

It is recommended that your home should have a relative humidity of 40% to 60%. However, levels should be kept below 50% in order to prevent the growth and spread of mold. This can be changed to suit your comfort levels. Your home's relative humidity should correspond to the absolute humidity outside.

Absolute humidity levels fluctuate with temperature and season. More moisture is present in the air during the summer, while substantially less is present during the winter.

Below is a scale to help you better understand the humidity percentage in your home depending on the outside air:

  • Indoor humidity levels shouldn't rise above 50% while the outside temperature is higher than 50 °F.

  • Indoor humidity levels shouldn't get above 40% while the outside temperature is above 20 F.

  • Indoor humidity shouldn't be higher than 35% and the outside temperature should be between 10 and 20 °F.

  • Indoor humidity levels shouldn't be greater than 30% for an outdoor temperature of between 0 and 10 °F.

  • If the outside temperature is between -10 and 0 degrees, the inside humidity shouldn't be higher than 25%.

  • If the outside temperature is between -20 and -10 degrees Fahrenheit, the inside humidity shouldn't be higher than 20%.

  • When the outside temperature is -20 F or lower, the inside humidity shouldn't get above 15%.

Issues Associated with High or Low Humidity in Your Home

There are various signs that your home is excessively dry because of low humidity. You could notice:

  • Dry or itchy skin.

  • You get sick often.

  • Damage to hardwood floors and furniture. This can include paint chipping from wooden furniture and floors as well as cracking or splitting in the wood.

If your home's humidity is too high, you'll experience the following effects:

  • High relative humidity encourages mold growth and spread.

  • Those with asthma and allergies may see their symptoms go worse.

  • Difficulty sleeping.

  • Windows have condensation on them.

How to Get the Right Humidity

In the winter, installing a humidifier if you don't already have one will be quite helpful. Keep in mind that the air will be naturally humid in the summer, so you may put the humidifier away for the dry winter months.

For the comfort of your family, maintaining the ideal humidity level in your home will be extremely beneficial. As a result, maintaining the correct level of humidity in your home is essential for both the structure and health of your home.
