We've upgraded our humidifier filter to be better than ever! The new blue-wrapped humidifier 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.*

·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* core captures dust, particles, and waterborne contaminants to inhibit mold growth inside the device.*

·Replace every 6 weeks

*Humidifier does not treat air; inhibits mold growth in device & filter. Third-party testing shown to inhibit growth of Aspergillus niger (commonly known as Black Mold) based on standard AATCC 30-2017

*Third-party lab tested to MERV5 efficiency

*The filter media has been treated with an antimicrobial agent to inhibit fungal growth within the product. This treatment does not protect users or others against bacteria, viruses, germs or other disease organisms.
