Buying Guide: Replace a Part or the Unit
Keep these points in mind before you buy.
When a part is not enough
Cracked tanks, warped caps and damaged bases can leak or harbor grime; contact the maker for genuine parts, or replace the humidifier.
Match the model number
Every purifier uses its own filter shape. Find the model on the label and match the filter part number before ordering.
Replace wicks on schedule
Honeywell suggests replacing Filter A about every one to three months and Canopy about every six weeks; stiff, crusty wicks lose output.
