Verified replacement keys

Find the filter key before you buy the filter.

Purifier Part Check separates replaceable sets from washable or permanent parts. This beta gives a result only when the manufacturer and exact model are verified.

Current coverage: Levoit Core 300-P and Winix 5500-2. A missing model returns “unsupported” instead of a guessed shopping link.

Model lookup

Choose the label exactly

Manufacturer

Exact model

No result until both fields are selected.

We use a closed allowlist—never a fuzzy model match.

Why this exists

Similar model names can point to different filter packages.

Exact model first

We do not turn “Core 300” or “Winix 5500” into a purchase answer. The suffix is part of the lookup key.

Package roles stay separate

A washable pre-filter, carbon layer, and replaceable HEPA set are not treated as interchangeable parts.

Official sources stay visible

Every supported result names the source, check date, included parts, and the conditions we could not verify.

No link is safer than a bad link

Unsupported models receive a clear stop state and a route back to the manufacturer—not a generic retailer search.
