Before you decide

Levoit: What to watch for

  • Hardware Quirk

    No true HEPA H13 rating on recent replacement filters.

    Due to US regulatory naming updates, Levoit adjusted terminology from "True HEPA" to "HEPASmart" on several retail filter packs.

  • Maintenance

    Filter check light does not measure real dirt; it operates on a fixed timer.

    The filter replacement alert triggers every 6 months regardless of whether your room was smoky or pristine, requiring manual reset.

Honeywell: What to watch for

  • Maintenance

    Requires periodic filter replacements to maintain airflow and odor capture.

    Activated carbon and HEPA media gradually saturate, needing replacement once or twice yearly depending on air pollution and pet shedding.
