Post-Purchase Truths

Levoit: 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.

Coway: What to watch for

  • Hardware Quirk

    Ionizer ("Vital Ion") produces negligible ozone and should be disabled.

    Many asthma and allergy sufferers immediately toggle the optional ionizer off to ensure completely emission-free mechanical HEPA filtration.
