BenchPicked data

Air purifier specifications and ownership-cost dataset

Normalized CADR, room-size, noise, power, filtration, and evidence-status fields for the current BenchPicked air-purifier set.

Version 2026.09.24 11 records Updated 2026-09-24

What the data represents

Values are normalized from the named manufacturer and standards-directory sources already attached to each BenchPicked page. Units are preserved rather than converted when operating conditions are not equivalent.

This is a source-attributed comparison dataset, not a BenchPicked laboratory test. The Levoit Core 400S CADR row remains pending verification pending a same-model AHAM or equivalent primary record.

Room-size and ownership-cost calculator

Use published CADR as an input, then change the assumptions for your room and local costs. Results are estimates, not test measurements.

CADR room-size estimate

Estimated floor area: 220 sq ft

Three-year ownership estimate

Estimated three-year cost: $359
