When it comes to indoor comfort and health, most people focus on temperature or air purification—but humidity is just as crucial. Keeping your indoor humidity in the ideal range helps protect your respiratory health, skin, sleep quality, flooring, and even your furniture.

Why Humidity Matters Indoors
Humidity is the amount of moisture in the air. The ideal indoor humidity level is between 30% and 50%. Levels outside this range—whether too low or too high—can have a noticeable impact on your comfort, health, and surroundings.
What happens if Your Humidity is Too Low?
1. Respiratory Discomfort
Dry air can irritate the throat, nose, and lungs, making symptoms of asthma, allergies, and sinus problems worse.
2. Dry Skin and Irritated Eyes
Low humidity pulls moisture from your skin, leading to flaking, cracking, and itchiness. Eyes may feel dry and irritated, especially if you wear contacts.
3. Poor Sleep Quality
Dry air can contribute to nasal congestion, snoring, or a scratchy throat—disrupting your ability to get restful sleep.
What if it’s too High?
1. Mold, Mildew, and Dust Mites
Humidity above 50% creates an ideal environment for mold spores and dust mites, which can trigger allergic responses and worsen respiratory issues.
2. Breathing Discomfort
Humid air feels heavier and may make breathing more difficult, particularly for people with sleep apnea, COPD, or asthma.
3. Interrupted Sleep
Sleeping in a humid room can leave you feeling sticky, restless, and overheated, lowering sleep quality.

How to Maintain Healthy Indoor Humidity
The oceans are more than just vast bodies of water — they are essential to life on Earth. Scientists estimate that nearly half of the oxygen we breathe is produced by the ocean*, much of it from plankton — tiny, floating plants, algae, and bacteria that photosynthesize. One tiny organism, Prochlorococcus, produces up to 20% of the oxygen in our entire biosphere, which is more than all the tropical rainforests on land combined!
As an air care brand, Blueair knows that clean air is vital to health and well-being, and our oceans play a significant role in providing the oxygen that we need. That’s why we’re proud to join forces with 4ocean to protect these vital ecosystems from the devastating impact of plastic pollution. Keeping the oceans clean helps to ensure that they can continue to support life both underwater and on land.
