Which wick, filter or water panel does your humidifier take?

Type your model number and get the exact part, every equivalent, the replacement interval, and the lowest verified price — in one place.

Why this site exists

Humidifier wicks and furnace water panels are a fitment problem: the same wick hides under five part numbers across five brands, and the wrong one is a wasted $20. This site keeps one complete, sourced record per part — exact fit list, OEM and aftermarket equivalents, dimensions, replacement interval, and hand-checked prices with the store and date printed next to every number. The whole dataset is open: parts.json · how agents should use it.

Amazon is the buy button on part pages because it is this site's affiliate route — but the lowest verified price is always shown as the headline, even when it is a store that pays us nothing. Amazon prices themselves are never quoted: Amazon blocks automated price reads.
