Understanding Humidity Levels

Humidity refers to the amount of moisture in the air, playing a vital role in ensuring a comfortable and healthy indoor environment.

The EPA recommends indoor relative humidity (RH) should be kept below 60 percent -- ideally between 30 percent and 50 percent. 1

High humidity can promote mold, mildew, and dust mites, triggering allergies and respiratory problems. Conversely, low humidity can lead to dry skin and irritated eyes. Both high and low humidity can also cause structural damage to your home.

Difference Between A Dehumidifier And Humidifier

Humidifiers add moisture to the air by releasing water vapor into the air, increasing humidity levels and combating dry air caused by heating systems or dry climates.

Dehumidifiers extract excess moisture from the air by drawing in humid air, cooling the air to condense and remove moisture, reheating the air, and then releasing the dry air back into the room. This reduces humidity levels

Advantages Of A Humidifier Vs Dehumidifier

Humidifiers helps with dryness-related issues, such as dry skin, irritated nasal passages, and possibly sore throats or sinus problems by moisturizing the air. Humidifiers can also help reduce static electricity. Low humidity can cause wooden furniture and floors to dry out and crack, and boosting humidity levels with a humidifier can help prevent such damage.

A dehumidifier helps with high moisture-related issues, such as mold spore and mildew growth and musty odors. Dehumidifiers help reduce these allergens to improve indoor air quality. Excessive humidity can also cause structural issues like warped wood and peeling paint. Dehumidifiers control humidity levels, helping safeguard your property.

Choosing A Humidifier Vs Dehumidifier For Your Home

Deciding between a humidifier and dehumidifier involves evaluating your specific needs and living conditions.

If you live in a dry climate, a humidifier can add moisture to the air, improving comfort. In humid regions, a dehumidifier can remove excess moisture, preventing mold growth.

The humidity level of your home helps determine which humidification option is right for you. When humidity levels are very low - oftentimes during winter when indoor air is typically more dry - a humidifier may be best. When humidity levels are overly high - oftentimes during summer when indoor air is typically more moist – a dehumidifier may best suit your needs.
