Before you buy this replacement

Confirm your exact device model, not only the product family.
Compare the old part number against 35 Water Panel.
Check whether the listing includes the full kit or only one filter piece.

Not a universal part

35 Water Panel should be matched to listed models and official part references. Similar-looking replacements can differ by seal, frame, cartridge latch, chip requirement, bag type, or pack contents.

Risk note: AprilAire water panel numbers are not size tiers. Match the humidifier model list before substituting panels.
