Summer weather can affect the quality of both indoor and outdoor air. Indoor air carries allergens, bacteria and mold, and dry air can harm your health. Cleaning your indoor air can prevent you and your family from getting sick this summer.

Adding a cool mist humidifier can clean your indoor air, relieving allergies, protecting your children and moisturizing your skin. Cool mist humidifiers release moisture into indoor air. Unlike warm mist humidifiers, they don’t add heat to your home, making them great for summertime use.


There is an increase in allergens such as pollen, pet dander and mold in the summer. If you are prone to allergies, you can develop symptoms such as coughing, sneezing and congestion. A cool mist humidifier releases moisture to reduce indoor allergens, helping manage your symptoms.


Summer weather may cause dry skin. Indoor air during the summer months can pull moisture from your skin. Cool mist humidifiers combat dry skin by adding moisture to indoor air.


Cool mist humidifiers are a safe option for children. When you use warm mist, you risk your children getting burns or scalds. Using cool mist humidifiers keeps your children safe while you enjoy filtered indoor air.


  • Compact size: Some cool mist humidifiers are oval-shaped or are a smaller size so they can fit on a nightstand, desk or end table.
  • Automatic shutoff: Once the water runs out, some humidifiers automatically shut off to prevent damage to their mechanical features.
  • Essential oil diffusion: Some cool mist humidifiers are also essential oil diffusers, letting you enjoy both aromatherapy and clean air.
  • Rotating nozzle: A 360-degree rotating nozzle ensures that the cool mist is evenly spread across your room.
  • Large water tank: Most cool mist humidifiers hold two or more liters of water that last nine hours or more.
  • Quiet technology: Cool mist humidifiers have a whisper-quiet operation that doesn’t create an unpleasant noise in your home.
