We've upgraded our filter to be better than ever! The new filter uses the same wicking paper as the original but now has an added pre-filter layer to trap dust and larger particles from the air to stop dust before it reaches your fan.[2]

• For use with all versions of Bedside or Nursery Humidifier (not Large Room Humidifier)
• Made from wood pulp
• Filters air and water before evaporation for cleaner hydration.
• MERV 5 pre-filter and antimicrobial[4] core captures dust, particles, and waterborne contaminants to inhibit mold growth inside the device.[1]
• Replace every 45 days
